Emulsion Stabilizer & Binder
PVA waxaa si weyn loogu isticmaali karaa kolloid-ilaaliye ama dhumuc si loo polymerization emulsion of vinyl acetate (Vac) ama Vac/ acrylate.wuxuu leeyahay sifooyinka soo socda: 0dhesiveness aad u fiican, korodhka garaaca bilowga ah iyo heerka qalajinta marka loo isticmaalo buuxinta;iska caabin heer sare ah oo saliid ah;filim cajiib ah.
In la abuuro fiber
Laba codsi oo muhiim ah oo PVA ah waa in loo isticmaalo sida quudinta vinyl iyo wakiilka cabbirka ee textile.Sida alaabta ceeriin ee fiber vinylon, waxay leedahay faa'iidooyinka ahaanshaha sare ee xoogga, nuugista qoyaanka, caabbinta naaxinta, caabbinta iftiinka qorraxda, caabbinta daxalka iyo midabka cad.Waxa kale oo lagu miiqayaa suufka, dhogorta iyo faybarka viscoseka ama iyada lafteeda ayaa lagu miiqayaa. Sida wakiilka cabbirka ee dunta, ma daxaloobayso mana ka xumaan doonto iyada oo si fiican loogu dhejiyo suuf, hemp, polyester iyo fiber viscose.
Pulp & PaperPVA waxay heleen isticmaalka ballaaran ee daaweynta dusha warqadda maadaama ay leedahay dhejis heer sare ah iyo kala firdhisanaan mana saameyn doonto hantida xirayaasha kale ee loo isticmaalo isku darka.Faa'iidooyinka PVA iyadoo la adeegsanayo: Xoogga dusha sare (daabacaadda) ;Xoojinta dhidibka Z-axis (xoogga gudaha warqad); iska caabin laalaab ah, caabbinta abrasive, hagaagsanaan la'aanta, dhalaalid korka oo wanagsan; Caabbinta saliidda iyo dareeraha (hantida xannibaadda).
Filim
PVA waxaa loo isticmaali karaa si loo soo saaro filimka biyaha ku milma iyo film.PVA-caabbinta biyaha ayaa laga heli karaa alaabta la sameeyay taas oo muujinaysa sifooyinka dabiiciga ah ee PVA, kuwaas oo ah, xoogga adag ee sare, caabbinta dareeraha organic iyo cidhiidhiga hawada ayaa labadaba si ballaaran loo isticmaalo warshadaha xirmada, ma aha oo kaliya dharka, laakiin sidoo kale kiimikooyinka, cuntada, kiimikooyinka maalinlaha ah, kiimikooyinka beeraha, dheeha, iwm.
Dejinta kala firdhiso
PVA, oo aad ugu fiican ilaalinta kolloidka oo leh dhaqdhaqaaq sare oo dusha sare ah, ayaa inta badan loo adeegsadaa sida xasiliyaha kala firdhisan ee hakinta polymerization vinyl chloride monomer (VCM).Waxqabadka xabagta PVC si weyn ayaa loo hagaajin karaa iyadoo la dooranayo darajada PVA ee ku habboon oo leh heerka saxda ah ee polymerization iyo hydrolysis.
Waxaan leenahay in ka badan 1000m2 bakhaar loogu talagalay PVA si loo hubiyo in saadka deggan iyo qiimaha tartanka had iyo jeer.
