Guaze mask, it is the wholesome things of a kind of safety action. It is having prevent dirt, bacterium and prevent the harmful gas such as saliva, liquid, of flying foam protect. It is made with gauze or cotton cloth more. As a result of the virus of new-style coronal shape that erupts this year, guaze mask became ” of the most fervent this year “ popular commodities. Everybody knows to go out now is to adorn good guaze mask, but not be everybody is known, understand guaze mask. So your understanding is close to this already unfamiliar “ companionate ” ?
口罩，是一种防护作用的卫生用品。它有着防灰尘，细菌和防唾沫等有害气体，液体，飞沫的护具。它多以纱布或棉布制成。由于今年爆发的新型冠状病毒，口罩便成了今年最火热的“抢手货”。现在人人都知道出门是佩戴好口罩，但并不是人人都认识，了解口罩。那么你们认识这个既亲近又陌生的“伙伴”吗？
Guaze mask is an everybody a group of things with common features, their member is numerous, also have oneself each make a way. You look, they have KN95/N95, have medical and surgical guaze mask, common and medical guaze mask, PM2·5 guaze mask, activated carbon guaze mask and gauze guaze mask. They have each “ competence ” each, each have each “ characteristic ” . The KN that actually we say is standard of Chinese guaze mask, n is standard of American guaze mask, the number as to the back that follows in them is greater, defend grade is jumped over tall. The KN95/N95 that detailed tells everybody now is belonged to defend one of guaze mask with higher order and degree, it can be effective filter the subtle impurity in air, to be less than 0. It also can accomplish the grain of 2 micron to filter at least 95% ; Medical and surgical guaze mask, it is to regard surgery as special guaze mask, defend grade is differred than KN95/N95 series some, apply to the tall danger environment such as medical treatment outpatient service, lab, surgery commonly. And medical and common guaze mask, also have certain counteractive capacity to bacterial virus, the environment with the not high demand such as commonly used outpatient service, following medical and surgical guaze mask is cure protects the type with commonly used personnel. It follows surgical guaze mask is cure protects the guaze mask with commonly used personnel euqally. And the PM2 that we use daily. 5 guaze mask, activated carbon guaze mask and gauze guaze mask, it is to belong to common guaze mask, have heat preservation and the effect that avoid common bacterium only commonly, new to this precaution coronal is pneumonic do not have very big with full marks / place. Only useful and medical defend guaze mask ability rises to protect action.
口罩是个大家族，它们成员众多，也各有自己的叫法。你看，他们有KN95/N95，有医用外科口罩，普通医用口罩，PM2·5口罩，活性炭口罩和纱布口罩等。他们各有各的“本领”，各有各的“特性”。其实我们所说的KN是中国口罩标准，N则是美国口罩标准，至于跟在他们的身后的数字则是越大，防护等级越高。现在大家详知的KN95/N95属于防护等级较高的口罩之一，它能有效的过滤空气中细微的杂质，对于小于0。2微米的颗粒它也能做到至少过滤95%；医用外科口罩，它是作为手术室专用口罩，防护等级比KN95/N95系列差些，一般适用于医疗门诊、实验室、手术室等高危环境。而医用普通口罩，对细菌病毒也有一定的抵抗能力，常用门诊等要求不高的环境，跟医用外科口罩都是医护人员常用的类型。它跟外科口罩一样都是医护人员常用的口罩。而我们日常使用的PM2。5口罩、活性炭口罩和纱布口罩等，是属于普通口罩，一般只起到保暖和防止普通细菌的作用，对这次预防新冠肺炎并没有很大用满分/处。只有用医用防护口罩才能起到保护作用。
Guaze mask is having so powerful “ competence ” , this as special as its structure is inseparable. Guaze mask, general component is three-layer, have outer, middle-level and lining. They are waterproof layers respectively, filter layer and comfortable layer. Just as its name implies has waterproof layer waterproof action, in can preventing flying foam effectively to enter mouth of the person that adorn; Filter layer, can undertake filtering to entering the air of lung, assure the safety that the person that adorn breathes; The gauze place that comfortable layer is a gentleness is made, with the steam of expiration of place of the person that adorn at absorbing, make sure guaze mask interior is clean and neat. Filter layer, it is a guaze mask is the most important. This one with makings is very exquisite, make with frit gush cloth commonly, it is the core weapon that holds back virus and bacterium. Of a guaze mask defend function has how old depend on this one. N95 guaze mask, medical and surgical guaze mask, the standard that medical and common guaze mask classifications distinguishs according to the function of layer of this frit gush. And in these guaze mask, function wants best to belong to N95 guaze mask.
口罩有着这么强大的“本领”，这与其特殊结构是密不可分的。口罩，一般分为三层，有外层，中层和内层。他们分别是防水层，过滤层和舒适层。防水层顾名思义有防水的作用，可以有效阻止飞沫进入佩戴者口中；过滤层，可以对于进入肺部的空气进行过滤，保证佩戴者呼吸的安全；舒适层则是一层轻柔的纱布所制，用于吸收佩戴者所呼出的热气，保证口罩内部干净整洁。过滤层，是口罩最重要的一层。这一层的用料十分讲究，一般用熔喷布制成，是阻挡病毒和细菌的核心武器。一个口罩的防护性能有多大就取决于这一层。N95口罩，医用外科口罩，医用普通口罩分级的标准都依据这熔喷层的性能来区分。而这些口罩中，性能最好的要属N95口罩了。
Guaze mask has effect, besides the function of guaze mask oneself, still have should learn to adorn correctly guaze mask. We should notice to distinguish a face of light color gauze inside, color is deep is waterproof layer, spread out outside face. The metal is stuck piece at the same time on face, pull guaze mask to chin next, make guaze mask obscures completely the mouth is nose. Be sure to keep in mind to be not taken instead. In addition, the longest use time of guaze mask is 4 hours exceed cannot reuse, should change immediately new. Be sure to keep in mind guaze mask cannot the disinfection of high temperature evaporate that boil and spray alcohol is used again. Such meetings make guaze mask loses safety action.
口罩有没有作用，除了口罩自身的性能，还有要学会正确佩戴口罩。我们要注意区分把浅色纱布朝内，颜色深的是防水层，朝外展开。有金属贴片的一边朝上，然后把口罩拖至下巴，使口罩完全遮住口鼻。切记不要带反。此外，口罩的最长使用时间是4小时超过就不能再使用，要立马换新。切记口罩不能高温蒸煮消毒和喷洒酒精再次使用。这样会使口罩丧失防护作用。
Guaze mask, offer advantage for our life not only, it is especially in war of this new-style and pneumonic epidemic prevention, guaze mask was to remove crucial action —— more it cuts off for us virus, prevent infection, build the strong line of defense that had security of a guardianship life!
