Itandukaniro hagati ya CMC na MHEC

Carboxymethylcellulose (CMC) na Methyl hydroxyethyl selulose (MHEC) ni ubwoko bubiri bukomoka kuri selile bukoreshwa cyane mu nganda zitandukanye. Basangiye bimwe muburyo bwimiterere yimiti nimiterere yumubiri, ariko kandi bafite itandukaniro ryingenzi rituma bikenerwa mubikorwa bitandukanye. Muri iyi nyandiko, tuzasesengura itandukaniro riri hagati ya CMC na MHEC.

Imiterere yimiti
Byombi CMC na MHEC nibikomoka kuri selile ni polymer zishonga amazi. CMC ikomoka kuri selile mu kuyitwara hamwe na aside ya chloroacetike kugirango itangize amatsinda ya carboxymethyl, naho MHEC ikomoka kuri selile mu kuyikorana na okiside ya Ethylene na methyl chloride kugirango itangize amatsinda ya methyl na hydroxyethyl.

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

Viscosity
Byombi CMC na MHEC birashobora kubyimba ibisubizo byamazi no kongera ubwiza. Nyamara, CMC ifite ubukonje burenze MHEC, kandi irashobora gukora geli imeze nka gel iyo ishonga mumazi. Ibi bituma CMC iba nziza gukoreshwa mubisabwa aho hasabwa kubyimba cyangwa geli, nko mu nganda zibiribwa zo gukora isosi no kwambara. Ku rundi ruhande, MHEC, ifite ubukonje buke ugereranije na CMC kandi ubusanzwe ikoreshwa nk'umuhinduzi mwinshi cyangwa uhindura imvugo mu bikorwa aho bisabwa igisubizo gike cyane.

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

Ubushyuhe
CMC na MHEC byombi birahagaze hejuru yubushyuhe butandukanye, ariko hariho itandukaniro mumashanyarazi yabo. CMC ihagaze neza cyane kuruta MHEC 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, MHEC, ifite ubushyuhe buke buri munsi ya CMC kandi irashobora gucika ku bushyuhe bwinshi.

Porogaramu
Byombi CMC na MHEC 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. MHEC isanzwe ikoreshwa nkibyimbye, bihuza, hamwe na rheologiya ihindura mubikorwa byubwubatsi kubicuruzwa nkibara, amarangi, hamwe nibifatika. Irakoreshwa kandi mubikorwa bya farumasi nkibihuza, bidahwitse, kandi bikomeza-kurekura.

Mu gusoza, CMC na MHEC nibikomoka kuri selile ebyiri bisangiye bimwe muburyo bwimiterere yimiti nimiterere yumubiri ariko bifite itandukaniro ritandukanye mubishobora gukemuka, kwijimye, guhagarara kwa pH, guhagarara kwubushyuhe, no kubishyira mubikorwa.
