The company can according to the user’s requirements.
The optimized combination of key technical parameters such as speed ratio, pressure ratio, operating temperature, etc. can realize online control of air permeability, thickness and void ratio according to the ratio and pore-forming medium to meet the different requirements you need. .
The main uses of ptfe base film are as exhaust purification filter materials for waste incinerators and coal boilers, non-metal bearings, plastic fillers and sewing threads for reducing friction. Among them, the filter material is currently polytetrafluoroethylene Application fields of ethylene**.
High-temperature dust filter bags made of polytetrafluoroethylene fiber are sold under the trade name “Jefaya” in Japan and have been widely used as filter bags for municipal waste incinerators.
PTFE base film has good heat resistance and self-lubricating properties, and can be widely used as sealing material for high-temperature liquid transportation pipes and corrosive liquid transportation pipes.
For example, pipe joints in the heating industry used to be made of hemp mixed with adhesive. Now they use PTFE film, which can greatly extend the service life.
The PTFE membrane that has been treated to a certain extent has selective permeability, can selectively transmit gas or liquid, and can be used as a separation material.
For example, the film produced by the graft copolymer of TFE and N-vinylpyrrole is a weakly alkaline membrane that can be used as a permeation vaporization membrane for separation and concentration, such as ethanol and dimethylacetamide in concentrated water. The concentration and separation distillation method cannot separate the azeotrope.
