Ikibazo cy'ubushyuhe bwa gel ya HPMC

Ku bijyanye n'ikibazo cy'ubushyuhe bwa gel bwaHydroxypropyl Methyl Cellulose HPMC, abakoresha benshi ntibakunze kwita ku kibazo cy'ubushyuhe bwa gel bwa Hydroxypropyl Methyl Cellulose. Muri iki gihe, Hydroxypropyl Methyl Cellulose muri rusange itandukaniye ku bushyuhe bwayo, ariko kuri bimwe mu bidukikije byihariye n'inganda zidasanzwe, ntibihagije kugaragaza gusa ubushyuhe bw'umusaruro. Ibi bikurikira bigaragaza muri make ubushyuhe bwa gel bwa Hydroxypropyl Methyl Cellulose.

Ingano ya Methoxyl ifitanye isano itaziguye n'urugero rwa cellulose sourization, kandi ingano ya Methoxyl ishobora guhindurwa hagenzurwa formula, ubushyuhe bwa reaction n'igihe cya reaction. Muri icyo gihe, urwego rwa inactivation rugira ingaruka ku rugero rwa gusimbuza Hydroxyethyl cyangwa Hydroxypropyl. Kubwibyo, kubika amazi ya cellulose ether hamwe n'ubushyuhe bwinshi bwa gel bizaba bibi. Iyi gahunda yo gukora igomba gusuzumwa, bityo si uko ikiguzi cya cellulose ether kiba kiri hasi niba ingano ya Methoxy iri hasi, ahubwo igiciro kizaba kinini.

Ubushyuhe bwa gel bugenwa n'amatsinda ya methoxyl, naho uburyo amazi abikwamo bugenwa n'amatsinda ya Hydroxypropoxy. Hari amatsinda atatu gusa ashobora gusimburwa kuri selulose. Shaka ubushyuhe bukwiye bwo gukoresha, uburyo amazi abikwamo, hanyuma umenye icyitegererezo cy'iyi selulose.

Ubushyuhe bwa gel ni ikintu cy'ingenzi mu ikoreshwa ryaeteri ya seluloseIyo ubushyuhe bw'ikirere burenze ubushyuhe bwa gel, eteri ya cellulose izatandukanywa n'amazi kandi igatakaza amazi yayo. Ubushyuhe bwa gel ya eteri ya cellulose ku isoko bushobora guhaza ibyifuzo by'ibidukikije bikoreshwa na morti (usibye ibidukikije byihariye). Ku giti cyanjye ndatekereza ko atari ngombwa kwita cyane ku gipimo cy'imikorere y'ubushyuhe bwa gel mu gihe cyo gukoresha morti. Birumvikana ko ikorwa rya eteri ya cellulose Abakora bagomba kubyitaho.
