Currently.
The method for preparing Teflon liquid filtration membrane is the biaxial stretching method.
To put it simply, after the PTFE fine powder and additives are fully mixed, it enters the extruder. The powder is pushed and extruded into PTFE strips, and then rolled into a film under a rolling machine, and then heated and volatilized. The additives are removed and biaxially stretched to obtain a PTFE filter membrane. Due to the effect of stretching, the PTFE fibril structure is separated, forming a special node crack structure.
PTFE film manufacturer specializes in the production of polytetrafluoroethylene microporous membranes. It has advanced PTFE film production lines, coating and composite production lines, which are at the domestic advanced level.
