Since the new coronavirus pneumonia is mainly transmitted through the respiratory tract and close contact, wearing a mask is like setting a “filter barrier” for your respiratory system. The same is true for masks, which are mainly blocked by a filter membrane inside. Viruses, this filter membrane plays a decisive role in protection. It is the PTFE nano mask filter membrane.
P series masks mainly protect against non-oily suspended particles and oily suspended particles, and there is no upper limit on time.
During the mask testing process, 0.3μm sodium chloride particles or aerosols of the same nature are mainly used as the testing medium. After pre-treating the mask to be tested for 25 hours under specified environmental conditions, the test medium flow rate is 85L/min.
The index requirements for respiratory impedance are: inspiratory resistance does not exceed 350pa, and expiratory resistance does not exceed 250pa.
PTFE nano mask filter membrane is a polymer waterproof and breathable material.
From a quality perspective, it also has functional features that other waterproof and breathable materials do not have.
The porosity of the film can reach more than 85%, the air can flow smoothly, and the film pore size is 0.2-3μm.
Compared with other breathable filter materials, it has excellent air permeability. It is difficult to form a thick dust layer on the surface of the film, and the dust can be naturally peeled off.
It is a ptfe nano mask filter membrane manufacturer that specializes in R&D, production and sales.
Our company is different from other manufacturers.
