| abstract | The present invention relates to a kind of viromembrane, viromembrane includes polysulfones 18～26%, polyvinylpyrrolidone 8～16%, glycerol 1～5%, NN dimethyl acetylamide 65～73%, further relate to the preparation method of viromembrane, NN dimethyl acetylamide, polysulfones are successively added to three-grade supply system and device stirring to dissolving, add polyvinylpyrrolidone stirring to dissolving, add glycerol stirring to dissolving, form preparation liquid, preparation liquid is delivered to diplopore spinneret film extrusion through three-grade supply system and device, purified water shapes, and forms viromembrane.The invention has the beneficial effects as follows: the surface of viromembrane forms the micropore of 0.01～0.02 μm, under natural hydraulic pressure, can have the removal of 99.99% to antibacterial, have the clearance of 99.99% equally to virus；And the water flux crossing drainage of viromembrane can reach 1800～2800ml/m 2 The capacity of outlet water of min 0.1MPa；Formula is simple, draws materials conveniently, and process is stable, production process less energy intensive, it is adaptable to large-scale industrial production. |
