The materials of microfiltration membranes are divided into two categories: organic and inorganic. Organic polymers include cellulose acetate, polypropylene, polycarbonate, polyethersulfone, polyamide, etc. Inorganic membrane materials include ceramics and metals. In view of the separation characteristics of microporous filter membranes, the application scope of microporous filter membranes is mainly to intercept particles, bacteria and other pollutants from the gas phase and liquid phase to achieve the purpose of purification, separation and concentration.
For microfiltration, the retention characteristics of the membrane are characterized by the pore size of the membrane, which usually ranges from 0.1 to 1 Micron, so the microfiltration membrane can separate large-diameter bacteria, suspended solids, etc. Teflon bubble membrane is a microfiltration membrane. Microfiltration membrane can be used for clarification, security filtration, and air sterilization filtration of general liquid materials. Currently, there are the following types of filter membranes on the market suitable for filtration of organic solvents:
1. Polytetrafluoroethylene membrane (PTFE) filter element
It is divided into hydrophilic PTFE membrane and hydrophobic PTFE membrane; it has absolute precision and wide chemical compatibility; it is suitable for gas sterilization filtration, filtration of various acids, alkalis, and organic solvents
2. Polyvinylidene fluoride membrane (PVDF) filter element
It is divided into hydrophilic PVDF membrane and Hydrophobic PVDF membrane; has absolute precision and wide chemical compatibility; suitable for gas sterilization filtration, filtration of various acids, alkalis, and organic solvents
3. Nylon membrane (N6N66) filter element
It is divided into two membranes, N6 and N66; with absolute precision; suitable for filtration of organic solvents and liquid sterilization filtration
The currently independently developed Teflon bubble point membrane series is widely used in organic solvent filtration and has two categories: hydrophobic and hydrophilic. . Teflon bubble point membrane used for gas filtration can achieve sterility, has large flux, high temperature resistance, resistance to strong acid and alkali, wide chemical applicability, etc. It is suitable for fermentation tanks, carbon dioxide, and nitrogen. and compressed air. When used for liquid filtration, it can 100% intercept various phages, bacteria and particles above 0.2μm, meeting the requirements of HIMA bacterial interception experiments.
