Note that they are called by their first names, without any leadership titles. Small little some clear, and lowered his head to read the newspaper, as if carelessly, "this Zhang Jin likes you very much." It's over! This makes the dead armadilla anxious! He sat down beside him and waved his hand. "He doesn't like me. He doesn't like me!"! Don't get me wrong! You, you don't mess with him- "Oh, the maintenance is terrible!"! The dead armadillo is politically sensitive. Who is sitting in front of her? A serious long poem! Don't ruin Zhang Jin's career with a word from her! Xiao Shao laughed, deliberately not looking at her, slowly turning over the newspaper, "What did I do to him?" Before he had finished, the dead armadillo grabbed his wrist eagerly. "Zhang Jin, oh no, Director Zhang is a very talented and capable leader. The reason why he is very calm to me is that he knows that I am out of my mind.". My ability to work is also general, he does not dislike me, play my strengths, so that I have confidence in the work. It doesn't matter whether he likes it or not. He knows how to use people. Armadillo this insight, to call the white crane Xiao really have a little interest in this Zhang Jin, not for anything else, just because, it can be seen that Armadillo likes him. But, why this up to now, want which man almost can get which man's silly girl, do not lay hands on him? Xiao Shao put down the newspaper and looked at her with a slight tilt of his head. "This Zhang Jin, why didn't you get along with him?" After all, armadilla was an honest girl, and she lowered her head slightly. "Zhang Jin and I are not the same person. If I don't fool around with others, I will think about his mind." Ha ha, the fate in this world. If the armadillo affectedly denied that he had a heart for Zhang Jin at the moment, Bai Hexiao would still be faintly disappointed. However, armadilla said so, you look at her expression again,-faint shame, light desire, shallow regret and exclamation-white crane Xiao suddenly understood that this woman took what to attract people to her more and more difficult to extricate themselves. Greed is there, affectation is there, but not false. It is reassuring, reassuring, and sometimes warm-hearted to show one's true thoughts frankly. The settlement was completed, and Bai Hexiao returned to his home with the only close relative in his thin household register. Pushing open the door of a small courtyard, That's what Bai Hexiao said to Gao. This is my home, and this is your home. Here, before very few people come in, I just want to keep a real private space of their own. Now you belong here, and I will protect you. To tell you the truth, armadis will not be unmoved. She deserves it, though. If you are honest with someone, radio shuttle racking , one day, you will win his honesty and sincerity. Even if he is high above the masses, his "lonely at the top" heart needs warmth and sincere treatment. 84 How not to be a beautiful girl? True, all wishes come true. Her pseudo-father solved all the problems in one night, just for her "want"-I want to marry Han Yingqin tomorrow. All obstacles are swept away. The Yamen asked for his former study as a boudoir. Bai Hexiao personally moved the bed and bedding for her. His eldest daughter has been exhausted all day today. After washing, she will fall into bed and go to bed. Tomorrow she will go to be a bride. Her pseudo-prince father wanted to say that his life was better than that of any other person in the world, but compared with his own daughter, his life was like a bird. The girl fell asleep, closed the door gently, and began to sort out the things from the study outside. If you want to say that the men all over the yamen are all nobles, but they can really live their own lives by themselves. The main thing is that they are all very heavy. If they are not cunning, they must have the most private place to do it themselves. Of course, in the end, these places are deeply marked with "high brand". On the second day, Yanei got up in a daze, probably not fully awake, so that as soon as he opened the door, he saw Bai Hexiao, who was frying eggs with his shirt sleeves rolled up in the small kitchen, he was stunned for a long time! I turned my head for a long time, and the drowsiness was over, and I remembered everything. She was still in his nightgown, with the sleeves rolled up at her elbows and the hem at the base of her thighs. When she calmed down, she went back to the house, put her pajamas on and tied them outside her pajamas. Even if she raised them higher, the legs were still very long. When she came out barefoot, the legs covered the top of her feet. What about the bathroom? Her long hair was loose, a little stupefied, a little out of bed, and she was in ill-fitting pajamas, which were still tied up in pajamas, like a boy scout. White crane Xiao raised the wooden shovel and pointed to the other side, and she walked slowly past. Armadillo gets up every day and moves very slowly. Of course, it's pitiful to say that she has some sequelae from brain surgery. It's really a pleasant scene to say. A man, white shirt, sleeves slightly rolled up at the wrist, a button loose at the collar, slightly low-waisted trousers, belt, delicate waist. Qingcheng's face, especially a demon red between the eyebrows, but sparse and light eyes. The man leaned lazily on the small stove and turned over the fried eggs with a small wooden shovel in his hand. His movements were skilled and somewhat unruly. Live and enjoy life. However, the woman standing at the door of the bathroom ignored this scene. Where's the toothbrush? Like a child, she really wants to "stretch out her hands for clothes and open her mouth for food." Isn't it all ready for you? It's on the sink. "Oh." She went in again. For a long time, she can really grind in the bathroom. White crane Xiao is also really patient, but also qualitative, do not urge also do not look at her. She came out, her hair gathered loosely in a long braid at the back of her neck. She realized that he was getting her something to eat and went straight to the bar in the small kitchen, climbed into the high chair and sat down with her hands on her legs and waited. Because he's still baking. Don't drink milk. She saw him boiling milk. You know, you drink honey water. Give her the honey water from the thermos. A simple and nutritious breakfast was put in front of her. She found that he ate nothing but milk. Later, she learned that her pseudo-father was much more delicate than she was. He was really weaned at the age of six. This weaning refers to sucking Mimi. Later, he was milked to eat. It was even later to say weaning. Xiao Shao is addicted to milk, which is known to the old mothers in Zhongnanhai. omracking.com

Big madam cold eyes swept two young ladies, this two elder sisters in front of the princess is also so arrogant, there is no big elder sister so smooth means of dealing with, only blindly publicize their own noble character. It seems that it is right to let Zhaolan marry into Lingnan Wangfu. "Second Sister, this girl, always loves those poems and songs. She teaches her to take care of the backyard on weekdays, but she always says she's not interested. My concubine also has a headache." However, she did not think that Gu Yanrong seemed to be a different person. I'm afraid she'll have to find a day to find out. Cheng Yiran smiled sweetly and said, "I can't always learn these things well.". My mother has told me several times that I just don't have the ability of my sister-in-law to handle those accounts and trifles in good order. After a short pause and a mouthful of tea, he added, "Madam, the mountains and rivers in the south of the Yangtze River are so beautiful that all the people raised there are exquisite hearts with seven orifices.". The sister-in-law is gentle and generous, the second young lady is also talented and famous, and several concubines in the house are also very well educated. Even the young eight young ladies are good at embroidery. Although her embroidery was not as good as Miss Gu's that day, I felt that she would be a top lady in the future. Words with a little admiration and appreciation, lips are always filled with a faint smile, graceful eyes, although only plain clothes and light makeup, but a pure and soft. "The first lady answered again and again, adding," It's a great blessing for the eighth sister to be appreciated by the princess. But Cheng Fei-ran sighed, frowned slightly, and said, "If it had been a blessing, it wouldn't have hurt her aunt and sister like this.". "It's all my fault. Why did you embroider your handkerchief to make Huan-fang look like this?" As if unintentionally in general, but every sentence seems to blame the big lady in general. Big madam secretly frightened,Warehouse storage racks, one side of the two young ladies impulse to defend their mother, but was Du Zhaolan cold eyes a stare, the heart flashed resentment, but eventually understood the meaning of the elder sister. The first lady calmed down and said, "Princess, the second sister's embroidery is not as good as the third sister's, but she is skillful.". The princess was still thinking about the embroidered handkerchief, so she let the second sister try it. The second sister had also learned from Brocade Niang for some time before. "Is it?" Cheng Huan's face was full of joy, but his eyes were full of cold fog. The second young lady had studied for a few days, but in a few days she knocked over the embroidery box and insulted her mother in every way. Second young lady,Drive in racking system, now let me see how you embroider these ten beautiful handkerchiefs! "This.." The second young lady looked embarrassed. How could she embroider this complicated ten-brocade handkerchief with her skill? Mother, isn't this hurting her? The first lady, however, was very calm and free. She only cast a soothing look in her eyes and said to Cheng, "It's just that the second sister is not good at learning. Her hands are very slow, but she's careful." Cheng Fei-ran smiled and said, "It doesn't matter.". Second Sister, take your time. It doesn't matter. As a result, the ten beautiful handkerchiefs eventually fell on the head of the second young lady. After a hundred turns and a thousand turns, the first lady succeeded in paving the way for the second young lady. Cheng Feiran finished the meal here in Du Zhaolan, and then sent Linglong back to meet Huan. She wanted to wait for Helian to pick her up, but she was afraid that Helian would not come, otherwise she would not put down Linglong and leave. I think I'm afraid of meeting my brother. Linglong some can not save Cheng Fei Ran, Cheng Fei Ran promised her to look for her tomorrow, she was willing to let go, let Cheng Fei ran away. On the way back to Du Fu, Cheng Feiran remembered that he had eaten at the wonton shop a few days ago. On a whim, he got out of the carriage. Hao mother-in-law is still alone, Pallet rack upright ,long span shelving, a pot, a few tables. Seeing Cheng Feiran Yingying coming, she said with a smile, "Today the old woman is blessed again.". Is the noble still like that day? Cheng Feiran was slightly stupefied. The mother-in-law even recognized her. "Yes, thank you, mother-in-law," she said with a shallow smile. Mingxue Suqing didn't want to eat, so they waited on both sides of Cheng Feiran. Several guards stood in front of her mother-in-law's stall. Cheng Fei-ran quickly greeted a few people and said, "You all sit down and stand there. Won't you frighten the guests?"? How can mother-in-law do business? "It doesn't matter," said Granny Hao. "There won't be many guests this time." With these words, the hot wonton just came out of the pot. Granny Hao sprinkled scallions, sesame oil, and a drop of hot pepper. Then she brought it to Cheng Feiran and said, "The old woman planted her own hot pepper. It's very hot. This drop is enough.". Now it's still steaming hot, and I'll eat it while it's hot. "Thank you, mother-in-law," said Cheng Feiran, nodding her head. Granny Hao went back to her pot with a smile, and she was very satisfied with Cheng Feiran. The girl looked extremely luxurious, but there was no trace of arrogance, but she matched Du Er's son very well. Cheng Feiran looked at the hot wonton in front of him, felt a big appetite, and even sprinkled a lot of vinegar. It was sour and spicy, which made her feel very comfortable. A bowl, but also want to eat a bowl, just looked up to say, but surprised to stand in front of a cheerful smile, but also slightly with a playful man. Embarrassed, Cheng Fei-ran wiped the corners of his mouth with his handkerchief and said slowly, "Second Childe." Du Jincheng, however, did not take care of her. He only shouted to Granny Hao, "Granny, two more bowls of wontons." There was a red tide on Cheng's face, and his cheeks burned slightly. "I don't need it," he said. A woman, such a big appetite, is not a joke? "Not for you." Du Jincheng hooked his lips and smiled, and a trace of pondering flashed through his eyes. Cheng Fei ran slightly stupefied, but there is no silver here. Just when she was embarrassed, she heard a hearty laugh. "Honest, my sister is thin-skinned. How can you tease her like that?" Looking sideways, it turned out to be an elder brother dressed in silver. He sat down with the voice, but looked at his sister with a playful face and said, "Sister, why is your face so red?"? Is it difficult to.. "Brother!" Cheng Fei ran more and more embarrassed, blushing cheeks, like a blooming fan (rose variety), delicate and dazzling, people can not help but lock their eyes on her body, unable to move their eyes. Du Jincheng is like this, these days get along, he unexpectedly felt that Cheng Fei ran and his impression of the appearance of the change too much too much. Sometimes she is noble and elegant, sometimes she is cunning and playful, sometimes she is gentle and considerate, and sometimes she shows a touch of sadness, and also shows a hasty look like just now. This woman,heavy duty racking system, as if she could never read. However, he clearly knew that the woman was tough and confident in her bones, just like the red cotton blooming in his yard. omracking.com

Behind her was a woman in a white robe. Her long black hair was scattered, her delicate face was covered with scars of embarrassment, and her white robe was somewhat gray, which made her look very embarrassed. These two men were Angelique and Lispel, who had rushed out of the ruins after a rush. Walk quickly! Aini and I have to stay on the ship to be responsible for watching the ship! We have to get out of here right now! Cried Lispell, with an anxious face, as she ran quickly down the path. Anglie did not say much and nodded heavily. Following close behind Lispell, he cast a last glance back at the underpass. The dark holes of the three passages finally slowly disappeared. Return to the original off-white stone. The black hour hand of the corona was now snow-white. Sniff! A white beam of light suddenly shot out from the tip of the hour hand and soared into the sky. Between heaven and earth, a slender white line was erected in an instant. Anglie turned his head and looked no more. The two men rushed forward quickly, down the mountain road,Pallet rack supplier, turned some corners, and jumped directly when they needed to take a detour at some downhill places. More than ten minutes later. The two finally returned to the beach where the boat had stopped. How is that possible!! Where's the boat? Lispel looked at the empty sea in disbelief. But where the ship had stopped, there was no sign of the ship at all. It's empty. Near the beach, the light blue water rushed up and then receded quietly. The water rushed back to the sea through the black cracks in the rubble. Where's our boat? Lispel ran over and rushed into the sea. I turned around a few times where the boat stopped, but there was no trace. This is a problem. Anglie's face changed slightly. Both of them could not help but associate with the strange scene on the island,Cantilever Storage rack, and if the ship really had something to do with the blue figures, it would be troublesome. Angri went to the beach and crouched down to examine the marks on the ground. Is there any way to contact the ship? He turned to Lispell. Only then did Lispel slowly wake up, and now she had completely lost the kind of indifference she had just begun, and the whole person seemed unusually impatient. Reminded by Anglie, she quickly took out a small golden ball from her waist bag. Zap! The surface of the golden ball suddenly pops up black spikes. Lispell was holding a spike. A gentle twist. Sniff! The golden orb suddenly disappeared from her hand. Draw a golden line straight into the sky. The sound of hissing came from the air one after another, and all the spikes on the ball radiated out in an instant. It flew towards all sides and soon disappeared into the island and the surrounding sea. And Riamras (Angma: Mother of the Morning Light)! Lispel says the activation spell out loud. Suddenly, a thin golden line flew from the left front of the two men. Attached to a golden orb in the air. In that direction! Cried Lispel, heavy duty warehouse rack ,pipe cantilever rack, running straight that way. Anglie nodded and got up to follow. After running along the coastline for more than ten minutes, the two men found their boat under a rocky cliff. The tiny black vessel was stuck between several rocks, and a thin golden line was attached to the sail of the ship. The sea breeze is getting stronger and stronger, and the waves are getting stronger and stronger. The sky was overcast with dark clouds, some of which even turned into black clouds. The sky, which was still at noon, turned into the scene of night. Angelique and Lispel waded to the side of the boat. Lispell rubbed the white ring on her hand. The whole person suddenly emerged at the foot of a white triangle rune array. The amulet rose slowly with her, and soon she was as high as the deck of the ship, and Lispel jumped lightly and stepped on the deck of the ship. Anglie stretched out his hand and pointed to the side of the ship. A piece of silver metal suddenly flew out, grabbed it hard on the side of the ship, and pulled it gently. His whole body immediately took advantage of the force field to push up. He soon climbed up the side of the ship and jumped onto the deck. The boat was deserted and no one was seen. Lispell went aboard first, and by this time she was in the cabin. Soon, she dragged two more people out of the cabin entrance. The two men were two men in dark red leather armor. They are all in a coma at this time. And each of them had his own weapon in his hand, and there was a faint dark red blood on his body. Throw the two men on the deck. One of them is a follower of Eni. They are under the influence of hallucinations. They see each other as enemies. It seems to be the power of the curse. We must get out of here immediately. Lispell looked much calmer now. She took a deep breath and tried to calm herself down more. In fact, you don't have to be so nervous. I think the realization of this curse is conditional. And as it happens, I may have the power to remove the curse. Angley calmly said that after experiencing Yueqin Manor, he was no longer too nervous about the situation, although helpless, but it did not mean that he had no resistance at all. Although I don't know why I'm next to you, I seem to feel much safer. But it's not as simple as you think. Said Lispel in a deep voice. You see She turned her face sideways and pulled back her right collar to reveal the white skin of her shoulders. On the white skin, the black pattern of a circular corona is clearly visible, which seems to be a tattoo. Such a pattern represents that I am now cursed by serious evil thoughts. There are many such patterns on my body. Lispel said with a straight face, "Now we have to take the boat out, park it in the original position, and wait for Milisa Iny to come back for half an hour at most. If we can't wait for anyone, we must leave immediately!" Andre looked at the pattern on her shoulder with some surprise. He shook his left hand gently. The hallucinatory mark on his hand seemed to make him immune to the situation. It seems that the bloodline of the ancient harpy played a role,Narrow aisle rack, and the ancient harpy was born to manipulate illusions. Most of the attacks that attach to hallucinations are almost ineffective against them. Angelique was about to speak. Suddenly there was a scream from the depths of the island. It's Melissa! Lispell turned her head sideways, startled, and looked toward the sky in the depths of the island! Oh my God She suddenly covered her mouth tightly and looked incredulous. omracking.com

"I'm going to boil the medicine for Xiao Lin, and you two have a rest here now." Tang Mu'an is in a good mood, look at the two of them sister and brother love, also embarrassed to disturb here, so found an excuse to leave directly. After Tang Mu'an left, Bai Xiaolian stood in front of him with Bai Xiaolin, "Xiao Lin, your sister is so good to you, should you listen to your sister?" "Well," Bai Xiaolin nodded seriously, fleshy little face is full of smiles, all is the trust of her sister, "Xiaolin will be good to her sister in the future!" "Then Xiao Lin must become a man of indomitable spirit. Only by becoming a man of indomitable spirit can you get everything you want. But don't have the idea of having children. That's all wrong. That's what girls should do. Xiao Lin is a big man, do you know?" The child in front of him was still young, and Bai Xiaolian did not know whether he could understand what he said. But the child should have started education when he was young. Bai Xiaolian felt that it was a mysterious thing for men to have children in this world. Since Bai Xiaolin was his younger brother in this world, of course, he should be well disciplined according to his own mind. Parents have died, as the elder sister is his day, this ancient times all have elder brother such as father this sentence, then oneself this elder sister's words Bai Xiaolin should listen to more. Think of the dry face of the sea, Bai Xiaolian's smile has become a little bad, she would like to see, their tune Bai Xiaolin. Teach like a man of indomitable spirit. How can a conceited man accomplish his task if he abandons his identity as a brother. At the thought of the dejected appearance of the sea and sky,Pallet rack beams, Bai Xiaolian felt a burst of comfort in her heart. There are few men who dare to refuse her, and there are few men who can refuse her. As for the man who refuses her, he must pay the price. Bai Xiaolin is only five years old, hear these words, in fact still some ignorant, but see elder sister seems to be very serious appearance, he also seriously nodded. After chatting for a while, Tang Mu'an came out and saw Bai Xiaolin's confused face. He couldn't help asking,Steel racking system, "What's wrong with Xiaolin?" "My sister made me a man of indomitable spirit, but I don't know what a man is." Little face wrinkled up, Bai Xiaolin is still a little confused, "is it a man when he grows up?" Tang Mu'an couldn't help laughing, and when he wanted to answer, he was interrupted by Bai Xiaolian's charming laughter. Ha ha ha, look at what you said ~ "a little bit of Bai Xiaolin's nose, Bai Xiaolian said," the so-called man of course is to have a good family and career, men should be self-reliant, like those brothers, is no ability, will only rely on their husbands, marry and have children at home embroidery, such a man is useless man, Xiaolin should remember, Industrial pallet rack ,warehouse rack manufacturer, can not become such a man. " Bai Xiaolian just instilled Bai Xiaolin according to her own thoughts, but did not find that Tang Mu'an on the side had tightened his brows. This brother and man can only be regarded as the same gender, and after they get married, they are also in a state of division of labor and cooperation. Although there are people of these three genders in the world, there is no discriminatory attitude towards each of them. There are brothers who go out to do business, and there are women who go out to do business, but the number is slightly less than that of the stronger men. Bai Xiaolian's words, on the contrary, directly labeled the elder brother as useless. Brother, although most of the body is relatively weak, but the brain is not good, do most of the things are mental work, there is no useless thing. But Xiao Lin is a brother. From an early age already know their own gender, Bai Xiaolin suddenly heard the news that they are useless, the whole little people are somewhat stupefied. What my sister said was a complete denial of him. "You don't frighten him," a gave Bai Xiaolin to hold up, Tang Mu an expression some strange look at Bai Xiaolian, let her calm down for a while, then gently comfort, "Xiao Lin is very smart, not good for nothing, you are just sick now, and so on after you recover from illness, you can read a lot of books, but also when the master ~" The favorable rating, which had already risen to more than 60%, immediately dropped by 3%, and Bai Xiaolian was also frightened and did not dare to act rashly for a while. Biting her lip, Bai Xiaolian covered up the dark light in her eyes, but she was very upset. She was a top tasker. Every task I did in the past was to get the man in a month. But in this world, I have been selling sugar water for two months, and the favorable rating has only risen to more than 60%, and it may go down. Feel that this is really not good, Bai Xiaolian took a deep breath, the heart has another way. Sure enough, we still have to have a relationship at the beginning. In this closed and backward era, as long as we have the reality of husband and wife, is it not easy to get it done later? Ignoring the danger tips given by the system, Bai Xiaolian went into the kitchen in silence and mixed some medicine into the food she cooked tonight. She has been vegetarian for more than two months, and her body is already empty. It's empty 。 Even if the twisted melon is not sweet, it must first quench your thirst. Although the blue and white side can not move, the data of the woman is in hand. It doesn't matter if you don't look at it, but you still feel a little surprised. The woman has been doing the task for more than ten years, but her system is not a formal system. In the current pattern, all systems are certified, and each type of system is divided into regions. Bai Xiaolian's system is a system that has been eliminated by generations, because the way it gains experience points is too indescribable. However, the two are in a state of parity, the so-called Goldfinger does not exist, the most direct way is to interrupt Bai Xiaolian's business,Narrow aisle rack, so that she can not continue. Although this is a bit immoral, the competition in the industry exists at any time. The other party has opened the system, so you are not polite. omracking.com

Originally published as Stop buying and wearing the wrong thing! These masks can prevent COVID-19. During the epidemic, we should not relax and avoid participating in gathering activities. When you go out, you must wear a mask. However, there are so many masks on the market that some people are confused, and many people are confused: what is the difference between disposable (protective) masks and disposable medical and surgical mask? What is the difference between medical masks? Let's popularize it for everyone. Let's take a look! Comparison of mask implementation standards Comparison of mask implementation standards Expand the full text Difference between disposable (protective) mask and disposable medical and surgical mask Difference 1: Disposable (protective) masks are made of two layers of non-woven fabrics, while disposable medical and surgical mask are made of one or more layers of non-woven fabrics. Difference 2: The process is different. The main production process of disposable (protective) masks includes melt-blown, spunbond,Full Body Disposable Coverall, hot air or needling, etc. It is a protective textile. The disposable medical and surgical mask is made of two layers of fiber non-woven fabrics specially used for medical and health care, with a layer of filter dissolved spray cloth in the middle, welded by ultrasonic wave. Disposable medical and surgical masks have the effect of resisting liquid,KN95 Mask with Fast Shipping, filtering particulate matter and bacteria, while disposable (protective) masks are mainly used to prevent dust and filter particulate matter. Therefore, during COVID-19, it is better to use disposable medical and surgical mask and N95 protective masks. Difference 4: The effect is different. Disposable medical and surgical mask can block airborne viruses with a diameter of less than 5 μm or close contact with droplet transmission viruses, but disposable (protective) masks can not. Classification of medical masks Medical masks are divided into disposable medical masks (also known as ordinary medical masks), 3 Ply Disposable Protective Face Mask ,Medical Disposable Coverall, surgical mask and medical protective masks. What is the difference between these three kinds of masks? Difference: The prescribed standards are different. The shapes of disposable medical masks and surgical mask are basically the same, while the shapes of medical protective masks are all duck-billed. The performance and use places are different, especially hospitals have strict use specifications. According to the performance level, the order is medical protective mask > medical surgical mask > ordinary medical mask. ① Medical protective mask: ② Disposable medical surgical mask: It refers to a mask that meets the relevant technical requirements of the pharmaceutical industry standard YY 0469-2011 surgical mask, which can block particles larger than 4 microns in diameter. It covers the mouth, nose and jaw of the user, and provides physical protection to prevent the direct penetration of pathogens, microorganisms, body fluids, particles, etc. This kind of mask generally has a filtration efficiency of more than 30% for non-oily particles and more than 95% for bacteria. Surgical mask also has the requirement of synthetic blood penetration (which can be simply understood as impermeability). When making masks, enterprises usually divide them into three layers: the internal absorbent layer, the middle filter layer and the external waterproof layer. Each layer has a special function, which is often a disposable mask worn by clinical medical staff in the process of invasive operation (usually surgery). ③ Disposable ordinary medical mask: It refers to a mask that meets the relevant technical requirements of the relevant registered product standard (YZB) or the recommended standard of the pharmaceutical industry "YY/T 0969-2013 Disposable Medical Mask", which is suitable for covering the user's mouth, nose and jaw, wearing in the general medical environment, and blocking the oral and nasal exhalation. Generally, it can not guarantee the filterability of pathogenic microorganisms and dust, and is generally used for routine nursing in hospitals to block the daily cross infection between medical staff and patients. !!! Remind again During COVID-19,Full Body Disposable Coverall, It's best to use Conforming to the standards of the pharmaceutical industry YY 0469-2011 surgical mask.

Original Title: History of Russian (Soviet) Fighter Development: MiG 25 Fighter When it comes to the fastest aircraft flying today, many people think of the SR-1 Blackbird strategic reconnaissance aircraft of the United States for the first time. In today's era when Mach 2 is everywhere and Mach 1 is not as good as dogs, all countries are studying higher and faster aircraft. The US Blackbird strategic reconnaissance plane has a maximum flight altitude of 300 meters and a maximum flight speed of Mach 3.3. This speed explains what is called the world's martial arts. It has never been shot down in more than 4,000 missile attacks. At that time, the Soviet Union, as a bitter rival of the United States, did not like the arrogant United States, so the MiG 25 came into being. Expand the full text How scary is the MiG 25? And how did you become the Blackbird's nemesis? The MiG 25 fighter uses a new aerodynamic layout different from conventional fighters, fastest dth hammer , with two-dimensional inlets on both sides, cantilevered high-wing twin vertical tails, and a simple straight-line fuselage shape, which further reduces the drag of the aircraft. The fuselage material of the MiG 25 must be resistant to high temperatures at speeds up to Mach 3.3 per hour. The fuselage surface of the fighter must be able to withstand the extremely high temperature of 300 degrees Celsius, in which conventional aluminum alloy simply can not withstand, in this case, the MiG 25 fighter has to use stainless steel with better high temperature resistance. It is said that when Israel saw the MiG-25, there was no way to intercept it, because at that time Israel's most advanced missile speed was less than Mach 3, and it could not catch up with the MiG-25 at all. This also surprised both Israel and the United States. After all, if the Soviet Union attacked it at that time, there would be no room for defense.

Original title: Precise drilling technology is the first thing to learn in woodworking technology. Introduction to woodworking drilling tools Precise drilling techniques are the first thing to learn in woodworking. Modern technology has made it easy to do. The traditional drill is a twist drill. The drilled sawdust can be carried out of the hole by the drill bit. Holes can also be made by the scraping action of the spade drill, which is specially designed for power tools. There are also hole saws, aircraft drills, hole openers and other modern drill bits to bring you a lot of convenience. Power tool drilling The electric drill is one of the earliest electric tools. Then the curve saw, circular saw, belt sander and other tools are derived. It is hard to imagine how a modern woodworker can work without an electric drill. The electric hand drill can also be easily mounted on the drill frame to provide accurate positioning and verticality. Most electric drills use a drill Chuck to grip the drill bit. They are distinguished by power and clamping range, e.g. 500 W, clamping up to 10 mm or 13 mm. The advantage of the spade drill is that large holes can be made: usually holes from 6mm to 38mm can be made. The spade drill requires only a small amount of torque to operate, but some say it is only suitable for drilling with ordinary precision because it distorts the wood fibers. However, it has been widely used. Prefabricated holes are usually not very large in size (less than 6 mm). There are also some special prefabricated hole drills, such as hinge drills, which are specially used to drill prefabricated holes for hinge/hinge installation. Electric pistol drills are becoming more and more common, although they are obviously less powerful than ordinary electric drills. Their advantages are that they are easy to carry and use,Mining Drilling Equipment, the voltage is between 3.6 and 24V, and they are low-risk power tools. The fastest charging time can even reach more than ten minutes. They are suitable for long hours of field work or work in humid environments. Drill chucks were also replaced with quick drill chucks. And they can also be used as electric screwdrivers. With some accessories, they can be extended to more uses. Expand the full text 1. Twist drill is used for ordinary drilling. 2. Three-point woodworking drill can be accurately positioned. 3. The flat drill can open large holes. 4. The reamer is used to make the counterbore to accommodate the screw head, or directly use the countersink drill to complete the operation at one time. 5. The cork drill can be used to make short corks to fill the holes of screw holes. How to drill a hole with an electric hand drill There are many kinds of drill bit structures, and the reasonable structure of the drill bit must meet the following requirements: ① The cutting part suitable for drilling conditions must have normal angle and size; (2) the chips can be separated freely during drilling and can be discharged out of the hole in time with the formation of the chips; (3) the cutting edge can be conveniently sharpened for a plurality of times, and the angle value and the main dimension parameters of the cutting part after sharpening are not changed; ④ Maximum productivity and good processing quality. The structure of the drill is determined by its working conditions: the drilling direction relative to the fiber,Tapered Rock Bit, the drilling diameter, the drilling depth, and the required machining accuracy and productivity. The following common drill structures and their applications are highlighted. (1) The end of the cylindrical head center drill is cylindrical, with two cutting edges and a spiral groove, as shown in Figure 5. This drill is mainly used for drilling shallow holes, but at higher feed rates, the depth of the hole is deeper than that of the spade drill. (2) Drill the circular countersink bit in the center of the circular countersink and the serrated countersink, as shown in the figure. It has two main cutting edges and two other circular cutting edges along the cutting circle, namely the circular sinking cutting knife, Borehole Drill Bits ,rock drilling tools, which is used to cut the fibers first and form the side surface of the hole. The sinking cutting knife protrudes 0.5mm above the horizontal plane of the main cutting edge. As shown in the figure, the serrated undercutting bit has serrated undercutting blades distributed almost along the entire periphery of the bit, and the bit has only one horizontal main edge. These two kinds of drills are usually fixed on the cutter head, and the drill shank is cylindrical. They are mainly used for drilling shallow holes, corks and plywood holes. (3) Sawtooth hole-digging drill: (4) Spoon drill: (5) Auger: (6) Twist drill: (7) Reamer: (8) Carbide drill bit: Use a drill rig What are the woodworking drill bits we usually use? From my personal point of view, the twist drill is used relatively more. Twist drills are also divided into ordinary twist drills and cobalt-containing twist drills. Of course, the people who use cobalt-containing twist drills are wrong, because the price is more expensive. Twist drill Secondly, it is estimated that there will be several rows of drills. As the name implies, it is dedicated to the row of drills. Row drilling can be divided into left and right. Some friends also say positive and negative. Usually, the right turn is used more. That is, positive rotation, or positive rotation. The most common specifications used for row drilling are 8mm, 10mm and 15mm. Row drill positive and negative A lot of woodworking hole openers are used. Hole openers, as the name implies, are used to open holes. Hole-openers are usually 10 mm in the smallest and 100 mm in the largest. This drill bit is used on a bench drilling machine. Industrial grade hole opener 80mm There is also the square eye drill, which is used by relatively few friends. Not much to say here. All kinds of woodworking drill pictures, there must be something you haven't seen. Drill, straight shank twist drill, center drill, woodworking drill, etc., combined salad knife, threaded shank external drill, double-layer step drill, row drill, dovetail mortise knife, wooden plug knife, row drill quick connector.. A square hole drill is a special square hole, keyhole drill bit used on a square tenon machine, if there is no square tenon machine. On the bench drill and electric hand drill, first use the drill core to open a few more holes,down the hole bit, and then use the jacket of the square hole drill to knock slowly.
