Emulsion Stabilizer & Binder
PVA ka lajman itilize kòm koloyid pwoteksyon oswa epesè pou polymérisation emulsyon nan acetate vinil (VAc) oswa VAc / acrylate.gen karakteristik sa yo: ekselan 0adhesiveness; ogmante inisyal tack ak to siye pandan w ap itilize ak filler;ekselan rezistans nan lwil oliv;fim eksepsyonèl.
Nan fabrikasyon fib
De aplikasyon enpòtan nan PVA yo dwe itilize kòm materyèl vinylon ak ajan dimensionnement pou twal. Kòm matyè premyè nan fib vinylon, gen avantaj ki genyen nan yo te wo nan fòs, absòpsyon imidite, rezistans abrasion, rezistans limyè solèy la, rezistans korozyon ak koulè blan.Li kapab tou file ak koton, lenn mouton ak fib viskoz oswa piman file ak tèt li. Kòm ajan dimensionnement pou twal, Li pa pral korode oswa deteryore ak yon adezyon bon nan koton, chanv, Polyester ak fib viskoz.
Pulp & PaperPVA te jwenn itilizasyon lajè nan tretman sifas papye paske li gen ekselan adezif ak dispersibilite epi li pa pral afekte pwopriyete lòt lyan yo itilize nan konbinezon.Avantaj ki genyen nan PVA lè l sèvi avèk: Fòs sifas (enprimabilite)；Fòs sou aks Z (fòs entèn papye);Rezistans plisman；Rezistans abrazif;Amelyore lis; Amelyore glossiness sifas;Ogmante rezistans nan lwil oliv ak sòlvan (pwopriyete baryè).
Fim
PVA ka itilize yo pwodwi fim dlo idrosolubl ak fim rezistans dlo.PVA ki disponib nan pwodwi ki fòme ki mete aksan sou karakteristik yo nannan nan PVA, sètadi, gwo fòs rupture, rezistans nan sòlvan òganik ak sere lè. Yo tou de lajman itilize nan la. endistri pake, pa sèlman pou twal, men tou pou pwodwi chimik, manje, pwodwi chimik chak jou, pwodwi chimik agrikòl, koloran, ak elatriye.
Dispèsyon Stabilizer
PVA, ki se ekselan nan pwoteksyon koloyid e ki gen aktivite siperyè sifas, yo souvan itilize kòm estabilize dispèsyon pou sispansyon polymerization nan monomère klori vinil (VCM).Pèfòmans PVC résine ka anpil optimisé pa chwazi yon klas PVA apwopriye ak bon degre polymérisation ak hydrolyse.
Nou gen plis pase 1000m2 depo pou PVA asire w ke rezèv la ki estab ak pri konpetitif toujou.
