Polytetrafluoroethylene membrane material has changed the filtration mechanism of ordinary filter materials, from the deep filtration mechanism of ordinary filter materials to a surface filtration mechanism.
Compared with other conventional filter materials, the main advantages of PTFE waterproof and breathable membrane are surface filtration, stable chemical properties, high filtration efficiency, thorough dust cleaning, high temperature resistance, corrosion resistance and other characteristics.
In addition, PTFE breathable membrane is loved by everyone for its wide application range, long life, low energy consumption and low cost.
So it is deeply loved by industries such as medicine, clothing, and industry.
The surface of the film is smooth and the friction coefficient is small. It is difficult to form a thick layer of dust on the surface of the film, and the dust can be peeled off naturally.
Dust removal from the film-coated filter material mainly uses the filtration function of the PTFE waterproof and breathable membrane. Dust particles will hardly penetrate the film and enter the inside of the filter material.
It can be seen that the surface filtration mechanism is the advantage of membrane-coated filter materials. Compared with conventional filter materials, its advantages lie in its surface filtration, high filtration efficiency, easy dust cleaning, high temperature resistance, corrosion resistance and other characteristics.
PTFE waterproof and breathable membrane is a polymer waterproof material.
From a production point of view, the technical requirements of waterproof and breathable membranes are much higher than those of ordinary waterproof materials. From a quality point of view, it also has functional characteristics that other waterproof materials do not have.
The porosity of the film can reach more than 85%, and the air can flow smoothly.
The membrane pore size is 0.2-3μm, which can effectively isolate water points, and the waterproof grade can reach IPX7 or above.
Protect electronic instruments from becoming unusable due to moisture or water.
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.
