Warshada caanka ah ee tayada sare leh Poly(1-vinylpyrrolidone-co-vinyl acetate)/VP/VA CAS:25086-89-9
Ugu horrayn, kopolymer-kani waxa uu leeyahay sifooyin-samaynta filimada oo aad u fiican.Waxay samayn kartaa filim cad oo leh adhesion aad u fiican iyo adkeysi.Tani waxay ka dhigaysaa mid ku habboon dahaarka iyo dhejiska loo isticmaalo codsiyada kala duwan oo ay ku jiraan rinji, faashash iyo faashash.
Intaa waxaa dheer, vinylpyrrolidone-vinyl acetate copolymers waxay soo bandhigaan milmayn heer sare ah oo biyaha ah iyo noocyo kala duwan oo dareerayaasha organic.Solubility Tani waxay u ogolaaneysaa in loo isticmaalo sida wakiilka dhumucyada noocyo kala duwan, oo ay ku jiraan alaabta daryeelka shakhsi ahaaneed sida jellaha timaha, buufinta iyo loshinka.Qalabka xabagta ee ugu fiican ee copolymer-kan ayaa sidoo kale ka dhigaya qayb qiimo leh oo soo saarista kaniiniyada iyo kaabsoosha ee warshadaha dawooyinka.
Intaa waxaa dheer, conductivity of vinylpyrrolidone-vinyl acetate copolymers waa la bedeli karaa si waafaqsan shuruudaha gaarka ah, iyaga oo ku haboon codsiyada daahan elektarooniga ah.La jaanqaaditaankeeda substrate-ka kala duwan sida biraha, balaastikada iyo dunta ayaa ku kordhinaysa faa'iidada iyo waxtarkeeda.
Intaa waxaa dheer, vinylpyrrolidone-vinyl acetate copolymers waa kuleyl deggan oo adkaysi u leh shucaaca UV, hubinta adkeysiga iyo waxqabadka muddada dheer ee codsiyada dibadda.Tani waxay ka dhigaysaa doorasho aad u fiican oo loogu talagalay dahaarka ilaalinta ee dhismayaasha, baabuurta iyo qalabka elektaroonigga ah.
Marka la soo koobo, vinylpyrrolidone-vinyl acetate copolymers waxay leeyihiin sifooyin filim samaynta oo aad u fiican, milmayn, korantada korantada, iyo xasiloonida kulaylka, iyagoo siinaya fursado badan oo warshado kala duwan ah.Codsigeedu wuxuu u dhexeeyaa dahaarka iyo xabagta ilaa alaabta daryeelka shakhsi ahaaneed iyo elektiroonigga.Waxaan kalsooni ku qabnaa in copolymersyadayada vinylpyrrolidone-vinyl acetate copolymers ay la kulmi doonaan oo ay dhaafi doonaan waxyaabaha aad ka filayso tayada sare iyo waxqabadkooda joogtada ah.
