Microporous Filtration Membrane is made by utilizing polymer chemical materials, pore-causing additives coated on the support layer after special treatment. In the application of membrane separation technology, microporous filtration membrane is one of the most widely used membrane varieties, which is simple, quick to use and widely used in many fields such as scientific research, food testing, chemical industry, nanotechnology, energy and environmental protection. Microporous filter membrane is mainly made of refined nitrocellulose, add appropriate amount of cellulose acetate, acetone, n-butanol, ethanol, etc., hydrophilic, with non-toxic hygiene, is a kind of porous membrane filtration materials, pore size distribution is relatively uniform penetrating microporous, microporous rate of up to 80 ‰ absolute pore size. Mainly used for aqueous solution filtration, so also known as aqueous membrane.
Pore size is relatively uniform, high porosity, no media shedding, thin texture, small resistance, fast filtration speed, adsorption is very small.
Flammable, should pay attention to sealing, moisture-proof, fire prevention when preserving.
Microporous filter membrane, there are hydrophilic and hydrophobic.
Microporous filter membrane is a very thin filter membrane with a porous sponge-like structure. The common pore size ranges from 0.1 micron to 10 micron. Nowadays, the manufacturers of microporous filter membranes categorize them according to their morphological differences:
Flat Sheet Membrane (FlatSheetMembrane), Hollow Fiber Membrane (HollowFiberMembrane) and Tubular Membrane (TubularMembrane). Among them, the flat paper-type filter membrane can be further subdivided into "unsupported flat paper-type filter membrane" (Unsupported) and "supported flat paper-type filter membrane" (Supported) according to its structural differences. Depending on the technology required for the manufacturing of both, the production process of "Unsupported Flat Sheet Filter Membrane" is more sophisticated and complex than that of "Supported Flat Sheet Filter Membrane".
