Umzi-mveliso owaziwayo umgangatho ophezulu wePoly(1-vinylpyrrolidone-co-vinyl acetate)/VP/VA CAS:25086-89-9
Okokuqala nokuphambili, le copolymer ineempawu ezintle kakhulu zokwenza ifilimu.Iyakwazi ukwenza ifilimu ecacileyo ngokubambelela ngokugqwesileyo kunye nokuqina.Oku kwenza kube yinto efanelekileyo yokugqoka kunye ne-adhesives esetyenziswa kwiintlobo ezahlukeneyo zezicelo ezibandakanya iipende, i-varnishes kunye ne-varnishes.
Ukongeza, i-vinylpyrrolidone-vinyl acetate copolymers ibonisa ukunyibilika okugqwesileyo emanzini kunye neentlobo ezahlukeneyo ze-solvents eziphilayo.Oku kunyibilika kuvumela ukuba kusetyenziswe njenge-ejenti yokuqina kwiindlela ezahlukeneyo zokuqulunqa, kubandakanywa neemveliso zokhathalelo lomntu ezifana neegels zeenwele, izitshizi kunye nezithambiso.Iimpawu ezigqwesileyo zokubambelela kule copolymer nazo zenza ukuba ibe yinto ebalulekileyo ekwenzeni iipilisi kunye ne-capsules kwishishini lamachiza.
Ukongezelela, i-conductivity ye-vinylpyrrolidone-vinyl acetate copolymers inokuguqulwa ngokweemfuno ezithile, ibenze ifaneleke kwi-electronics kunye nezicelo zokugqoka.Ukuhambelana kwayo kunye neendawo ezahlukeneyo ezifana neentsimbi, iiplastiki kunye neempahla zongeza kwizinto ezininzi kunye nokusetyenziswa kwayo.
Ukongeza, ii-vinylpyrrolidone-vinyl acetate copolymers zizinzile ngokwe-thermal kwaye zixhathisa kwimitha ye-UV, ziqinisekisa ukuqina kunye nokusebenza ixesha elide kwizicelo zangaphandle.Oku kwenza kube lukhetho oluhle kakhulu lokukhusela kwizakhiwo, izithuthi kunye nezixhobo zombane.
Isishwankathelo, i-vinylpyrrolidone-vinyl acetate copolymers ineepropati ezintle kakhulu zokwenza ifilimu, i-solubility, conductivity yombane, kunye nokuzinza kwe-thermal, enikezela ngamathuba amaninzi kumashishini ahlukeneyo.Usetyenziso lwayo lususela kwiingubo kunye nokuncamathelisa kwiimveliso zokhathalelo lomntu kunye ne-elektroniki.Siqinisekile ukuba ii-vinylpyrrolidone-vinyl acetate copolymers zethu ziya kuhlangana kwaye zigqithise izinto ozilindeleyo ngomgangatho wazo ophezulu kunye nokusebenza okungaguqukiyo.
