POLYVINYL Alkòl
Pwodiktè: Sinopec
PVA gen anpil pwopriyete eksepsyonèl tankou solubility dlo, pwopriyete fibre-fòme, aderans, pwopriyete fim-fòme, estabilite EMULSION, estabilite dispèsyon, rezistans nan lwil oliv, asid, ak alkali, reaction chimik, byodegradabilite, osi byen ke meltability (oswa thermoplasticity) ak anpil pwopriyete inik ak espesyal nan modification.PVA lajman ki itilize nan endistri anpil tankou twal, du, konstriksyon, pwodwi chimik yo, enprime, anbalaj, edikaman, detèjan & pwodui kosmetik, agrikilti, seramik, fè & asye, elektwonik, electrolysis elektwoliz, ELECTROPLATING, ak elatriye
aplikasyon:
PVA, ki se ekselan nan pwoteksyon koloidal e li gen aktivite sifas siperyè, se souvan itilize kòm estabilizasyon dispèsyon pou sispansyon polymérisation klori vinil monome (VCM). ka pèfòmans nan nan PVC résine dwe anpil optimisé pa chwazi yon klas apwopriye PVA ak degre apwopriye nan polymérisation ak enzymatique.
EMULSION stabilizatris & Binder
PVA ka lajman itilize kòm koloidal pwoteksyon oswa epesiseur pou polymérisation nan EMULSION a vinil asetat (VAC) oswa VAC / ACRYLATE. gen karakteristik ki annapre yo: ekselan aderans; ogmante premye fofile epi mete yo seche to pandan y ap itilize ak filler; ekselan rezistans nan oiloutstanding fòs fim; andire ak pèfòmans ki estab.
fib fabwikasyon
De aplikasyon enpòtan nan PVA se yo dwe itilize kòm matières vinylon ak dimensionnement ajan pou textile.As materyèl anvan tout koreksyon nan vinylon fib, gen avantaj ki genyen nan ke yo te wo nan fòs, absòpsyon imidite, rezistans fwotman, rezistans limyè solèy la, rezistans korozyon ak blan nan koulè. Li kapab tou file ak koton, lenn mouton ak viscous fib oswa piman file ak itself.As dimensionnement ajan pou twal, Li pa pral rouye oswa deteryore ak yon Adhesion bon koton, chanvre, Polyester ak viscous fib.
Fim
PVA ka itilize yo pwodwi dlo idrosolubl fim ak fim dlo-rezistans. PVA a disponib nan fòme pwodwi ki mete aksan sou karakteristik yo ki nannan nan PVA, savwa, fòs segondè rupture, rezistans nan sòlvan òganik ak tightness.They lè yo tou de lajman ki itilize nan endistri a pake, pa sèlman pou twal, men tou pou pwodwi chimik, manje, pwodwi chimik chak jou, pwodwi chimik agrikòl, koloran, ak elatriye
Kaka & Papye
PVA te jwenn lajè itilize nan tretman an nan sifas papye kòm li gen aderans ekselan e dispersibility epi yo pa pral afekte pwopriyete a nan lòt atach yo itilize nan konbinezon. Avantaj ki genyen nan lè l sèvi avèk PVA: Sifas fòs (enprimabilite); fòs ansanm Z-aks (papye entèn fòs); rezistans Mari vlope; rezistans abraziv; Amelyore Harmony; Amelyore briyan sifas; leve soti vivan rezistans nan lwil oliv ak sòlvan (pwopriyete baryè).
