HydroxyPropyl MethycellllAlose (HPMC) ni polymer nyinshi ikoreshwa cyane mu nganda zinyuranye harimo imiti, ibiryo, kubaka no kwisiga. Ariko, kimwe nibindi bigo byose, HPMC ifite ingorane zimwe na zimwe.
1. Ikibazo Cyinshi: HPMC isanzwe ishonje mumazi na kama kemanda nka methanol na ethanol. Ariko, ibibazo byayo biratandukanye bitewe nibintu nkuburemere bwa molecular, urwego rwo gusimbuza, nubushyuhe. Icyiciro kinini cya HPMC cya HPMC kirashobora kwerekana umubare wica buhoro, bishobora kuba ikibazo muri porogaramu zisaba imvururu yihuse.
2. Impinduka za vino: viscozetity yo ibisubizo bya HPMC biterwa nibintu byinshi, harimo kwibanda, ubushyuhe, PH na Shear. Gutandukana muri viscosiya birashobora gutera ingorane muguhimba ibicuruzwa bihoraho, cyane cyane munganda nka farucetics hamwe no kwisiga aho kugenzura neza imiterere yamarangamutima ari ngombwa.
3. Hygroscopique: HPMC yahise akuramo ubushuhe kuva ahantu hazengurutse ibidukikije, bigatuma habaho impinduka mumitungo yacyo nka virusi cyangwa imyitwarire itemba. Iyi Hygroscopique irashobora guteza ibibazo mugihe cyo kubika, gufata no gutunganya, cyane cyane mubihe bitoroshye.
4. Kwangiza ikirere: Kubushyuhe Burebure, HPMC izatesha agaciro ubushyuhe, bikaviramo impinduka muburemere bwa molekile, vicosity nibindi byuranga. Ibi birashobora kubaho mugihe cyo gutunganya mugihe cyumye cyangwa gishyushye gishongeshejwe, bigatera ibibazo byiza byibicuruzwa hamwe no gutesha agaciro.
5. Ibibazo Byuzuza: Nubwo HPMC isanzwe ijyanye nabandi bitwazo benshi hamwe nabashyingo, ibibazo byo guhuza bishobora kuvuka mubitera bimwe. Imikoranire nibindi bikoresho birashobora kugira ingaruka kumutekano, kukecururizwa cyangwa ibinyabuzima byanyuma, ibikoresho byanyuma bigomba gutorwa no kuba byiza.
6.. Munsi ya alkaline, ibisubizo bya HPMC birashobora kugabanuka cyangwa kwicisha bugufi, bikabuza kuba muburyo bumwe. Ku rundi ruhande, acidic Ph irashobora gutesha agaciro HPMC igihe, bigira ingaruka ku bicuruzwa no gutuza.
7. Ibibazo bigize film: HPMC ikunze gukoreshwa mugukunda ibipimo bya farumasi na capsules bitewe numutungo wa firime. Ariko, kubona firime imwe kandi idafite inenge irashobora kugorana, cyane cyane kumanota menshi ya HPMC. Ibintu nko gukama, imiterere ya subrete hamwe no gutwikira bigomba kuba byiza byitondewe kugirango hakemurwe neza.
8. Ibitekerezo byo kugenzura: Ibisabwa kugenzura nibisobanuro kuri HPMC irashobora gutandukana bitewe na porogaramu igenewe nakarere ka geografiya. Kugenzura niba amabwiriza akurikije amabwiriza akurikije amabwiriza agenga cyangwa abashinzwe ibiryo, ashobora kuba inzira igoye kandi itwara igihe, cyane cyane ibicuruzwa bikoreshwa mu nganda ziteganijwe.
9. Ibitekerezo bya soTe: HPMC ihenze kuruta ibindi bikomoka kuri selile na polymers bikoreshwa mubisabwa bisa. Ibishushanyo byagutse birashobora kugabanya imikoreshereze cyangwa bisaba iterambere ryibiciro-bifatika muguhitamo ibipimo byingenzi, ibikoresho byo gutunganya, cyangwa ubundi bwiza.
10. Ingaruka y'ibidukikije: Umusaruro no kujugunywa HPMC birashobora kugira ingaruka zibidukikije, harimo no gukoresha ingufu, guta ibyumba no guhumanya. Nkibira bihinduka impungenge zinganda zikikije isi, hakenewe ubushakashatsi bwo gushakisha ubundi buryo bwangiza urugwiro kuri HPMC cyangwa gushyira mubikorwa ibikorwa birambye.
Mugihe hydroxypropyl methylcellse itanga inyungu nyinshi hamwe nibisabwa munganda butandukanye, ni ngombwa kumenya ibibazo n'imbogamizi zijyanye no kuyikoresha. Gukemura ibi bibazo ukoresheje igishushanyo mbonera, inzira yo guhitamo neza, no kubahiriza amabwiriza ngengamikorere birashobora gufasha kugwiza inyungu za HPMC mugihe ugabanya ibibi byayo.
