Since DuPont of the United States began producing polytetrafluoroethylene in 1945, it has a history of 61 years.
As an important product of PTFE, PTFE microporous membrane is now widely used. The expanded fields range from bioengineering to the clothing industry, from the machinery industry to petrochemicals. In the environmental protection industry, it can not only be used in water treatment projects, but also in air purification. Particle purification.
It can be said that its application scope is quite wide.
1. The smoke and dust emission rate is close to zero, 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 PTFE microporous membrane is hydrophobic, and the adhesion between the dust layer and the filter material is small and easy to split. , it can fall off by its own weight without external force.
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 PTFE microporous membrane 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 production shutdowns are reduced number of times.
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.
