HydroxyPropyl methylcellose (HPMC) is a nonitics, mvura-soluble cellulose elether application indasitiri dzakasiyana siyana nekuda kwezvinhu zvaro zvakatsanangurwa. Iyi polymer inotorwa kubva ku cellulose, polymer yakasikwa, kuburikidza nemakemikari kugadziridzwa inosanganisira methylation uye hydroxypruproplation. Iyo HPMC inokonzerwa inoratidza kusanganiswa kwezvinhu kubva kune zvavakaderera, zvichiita kuti ive yakakosheswa zvakanyanya mukuumbwa kwakawanda.
Rheological Properties yeHPMC
1. Viscossity uye gelation:
HPMC inozivikanwa kwazvo nekugona kwayo kuumba viscous mhinduro mumvura, kunyangwe pakadzika kwazvo. Iyo viscosity yeHPMC mhinduro dzinoenderana nezvikamu zvinoverengeka, zvinosanganisira molecular uremu, kusvinura, tembiricha, uye dhigiri rekutsiva methyl uye hydroxypruspropyl mapoka. Kazhinji, zviyero zvepamusoro zvinyoro uye zviyero zvinokonzeresa muzvikamu zvepamusoro. Imwe yezvinhu zvinoshamisa zveHPMC ndeyekudzokera shure kweiyo ermal glation. Pakupisa, mapoini HPMC mhinduro pasi pekuchinja kubva kune sol (mvura) kune gel (yakasimba) nyika. Iyi geli inoshanduka-shanduka, ine gel ichidzoka kune sol mamiriro pane kutonhora. Ichi chivakwa chakasarudzika chinonyanya kubatsira mukushandisa zvinoda kupisa-tembiricha
