Ubushyuhe bwa gel ya HPMC

Abakoresha benshi ntibakunze kwita ku kibazo cy'ubushyuhe bwa gel ya hydroxypropyl methyl cellulose HPMC. Muri iki gihe, hydroxypropyl methyl cellulose HPMC muri rusange irangwa n'ubushyuhe, ariko ku bidukikije bimwe na bimwe byihariye n'inganda zidasanzwe, ubushyuhe bw'umusaruro ni bwo bugaragara. Ntabwo bihagije, ibi bikurikira bigaragaza muri make ubushyuhe bwa gel ya hydroxypropyl methylcellulose HPMC.

Ibikubiye mu itsinda rya methoxy bifitanye isano itaziguye n'urugero rwa ether ya cellulose. Ibikubiye mu itsinda rya methoxy bishobora guhindurwa hagenzurwa formula, ubushyuhe bw'impinduka n'igihe cyo gukora. Muri icyo gihe, urugero rwa etherification rugira ingaruka ku rugero rwo gusimbuza hydroxyethyl cyangwa hydroxypropyl. Kubwibyo, kubika amazi kwa ether ya cellulose hamwe n'ubushyuhe bwinshi bwa gel muri rusange ni bibi gato. Iyi nzira yo gukora igomba gusuzumwa, bityo si uko ingano ya methoxy iri hasi, igiciro cya ether ya cellulose kiri hasi, ahubwo igiciro kizaba kinini.

Ingano ya QUALICELL ya hydroxypropyl methyl cellulose HPMC hydroxypropyl ni 25%. Ubushyuhe bwa gel ni ingenzi cyane mu ikoreshwa rya ether ya cellulose. Iyo ubushyuhe bw'ikirere burenze ubushyuhe bwa gel, ether ya cellulose izasohoka mu mazi igatakaza amazi yayo. Ubushyuhe bwa gel ya cellulose ether ya Qualicell ni dogere 65, zishobora guhaza ibyifuzo by'ibidukikije bikoreshwa na mortier na putty (usibye ibidukikije byihariye). Niba uguze QualiCell HPMC, nyamuneka ubimumenyeshe mbere y'igihe niba ufite ibisabwa byihariye.
