What does the grade of a protective copper mask
mean, and what is the difference in filtering? Different brands have different factory inspection standards for dust masks. The protection level of dust masks is directly related to the filter material used by the copper mask and the method of filtering dust. Theoretical analysis of dust filtering with dust masks, there are five main methods of filtering dust, including Brown motion, interception, inertial collision, gravitational attraction and electrostatic attraction. Different dust filter methods have different effects on the diameter of dust filter. Why is it said that the higher the protection level of dust masks, the smaller the diameter of dust, the effect is not necessarily ideal? The main reason is that the filter materials of dust masks made by manufacturers have not been rationalized. For example, medical surgical masks are usually made of non-woven fabrics. They usually use interception methods to protect people from viruses and blood, but the interception can only be effective on larger particles; another example is medical protective masks, which mainly use electrostatic adsorption. The protection level is also higher for tiny pathogenic microorganisms. Medical Technology Co., Ltd. is committed to the research, development and production in the field of health.
