When the shape of the Spunbond nonwoven Factory is not close to the face, the dangerous objects in the air will leak into the airway from the non-closed place. For the filter material of a good protective mask, the following three conditions should be met. 2) Interception – The larger the particles, the better the effect. At present, a very popular non-woven material in the national standard is a synthetic, electrostatically treated material.3 microns (otherwise 0. When the dust barrier is saturated or the mask is damaged, it is discarded.6 microns). Second, the degree of closeness between the mask and the shape of the face.com/.
Third, comfortable to wear. Those respiratory dusts smaller than 5 microns are attracted by static electricity and absorbed in the filter material during the process of passing through this filter material Dust really plays a role in preventing dust. In addition, many masks adopt an arched shape, which can not only ensure a good adhesion with the shape of the face, but also reserve a certain space at the mouth and nose, which is comfortable to wear.
The most difficult-to-filter particles are simply referred to as MPPS (Most Penetrating Particleize). The non-woven fabric after electrostatic treatment can not only block large dust particles, but also the electrostatic charge attached to its surface can attract fine dust by electrostatic attraction, achieving a high dust suppression efficiency.
4) Gravitationl Settling The larger the particles, the better the effect. through the filter material, blocking it from being inhaled by people. The purpose is to ensure that workers choose appropriate masks and wear the masks in accordance with the correct procedures. Their role is to absorb harmful aerosols, including dust, smoke, mist, toxic gas and toxic vapor, etc. There are many kinds of materials for dust-proof masks, including ordinary fabric, animal hair, non-woven fabric, etc. Nor can it protect your health.Five Theoretical Basis 1) Brownian Diffusion – The smaller the particles, the stronger the effect. Because this size of dust can directly enter the alveoli, it has the greatest impact on human health.
