Process control of ptfe microporous filtration membrane

PTFE microporous filter membrane is a kind of fiber that does not add any other materials and is mechanically stretched to make it A microporous film made by puffing. In production, according to different use requirements, various production process parameters can be reasonably selected, and different process controls can be used to obtain microfiltration and ultrafiltration membranes with different pore sizes and porosity to meet different use requirements.

The surface morphology of ePTFE microporous film has a spider web-like microporous structure. Pores are formed between the microfibers, and 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. The ePTFE membrane is an asymmetric membrane, and the micropore sizes are different on the front and back sides of the membrane.

PTFE microporous filter membranes are generally divided into the following types: air filter membranes, which can be used for atmospheric dust removal, air purification, etc., and are used in various vacuum cleaners, air filters, and purification equipment **Filter material; waterproof and moisture-permeable microporous membrane, which is characterized by good wind resistance and warmth retention. It is widely used in medical, fire-fighting, anti-virus, water-immersed clothing and outdoor sleeping bags and tents, etc.; PTFE bubble point membrane, this film is used Special technology is used to coat various fabrics and substrates to become a new type of filter material.

It is a ptfe microporous filtration membrane manufacturer specializing in R&D, production and sales. The materials of the products produced by our company are all imported raw materials, with high uniformity, stable performance and good breathability.
