Microfiltration and ultrafiltration membranes prepared by stretching, phase inversion, etc. have pores that penetrate the membrane body, thereby forming a porous membrane.
The mechanism of the porous membrane process can be explained by sieving theory. Particles with a particle size smaller than the membrane pores can pass through the membrane pores, particles with a particle size equal to the membrane pores can block the membrane pores, and particles larger than the membrane pores are intercepted by the membrane body.
In addition, the adsorption and interception of charged particles on the membrane surface and membrane pores, and the bridging and interception of particles smaller than the pore size at the pore openings also have a certain interception effect.
PTFE film manufacturer specializes in the production of PTFE porous membranes. It has a full set of advanced production equipment and technology. It also has an advanced clean room and an independent composite slitting workshop to ensure the production quality of PTFE membranes.
