polymeric membrane for separation
Polymeric membrane for separation is a membrane made of polymer or polymer composite material with the function of separating fluid mixture. Membrane separation is based on the selective permeability of the membrane. The separation membrane is used as the spacer layer. Under the driving force of pressure difference, concentration difference, or potential difference, the components in the fluid mixture penetrate the membrane at different rates to make it Both sides are enriched separately to achieve the purpose of separation, purification, concentration and recycling. The amount of fluid passing through the membrane per unit time (permeation rate), the ratio of the permeability coefficient of different substances (separation coefficient), or the rejection rate of a certain substance are important indicators for measuring the performance of the membrane.
