Astaamaha Alaabta: Kala-firdhinta: Waxqabadka kala firdhinta hakinta ee ugu fiican, adoo hagaajinaya xiisadda dusha sare iyo feejignaanta, monomer-ka ayaa loo kala firdhi doonaa qaybo yaryar. Joojinta: hagaajinta xasiloonida kulaylka xabagta iyo xakamaynta qaybinta cabbirka walxaha, hagaajinta qaabka qaybinta iyo qaybinta viscosity, yaraynta dhacdooyinka kalluunka. Adsorbability: waxay wanaajisaa tayada xabagta iyo alaabada warshadaysan, si ay xabagta PVC u soo saarto wax maran, kor u qaad nuugista balaastikada.
Nidaamka polymerization PVC diyaariyey HPMC oo tayo sare leh, marka lagu daro in la hubiyo in wax qabadku la kulmo heerarka caalamiga ah, laakiin sidoo kale waxa uu leeyahay sifooyin muuqaal wanaagsan oo muuqda, sifooyinka walxaha aad u fiican iyo dabeecad dhalaalaysa rheological aad u fiican. Nidaamka kala firdhisan ee xarunta, khamriga polyvinyl (PVA) oo leh heerar kala duwan oo alkolysis ah iyo polymerization iyo hydroxypropyl methylcellulose (HPMC) isku-dhafka isku-dhafka ah ayaa ka fiican, kaas oo u oggolaanaya porosity of resin, iyo nuugista caagagga ayaa sidoo kale faa'iido leh.
