Hydroxypropyl Methyl Cellulose HPMC nghọta

Nnukwu nghọta na arụmọrụ kwụsiri ike.

HPMC nwere ihe onwunwe nke thermal gelation. Ngwaahịa aqueous ngwọta na-ekpo ọkụ na-etolite a gel na precipitates, na mgbe dissolves mgbe obi jụrụ. Okpomọkụ gelation nke nkọwa dị iche iche dị iche iche. Solubility dị iche na viscosity. Na ala viscosity, ka ukwuu solubility. Nkọwa dị iche iche nke HPMC nwere ụfọdụ ọdịiche dị na ihe onwunwe ha, na mgbasa nke HPMC na mmiri adịghị emetụta uru pH.
