Micropore filtration technology began in the mid-19th century. It is a membrane that uses static pressure difference as the driving force and uses the “screening” effect of the mesh-like filter media membrane to perform separation. process. Membranes that implement microporous filtration are called microporous membranes. The microporous sterilizing filter membrane produced is also one of them.
Microporous membrane is a uniform porous film with a thickness of about 90 to 150 mm and a filter particle size of 0.025 to 10 mm. time, the operating pressure is 0.01~0.2MPa. Uniform pore size and high filtration accuracy. It can trap all particles in the liquid that are larger than the specified pore size; the pores are large and the flow rate is fast. Generally, the pore density of microporous membranes is 107 pores/cm2, and the micropore volume accounts for 70% to 80% of the total volume of the membrane. Because the membrane is very thin and has low resistance, its filtration speed is dozens of times faster than conventional filter media;
Microporous membranes are used for high-level purification of water, food and beverages Sterilization, filtration of medicinal liquids, air purification and sterilization in the fermentation industry, etc. The microporous membrane filters sugar solutions and alcoholic beverages such as beer and rice wine. It can remove impurities in sugar, yeast, mold and other microorganisms in alcoholic beverages, improve the purity of sugar and the clarity of alcoholic products, and extend the storage period. Since it is operated at room temperature, it will not change the taste of alcoholic products. And used in sterilization and particle removal of pharmaceuticals, etc.
The currently independently developed microporous sterilizing filter membrane has two categories: hydrophobic and hydrophilic. It is widely used in medicine, food, beverage, beer, chemical and other industries, such as filtration of sterile raw materials and liquid sterilization in the pharmaceutical industry, filtration of liquor, beverages, wine, fruit wine, etc. in the food industry, and organic solvents in the chemical industry. , various alcohols, chemical reagents, etc. filtration.
