Nibihe bikoresho nyamukuru bya hydroxypropyl methylcellulose (HPMC)?

Hydroxypropylmethylcellulose (HPMC) ni selulose ikomoka cyane mu nganda zitandukanye.Imikoreshereze yingenzi ya HPMC nkiyongera, stabilisateur na emulisiferi mu biribwa, imiti n’amavuta yo kwisiga.HPMC ikoreshwa kandi mubikorwa byubwubatsi nkinyongera ya sima, nkigifuniko cyibinini na capsules, kandi nkigisubizo cyamaso.Ibikoresho nyamukuru bya HPMC ni selile na reagent ya chimique.

Cellulose:

Cellulose nigikoresho nyamukuru cyo gukora HPMC.Cellulose ni polymer karemano iboneka murukuta rw'ibimera kandi ni polymer karemano cyane kwisi.Imiti yimiti ya selile isa na HPMC, ituma iba ibikoresho byiza bibyara umusaruro wa HPMC.Cellulose ikomoka ahantu hatandukanye, harimo ibiti, ipamba, nibihingwa bitandukanye.

Inkomoko ikunze kugaragara ya selile ikoreshwa mubikorwa bya HPMC ni inkwi.Ibiti biva mu biti bikomoka ku biti byoroshye nka spuce, pinusi na firimu.Ibiti bivangwa nimiti bivura lignine na hemicellulose, hasigara selile nziza.Cellulose isukuye noneho irahanagurwa kandi irakaraba kugirango ikureho umwanda wose.

Cellulose ikoreshwa mu musaruro wa HPMC igomba kuba yujuje ubuziranenge kandi hagomba gukurikizwa ingamba zikomeye zo kugenzura ubuziranenge kugira ngo selulose isukure.Isuku ya selile irakomeye kuko umwanda ushobora kugira ingaruka kumiterere yibicuruzwa byanyuma.

Imiti ya shimi:

Umusaruro wa HPMC urasaba gukoresha imiti itandukanye.Imiti ikoreshwa mu gukora HPMC irimo oxyde ya propylene, methyl chloride, hydroxide ya sodium, aside hydrochloric, nibindi.

Okiside ya propylene ikoreshwa mu gukora hydroxypropyl selulose (HPC), hanyuma igahita ikoreshwa na methyl chloride kugirango ikore HPMC.HPC ikorana na methyl chloride kugirango isimbuze amwe mumatsinda ya hydroxyl kumurongo wa selile hamwe na mikorobe na hydroxypropyl, bityo bigakora HPMC.

Sodium hydroxide ikoreshwa mugukora HPMC kugirango yongere agaciro ka pH igisubizo cyibisubizo bifasha gushonga selile.

Mugihe cyo kubyara HPMC, aside hydrochloric ikoreshwa muguhindura pH agaciro k'igisubizo.

Imiti ikoreshwa mu musaruro wa HPMC igomba kuba ifite isuku nyinshi, kandi imiterere yimikorere igomba kugenzurwa neza kugirango ireme ryibicuruzwa byanyuma.

mu gusoza:

Ibikoresho nyamukuru bya HPMC ni selile na reagent ya chimique.Cellulose, ikomoka ahantu hatandukanye harimo ibiti, ipamba, nibihingwa bitandukanye, nibikoresho fatizo byibanze byo gukora HPMC.Imiti ikoreshwa mu musaruro wa HPMC irimo oxyde ya propylene, methyl chloride, hydroxide ya sodium na aside hydrochloric.Umusaruro wa HPMC urasaba ingamba zihamye zo kugenzura ubuziranenge kugirango harebwe niba ibikoresho fatizo bifite ubuziranenge n’ibicuruzwa byanyuma.HPMC ikoreshwa cyane mu nganda zinyuranye kandi ifite porogaramu zitandukanye kubera imiterere yihariye.
