Experts remind: Going out less, wearing a mask, washing hands frequently, and ventilating more can effectively prevent the new coronavirus.
However, there are many types of masks on the market, and it is very important to correctly judge the masks.
If you want to make an accurate choice, you must start with its raw materials. Today we will learn about the disposable mask filter material.
Currently, the filter layer used for masks is mainly polypropylene (PP) melt-blown non-woven fabric, which is composed of fibers accumulated to form a network-like through-structure, so it has good filtering properties, barrier properties, heat preservation and Adsorption.
The size of PP melt-blown non-woven fibers on the market is 1-10μm, which cannot reach the nanometer level. The pores formed by fiber accumulation are large and cannot effectively collect small particles. For particles with a particle size of 0.3μm, The filtration efficiency is below 50%.
Disposable mask filter material can effectively prevent respiratory infections and prevent haze.
The N95 mask is one of the nine types of anti-particulate masks certified by NIOSH (National Institute of Occupational Safety and Health).
“N” means that it is not suitable for oily particles (the fumes produced by cooking are oily particles, but the droplets produced by people talking or coughing are not oily); “95” means that in?NIOSH ?Under the testing conditions specified by the standard, the filtration efficiency reaches ?95%.
It is a disposable mask filter material manufacturer integrating production, sales and customization.
