Itandukaniro hagati ya CMC na HEMC

Carboxymethylcellulose (CMC) na Hydroxyethyl methylcellulose (HEMC) ni ubwoko bubiri bukomoka kuri selile bukunze gukoreshwa mu nganda zitandukanye, harimo ibiribwa n’imiti. Byombi CMC na HEMC ni polymers zishonga mumazi zikomoka kuri selile, ariko zifite imitungo itandukanye kandi zikoreshwa mubikorwa bitandukanye. Muri iyi nyandiko, tuzasesengura itandukaniro riri hagati ya CMC na HEMC.

Imiterere yimiti
Imiterere yimiti ya CMC na HEMC irasa, kuko byombi bikomoka kuri selile. CMC ikorwa no gukora selile hamwe na aside ya chloroacetike kugirango itange amatsinda ya carboxymethyl, mugihe HEMC ikorwa no gukora selile hamwe na okiside ya Ethylene na methyl chloride kugirango itange hydroxyethyl na methyl.

Gukemura
Imwe muntandukanyirizo nyamukuru hagati ya CMC na HEMC nubushobozi bwabo mumazi. CMC irashobora gushonga cyane mumazi kandi irashobora gukora igisubizo gisobanutse, kiboneka neza nubwo cyaba gito. Ibinyuranye, HEMC ntishobora gushonga mumazi kurusha CMC kandi mubisanzwe bisaba gukoresha imiti, nka Ethanol cyangwa alcool ya isopropyl, kugirango ishonga burundu.

Viscosity
Irindi tandukaniro rikomeye hagati ya CMC na HEMC nubwiza bwabo. CMC iragaragara cyane kandi irashobora gukora igisubizo kimeze nka gel iyo gishonge mumazi. Ibi bituma CMC iba nziza gukoreshwa mubisabwa aho bisabwa kubyimba cyangwa gusya, nko mu nganda zibiribwa zo gukora isosi no kwambara. Ibinyuranye, HEMC ifite ubukonje buke ugereranije na CMC kandi mubisanzwe ikoreshwa nkibihindura umubyimba cyangwa rheologiya mubisabwa aho hakenewe igisubizo gito cyane.

pH Guhagarara
Muri rusange CMC irahagaze neza kurwego rwagutse rwa pH kuruta HEMC. CMC ihagaze neza mubidukikije bya acide na alkaline, bigatuma biba byiza gukoreshwa munganda zibiribwa, aho agaciro ka pH gashobora gutandukana cyane. Ibinyuranye, HEMC irahagaze neza muri acide nkeya kubidukikije bidafite aho bibogamiye kandi birashobora gusenyuka hejuru ya pH.

Ubushyuhe
CMC na HEMC byombi birahagaze hejuru yubushyuhe butandukanye, ariko hariho itandukaniro mumashanyarazi yabo. CMC ihagaze neza cyane kurusha HEMC kandi irashobora kugumana imiterere yayo mubushyuhe bwinshi. Ibi bituma CMC iba nziza gukoreshwa mubisabwa aho ubushyuhe bwo hejuru burimo, nko mu bicuruzwa bitetse. Ku rundi ruhande, HEMC, ifite ubushyuhe buke buri munsi ya CMC kandi irashobora gucika ku bushyuhe bwinshi.

Porogaramu
Byombi CMC na HEMC bikoreshwa mubikorwa bitandukanye mubikorwa bitandukanye. Ubusanzwe CMC ikoreshwa nkibyimbye, stabilisateur, na emulisiferi mu nganda zibiribwa kubicuruzwa nka ice cream, isosi, hamwe no kwambara. Irakoreshwa kandi mubikorwa bya farumasi nkibihuza, bidahwitse, kandi bihagarika. Ubusanzwe HEMC ikoreshwa nkibyimbye, binder, na rheologiya ihindura mubikorwa byubwubatsi kubicuruzwa nkamabara, amarangi, hamwe nibifatika. Irakoreshwa kandi mubikorwa bya farumasi nkibihuza, bidahwitse, kandi bikomeza-kurekura.
