VP / VA Copolymers
I-VP / VA Copolymers ivelisa iifilimu ezingafihliyo, eziguquguqukayo, ezivumela ioksijini ukuba zikwazi ukubambelela kwiglasi, iiplastiki kunye nesinyithi.I-Vinylpyrrolidone / i-acetate ye-Vinyl (i-VP / VA) i-resins i-linear, i-copolymers engahleliwe eveliswa yi-polymerization yamahhala ye-monomers kwii-diferrent ratios.VP / VA Copolymers zifumaneka njenge powders ezimhlophe okanye izisombululo ezicacileyo kwi-ethanol namanzi.Ii-copolymers ze-VP / VA zisetyenziswa ngokubanzi njengabadlali befilimu ngenxa yokuguquguquka kwefilimu, ukubambelela kakuhle, ukukhazimula, ukubuyisela amanzi kunye nobunzima.Ezi zakhiwo zenza i-PVP / VA copolymers ezifanelekileyo kwiindidi ezahlukeneyo zoshishino, ukunakekelwa komntu kunye neemveliso zamachiza.
