Feme e tsebahalang ea boleng bo holimo Poly(1-vinylpyrrolidone-co-vinyl acetate)/VP/VA CAS:25086-89-9
Ntlha ea pele, copolymer ena e na le thepa e babatsehang ea ho etsa lifilimi.E ka etsa filimi e hlakileng e nang le ho khomarela hantle le ho tšoarella.Sena se etsa hore e be se loketseng bakeng sa ho roala le likhomaretsi tse sebelisoang lits'ebetsong tse fapaneng tse kenyelletsang lipente, li-varnish le li-varnish.
Ntle le moo, li-copolymers tsa vinylpyrrolidone-vinyl acetate li bonts'a ho qhibiliha ha metsi ka bongata le mefuta e fapaneng ea li-solvents.Solubility ena e lumella hore e sebelisoe e le ntho e teteaneng ka mefuta e sa tšoaneng, ho kenyelletsa le lihlahisoa tsa tlhokomelo ea botho tse kang li-gel tsa moriri, li-sprays le lotions.Lintho tse babatsehang tsa ho khomarela tsa copolymer ena li boetse li etsa hore e be motsoako oa bohlokoa ha ho etsoa matlapa le li-capsules bakeng sa indasteri ea meriana.
Ho phaella moo, conductivity ea vinylpyrrolidone-vinyl acetate copolymers e ka fetoloa ho ea ka litlhoko tse khethehileng, e etsa hore e tšoanelehe bakeng sa lisebelisoa tsa elektronike le lisebelisoa tsa ho roala.Ho tsamaellana ha eona le li-substrates tse fapaneng tse kang tšepe, lipolasetiki le masela ho eketsa bokhoni ba eona le ts'ebeliso ea eona.
Ho feta moo, li-copolymers tsa vinylpyrrolidone-vinyl acetate li tsitsitse ka mocheso ebile li hanyetsa mahlaseli a UV, li netefatsa ho tšoarella le ts'ebetso e tšoarellang bakeng sa lits'ebetso tsa kantle.Sena se etsa hore e be khetho e babatsehang bakeng sa liphahlo tse sireletsang mehahong, likoloing le lisebelisoa tsa elektroniki.
Ka kakaretso, li-copolymers tsa vinylpyrrolidone-vinyl acetate li na le thepa e ntle ea ho etsa lifilimi, ho qhibiliha, ho tsamaisa motlakase, le botsitso ba mocheso, ho fana ka menyetla e mengata bakeng sa liindasteri tse fapaneng.Lisebelisoa tsa eona li tloha ho lira le likhomaretsi ho lihlahisoa tsa tlhokomelo ea motho le lisebelisoa tsa elektroniki.Re kholisehile hore li-copolymers tsa rona tsa vinylpyrrolidone-vinyl acetate li tla kopana le ho feta litebello tsa hau ka boleng ba tsona bo phahameng le ts'ebetso e tsitsitseng.
