Microporous sterilization filter membrane is a PTFE microporous membrane prepared after stretching. It has a special “electrical junction” connected by tiny fibers. Structure, pores are formed between microfibers, the average pore is about 0.02-15μm, the porosity is about 25%-96%, and the thickness is about 20-100μm. Because its pore size is smaller than the diameter of droplets, but much larger than the diameter of water vapor molecules, and has high porosity, in addition to the excellent properties of PTFE materials, the PTFE microporous membrane also has good hydrophobicity, moisture permeability, and charge storage stability. special.
Microporous sterilization filter membraneSmall pore size, porosity It is adjustable and has excellent chemical stability, high and low temperature resistance, etc. It is an excellent microfiltration membrane material. However, the surface of the PTFE membrane is highly hydrophobic and has poor separation effect on polar molecules. Therefore, the hydrophilicity of the membrane will be enhanced through processes such as sulfonation modification and inorganic filler modification.
It is the manufacturer of Microporous sterilizing filter membrane, which is generally made of polytetrafluoroethylene (ptfe) suspended powder. After puffing and stretching, a microporous film is formed. It has a fibrillar microporous structure, the porosity can reach more than 88%, there are 1.4 billion micropores per square centimeter, and the pore diameter ranges from 0.1μm to 0.5μm. Generally, this film is coated on various fabrics and substrates using special processes to become a new filter material. The produced membrane can be applied to the surface of various filter materials through composite processing, greatly improving the filtration accuracy. It can meet the filtration efficiency grade requirements of air filters from low to high filtration efficiency. Because the surface fibers are very fine, smooth, have a small friction coefficient, do not stick to dust, are hydrophobic, and have stable chemical properties, the dust deposited on the surface can be easily cleaned, and even wet dust is difficult to adhere to.
PTFE membrane technology has always been the core of the business, playing an important role in biopharmaceuticals, food and beverages, semiconductor manufacturing processes, communications and other fields, with hole making capabilities From 0.1μm to 1μm, we provide functional solutions such as fine filtration and sound transmission.
