HPMC yo kubaka

Hydroxypropyl methyl selulose (HPMC) ni selile itari ionic selile ikomoka kuri selile naturel. Ikoreshwa cyane mubwubatsi nkibikoresho byibyimbye, binder, ikwirakwiza, emulifiseri, umukozi ukora firime, kurinda colloid, hamwe nu guhagarika ibikorwa.

HPMC ni umweru kugeza kuri-cyera, nta mpumuro nziza, uburyohe, kandi ifu idafite uburozi. Irashobora gushonga mumazi akonje kandi ikora igisubizo gisobanutse neza. Ntishobora gukemuka mumashanyarazi nka Ethanol, acetone, na benzene. HPMC ni anionic polysaccharide igizwe numurongo ugizwe numurongo wa D-glucose uhujwe na β-1,4-glycosidic. Ikorwa nigisubizo cya methyl chloride na hydroxypropyl chloride hamwe na selile.

HPMC ikoreshwa cyane mubwubatsi kubera ibyiza byayo. Irashobora gukoreshwa nkibintu byiyongera kugirango yongere ubwiza bwibisubizo byamazi no kunoza imikorere ya sima na minisiteri. Irashobora kandi gukoreshwa nkigikoresho cyo kunoza ifatizo rya sima na minisiteri kubutaka. HPMC irashobora kandi gukoreshwa nkikwirakwiza kugirango igabanye amazi ya sima na minisiteri no kunoza imikorere yabo. Byongeye kandi, HPMC irashobora gukoreshwa nka emulisiferi kugirango itezimbere ituze rya sima hamwe na minisiteri.

HPMC irashobora kandi gukoreshwa nkigikorwa cyo gukora firime kugirango irusheho guhangana n’amazi ya sima na minisiteri. Irashobora kandi gukoreshwa nka colloid ikingira kugirango igabanye ubuso bwa sima na minisiteri no kunoza imikorere yabo. Hanyuma, HPMC irashobora gukoreshwa nkumukozi uhagarika kunoza ihagarikwa rya sima na minisiteri.

HPMC ninyongera kandi ihindagurika kubikorwa byubaka. Irashobora kunoza imikorere ya sima na minisiteri, kugabanya amazi yabo, kunoza imiterere yabyo, no kunoza amazi. Byongeye kandi, irashobora gukoreshwa nka emulifisiyeri, umukozi ukora firime, kurinda colloid, no guhagarika ibikorwa. HPMC ninyongera yubukungu kandi itekanye ishobora gukoreshwa mugutezimbere imikorere ya sima na minisiteri.
