The bubble point membrane is to take a PTFE bubble point membrane of a certain material, moisten it with a certain solution, and then pressurize one side to isolate the gas of a certain pressure. As the gas pressure increases, the gas flows from the PTFE bubble point membrane to the other side. Side release.
When the gas pressure is greater than the capillary pressure and surface tension in the membrane pores, the liquid can be forced out of the membrane pores.
If the type of membrane is different from the wetting fluid, that is to say, changes in membrane material, membrane structure, pore size, surface tension, and temperature will all affect the bubble point pressure.
Teflon foam film is prepared using unique biaxial stretching technology and has the characteristics of stable chemical properties, high filtration efficiency, easy cleaning, high temperature resistance, corrosion resistance and other characteristics.
