Polytetrafluoroethylene (PTFE) material has excellent high temperature resistance, alkali resistance, oxidation resistance, hydrophobicity and non-adhesion properties.
It is widely used in air purification, industrial dust removal, pharmaceutical fields, electronic appliances, clothing fields, etc.
PTFE air filter membrane is made of polytetrafluoroethylene (PTFE) material through special processes such as mixing, extrusion, extrusion, calendering, and biaxial stretching.
It has a microporous structure with staggered fibers, high porosity, small and uniform pore size. Therefore, the PTFE air filter membrane can achieve higher efficiency with lower resistance.
?The surface morphology of the PTFE air filter membrane has a spider web-like microporous structure.
Pores are formed between the microfibers. The arrangement direction of the microfibers is basically parallel to the stretching direction. The junction of the fiber bundles is the node, which is formed by the entanglement of many microfibers.
1.?The membrane pore size is adjustable, and the membrane pore size is evenly distributed to meet different filtration precisions.
2. PTFE material is highly hydrophobic, has low surface energy, and has good non-adhesion. It is easy to remove dust accumulated on the surface of the material, so it can be rinsed with water to restore its performance, achieve reuse, and greatly extend its service life.
3. Surface filtration mechanism, which can easily remove accumulated dust through mechanical vibration or wiping.
4. Excellent waterproof performance, good breathability, wear resistance and water wash resistance.
After composite processing, it can be applied to the surface of various filter materials. The film is laminated on various fabrics and substrates using a special process to become a new filter material.
The membrane has small pore size, uniform distribution and large porosity. It can achieve the purpose of purification and ventilation while maintaining air circulation.
The products can be used for air purification and filtration, industrial dust removal and filtration, etc.
