PTFE membrane

タイトルまたは説明

PTFE microporous film surface morphology is a spider's web of microporous structure. Micro fiber is formed between the pore, micro fiber orientation and tensile direction basically parallel connection; fiber bundle is the node, it is composed of many micro fibers entangled to form. PTFE film belongs to the asymmetric membrane, membrane pore size difference between positive and negative. The cross section of membrane pore size than the surface pore size, and pore size also has the difference, is greater than the transverse longitudinal microporous. The membrane section is a kind of network structure, in the hole of the three-dimensional structure of a mesh connectivity, hole bushing, channel bend very complex changes, there may be multiple micropores formed in a channel, it may be that a microporous and multiple channels. PTFE film composite in a variety of textile fabrics to form a composite fabric, can be used in sportswear, cold-proof clothing, military, fire, public security, health care, and biochemical and other special clothing, shoes and hats, gloves and sleeping bags, tents and other. PTFE film composite in glass fiber, needle felt, P*4 formed on the membrane filter material, can be widely used in chemical industry, iron and steel, metallurgy, carbon black, power, cement, waste incineration and other industrial furnace flue gas filter; PTFE film composite non-woven fabrics can be formed on the air purification filter material, can be applied in the clean room, laboratory, ventilation equipment, purification equipment, medical electronics and other sectors of the air purification.
