1、The Introduction of Face Mask Face mask, generally speaking, it can be divided into 2 types: air filter face mask and air supply face mask. It was specially designed for peoples health, in order to filter the invisible and visible material which is harmful to body. Thereby, it doesnt bring the negat
2、ive effect. Face mask hasthe filtration effect on the air that get into the bellows. When the respiratory infectious disease comes, wear face mask has a good effect during you work in the dust environment.Thus, both sides can not be used interchangeably, the outer layer of contaminated soil will be
3、otherwise when directly inhaled close to the face, while a source of infection. When not wearing masks, should be folded into the envelope clean and close to the nose and mouth of a face in the folded, should not casually into the pocket or hung around the neck. Material: Non-woven filter paper (fil

Disposable masks are produced with three layers made of non-woven fabrics and filter paper

Up to 99% filtration efficiency BFE is particularly suitable for electronics factory;Disposable activated carbon masks with 28 grams non-woven surface, the middle layer is the first anti-bacterial filter paper filter bacteria from 99%
7、to, bacteria play a role in preventing the virus harm; the middle of the second layer is adopted new efficient adsorption, filtration materials - carbon fiber, activated carbon cloth is made with anti-virus, deodorant, filter bacteria, dust resistance and other effects;3. disposable masks in the pro

Respirator can be used in a hospital environment respiratory protection against all kinds of pathogenic microorganisms, it is a health care occupational protective measures. Strictly speaking, even if you select a quali

13、nfections. A survey showed that using ordinary sterilized gauze masks to be cleaned every day use only has a relatively good protective effect, but requires daily cleaning and autoclaving medical personnel may not be able to do, and disposable masks because of its convenience in clinical the use of
14、a very wide range. Disposable masks recently applied more widely, but its bacteriological outcome is worrying, high bacterial content within the mask, the outer bacterial content is also high, a longer time-use disposable masks, breathing mist easily soaked masks while masks once wet, it will lose t
15、he role of bacteria isolation barrier.Time for wearing masks had done some related test, the test results show that the time to wear masks a significant impact on its protection: wear the longer, the worse their protection, a relatively high rate even with the filter bacteria, but within masks, the
16、total number of foreign bacteria significantly increased the phenomenon, so its protection is also worrying. According to our findings, the best use of time disposable medical masks is 2 h, filter bacteria rate can reach more than 95%. Studies have shown that after a high carrier number morning care nurse masks recommended medical rounds completed in the morning, after the completion of the first one health care, it is to replace a mask, and then the subsequent medic
