PTFE filter material is made through special processes such as mixing, extrusion, extrusion, calendering, and biaxial stretching.
Due to the characteristics of ptfe fibrillation, when performing unidirectional stretching (i.e. longitudinal stretching), the ptfe polycrystalline aggregates begin to extend and form some fibrils. The fibrils are parallel to the stretching direction. At the same time, the fibrils The length increases.
The cross-section of ptfe fibrils is wide and thin, its maximum width is about 100nm, and the smallest fibril is ?0.5??1.0nm.
It has high filtration efficiency, good filtration performance and small membrane pore size, which can meet the filtration efficiency level requirements of air filters.
PTFE filter material can achieve surface filtration. This is because the PTFE-coated filter material has a microporous structure and has no through-holes on the surface, so dust cannot enter the interior of the membrane or the base material through the surface of the membrane, so only gas can By trapping dust or materials on the surface of the membrane.
?Product quality is constantly improving, and it occupies a dominant position in the market with its unique and stable performance.
And it has a complete set of domestic advanced production lines, which can be customized according to user requirements.
The key technical parameters such as speed ratio, pressure ratio, operating temperature, etc. are optimized and combined. According to the ratio and pore-forming medium, the air permeability, thickness and void ratio can be adjusted online to meet your different requirements. .
