| titleOfInvention | A kind of polymer ultrafiltration membrane |
| abstract | A kind of polymer ultrafiltration membrane, it is characterised in that specific preparation method is as follows：Under normal temperature, ethyl cellulose is added to uniform stirring among N methyl pyrrolidone solvents, high polymer material is completely dissolved formation basement membrane liquid in a solvent；The dispersant of polyvinylpyrrolidone pore-foaming agent and polyethylene glycol and Tissuemat E is added in obtained basement membrane liquid, mixed liquor is heated to 65 DEG C for 3500w microwave heating equipment using power, then the scattered 30min of concussion is carried out using supersonic generator, filtering deaeration processing is carried out after being uniformly dispersed and forms casting solution, by obtained coating liquid blade coating on polyester non-woven fabric, in atmosphere after placement a period of time, in the coagulation bath for being immersed in 75 DEG C, pass through gel solidification film forming, obtained filter membrane is put into 60 DEG C of distilled water and washed, taken out after 2 hours, dried in 32 DEG C of drying room, production process of the present invention is simple, it is easy to operate, production cost is low, it is easy to industrialized production, application is more extensive. |
