Uruganda ruzwi cyane Poly (1-vinylpyrrolidone-co-vinyl acetate) / VP / VA CAS: 25086-89-9
Mbere na mbere, iyi copolymer ifite ibintu byiza byo gukora firime.Irashobora gukora firime isobanutse neza kandi ihamye.Ibi bituma biba byiza kubitwikiriye hamwe nibisumizi bikoreshwa muburyo butandukanye burimo amarangi, amarangi na langi.
Byongeye kandi, vinylpyrrolidone-vinyl acetate copolymers yerekana imbaraga zidasanzwe mumazi hamwe nudukoko twinshi kama.Uku kwikemurira kwemerera gukoreshwa nkigikoresho cyo kubyimba muburyo butandukanye, harimo ibicuruzwa byita kumuntu nka geles yimisatsi, spray hamwe namavuta yo kwisiga.Ibintu byiza bifata neza byiyi copolymer nabyo bituma iba ingirakamaro mugukora ibinini na capsules mu nganda zimiti.
Byongeye kandi, imiyoboro ya vinylpyrrolidone-vinyl acetate copolymers irashobora guhindurwa ukurikije ibisabwa byihariye, bigatuma ikoreshwa rya elegitoroniki hamwe nogukoresha ibikoresho.Guhuza kwayo nubutaka butandukanye nkibyuma, plastike n imyenda byiyongera kubikorwa byinshi kandi byingirakamaro.
Byongeye kandi, vinylpyrrolidone-vinyl acetate copolymers ihagaze neza kandi irwanya imirasire ya UV, itanga igihe kirekire kandi ikora igihe kirekire kubikorwa byo hanze.Ibi bituma uhitamo neza kubirinda inyubako, ibinyabiziga nibikoresho bya elegitoroniki.
Muri make, vinylpyrrolidone-vinyl acetate copolymers ifite imiterere myiza yo gukora firime, gukemura, amashanyarazi, hamwe nubushyuhe bwumuriro, bitanga amahirwe menshi mubikorwa bitandukanye.Porogaramu zayo zirimo ibifuniko hamwe nibisumizi kugeza kubicuruzwa byawe bwite hamwe na elegitoroniki.Twizeye ko vinylpyrrolidone-vinyl acetate copolymers izahura kandi irenze ibyo wari witeze hamwe nubwiza bwabo buhebuje kandi buhoraho.
