IHydroxypropyl methyl cellulose (HPMC) iyisengezo esisetshenziswa kakhulu odakeni olusekelwe kusimende ukuthuthukisa ukumelana nokuhlakazeka.Uma yengezwa engxubeni yodaka, i-HPMC yenza ungqimba oluvikelayo oluzungeze izinhlayiya zikasimende, ezivimbela ukuthi zinganamathelani futhi zenze ama-agglomerate.Lokhu kubangela ukusatshalaliswa okufanayo kwezinhlayiya zikasimende kulo lonke ukuhlanganiswa kodaka, okubuye kuthuthukise ukusebenza kwawo jikelele.
Ukumelana nokuhlakazeka kodaka olusekelwe kusimende kubalulekile ngoba kuthinta ukusebenza namandla omkhiqizo wokugcina.Lapho izinhlayiya zikasimende zihlangana ndawonye, zakha i-void kungxube yodaka, engenza isakhiwo sibe buthaka futhi sinciphise ukuqina kwaso.Ngaphezu kwalokho, i-clumping ingenza udaka lube nzima kakhulu ukusebenza nalo, okungaholela ezinkingeni ngesikhathi sokwakhiwa.
I-HPMC ibhekana nalezi zinkinga ngokwenza ngcono ukugeleza nokusebenza kwengxube yodaka.Ngokwenza ungqimba oluvikelayo oluzungeze izinhlayiya zikasimende, i-HPMC inciphisa inani lamanzi adingekayo ukuze kuzuzwe ukuvumelana okusebenzayo, okubuye kunciphise ingozi yokuhlukaniswa nokopha.Lokhu kubangela ingxube ye-homogenous futhi ehlangene, okulula ukuyisebenzisa nokuqeda.
Sekukonke, ukungezwa kwe-HPMC odakeni olusekelwe kusimende kungathuthukisa ukusebenza kwazo ngokuthuthukisa ukumelana kwazo nokuhlakazeka, ukusebenza kahle, nokuqina.
