The membrane material of Teflon filter membrane manufacturer is made of polytetrafluoroethylene. It is expanded and stretched to form a microporous film. This film is laminated on various fabrics and substrates using a special process. It becomes a new type of filter material with small pore size, uniform distribution and large porosity. While maintaining air circulation, it can filter all dust particles including bacteria to achieve the purpose of purification and ventilation.
? Compared with other high-efficiency filtration materials, Teflon filter membrane manufacturer’s membrane material has a higher PF value and good filtration performance.
The membrane pore size is small, and the material has undergone high-temperature heat setting treatment, and the microporous structure is stable, so it can effectively block dust particles at high wind speeds.
The surface morphology of Teflon 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 cross-sectional micropore size of the membrane is larger than the micropore size on its surface, and the vertical and horizontal micropore sizes are also different, with the longitudinal micropores being larger than the transverse ones.
The cross-section of the membrane is a network structure. The three-dimensional structure of the pores has very complex changes such as network connectivity, hole nesting, and channel bending. Teflon microporous membrane is a flexible and elastic microporous membrane. The porous material has high porosity, uniform pore size distribution, and is breathable and impermeable.
The Teflon filter membrane manufacturer specializes in the production and sales of Teflon membranes and various types of membrane-coated filter materials. The company can also meet user requirements.
The key to the technology is the optimized combination of speed ratio, pressure ratio, operating temperature and other parameters. According to the ratio and pore-forming medium, the air permeability, thickness and void ratio can be adjusted online to meet your different requirements. .
