In recent years, with the development of biomaterials, microporous filter membranes have gradually replaced or improved many traditional filtration processes in their application process, becoming a modern industrial Especially in high-tech and precision industries, such as electronics, biopharmaceuticals, scientific research and quality testing, it is an indispensable and important means to ensure product quality.
Microfiltration can intercept particles larger than 0.1-1 micron. The microfiltration membrane allows macromolecules and dissolved solids (inorganic salts) to pass through, but it retains suspended solids, large molecular weight colloids and other substances. The operating pressure of microfiltration membrane is generally 0.7-7bar.
Microfiltration is often used to clarify the original solution in biomedical technology (such as intracellular soluble proteins expressed by E. coli, and the broken solution often needs to be Microfiltration clarification, and then proceed to the next step) and processing (such as VLPs and monoclonal antibodies usually need to be filtered with a 0.22um filter membrane for sterile processing).
General microfiltration products are mainly made of filter elements of various materials, and there are also laminated filter elements for deep filtration. Currently, laminated filter elements are the main development trend, and laminated filter elements are also It is called a membrane stack. The mainstream ones have 7 to 20 layers. They can have consistent membrane pore sizes or different pore sizes in different layers. Stacked microfiltration membranes have good results for deep filtration and raw solution clarification.
The currently independently developed PTFE bubble point film series is widely used in food and beverage, medicine and health, electronics, chemical industry, environmental monitoring and other fields, with a 0.1μm , various pore size specifications of 0.45μm, 1μm and 0.22um filter membrane are generally praised by customers!
0.22um filtration membrane technology has always been the core of the business, in biopharmaceuticals, equipment, food and beverages, semiconductor processes, and communications It plays a very important role in many fields, with pore-forming capacity ranging from 0.1μm to 1μm, providing functional solutions such as fine filtration, removal of small bacteria and viruses, hydrophobic breathability, and sound transmission.
