Imboni edumile yekhwalithi ephezulu yePoly(1-vinylpyrrolidone-co-vinyl acetate)/VP/VA CAS:25086-89-9
Okokuqala nokubaluleke kakhulu, le copolymer inezakhiwo ezinhle kakhulu zokwenza ifilimu.Ingenza ifilimu ecacile ngokunamathela okuhle kakhulu nokuqina.Lokhu kuyenza ilungele ukumbozwa kanye nezinamatheliso ezisetshenziswa ezinhlobonhlobo zezicelo ezihlanganisa amapende, ama-varnishes nama-varnish.
Ngaphezu kwalokho, i-vinylpyrrolidone-vinyl acetate copolymers ikhombisa ukuncibilika okuhle kakhulu emanzini kanye nezinhlobonhlobo zezinyibilikisi eziphilayo.Lokhu kuncibilika kuvumela ukuthi kusetshenziswe njenge-ejenti yokuqina ekwakhiweni okuhlukahlukene, okubandakanya imikhiqizo yokunakekelwa komuntu siqu njengama-gel ezinwele, izifutho kanye nama-lotions.Izakhiwo ezinhle kakhulu zokunamathisela zale copolymer zenza futhi isithako esibalulekile ekwenzeni amaphilisi namaphilisi embonini yezemithi.
Ngaphezu kwalokho, i-conductivity ye-vinylpyrrolidone-vinyl acetate copolymers ingashintshwa ngokuvumelana nezidingo ezithile, ibenze ifaneleke ku-electronics kanye nezicelo zokugqoka eziqhutshwayo.Ukuhambisana kwayo nama-substrates ahlukahlukene njengezinsimbi, amapulasitiki nezindwangu kwengeza ekusebenzeni kwayo okuhlukahlukene kanye nokusebenziseka kwayo.
Ukwengeza, ama-vinylpyrrolidone-vinyl acetate copolymers azinzile ngokushisa futhi amelana nemisebe ye-UV, aqinisekisa ukuqina nokusebenza okuhlala isikhathi eside kwezinhlelo zokusebenza zangaphandle.Lokhu kukwenza kube ukukhetha okuhle kakhulu kwezingubo zokuvikela ezakhiweni, ezimotweni nasezintweni zikagesi.
Kafushane, i-vinylpyrrolidone-vinyl acetate copolymers inezakhiwo ezinhle kakhulu zokwenza ifilimu, i-solubility, conductivity kagesi, kanye nokuzinza kwe-thermal, enikeza amathuba amaningi ezimboni ezahlukene.Izicelo zayo zisukela ezimbotsheni nezinamatheliso kuye emikhiqizweni yokunakekelwa komuntu siqu kanye nezinto zikagesi.Siyaqiniseka ukuthi ama-copolymers ethu e-vinylpyrrolidone-vinyl acetate azohlangabezana futhi adlule okulindele ngekhwalithi yawo ephezulu nokusebenza okungaguquki.
