Ikibazo cy'ubushyuhe bwa gel ya Hydroxypropyl methylcellulose HPMC

Ku bijyanye n'ubushyuhe bwa gel bwa hydroxypropyl methyl celluloseHPMC, abakoresha benshi ntibakunze kwita ku bushyuhe bwa gel bwa hydroxypropyl methyl cellulose. Ubu hydroxypropyl methyl cellulose ikunze gutandukanywa bitewe n'ubushyuhe bwayo, ariko kuri bimwe mu bidukikije byihariye n'inganda zidasanzwe, ntibihagije kugaragaza ubushyuhe bw'umusaruro gusa. Ibi bikurikira bigaragaza muri make ubushyuhe bwa gel bwa hydroxypropyl methylcellulose.

Ibikubiye mu matsinda ya methoxy bifitanye isano itaziguye n'urugero rwa dialysis ya cellulose, kandi ingano y'amatsinda ya methoxy ishobora guhindurwa hakoreshejwe kugenzura formula, ubushyuhe bw'inyito n'igihe cyo gukora. Muri icyo gihe, ingano ya carboxylation igira ingaruka ku rugero rwo gusimbuza hydroxyethyl cyangwa hydroxypropyl. Kubwibyo, kubika amazi ya ether za cellulose zifite ubushyuhe bwinshi bwa gel muri rusange ni bibi gato. Iyi gahunda yo gukora igomba gusuzumwa, bityo si uko ingano ya methoxy iri hasi, igiciro cyo gukora ether ya cellulose kiri hasi, ahubwo igiciro cyayo kizaba kiri hejuru.

Ubushyuhe bwa gel bugenwa n'itsinda rya methoxy, naho uburyo amazi abikwamo bugenwa n'itsinda rya 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 izatandukana n'amazi kandi itakaze amazi. Ubushyuhe bwa gel ya eteri ya cellulose ku isoko bushobora guhaza ibyifuzo by'ibidukikije aho mortier ikoreshwa (usibye ibidukikije byihariye). Abakora bagomba kubyitaho.
