Imiterere ifatika n'imirimo y'ingenzi y'ibikoresho byo gutunganya PVC

Ubufasha mu gutunganya PVC ni polymer ya thermoplastic graft ikomoka kuri polymerization ya methyl methacrylate na acrylate binyuze mu lotion y'imbuto. Ikoreshwa cyane cyane mu gutunganya no gukora ibikoresho bya PVC. Igira ingaruka nziza mu kunoza ubudahangarwa bw'ibikoresho bya PVC. Ishobora gutegura uburyo bwa polymerization bw'intambwe nyinshi ikoresheje polymerization y'imbuto, harimo polymerization ya lotion gakondo na polymerization y'inkingi y'ibumba. Akamaro kayo kari mu bushobozi bwo kugenzura imiterere, ingano, ubugari bw'igikonoshwa, ikigereranyo cy'igikonoshwa n'umurongo w'imbere, imiterere y'imikorere y'ubuso, n'ibindi by'uduce duto bitewe n'ibikenewe bitandukanye mu gihe cyo gukora synthesis reaction, kandi ingano y'uduce duto ikwirakwira neza.

Ibikoresho by'ingenzi bikoreshwa mu gutunganya PVC ni esters za acrylic na methacrylate ya methyl. Mu ikorwa nyaryo, acrylate ibanza guhindurwamo polymer hamwe n'izindi monomers (nka styrene, acrylonitrile, nibindi) binyuze mu mavuta kugira ngo hakorwe polymer ifite ubushyuhe buke bwo guhindura ikirahure, ni ukuvuga core ifite imiterere ya elastomer, hanyuma ikarangizwa na methyl methacrylate, styrene, nibindi kugira ngo hakorwe polymer ifite imiterere y'igishishwa cy'ibanze. Ingano ikomeye y'iyi lotion ikarangizwamo polymer muri rusange ni hafi 45% ± 3%, kandi lotion yumishwa ikabura amazi kugira ngo amazi y'ibicuruzwa abe munsi ya 1% (igice cy'ubunini) kugira ngo haboneke ifu yera.

Polymerization y'igishishwa cy'ibanze ni ingenzi mu ikoranabuhanga ryo gukora resin ya ACR. Imiterere y'igishishwa cy'ibanze cya ACR ishobora kugabanywamo ubwoko butatu: imiterere y'igishishwa cy'ibanze cyoroshye, imiterere y'igishishwa cy'ibanze cyoroshye, n'imiterere y'urwego rutatu rworoshye rworoshye. Ariko, ubwoko bw'ingenzi bugurishwa ku isoko ubu ni "imiterere y'igishishwa cy'ibanze cyoroshye". Resin za ACR zifite iyi miterere zifite imikorere myiza kandi zikoreshwa cyane. Polymerization y'igishishwa cy'ibanze cya "imiterere y'igishishwa cy'ibanze cyoroshye" ni inzira aho monomer ikomeye iterwa ku mbuto z'uduce twa latex tworoshye twakozwe n'intambwe ya mbere ya polymerization ya lotion. Ubwoko n'ingano ya emulsifiers, ikigereranyo cy'igishishwa cy'ibanze, uburyo bwo kugaburira monomer y'igishishwa, urwego rwo guhuza uduce twa latex y'imbuto (umukara), ingano y'uduce tw'imbuto, n'ubwoko n'ingano y'ikintu gihuza byose bigira ingaruka zikomeye ku miterere y'igishishwa cy'igice cya latex cya ACR n'imikorere ya nyuma ya ACR.
