High strength of water-based polyvinylidene fluoride filter membrane

High strength water-based polyvinylidene fluoride filter membrane: It is prepared by using an automatic continuous membrane preparation machine to apply a casting solution composed of polyvinylidene fluoride resin, solvent, and pore forming additives on both sides of polyester non-woven fabric through phase transformation. The membrane has high mechanical strength, with a tensile strength (N/50mm) ranging from 250 in all directions and greater than 150 in the transverse direction.

　　High strength of water-based polyvinylidene fluoride filter membraneIt is prepared by using an automatic continuous film making machine to apply a casting solution composed of polyvinylidene fluoride resin, solvent, and pore forming additives on both sides of polyester non-woven fabric, and then undergoing phase transformation. The membrane has high mechanical strength, with a tensile strength (N/50mm) ranging from 250 in all directions and greater than 150 in the transverse direction. The membrane has good heat resistance and chemical stability. Can withstand high-pressure steam disinfection at 128-142 ℃, and can withstand strong acids, aliphatic, aromatic compounds, as well as various organic and inorganic solvents such as alcohols, aldehydes, ketones, ethers, etc. Due to the presence of polyester non-woven fabric, the film is not resistant to corrosion from caustic alkali, halides, and reinforcing acids. The membrane is fully covered on both sides, with no exposed fibers. The surface pores are densely distributed, and the pore shapes are circular and elliptical. The pore sizes on both sides are *, and the pore size distribution is narrow. The membrane has strong negative electrostatic and hydrophobic properties, making it a new type of precision filtration membrane that can be used for liquid sterilization, particle filtration, as well as gas dehumidification, sterilization, and dust removal filtration.

The specifications are as follows:
