The English abbreviation of polytetrafluoroethylene is ptfe, also called Teflon.
This material is acid-resistant, alkali-resistant, and resistant to various organic solvents. It is almost insoluble in all solvents and is resistant to high temperatures. Therefore, people often combine ptfe with other materials to obtain polyethylene. PTFE composite membrane.
The advantage of the film-coated filter bag** is that it achieves surface filtration. The principle is to trap dust on the surface of the filter bag through a microporous expanded polytetrafluoroethylene film with a smooth surface, instead of forming dust inside the filter material. layer, achieving true surface filtration.
And due to the smooth and hydrophobic properties of PTFE, dust is not easy to adhere, the peeling and dust cleaning effect is very good, and it also has high temperature resistance, corrosion resistance and other properties.
PTFE composite membranes are produced using imported raw materials to ensure finer, cleaner and better uniformity of molecular weight.
It has stable chemical properties, high temperature resistance, corrosion resistance, water repellency, oleophobicity, etc., close to zero smoke emission rate, operating temperature can reach -150℃-250℃, and dust removal efficiency can reach more than 99.99%.
The minimum pore size can reach 0.3um, which can capture most solid particles and liquid droplets.
Therefore, it also has good filterability for special gases with high temperature, high humidity, high corrosion and organic liquids.
