After years of development, ptfe high-temperature filtration membrane, as a new type of membrane material, has been widely used in many fields such as electronics, chemical industry, medicine, military, aerospace, clothing, and environmental protection.
The biaxial stretching process of ptfe high-temperature filtration membrane gives the membrane good void characteristics, but at the same time, the mechanical properties of the membrane have anisotropic characteristics.
This anisotropic characteristic will directly affect the composite of the film and the performance of the composite material.
PTFE high-temperature filter membrane can be compounded on various fabrics and substrates using special processes, and it can become a new type of filter material.
The pore size of the membrane is small, the distribution is very uniform, and the porosity is large. Therefore, the membrane can filter all dust particles including bacteria while ensuring air circulation, thereby achieving the purpose of advanced purification and ventilation.
?????The current production processes of ptfe high-temperature filtration membrane include calendering film method, turning film method and stretching film method.
The stretched film method can be divided into uniaxial stretching and biaxial stretching. Through structural analysis and actual measurement, only biaxially stretched film has a good microporous structure.
