Iyo bigeze kuri polymers yo mu rwego rwo hejuru, izina rimwe rigaragara mu nganda - poly (1-vinylpyrrolidone-co-vinyl acetate).Iyi copolymer, igizwe na vinylpyrrolidone (VP) na vinyl acetate (VA) binyuze muri polymerisiyumu yubusa, ifite izina ryinshi mubikorwa bitandukanye.Imiterere yacyo nziza ituma iba ingenzi mubicuruzwa byinshi.Muri iyi blog, tuzareba neza imiterere yiyi polymer polymer duhereye ku ruganda ruzwi kandi tumenye impamvu ikunzwe cyane.
Ubwinshi bwa poly (1-vinylpyrrolidone-vinyl acetate) ni kimwe mu byiza byingenzi byingenzi.Ibigize imiti ituma bigaragaza imbaraga zidasanzwe mumazi no mumashanyarazi.Uyu mutungo udasanzwe utuma biba byiza mubikorwa bitandukanye nka adhesives, coatings, hamwe na sisitemu yo gutanga ibiyobyabwenge.Ubushobozi bwa copolymer bwo gushonga ibintu byombi bya hydrophilique na lipofilique bituma ihitamo byinshi mubikorwa bitandukanye.
Usibye guhinduka, copolymer ifite ubushobozi bwiza bwo gukora film.Iyo ushyizwe hejuru, ikora firime imwe, ibonerana, ikora neza kubitwikiriye no kurinda.Poli yo mu rwego rwohejuru (1-vinylpyrrolidone-vinyl acetate) itanga ubuso bunoze kandi burambye, butanga uburinzi bwubushuhe, ubushyuhe nubushuhe.Uyu mutungo ubigize ikintu cyingenzi mugukora amarangi, wino hamwe ninganda.
Imwe mu miterere igaragara yiyi polymer yo mu rwego rwo hejuru nubushobozi bwayo bwiza bwo guhuza.Bitewe n'imiterere ya molekile, poly (1-vinylpyrrolidone-vinyl acetate) ifata cyane ku bice bitandukanye, birimo ibirahuri, ibyuma, na plastiki.Ibi bituma iba ikintu cyingenzi muburyo bwo gufatira hamwe, kole na kaseti.Imbaraga zayo zisumba izindi hamwe no kurwanya ubushuhe byemeza isano rirambye ndetse no mubidukikije bigoye.
Poly (1-vinylpyrrolidone-vinyl acetate) izwiho guhagarara neza no guhuza nibindi bikoresho.Imiterere ya antioxydeant, kurwanya imirasire ya UV no kurwanya ihindagurika ryubushyuhe bituma biba byiza muburyo butandukanye.Byaba bikoreshwa muri farumasi, kwisiga cyangwa gukoresha inganda, iyi copolymer itanga ituze kandi iramba.Byongeye kandi, guhuza kwayo ninyongeramusaruro zitandukanye nibikoresho bikora byongera imikorere nubushobozi bwibicuruzwa byanyuma.
Muri make, poli yo mu rwego rwo hejuru (1-vinylpyrrolidone-co-vinyl acetate) yerekanye ko ari polymer ntagereranywa mu nganda zitabarika.Ubwiza buhebuje, ubushobozi bwo gukora firime, imiterere ifatika, ituze hamwe nubwuzuzanye bituma ihitamo ryambere ryabakora nababikora.Waba ushaka ibintu byinshi bitandukanye byo gutwikira, gufatira hamwe cyangwa uburyo bwo gutanga ibiyobyabwenge, iyi copolymer yemeza imikorere myiza-mu ishuri.Wizere iyi polymer idasanzwe kugirango ufungure ibicuruzwa byawe byukuri.
