Mask filter material

Date:2020-07-29 View:79

        For a good protective mask filter material, should have the following three conditions, one is in the mask and the user face close to the case of high filtration efficiency, two is small suction resistance, three is the user feel comfortable. There are many kinds of filter materials, including ordinary fabrics, animal hair, non-woven fabrics and so on. Very popular in the National Standard is an activated carbon felt material.

        Gauze mask structure and human face is very poor fit, many of our great harm to the fine particles will be through the gap between the mask and the face into the respiratory tract to the lungs, its filter material is usually some mechanical fabrics, this filter material to achieve high efficiency, the only way is to increase the thickness, and increase the negative effect of thickness is to make users feel suction resistance is great, feel uncomfortable. The non-woven fabric treated by static electricity can not only block the large dust particles, but also the electrostatic charge attached to its surface can be absorbed by the electrostatic gravitation to achieve a high efficiency. The thickness of the filter material is very thin, greatly reducing the user's breathing resistance, and feel comfortable, thus achieving the good filter material we mentioned before the three necessary conditions. With a good filter material, with the scientific design of the mask structure, the composition of a highly efficient and high-quality mask.
