Filtration is a commonly used technology in laboratories. Membrane filtration is the most effective and easy-to-operate filtration method. Today I will introduce to you a kind of membrane, which is PTFE liquid filtration membrane.
Liquid separation membrane refers to a membrane that can separate substances in liquid-liquid or liquid-solid states.
Microfiltration membranes or ultrafiltration membranes are mainly used to separate suspensions; ultrafiltration membranes or reverse osmosis membranes are mainly used to separate emulsions; in aqueous solutions, ultrafiltration membranes are mainly used to separate solutes with a molecular weight of more than 1000; and to separate water For true solutions, such as salts, reverse osmosis membranes must be used.
The separation of organic solutions with different boiling points, especially the separation of azeotropic mixtures, is the main application of liquid separation membranes, such as the separation of ethanol from water-ethanol systems.
The principle is to use the differences in dissolution and diffusion of substances in a liquid film to separate them.
At present, water pollution in our country is becoming increasingly serious, which makes people pay more attention to the issue of drinking water.
Filtration membrane removes impurities from water through extremely small membrane pores and has many advantages in drinking water treatment.
The PTFE liquid filtration membrane prepared by a special process has a microporous structure with staggered fibers. It has high porosity and small and uniform pore diameter.
PTFE filter membrane can achieve higher efficiency with lower resistance.
Suzhou New Material Technology Co., Ltd. is a high-tech enterprise specializing in the research, development and production of fluorine material membrane technology. The ptfe liquid filtration membrane we made by mechanically stretching ptfe material not only has excellent chemical stability and thermal stability , electrical insulation, and also has excellent waterproof, windproof, moisture-permeable, breathable and stable charge storage properties.
It is a new membrane material with great application prospects in many fields.
