Filtration is a common method for separating solid particles in liquids. There are many kinds of materials used for filtration in life. Today we are going to introduce one of them, which is PTFE gray membrane.
The film has been continuously improved since its inception. Special treatment is carried out on the PTFE film to greatly improve its firmness and durability. After being compounded with other fabrics, it is widely used in military clothing, medical clothing, casual clothing, fire protection Clothing, anti-biochemical clothing, gas masks, water immersion operations, outdoor sports clothing, shoes and hats, gloves, etc., as well as sleeping bags, tents and other materials.
Using ptfe gray membrane as the filter material, offset paper, aluminum film and other materials as the dividing board, and gluing it with the wooden frame aluminum alloy. It is made of special silicone rubber, odorless, the surface will not harden, and it will not harden over time. There are cracks, stable chemical properties, corrosion resistance, can absorb the stress caused by thermal expansion and contraction without cracking, moderate softness and hardness, and good elastic recovery.
Each unit has been tested by the sodium flame method and has the characteristics of high filtration efficiency, low resistance, and large dust holding capacity.
The ptfe gray membrane is prepared using a unique biaxial stretching technology, which can ensure complete retention of bacteria and other impurities while having a large flux.
The material is resistant to high temperatures, strong acids and alkali, and has wide chemical applicability. When used for gas filtration, it can achieve 100% retention of various phages, bacteria and particles above 0.02um.
PTFE microporous membrane has high filtration efficiency and can meet the filtration efficiency level requirements of sub-high efficiency, high efficiency and ultra high efficiency air filters.
