| titleOfInvention | Polyvinyl chloride hollow fiber composite nanometer filtering film and preparation method thereof |
| abstract | The present invention provides a kind of polyvinyl chloride hollow fiber composite nanometer filtering film, including basement membrane and the ultra-thin separating layer formed in membrane surface；Basement membrane is polyvinyl chloride hollow fiber microporous barrier；Ultra-thin separating layer is aramid layer；Preparation method includes: a step, and deionized water rinses basement membrane component, and air purges basement membrane inner surface, the first polynary amine aqueous solution introduces basement membrane inner cavity, and air purges film wire inner surface after amination；Two steps, more than second yuan of amine aqueous solution introduce basement membrane inner cavity, slightly drain rear air purging film wire inner surface；Three steps, polynary solution of acid chloride introducing are further processed membrane module, two steps processing membrane module or a step and two steps processing membrane module film inner cavity, hang in air after reaction；Four steps, deionized water rinse the membrane module through using polyamine as aqueous phase monomers, polynary acyl chlorides being the polymerization processing of organic phase monomer interface, the electropositive polyvinyl chloride hollow fiber composite nanometer filtering film of lotus must be presented；To plumbi nitras in water, magnesium sulfate, magnesium chloride, calcium chloride rejection up to 95% or more. |
