Ni irihe tandukaniro riri hagati ya methylcellulose na HPMC

Methylcellulose (MC) na Hydroxypropyl Methylcellulose (HPMC) byombi bikoreshwa cyane mu mazi ya elegitoronike ya elegitoronike, ikoreshwa cyane mu biribwa, imiti, ubwubatsi no kwita ku muntu ku giti cye.

1. Itandukaniro ryimiterere

Methylcellulose (MC):

Methylcellulose ni inkomoko ya selile yabonetse mugusimbuza igice cyamatsinda ya hydroxyl ya selile na methyl (-OCH3).

Imiterere yimiti iroroshye cyane, igizwe na skeleton ya selile hamwe na methyl.

Hydroxypropyl Methylcellulose (HPMC):

HPMC yashizweho no kurushaho kumenyekanisha hydroxypropyl (-C3H7O) ishingiye kuri methylcellulose.

Ihinduka ryimiterere rituma rirushaho kuba byiza mubijyanye no gukemura no kuranga amazi.

2. Gukemura

Methylcellulose irashobora gushonga byoroshye mumazi akonje, ariko ntishobora gushonga mumazi ashyushye, kandi mubisanzwe irerekana imiterere ya colloidal. Ibi bituma imitungo ya MC ishobora guhinduka mugihe ubushyuhe buzamutse.

Hydroxypropyl Methylcellulose irashobora gushonga neza mumazi akonje kandi ashyushye, kandi gukomera kwayo nibyiza kuruta methylcellulose. HPMC irashobora kugumana amazi yayo mubushyuhe bwinshi kandi irakwiriye gukoreshwa bisaba kuvura ubushyuhe.

3. Ibiranga ubukonje

Methylcellulose ifite ubukonje buke ugereranije kandi irakwiriye kubisaba bidasaba ubukonje bwinshi.

Hydroxypropyl methylcellulose ifite ubukonje bwinshi kandi irashobora guhindurwa muguhindura uburemere bwa molekile hamwe nintera yo gusimburwa. Ibi bituma HPMC ihinduka cyane mubikorwa bitandukanye, cyane cyane mubwubatsi ninganda zimiti.

4. Ahantu ho gusaba

Methylcellulose ikoreshwa kenshi mu nganda z’ibiribwa nkibyimbye, emulisiferi na stabilisateur, kandi ikoreshwa no mubicuruzwa bimwe na bimwe bya farumasi nkibikoresho byo gutwikira imiti.

Hydroxypropyl methylcellulose ifite porogaramu yagutse. Usibye ibiryo na farumasi, ikoreshwa cyane mubikoresho byubaka (nka minisiteri yumye) hamwe nibicuruzwa byawe bwite (nk'amavuta y'uruhu na shampo) bitewe nuburyo bwiza bwo gukora firime no gufatira hamwe.

5. Ibiranga imikorere

Methylcellulose ifite amazi meza kandi ikora firime kandi ikoreshwa mubicuruzwa bigomba kugumana ubushuhe.

Hydroxypropyl methylcellulose ifite ubushyuhe bwiza kandi ikora neza cyane ya firime usibye kubika amazi, bityo ikora neza mubisabwa hamwe no kuvura ubushyuhe bwinshi.

6. Umutekano n’umutekano

Byombi ni inyongeramusaruro yibiribwa kandi mubisanzwe bifatwa nkumutekano. Ariko, HPMC irashobora gukundwa mubisabwa bimwe bitewe nuko ihagaze neza kandi ihuza.

Methylcellulose na hydroxypropyl methylcellulose biratandukanye cyane muburyo bwa chimique, solubilité, ibiranga viscosity hamwe nibisabwa. Guhitamo ibikoresho bikwiye akenshi biterwa nibikenewe bya porogaramu runaka. MC ibereye muburyo bworoshye bwo kubyimba no gutezimbere, mugihe HPMC irakwiriye cyane mubikorwa byinganda ninganda zubucuruzi bitewe nubushobozi bwayo bukomeye hamwe nubushobozi bwo guhindura ibishishwa.
