| titleOfInvention | A kind of PVDF tubular ultra-filtration membrane and its preparation method and application |
| abstract | The present invention relates to filtering technical field of membrane, in particular to a kind of PVDF tubular ultra-filtration membranes and its preparation method and application.PVDF tubular ultra-filtration membrane includes the film layer of micropore support tube and the adherency of its inner surface；By weight, micropore support tube is mainly made of following material: 80 parts of high density polyethylene (HDPE), 1-3 parts of titanium dioxide, 1-3 parts of talcum powder；Film layer is mainly made of following material: 70-80 parts of polyvinylidene fluoride resin, 10-20 parts of polymethyl methacrylate, 4-7 parts of polyethylene glycol, 5-10 parts of chitosan, 2-4 parts of polyvinyl alcohol, and 1-3 parts of polyvinylpyrrolidone.The PVDF tubular ultra-filtration membrane film layer is embedded between micropore support tube, and formed firm anchor formula link, film layer is difficult to remove from support frame, and finally obtained PVDF tubular ultra-filtration membrane water flux is substantially improved, in 1100L/m 2 Hbar25 DEG C or more, and service life overlength. |
