Today, the editor will introduce to you a very popular mask. This mask is perfect for wearing in hazy weather. It can very effectively block harmful gases in the air, such as PM2 .5, and other very fine dust, bacteria, etc. in the air.
It is a mask made of ptfe mask film.
The mask membrane has a three-dimensional mesh structure with no through holes.
The porosity and pore size distribution are important indicators for measuring films.
The porosity of the film is generally between 80% and 95%. A high porosity will increase the ventilation; the pore size distribution is concentrated, indicating that the membrane pore size is uniform.
With special production technology, different pore sizes can be controlled for different materials to achieve high-efficiency filtration.
The respiratory impedance of ptfe mask film is only 60-70pa, while ordinary melt-blown non-woven masks are as high as 120-250pa. In comparison, the breathability of film masks is already very good, but it certainly cannot be compared with not wearing a mask.
The wearing comfort of a polytetrafluoroethylene film mask is mainly determined by the air permeability and moisture permeability of the mask.
Thin film masks have higher air permeability due to their material characteristics of high uniform distribution of holes; coupled with the moisture-proof and moisture-permeable characteristics of film materials, they can give users a more comfortable breathing experience.
We are a manufacturer specializing in the production of PTFE mask membrane materials. In the field of industrial sewage treatment, we have the characteristics of “uniform and stable, high efficiency and low resistance, long life, customizable, easy cleaning and maintenance” and are accepted and loved by the majority of enterprises.
