IHydroxypropyl Methylcellulose njengeearhente zokwahlulahlula, iimveliso ezifunyenweyo zinamasuntswana acwangcisiweyo nakhululekileyo, uxinano olufanelekileyo olubonakalayo kunye nokusebenza kakuhle kokucubungula. Nangona kunjalo, ukusetyenziswa kweHydroxypropyl Methylcellulose yodwa kunokunceda ekuguqukeni okuhle kwe-resin nangona kunjalo. Ukusebenza ngokubanzi kwe-resin akukuhle. Ukusetyenziswa kwe-hydroxypropyl methylcellulose kunye ne-alcohol ye-polyvinyl alcohol eyahlukeneyo kunokwenza ukusebenza kweemveliso kube ngcono, umgangatho ube lula ukuwulawula kwaye kwangaxeshanye kunokunciphisa iindleko. Iarhente yokusasaza yeyona nto iphambili echaphazela imo yamasuntswana e-resin ye-polyvinyl chloride. Okukhona uxinzelelo lomphezulu wesisombululo samanzi seearhente zokusasaza ngokubanzi kunye noxinzelelo lwe-interfacial kunye ne-Vinyl chloride monomer zincinci, kokukhona amaconsi e-VCM anokusasazwa. Kwaye ke ububanzi besuntswana ye-resin ye-PVC buya kuba mncinci. Okukhona amandla okukhusela earhente yokusasaza eqina, kokukhona amasuntswana e-resin ye-PVC afunyenweyo aya kuba kufutshane kwaye kokukhona amasuntswana e-porosity aya kuba mancinci. Kwaye i-coalescence ye-intergranular nayo inzima ngakumbi, ngoko ke kulula ukwenza ii-resin.
Umzekelo, kwinkqubo yokusasazwa kwe-PVA kunye ne-HPC, xa inqanaba le-PVA liphezulu le-alcoholization, uxinzelelo lomphezulu wesisombululo samanzi luya kuba lukhulu kwaye amandla okukhusela aya kuba namandla ngakumbi, ngelixa uxinzelelo oluthile lwe-hydroxypropyl methylcellulose lunefuthe elihle lokusasazeka. Ke ngoko, ukusebenzisa i-PVA enezinga eliphezulu le-alcoholization njengeyona nto iphambili
iarhente yokusasaza, kunye nokudibanisa
isixa esithile se-hydroxypropyl methylcellulose
njengesixhobo sokusasaza i-polymerization yokumiswa, kulula ukulungiselela i-resin ye-PVA enokuhlangabezana neemfuno zesimo se-particle. Umzekelo, kwinkqubo yokusasaza i-PVA kunye ne-HPC, xa i-PVA iphezulu, uxinzelelo lomphezulu wesisombululo samanzi luya kuba lukhulu kwaye amandla okukhusela aya kuba namandla ngakumbi, ngelixa uxinzelelo oluthile lwe-hydroxypropyl methylcellulose lunefuthe elihle lokusasaza.
