Gukemura HPMC

Hydroxypropyl methylcellulose (HPMC) irashonga mumazi, nimwe mumitungo yingenzi kandi ikagira uruhare muburyo bwinshi mubikorwa bitandukanye. Iyo wongeyeho amazi, HPMC iratatana na hydrata, ikora ibisubizo bisobanutse kandi bigaragara. Ubushobozi bwa HPMC buterwa nibintu byinshi, harimo urugero rwo gusimbuza (DS), uburemere bwa molekile ya polymer, nubushyuhe bwumuti.

Muri rusange, HPMC ifite agaciro ka DS yo hasi ikunda gushonga cyane mumazi ugereranije na HPMC hamwe nagaciro ka DS. Muri ubwo buryo, HPMC ifite uburemere buke bwa molekuline irashobora kugira umuvuduko mwinshi ugereranije nuburemere buke bwa molekile.

Ubushyuhe bwigisubizo nabwo bugira ingaruka kumikorere ya HPMC. Ubushyuhe bwo hejuru busanzwe bwongera imbaraga za HPMC, bigatuma habaho gushonga vuba na hydrated. Nyamara, ibisubizo bya HPMC birashobora guhura na gelation cyangwa gutandukanya icyiciro hejuru yubushyuhe bwo hejuru, cyane cyane mubitumbiro byinshi.

Ni ngombwa kumenya ko mugihe HPMC ishonga mumazi, igipimo nintera yo guseswa birashobora gutandukana bitewe nurwego rwihariye rwa HPMC, imiterere yimiterere, nibindi byongeweho byose biri muri sisitemu. Byongeye kandi, HPMC irashobora kwerekana imiterere itandukanye yo gukemura ibibazo mumashanyarazi cyangwa ubundi buryo butari amazi.

gukomera kwa HPMC mumazi bituma iba polymer yingirakamaro kubikorwa bitandukanye aho guhindura viscosity, gukora firime, cyangwa nibindi bikorwa byifuzwa.
