Emulsion Stabilizer & Binder
PVA angagwiritsidwe ntchito monga zoteteza colloid kapena thickener kwa emulsion polymerization wa vinilu acetate (VAc) kapena VAc / acrylate.ali ndi izi: kumamatira kwabwino 0;kuchuluka koyambira koyambira ndi kuyanika pomwe kumagwiritsidwa ntchito ndi filler;kukana kwambiri mafuta;filimu yabwino kwambiri.
Mu kupanga fiber
Ntchito ziwiri zofunika za PVA ziyenera kugwiritsidwa ntchito ngati vinylon feedstock ndi sizing agent for textile.Monga zopangira za vinylon fiber, zili ndi maubwino okhala ndi mphamvu zambiri, kuyamwa kwa chinyezi, kukana abrasion, kukana kuwala kwa dzuwa, kukana dzimbiri ndi mtundu woyera.Ithanso kulukuta ndi thonje, ubweya ndi viscose ulusi kapena kudzipota yokha yokha. Monga chopangira nsalu, Sizingawononge kapena kunyonyotsoka ndikumatira bwino ku thonje, hemp, poliyesitala ndi viscose fiber.
Pulp & PaperPVA yapeza kuti imagwiritsidwa ntchito kwambiri pochiza mapepala apamwamba chifukwa imakhala ndi zomatira komanso zowoneka bwino ndipo sizikhudza katundu wa zomangira zina zomwe zimagwiritsidwa ntchito kuphatikiza.Ubwino wa PVA ntchito: pamwamba mphamvu (printability); Mphamvu pamodzi Z-olamulira (pepala mkati mphamvu); Pitirizani kukana; abrasive kukana; kusalala bwino; Kuwala pamwamba glossiness; Anakweza kukana mafuta ndi zosungunulira (chotchinga katundu).
Kanema
PVA ingagwiritsidwe ntchito kupanga filimu yosungunuka m'madzi ndi filimu yosasunthika ndi madzi.PVA imapezeka muzinthu zopangidwa zomwe zimasonyeza zachibadwa za PVA, zomwe ndi mphamvu zamakokedwe, kukana zosungunulira za organic ndi kupuma kwa mpweya. mafakitale a phukusi, osati zovala zokha, komanso mankhwala, chakudya, mankhwala tsiku lililonse, mankhwala aulimi, utoto, ndi etc.
Dispersion Stabilizer
PVA, yomwe ndi yabwino kwambiri poteteza colloid ndipo imakhala ndi ntchito zapamwamba kwambiri, imagwiritsidwa ntchito ngati dispersion stabilizer pakuyimitsidwa kwa polymerization ya vinyl chloride monomer (VCM).Ntchito ya PVC utomoni akhoza kwambiri wokometsedwa ndi kusankha yoyenera PVA kalasi ndi digiri yoyenera polymerization ndi hydrolysis.
Tili ndi malo osungiramo zinthu opitilira 1000m2 a PVA kuti tiwonetsetse kuti kupezeka kokhazikika komanso mtengo wopikisana nthawi zonse.
