I-Hydroxypropyl Methylcellulose njengee-agent ezahlulayo, iimveliso ezifunyenweyo zineengqungquthela ezicwangcisiweyo kunye nezikhululekileyo, ubuninzi obubonakalayo obufanelekileyo kunye nokusebenza kakuhle kokusebenza.Nangona kunjalo, ukusetyenziswa kweHydroxypropyl Methylcellulose yodwa kunokuba negalelo ekungaguqukiyo okuhle kwe-resin nangona kunjalo.Ukusebenza ngokubanzi kwe-resin kubi.Ukusetyenziswa kwekhompawundi ye-hydroxypropyl methylcellulose kunye nedigri ye-alcoholic eyahlukeneyo eyahlukeneyo yepolyvinyl yotywala inokwenza ukusebenza kweemveliso kube ngcono, umgangatho ulula ukulawula kwaye kwangaxeshanye unokunciphisa iindleko.I-arhente yokusabalalisa iyona nto iphambili echaphazela i-particle shape of polyvinyl chloride resin.Okuncinci ukunyanzeliswa komphezulu wesisombululo esinamanzi se-agent echithachithayo ngokubanzi kunye ne-interfacial tension kunye ne-Vinyl chloride monomer kukuba, i-droplets ye-VCM ingcono kakhulu inokusasazwa.Kwaye ke i-particle diameter ye-PVC resin iya kuba ncinane.Okona kunamandla amandla okukhusela e-arhente yokusabalalisa, ngokusondeleyo i-PVC efunyenweyo i-resin particles iya kuba kwaye incinci i-porosity iya kuba.Kwaye i-intergranular coalescence nayo inzima ngakumbi, ngoko kulula ukwenza i-resins.
Umzekelo, kwinkqubo yokusasazwa kwe-compound ye-PVA kunye ne-HPC, kokukhona inqanaba le-alcoholsis le-PVA liphezulu, kokukhona ukuxinana komphezulu wesisombululo samanzi kuya kuba namandla kwaye kuya kuba namandla amandla okukhusela, ngelixa i-concentration ethile ye-hydroxypropyl methylcellulose isiphumo esihle sokusasazeka.Ke ngoko, ukusebenzisa i-PVA eneqondo eliphezulu le-alcoholsis njengeyona nto iphambili
i-arhente yokusasaza, kunye nokudibanisa a
isixa esithile se-hydroxypropyl methylcellulose
njenge-arhente yokusabalalisa i-polymerization yokumiswa, kulula ukulungiselela i-resin ye-PVC enokuthi ihlangabezane neemfuno ze-particle morphology.Umzekelo, kwinkqubo yokusasazwa kwe-compound ye-PVA kunye ne-HPC, kokukhona inqanaba le-alcoholsis le-PVA liphezulu, kokukhona ukuxinana komphezulu wesisombululo samanzi kuya kuba namandla kwaye kuya kuba namandla amandla okukhusela, ngelixa i-concentration ethile ye-hydroxypropyl methylcellulose isiphumo esihle sokusasazeka.
