IHydroxypropylmethylcellulose (HPMC) iyinhlanganisela eguquguqukayo evame ukusetshenziswa embonini yezokwakha, okuhlanganisa ukwakheka kukakhonkolo.Nakuba ingase ingathuthukisi ngokuqondile ukuqina kukakhonkolo, idlala indima ebalulekile ekuthuthukiseni izakhiwo ezihlukahlukene zengxube kakhonkolo.
1. Isingeniso se-hydroxypropyl methylcellulose:
IHydroxypropyl methylcellulose (HPMC) iyi-ether ye-cellulose eguquliwe etholakala kuma-polymers emvelo.Ngenxa yezakhiwo zayo eziyingqayizivele, isetshenziswa kabanzi njengesengezo ezintweni zokwakha.Kokukhonkolo, i-HPMC ivamise ukusetshenziswa njenge-ejenti egcina amanzi, i-thickener, ne-binder.Ukwakheka kwayo kwamakhemikhali kwenza kube lula ukwenza ifilimu evikelayo ezungeze izinhlayiya zikasimende, okuthinta izici ze-rheological kanye nemishini yengxube kakhonkolo.
2.Iqhaza le-HPMC ekuqiniseni ukhonkolo:
Ukugcinwa kwamanzi nokusebenza:
I-HPMC isebenza njenge-ejenti egcina amanzi, ivimbela ukulahlekelwa kwamanzi amaningi ngesikhathi sokuqala sokuphulukiswa okukhonkolo.
Lokhu kugcinwa kwamanzi okuthuthukisiwe kusiza ukugcina ukusebenza kahle, okuholela ekubekweni okungcono kanye nokuminyana kukakhonkolo.
Thuthukisa ukunamathela:
Izakhiwo zefilimu ze-HPMC zisiza ukuthuthukisa ukunamathela phakathi kwezinhlayiya zikasimende, okuholela ku-matrix kakhonkolo ehlangene futhi ehlala isikhathi eside.
Yehlisa ukuhlukana nokopha:
I-HPMC isiza ekunciphiseni ubungozi bokuhlukaniswa nokopha ezixubeni zikakhonkolo, okuholela kumkhiqizo wokuphela ofanayo, ozwakala kahle wesakhiwo.
Isikhathi sokusetha esithuthukisiwe:
Ukusetshenziswa kwe-HPMC kungathonya isikhathi sokusetha sikakhonkolo, ngaleyo ndlela kunikeze ibhalansi phakathi kokusebenza nokuthuthukiswa kwamandla okusheshisiwe.
Umthelela ezicini zemishini:
Nakuba i-HPMC ngokwayo ingase ingakuthuthukisi ngokuqondile ukuqina kukakhonkolo, umthelela wayo ekusebenzeni nasekunamatheleni ungathinta ngokungaqondile izici zemishini zikakhonkolo, kusize ukwakha izakhiwo eziqinile nezihlala isikhathi eside.
3. Amanothi nezinqubo ezihamba phambili:
Ukulawula umthamo:
Umthamo olungile we-HPMC ubalulekile.Ukweqisa ngokweqile kungase kubangele imiphumela emibi, kuyilapho ukwehlisa umthamo kungase kunganikezi ukuthuthukiswa okudingekayo.
ukuhambisana:
Ukuhambisana nezinye izixube zikakhonkolo nezinto zokwakha kufanele kucatshangelwe ukuze kugwenywe noma yikuphi ukusabela okubi okungase kuphazamise izakhiwo zengxube kakhonkolo.
Indlela yokwelapha:
Nakuba i-HPMC isiza ukugcina amanzi, izindlela ezifanele zokuphulukisa kufanele zisetshenziswe ukuze kuqinisekiswe ukuqina kwesikhathi eside kukakhonkolo.
Nakuba i-HPMC ingeyona i-ejenti eqondile ethuthukisa ukuqina kukakhonkolo, ukusetshenziswa kwayo kuzingxube zikakhonkolo kungathuthukisa ukusebenza, ukunamathela, nezinye izakhiwo, ngaleyo ndlela kuthuthukise ngokungaqondile ukuqina kukonke kwezakhiwo zikakhonkolo.I-HPMC kumele ibhekwe njengengxenye yendlela edidiyelwe yokuklama okuxubene okukhonkolo kanye nezinqubo zokwakha ukuze kuzuzwe izakhiwo ezihlala isikhathi eside neziqinile.
