What is the protective effect of non-woven respirator?

　　Non-woven fabric manufacturers tell you that non-woven fabric masks, dust, metal dust, especially small easily inhaled dust have a certain blocking effect, general gauze masks can only withstand some large particles of dust, but the tiny dust actually can not block, then the non-woven fabric mask protective effect after all how? General Gauze Mask, which is a mechanical automatic filter dust principles, that is, when the dust collision or gauze, through the barrier layer, a large number of dust particles produced in gauze barrier. "However, some studies study fine dust, especially dust smaller than 5 microns, which enters the respiratory system through gauze. For this dust protection there are also some foreign dust masks that work as electrostatic filters on fibroblasts. Dust less than 5 microns passes through the airways, no such filter medium is attracted by static electricity and adsorbed on the filter to capture such a thin material as dust in order to prevent the generation of dust. Like water, like air, which is resistant to fresh fragrance which small flow. When the non-woven mask adhesive surface does not have the shape, such as in the air hazardous substances will leak into the adhesive will not enter the human body respiratory tract. So, no matter how good your choice of mask filter material is. You can't protect your health. Many foreign regulatory standards, staff should be regularly non-woven mask adhesion test. The aim is to ensure that the non-woven mask workers choose the right size and follow the correct step of the mask. Data analysis required at the time of production management system to be small resistance, light weight, wearing health, maintenance of our teachers can choose to use convenient.
