I-Polyvinyl alcohol CAS:25213-24-5

I-Polyvinyl alcohol (PVA) isetshenziswa kakhulu ezimbonini ezahlukahlukene ngenxa yezakhiwo zayo eziphawulekayo. Embonini yokunamathela, isebenza njengesithako esiyinhloko ekwakhiweni okuhlukahlukene, inikeza izakhiwo eziqinile zokubopha ekusetshenzisweni kusukela ekunamathiseleni kokhuni kuya ekunamathiseleni kwephepha. Ukuncibilika kwayo emanzini kanye namakhono okwenza ifilimu kuyenza ibe yinto ebalulekile ekukhiqizweni kwezinto zokupakisha ezincibilika emanzini, izikhwama zokugeza, kanye nezinto zokulinganisa izindwangu, inikeza izixazululo zezidingo zokupakisha ezinobungani nemvelo nezincibilikayo. Embonini yezindwangu, i-PVA isetshenziswa kabanzi njenge-ejenti yokulinganisa i-warp ukuthuthukisa inqubo yokweluka, inikeze amandla kanye nokuguquguquka kwezintambo. Ngaphezu kwalokho, isebenza njenge-colloid evikelayo ekukhiqizweni kwama-copolymer asekelwe ku-vinyl acetate kanye ne-binder ekunyatheliseni i-pigment. Ngaphezu kwalokho, i-PVA idlala indima ebalulekile embonini yephepha, lapho isetshenziswa khona njenge-ejenti yokulinganisa ubuso ukuthuthukisa amandla ephepha, ukuphrinta, kanye nokumuncwa kweyinki. Izimboni zemithi nezokudla zisebenzisa i-PVA ekukhiqizweni kwama-capsule, njenge-ejenti yokumboza amaphilisi, kanye nasekudalweni kwamafilimu adliwayo okupakisha ukudla. Ukuhambisana kwayo nezinto eziphilayo kanye nokungabi nobuthi nakho kwenza i-PVA ibe yinto ebalulekile ekusetshenzisweni kwezokwelapha, okuhlanganisa njengengxenye yokubopha amanxeba, izinhlelo zokulethwa kwemithi, kanye nezisekelo zobunjiniyela bezicubu. Sekukonke, ukusetshenziswa okuhlukahlukene kwe-PVA kugqamisa ukubaluleka kwayo njenge-polymer eguquguqukayo emikhakheni ehlukahlukene yezimboni neyezentengiselwano.
