He is an unfilial son who is not as good as others in all aspects, but he always makes a fool of himself by devious ways. He was so angry about the last deficit that he didn't sleep well for a few days! The old man's body is not good, Huo Shi fell into the hands of Huo Guanqi, his son did not have the power to fight, he has accepted his fate. At this time Huo Jianming also wants to touch the bad luck head, is wants to let their big room family later drink the northwest wind?! The more Huo Zehai thought about it, the more angry he became. He pulled out the club from the golf bag beside the wall and pumped it to Huo Jianming. What did you do out there?! You say "Dad!"! You're crazy! Huo Jianming hid and roared on the sofa, but did not dare to fight back. Guan Xin rushed up and clung to Huo Zehai's arm. "How old is he? Why did you beat him?"? You can't say anything well! Huo Zehai forced a few strokes, panting and scolding: "How can I raise such a useless thing as you!"! Everything is not as good as others, and you know how to make trouble all day long! "You are not the same yourself!" Huo Jianming's arm was drawn red, his eyebrows tightened, his face turned red, "I'm not as good as Huo Guanqi, you're not as good as his father, I just follow you!" As soon as Huo Zehai heard this, he was even more angry. He grabbed the club and wanted to pump it again. The aunt outside ran in: "Sir, madam.." "Get out!" The aunt steeled herself and said: "General Manager Huo is here." The old man is in the hospital, and that one is the only General Manager Huo now. As soon as the voice fell, Huo Guanqi came in slowly with Gao Xing, and the hall was slightly full of wolves, which made him more calm and relaxed. I seem to have come at a bad time. Huo Zehai hurriedly threw the club, face big turn, "look up?"? Sit, sit, sit. Is there something wrong. "I want to talk to Huo Jianming," he said. A few people in the hall are stupefied, Huo Zehai returns to absolute being, immediately low rebuke the person on sofa: "Did not hear?"? Get up quickly and take Guanqi to the study! Clean up the shit you've done! Huo Jianming's face was cloudy and bright, and he got up with a calm face and led the way to the study. Gao Xing followed Huo Guan to get up. When they went upstairs, Guan Xin stood beside Huo Zehai and whispered, "He didn't even call his uncle and aunt when he came in." Huo Zehai's hanging heart missed a beat and stared at her angrily: "It's all your baby son's doing!" "Is that my own son?" Said Guan Xin resentfully? It's not your son either. …… In the study. Huo Guanqi was calm as usual, while Huo Jianming's face was severely trampled on the expression of painful feet, which looked a little ferocious. Huo Guanqi came to the door specially, Huo Jianming thought that going abroad was just to frighten himself, long span shelving , but when Huo Guanqi's Gao Xing took out a document and put it in front of him, he knew that this man was real. "Huo Guanqi," he asked in a harsh voice, "can't you tolerate me?!" "Do you need me to remind you of what you have done?" Huo Guanqi was unmoved. As soon as Huo Jianming choked, his eyes flickered and he forced himself to be calm, but he was stared at by the clear eyes and felt guilty. Of course he knew what he had done. He wanted to stir up the marriage between Huo Guanqi and Lu Yan, and in an extremely embarrassing way. Who let all this be because of their marriage? Had it not been for Huo Guanqi's marriage and his family's loyalty to Huo Yishan, which showed that he would not be like Huo Qingyuan, how could Huo Yishan give him power? Huo Jianming thought of this and hated it. As long as they were ruined, they would make a fool of themselves not long after they got married. Can Huo Yishan rest assured that Huo Guanqi? Blame it on those idiots. They can't even handle a little star on the 18th line! Huo Guanqi seemed to know what he was thinking, and his cold voice sounded sarcastic: "Do you think this little action can affect me?" Huo Jianming stiffened. Recognize the situation, even if this farce is really successful, it is only a small fight. Grandpa won't let me go because of this. You go instead. Don't dream. "You-" "Ten thousand steps back, even if he wanted to, he didn't have the ability." Huo Jianming was stunned by his bold words and frowned: "How dare you..." "That's the truth." Huo Guanqi is calm. "Everyone knows the reality except you.". Including Grandpa. Huo Jianming was stunned, and he had never seen such a Huo Guanqi. This cousin has always disdained to put him in the eye, often meet in addition to the cold or cold. But at this moment, Huo Guanqi body reveals the awe-inspiring momentum, just like a superior posture. It's like.. Just like Huo Yishan. As if it was not enough, Huo Guanqi broke Huo Jianming's fantasy by saying, "Grandpa agreed to let you go abroad.". It was his old man's idea that I came. What do you mean? Let Huo Jianming give up and stop expecting to get his hands on Huo. Impossible — "" It doesn't matter whether you believe it or not, you have to go anyway. What Grandpa is willing to give you is added to the trust fund and collected on time, which is enough for you to live a lifetime without worrying about food and clothing. You'd better keep your nose clean, or I'll find a way to keep you from getting a penny. "As for Huo Shi-" Huo Jianming raised his eyes subconsciously, with the last trace of hope remaining in his eyes. HuoGuanQi slightly hook lips, word by word to extinguish the fire: "I'm in charge." …… "Have you been to your uncle's place?" The spirit of people in wheelchairs is not as good as before, and their white hair is much more than before. Huo Guan nodded, "I've been there." "Zhao yuanqing." Did you send someone to the hospital? Huo Yishan looked at him with light in his eyes. Huo Guanqi did not dodge and admitted: "She is not in good mental condition and needs to take good care of herself." "Is she really in a bad state of mind, or do you think she is?" Huo Guanqi met his eyes frankly: "This is the doctor's diagnosis. If you have any doubts, you can let the doctor talk to you." Huo Yishan was silent for a few seconds, the light in his eyes slowly faded, and he closed his eyes. That's all. Then he asked softly, "How is the progress of the ancient town of Xianshui?" "The project is progressing smoothly, and the museum is expected to be completed in one year, and will be an important cultural symbol of the ancient town of Xianshui in the future.". The number of star-rated hotels in the ancient town is also increasing. Originally, one third of the park was planned to be expanded, but after on-the-spot investigation, the project team decided to change it to two thirds. Several plans were put forward, and one of them was selected based on the development and positioning of the ancient town. When Huo Yishan heard this, his expression eased a little. omracking.com

On the one hand, he was surprised that the man could recognize the acupoint so accurately in the dark, but he did not hesitate to put it on his hand to get the pulse of the other side. This kind of skillful and neat response fully showed his deep skill and wit. Had it not been in this dark room, you would surely have found that Xin Jie's skill of grasping five fingers and dividing them into pieces was far superior to the so-called "closing eyes and changing palms". Although he could not see it in the dark, the man who had attacked Xinjie knew that when he grabbed it, the five tendons on his pulse were immediately injured, only to hear him hum, then bang. Xin Jie could not help but take two steps back in horror, because when he grabbed it, it was empty, and the other side did not know what kind of strange move he used, but slipped through his five-finger defense line like a fish and hit him on the lower abdomen. What was more surprising was that the slap was so weak that he felt only a slight pain and was not hurt at all. Just as he was retreating in a daze, the other side shouted, "Shameless old thief, do you still want to kill them all?" His voice was shrill and tender, as if there was still a little child's voice, followed by a violent gasp. Xin Jie was stunned, but his eyes could see a blurred contour, because he had gradually become accustomed to the darkness. Although he could not see it clearly, he could see that the man was half lying on the ground, as if he were seriously ill. "Rub" the ground,Pallet rack upright, the fire folds a flash near the wind, the room suddenly lit up, Xin Jie because the fire in his hands, and the man in the dark, so for a moment can not see the man, but the man exclaimed. Xin Jie bent the fire forward slightly, and immediately found that lying on the ground was a young man with a dirty neck. He looked fifteen or sixteen years old. His clothes were dirty and full of patches. He looked like a little beggar. At this time, he was staring at Xin Jie with big eyes,heavy duty racking system, as if he was infinitely surprised. Xin Jie had been surprised by his strange move just now. At this time, he unconsciously took a step closer with the fire and looked at the man carefully. He was even more surprised in the dark. It turned out that although the man was unkempt, when he looked closely, he saw that his eyebrows were like scratches, his nose was like hanging gallbladder, his lips were red and his teeth were white. Although his face was covered with dust, there was a very delicate skin between his neck, which looked like a rich boy. Then the boy said, "Who are you to the old thief?" Xin Jie was stunned and said, "What?"? What old thief? The boy shook his head and said, "You really weren't sent by the old thief to chase me. Ah, I ask you, didn't you really know I was inside when you came in?" Xin Jie sniggered and said, "Even if I was really sent by an old thief to chase you, I wouldn't necessarily know you were in this temple." But on the mouth answer however: "Where do I know what fierce old thief." The young man seemed to be barely able to speak, Industrial pallet rack ,Drive in racking system, but when he heard Xin Jie say so, he sighed lightly and said, "Then I'm relieved." Suddenly he had a spasm and fell to the ground. With a sigh, Xin Jie went closer and saw that the young man frowned and seemed to be in great pain. Xin Jie could not help bending down with a fire to see what was going on. The boy thought that the pain was so severe that he could not help but shed tears. Two tears flowed down his face and washed away the dust on his face, revealing two snow-white complexions. Xin Jie saw that the boy was clearly a big boy from a rich family, but somehow he was lying in such a desolate and ruined temple like a little beggar, and he was seriously injured. When he saw the young man frowning and sweating, he couldn't bear it. When he reached out and touched the young man's cheek, it turned out to be unusually cold. Suddenly there was a cold hum behind him, and a man said grimly, "Why don't you stop being a shameless thief?" Then a strong wind hit behind Xin Jie. Xin Jie held the fire fold in one hand, only to see his feet across, his body did not move, his head did not look back and pointed to the "canopy" point. The man sneered again, and the gloomy atmosphere made people feel nervous, but Xin Jie wondered why he didn't pay any attention to himself? But in a flash of lightning, with a whoosh, another strong wind grabbed Xin Jie's left shoulder. If Xin Jie pointed straight in, he could hit the other side's canopy, but a palm on his shoulder would kill him. This move was obviously not the person behind him. The other side must have another helper, and the two of them cooperated very well. Xin Jie still stood on his feet, with his back to the enemy, shaking his waist twice, and pointing out four fingers with one hand up and down and left and right in an instant. Just listen to two whoosh, the attack of two people obviously can not succeed, jumped back, and Xin Jie hand holding the folding son did not even shake the fire. Only then did Xin Jie slowly turn around. As soon as he turned around, all three of them gave a cry. It turned out that the two people who had attacked Xin Jie were actually the two people who had met on the road as ghosts, but they did not know why they had gone and returned? The two men were surprised to see Xin Jie clearly. A man on the left gave a cold, dry laugh, and a pair of angry eyes bulged out of his waxy face, and the light of the fire shone on his high red hat, which was even more frightening. The man on the right looked exactly the same as the one on the left, but his complexion was a little dark. Then he said coldly, "Do you want to kill all the dogs of the old thief?" As he spoke, he split out a palm and collapsed a Nanmu offering table beside him. Xin Jie had already seen the two men's flying skills, but unexpectedly this guy's palm strength was also very strong. He also saw that he had been mistaken again and again. Although he knew it was a misunderstanding, he looked up at the two men's fierce appearance and immediately ignored the explanation. He only snorted heavily and turned to look at the young man on the ground. He didn't even look at the two men at all. By this time, the young man on the ground seemed to have endured a sharp pain and was able to speak. Looking at the two ghost-like ferocious men who had seen their relatives, he cried out: "Uncle Jin-" he could not cry any more, and tears gushed out like a spring. The two strange men seemed to get up and grab it together, holding the boy in their arms, stroking his messy hair, and not knowing what they were saying. Xin Jie looked up and saw that the two grimaces of the dead were overflowing with love at this time, and the perverse spirit had just been swept away, as if the bright red hat on his head was not too harsh. The boy was like a child who had been wronged and fell into the arms of a loving mother, crying so that his shoulders twitched and he was very sad. His face darkened a little and he kept whispering,Warehouse storage racks, "Good boy, it's really hard for you, this child. It's really hard for you.". omracking.com

Spirit beasts can actually turn into human form, but also understand human speech, listen to this sentence, and then look at the hand lovingly pressed on the stomach of Bihua Lingjun, probably guessed 7788, all shook their heads to disperse. The little tiger, who had hit his head, was nestled in Chi Sheng's arms. His eyes were fixed on the clothes bulging on Bihua Lingjun's abdomen. He could see that there was a very unusual aura under his clothes, which was much stronger than his own. He whined a few times and buried his nose in Chi Sheng's clothes. In fact, Bihua Lingjun has a fatal problem in raising spirit animals, that is, he likes the new and hates the old, and is always the most precious one he gets. The spirit animals he had raised for a long time all knew about his problem, and it didn't matter if they turned a blind eye. The little tiger had just been raised, but he didn't know it yet. A moment of neglect made him a little disappointed. He lay in the yard in a sullen way, eating only two bites of food. Another little tiger jumped around him and attacked him, but he was still dejected. Bihua Lingjun walked, sat and lay carefully all day, for fear of bumping Ruyi eggs, even sitting in a chair half a beat slower than before. Ruyi Egg was stuck on his body by magic,Pallet rack beams, and it was already absorbing his immortal spirit and growing slowly. Bihua Lingjun was afraid that these immortal spirits were not enough, so he used another magic to increase the immortal spirit injected into Ruyi Egg several times. Bihua Lingjun touched the Ruyi egg and often struggled in his heart. He had not yet decided what kind of spirit beast he was going to hatch. There are too many tigers and lions, cats and dogs are too petty, foxes and ferrets are common, and the sages are not tall enough, and dragons and unicorns are not very fluffy. Bihua Lingjun in the heart of all the four claws of the spirit beast along a time, found that none of them can be completely satisfied, but think of their own headache. At this time the pressure in the heart,Narrow aisle rack, can not let go, so Bihua Lingjun often sigh one or two cold breath. The next day, Bihua Lingjun went to Lingxiao Hall to answer Mao, and all his immortal friends stared at his stomach, their eyes burning. When he entered the ranks at the foot of the jade steps, he was given more space. Taishang Laojun deliberately came around and looked at Bihua Lingjun's bulging clothes and said, "Bihua, be careful from now on.". Don't bump it. "If you really can't, ask the Jade Emperor for leave and go home to take care of yourself." Bihua Lingjun touched the Ruyi egg through his clothes and said, "It's nothing. Just be careful.". Thank you. Thank you. By the way, Laojun, what should I hatch from this egg? Taishang Laojun looked at the bulging piece of clothes again. Touching his beard, he said, "It's still about fate. You can't force it. You should be relieved and don't think too much about it.". But look at this shape, heavy duty warehouse rack ,Pallet rack supplier, the top is sharp and the bottom is round. It is said that in the mortal world, those with sharp abdomen give birth to boys and those with round abdomen give birth to girls. According to the old man, it's a male. Bihua Lingjun naturally knew that Laojun was making fun of him. Presumably, the old man didn't get a good egg to raise his pantothenic acid in his heart. He laughed disapprovingly and said, "According to Laojun, all the eggs in the world only hatch roosters but not hens.". Laojun has been an immortal for a long time. He forgot that the eggs are all pointed and round. When I come down to earth tomorrow, I'll bring you back two catties on the way. Just then, the Jade Emperor went up to the temple, and all the immortals dressed up and bowed down. The Jade Emperor straightened up and looked at Bihua Lingjun. "Bihua Xianqing, are you still used to hatching a spirit egg?" Bihua Lingjun immediately said, "Tell the Jade Emperor that Xiaoxian doesn't think it's a burden. She just needs to be careful." The Jade Emperor nodded his head and said, "That's all right. But you have to be extra careful when you hatch a spirit egg. It's estimated that there will be no big deal in heaven these days. It doesn't matter if you don't come to the palace. You can keep it at ease." Bihua Lingjun listened to the words of the Jade Emperor as if he was sour. At the moment, his whole mind was hanging on the spirit eggs and the good things that he didn't know what kind of spirit animals should be hatched. He was very magnanimous about the teasing words. The eggs were hatching on his own body, and all the immortals were jealous. The Jade Emperor allowed him not to go to the temple, but he was so happy that he obeyed the order that he bowed down and answered. After receiving this immortal life, there was no immortal affair, and Bihua Lingjun was suddenly idle. After leisure, I do not know how, Bihua Lingjun also want to open, what hatched is what, the spirit beast in the Ruyi egg, will not be bad, as long as there are wet dark eyes, soft hair, small four claws, what hatched does not matter. Perhaps it was because of the nourishment of the immortal spirit, and the Ruyi egg was a little bigger than before. Bihua Lingjun was lonely in the house, so he wandered around to visit a small door in the house of each immortal friend. He chattered back and forth. It was nothing more than the egg hanging on his body. After a few months of wandering like this, all the immortals in heaven heard calluses in their ears. On this day, Bihua Lingjun went to Donghua Emperor's house again. Donghua Emperor listened to him and nodded. His neck ached. He took advantage of his time to suggest that he visit Song Xian and Heng Wenqing, who had been banished to live on an isolated island. So, on a sunny morning, Bihua Lingjun, riding a breeze, went to the lonely island and patted the only gate on the island. It was Song who opened the door. At the first glance after opening the door, he fell on the stomach of Bihua Lingjun. His face suddenly changed. He needed to know that Song Xian was an immortal who had risen from a mortal. He was no stranger to the appearance of Bihua Lingjun at this time. Bihua Lingjun greeted him leisurely, "Brother Song, I haven't seen you for a long time. I came to see you specially recently." He grinned and patted Song on the shoulder. "Did you and Heng Wenqing have a good time on the island?" Song Xian looked at his stomach with a dignified expression: "moist.". Brother Bihua, you.. I haven't seen you for some time. How did you get pregnant? Bihua Lingjun gave a dry cough: "It's an egg." He carefully touched the egg body through his clothes. "It's a Ruyi egg from the Jade Inkstone Pool. It took a long time to get it from the Jade Emperor." As he spoke, he swaggered into the door, walked to an open hall, touched the tea on the table and drank it. Just as he was drinking, Heng Wenqing came out of the side door. He saw Bihua at a glance and was stunned. Then he said with a smile, "Brother Bihua, I haven't seen you for a long time. You don't want to be Lingjun. You want to be Linggu. You even have a fetus." Bihua Lingjun laughed twice and said,warehouse rack manufacturer, "Where? I've been teased by all the immortal friends all day long these days. Even you are not kind." He put down the teacup and touched the Ruyi egg on his stomach, and said the cause and effect of the Ruyi egg again. "I don't know what can be hatched," he finally said. 。 omracking.com

What kind of punishment the prince would receive and how things would develop became her second motivation to live after looking forward to Shen Mingqing's bad luck. It was Su Xuehen of Zhiyuyuan who relieved both hatred and doubts. In fact, from Shen Mingqing to the palace, she was very confused. Because in the last life, there was no such thing as Chongxi. In the last life, it seemed that at this time, Steel racking system ,Cantilever Storage rack, the health of Zhenfei Empress was not good all the time. After a period of delay, Zhenfei Empress died suddenly. It was a great blow to Wang Ye at that time.

Original title: How much do you know about the chemical knowledge of KN95 melt-blown fabric in masks? Small masks also have great knowledge. In the face of the epidemic, masks have become a necessity for everyone. Why do small masks play such an important role? Today, we will use chemical knowledge to bring you a new understanding of masks. Our common masks are ordinary cotton masks, disposable medical masks, surgical mask, N95 masks.. Among them, disposable medical masks and surgical mask can prevent respiratory tract infection to a certain extent, but can not prevent haze; N95 masks can effectively prevent respiratory tract infection and can prevent haze; ordinary cotton masks can not prevent infection because the material itself is not dense enough. Disposable medical mask Expand the full text Disposable medical masks use 2-3 layers of non-woven fabric as the filter material of the mask, mainly to prevent infection between doctors and patients or infection caused by inhalation of bacteria in the environment by medical staff. The outer layer of the mask is water-resistant, which reduces the wearer's exposure to pathogens in the patient's blood or fluids. Medical masks without the words "protection" and "surgery" in their names are all ordinary medical masks. This kind of disposable medical mask is generally not required to have a barrier effect on blood, so it is only used in general medical environment. Nonwoven fabric: It is a kind of fabric formed without spinning and weaving, which is only formed by directional or random arrangement of textile staple fibers or filaments to form a web structure, and then reinforced by mechanical, thermal bonding or chemical methods. Nonwovens break through the traditional textile principle, and have the characteristics of short process flow, fast production speed, high output, low cost, wide use and multiple raw material sources. Medical non-woven products are medical and health textiles made of chemical fibers including polyester, polyamide, polytetrafluoroethylene, polypropylene, carbon fiber and glass fiber. surgical mask Standard surgical mask usually consist of 3-4 layers of non-woven fabrics, and the outer layer is waterproof, which can prevent droplets from entering the mask. The middle layer acts as a filter. The inner layer near the mouth and nose is used to absorb moisture and ensure that the wearer's lips are dry and comfortable. The filter element generally uses superfine fiber as a melt-blown nonwoven material. The superfine fibers are randomly arranged to form a large number of tiny pores. The whole mask adopts folding design to improve the fit between the mask and the wearer's face,3 Ply Disposable Protective Face Mask, which can block more than 90% of particles larger than 5 μm. Superfine fiber: also known as microfiber, fine denier fiber, very fine fiber. Generally, the fiber with a fineness of less than 0.3 denier (diameter of 5 microns) is called superfine fiber. The main ingredients are polyester and nylon. The technical process of the melt-blown non-woven fabric comprises the steps of polymer feeding, melt extrusion, fiber formation, fiber cooling, web formation, and cloth reinforcement. Barrier principle The medical surgical mask is composed of three parts, namely a waterproof layer, a filter layer and a comfort layer from the outside to the inside. When wearing, the white non-woven fabric faces inward and the blue waterproof layer faces outward. Outer layer-waterproof layer. Usually needle-punched cotton, also known as polyester needle-punched felt. Polyester material itself is difficult to absorb water, KN95 Face Mask ,free shipping disposable coverall, and then polyester staple fibers are made into non-woven fabrics by needling, water molecules and droplets with strong polarity are difficult to pass through, while non-polar air can be inhaled smoothly. Middle layer-filter layer. The main material of melt-blown non-woven fabric is polypropylene, which is a kind of ultra-fine fiber cloth with static electricity, which can catch droplets and dust. This layer of non-woven fabric is composed of numerous superfine and electrostatically charged short fibers which are interwoven with each other through mechanical force. Droplets and dust are like walking in a maze in the jungle composed of short fibers. Under the action of electrostatic force and Van der Waals force, most of them stumble and adhere to the dense short fibers, thus playing a very strong adsorption role. Inner layer-comfort layer. The comfort layer is a hot-rolled non-woven fabric, but the moisture absorption and air permeability are much better than the other two layers, which mainly ensures that the nose and mouth are moist and improves the wearing comfort. N95 mask N95 mask is also called medical protective mask. "N" means that the mask is suitable for use in non-oily occasions. "95" means that the mask can filter out more than 95% of the dust with a volume greater than 0.3 μm during use. N95 mask is one of the nine particulate masks certified by NIOSH (National Institute for Occupational Safety and Health), which can prevent droplet transmission. N95 is not a specific product name. As long as the product meets the N95 standard and passes the NIOSH review, it can be called "N95 mask". In particular, it should be reminded that the "bacterial filtration ≥ 95%" indicated in the packaging of some brand masks is not equal to the "N95 protection level". Wherein the mask body is divided into an inner layer, a middle layer and an outer layer, the inner layer is common sanitary gauze or non-woven fabric, the middle layer is a superfine polypropylene fiber melt-blown material layer, and the outer layer is a non-woven fabric or ultrathin polypropylene melt-blown material layer. The high-efficiency medical protective mask has the advantages of strong water repellency and air permeability, remarkable filtering effect on micro-virus aerosol or harmful dust, good overall filtering effect, non-toxic and harmless materials, and comfortable wearing. Polypropylene fiber: Polypropylene fiber is a synthetic fiber spun from isotactic polypropylene obtained by polymerization of propylene. Its trade name in China is polypropylene fiber. Of course, after the mask is produced, there is also analysis and disinfection, which can not be used directly after the machine production and processing! Medical masks are sterilized by ethylene oxide! After sterilization, the residual drugs are released through analysis, and then the safety standards are met! Ethylene oxide: Ethylene oxide, an organic compound with the chemical formula C2H4O, is a toxic carcinogen and was formerly used to make fungicides. Ethylene oxide is flammable and explosive, and is not easy to be transported over long distances, so it has strong regional characteristics. It is widely used in washing, pharmaceutical, printing and dyeing industries. It can be used as the initiator of detergent in chemical industry. Difference between N95 and KN95 The standard of N95 and KN95 is that the filtration efficiency of non-oily particles is greater than 95%. Therefore, in essence, the protective effect of these two masks is the same, but there are differences in certification bodies. N95 is NIOSH certification in the United States, while KN95 is domestic certification, which meets the requirements of GB2626 standard in China. Finally, I would like to remind everyone to pay attention to protection, wear masks, wash hands frequently, ventilate frequently, do not eat together, go out less,KN95 Face Mask with Five Layers, do not spread rumors, do not panic, and overcome the epidemic as soon as possible!
