Research Progress Of PVDF Membrane

Research Progress Of PVDF Membrane


System to summary has poly partial fluoride vinyl film structure and performance of effect factors. different of additives on film structure of effect also different. General and on the, low boiling point additives of joined makes film of support layer has sponge-like hole structure; and inorganic salts, and water-soluble polymer of joined, will makes solvent and precipitation agent of exchange rate speed up, makes film of support layer has refers to-like hole structure. precipitation agent of solidification strength more high, and solvent and precipitation agent of affinity more strong, more easy formed refers to-like hole structure of film. through on poly partial fluoride vinyl film of modified sex, You can improve the practical performance.
