Uma kukhulunywa ngama-polymers asezingeni eliphezulu, igama elilodwa liyagqama embonini - i-poly(1-vinylpyrrolidone-co-vinyl acetate).Le copolymer, ehlanganiswe ne-vinylpyrrolidone (VP) ne-vinyl acetate (VA) ngokusebenzisa i-polymerization yamahhala, ijabulela idumela eliphezulu ezimbonini ezihlukahlukene.Izakhiwo zayo ezinhle kakhulu ziyenza ibe isithako esibalulekile emikhiqizweni eminingi.Kule bhulogi, sizobhekisisa izici zale polymer ye-premium evela kumkhiqizi owaziwayo futhi sihlole ukuthi kungani idume kangaka.
Ukuhlukahluka kwe-poly (1-vinylpyrrolidone-vinyl acetate) ingenye yezinzuzo zayo ezibaluleke kakhulu.Ukwakheka kwayo kwamakhemikhali kuyivumela ukuthi ibonise ukuncibilika okuhle kakhulu emanzini nasezincibilikiseni eziphilayo.Lesi sakhiwo esiyingqayizivele siyenza ilungele ukusetshenziswa okuhlukahlukene okunamathelayo, okokunamathela, nezinhlelo zokulethwa kwezidakamizwa.Ikhono le-copolymer lokuncibilikisa kokubili izinto ezingama-hydrophilic kanye ne-lipophilic liyenza ibe inketho eguquguqukayo ezimbonini ezahlukahlukene.
Ngaphezu kokuguquguquka, i-copolymer inamakhono amahle kakhulu okwenza ifilimu.Uma isetshenziswa ezindaweni ezingaphezulu, yakha ifilimu efanayo, esobala, iyenze ibe ilungele ukumbozwa kanye nezingqimba zokuzivikela.I-poly yekhwalithi ephezulu (i-1-vinylpyrrolidone-vinyl acetate) iqinisekisa indawo ebushelelezi futhi ehlala isikhathi eside, ihlinzeka ngokuvikeleka kumswakama, ukushisa kanye nokuhuzuka.Lesi sakhiwo sikwenza kube isithako esibalulekile ekukhiqizeni amapende, oyinki kanye nezingubo zezimboni.
Enye yezinto eziphawuleka kakhulu zale polymer yekhwalithi ephezulu amandla ayo amahle kakhulu wokubopha.Ngenxa yesakhiwo sayo samangqamuzana, i-poly(1-vinylpyrrolidone-vinyl acetate) inokunamathela okuqinile ezindaweni ezihlukahlukene, okuhlanganisa ingilazi, insimbi, namapulasitiki.Lokhu kuyenza ibe isithako esibalulekile ekwakhekeni kwe-adhesive, glue kanye ne-tape.Amandla ayo ebhondi aphakeme nokumelana nomswakama kuqinisekisa izibopho ezihlala isikhathi eside ngisho nasezimweni eziyinselele.
I-Poly(1-vinylpyrrolidone-vinyl acetate) yaziwa ngokuzinza kwayo okuhle kakhulu nokuhambisana nezinye izinto.Izakhiwo zayo zokulwa ne-antioxidant, ukumelana nemisebe ye-UV kanye nokumelana nokuguquguquka kwezinga lokushisa kuyenza ilungele ukwakheka okuhlukahlukene.Kungakhathaliseki ukuthi isetshenziswa kwezemithi, izimonyo noma izinhlelo zokusebenza zezimboni, le copolymer inikeza ukuzinza nokuqina.Ukwengeza, ukuhambisana kwayo nezithasiselo ezihlukahlukene kanye nezithako ezisebenzayo kuthuthukisa ukusebenza nokusebenza komkhiqizo wokugcina.
Kafushane, i-poly yekhwalithi ephezulu (i-1-vinylpyrrolidone-co-vinyl acetate) ifakazele ukuthi iyi-polymer ebaluleke kakhulu ezimbonini ezingenakubalwa.I-solubility yayo enhle kakhulu, ikhono lokwenza ifilimu, izakhiwo zokunamathela, ukuzinza nokuhambisana kwenza kube ukukhetha kokuqala kwabakhiqizi nabakhiqizi.Kungakhathaliseki ukuthi ufuna isithako esishintshashintshashintshayo sokumboza, okokunamathelayo noma amasistimu okulethwa kwezidakamizwa, le copolymer iqinisekisa ukusebenza okungcono kakhulu kwekilasi.Themba le polymer eyingqayizivele ukuze uvule amandla eqiniso omkhiqizo wakho.
