Abstract

The invention publishes a preparation plant for producing polytetrafluoroethylene composite filter membrane, which includes feeding windin gearing, stitching device and control device. The feeding winding gearing includes roller of polytetrafluoroethylene, roller of backing material, roller of composite membrane. The characteristic is that the stitching device includes the roller of rotate speed control device and the roller of cooling. The pressure gearing is fixed on either of the roller of rotate speed control device and the roller of cooling. The heater is fixed on the roller of heating. The cooling device is fixed on the roller of cooling. Both of them have measure temperature component. The composite filter membrane can improve the contractibility and mould greatly and can also holdthe shape and structure of polytetrafluoroethylene composite filter membrane.

Description

technical field

[0001] The invention relates to a filter membrane manufacturing equipment, in particular to a polytetrafluoroethylene supported composite filter membrane manufacturing equipment. Background technique

[0002] Among polymer materials, polytetrafluoroethylene (PTFE) material has outstanding performance; high temperature resistance, acid and alkali resistance, organic solvent, non-toxic and biocompatibility. When the stretched polytetrafluoroethylene microporous membrane is used for gas or liquid filtration, it has a larger microporous membrane than other polymer materials (such as regenerated cellulose, nylon, polyvinylidene fluoride, polyethersulfone). Open porosity, better particle interception and durability and other comprehensive properties, are currently widely used filter materials in chemical, medical, food, electronics and other fields. However, before the filter membrane is actually applied in the form of a folded filter element, the filter membrane ...
