Polytetrafluoroethylene microporous membrane is a filter membrane made by calendering, extrusion, biaxial stretching and other methods using a special process.
Conventional filter media is difficult to control the initial layer of dust during the dust cleaning process, resulting in low dust cleaning efficiency and short-term dust emission.
Polytetrafluoroethylene microporous membrane changes the filtration mechanism of ordinary filter materials, from the depth filtration mechanism of ordinary filter materials to a surface filtration mechanism.
With better air permeability, it is difficult to form a thick layer of dust on the surface of the film, and the dust can be peeled off naturally.
The characteristics of surface filtration enable all dust in the gas to be collected on the surface of the membrane to achieve surface filtration.
Compared with other conventional filter materials, the main advantage lies in surface filtration, stable chemical properties, high filtration efficiency, thorough dust cleaning, high temperature resistance, corrosion resistance and other characteristics.
Features: 1. Surface filtration, low filtration resistance, easy peeling of the dust layer, solving problems that conventional filtration cannot solve.
2. The pore size is controlled between 0.2~3μm, which can effectively trap dust.
3. The surface of the microporous membrane is smooth, no condensation, easy to clean, maintains dust removal efficiency, and greatly enhances service life.
4. The filter material has long service life, high and low temperature resistance, chemical stability, and no aging, making it highly adaptable to temperature, humidity, and corrosive gases, which is unmatched by current conventional filter materials.
PTFE microporous membrane has a wide range, long life, low energy consumption and low cost.
Specific applications include: power plants, waste treatment plants, steel plants, medicine, electronic appliances, air purification, clothing, etc.
