HPMC E50
EiponCellHPMC E50 Hydroxypropyl methylcellulose waa nooc caan ah oo kala firdhiso oo loo isticmaalo warshadaha chloride polyvinyl (PVC).Waxaa la adeegsadaa inta lagu jiro polymerization-ka vinyl chloride si wax ku ool ah loo yareeyo xiisadda dhexda ah ee u dhaxaysa vinyl chloride monomer (VCM) iyo biyaha.Hoos u dhigista xiisaddan waxay gacan ka geysataa inay si isku mid ah oo xasilloon u kala firdhiso VCM-da dhex dhexaadinta biyaha.Intaa waxaa dheer, waxay gacan ka geysataa ka hortagga isku-darka dhibcaha VCM ee bilawga habka polymerization waxayna joojisaa isku-dhafka u dhexeeya walxaha polymer-ka ee dhexdhexaadka iyo kuwa dambe.Nidaamka polymerization ee hakinta, EipponCellHPMC E 50 Hydroxypropyl methylcellulose waxay u adeegtaa ujeeddo laba ah oo kala firidhsan iyo ilaalinta xasilloonida.

HPMC F 50
EipponCellHPMC F 50, hydroxypropyl methyl cellulose, wuxuu u shaqeeyaa sida kala firdhiso warshadaha PVC.Nidaamka polymerization hakinta ee chloride vinyl, kala firdhisyada sida caadiga ah loo isticmaalo waxaa ka mid ah xeryahooda polymer sida alkolada polyvinyl iyo eter cellulose.Marka la walaaqo, waxay fududeeyaan samaynta dhibco leh qiyaaso ku habboon.Awooddan waxaa loo tixraacaa sida awoodda kala firdhiso.Intaa waxaa dheer, firdhiyahu waxa lagu daaraa dusha sare ee dhibco faynuus ah oo koloriin ah, taas oo samaynaysa lakab difaac ah oo ka hortagaya isu geynta dhibcaha oo dejinaya.Saamayntan waxaa loo yaqaana awoodda haynta kolloid ee kala firdhisiyaha.
