5 things to know about ptfe microporous membrane

PTFE microporous membrane is a filtration membrane made of polytetrafluoroethylene as raw material and made by biaxial stretching technology.

The main feature of this filter material is surface filtration, which has high filtration efficiency and improves the problems of increasing filtration pressure and high concentration of fine dust emissions that often occur in traditional filtration methods.

PTFE microporous membrane-coated filter material has the following advantages: 1: Close to zero smoke and dust emission rate, and the dust removal efficiency can reach more than 99.99%.

The minimum pore size of the film can reach 0.3um, which can capture most solid particles and liquid droplets.

2: The dust layer formed by filtration is easy to split, and the filter material has good air permeability.

The pre-coated filter material relies on a thin film to capture dust particles. The dust layer can only be formed on the outside of the filter material film. The film is hydrophobic. The adhesion between the dust layer and the filter material is small and is easy to separate. Under the action of external force, it can fall off by its own weight.

If it is blown back, it can be completely removed. If an antistatic polytetrafluoroethylene film is used, the dust will be easier to peel off and the dust will be cleaned more thoroughly.

3: Due to the good air permeability of the filter material, the pressure difference is reduced, the power consumption of the fan is reduced, the service life of the filter material is extended, the startup rate is increased, the dust removal workload is reduced, and the number of production shutdowns is reduced.

4: Due to thorough dust cleaning, the filtration time can be extended, the dust cleaning cycle can be extended, and the number of dust cleanings can be reduced, resulting in less equipment wear and less maintenance.

5: Wide applicability.

PTFE microporous membrane has stable chemical properties, high temperature resistance, corrosion resistance, water repellency, oleophobicity, etc.

Therefore, it also has good filterability for special gases with high temperature, high humidity, high corrosion and organic liquids.

So this filter material is widely used in metallurgy, chemical industry, coal, cement and other industries.
