Kusungunuka kwa sodium CMC

Sodium carboxymethyl cellulose (CMC) imasungunuka kwambiri m'madzi, yomwe ndi imodzi mwazinthu zake zazikulu ndipo imathandizira kuti igwiritsidwe ntchito m'mafakitale osiyanasiyana. Ikamwazika m'madzi, CMC imapanga mayankho a viscous kapena gels, kutengera kuchuluka kwa ma cell a CMC.

Kusungunuka kwa CMC m'madzi kumatengera zinthu zingapo:

1. Degree of Substitution (DS): CMC yokhala ndi ma DS apamwamba amakhala ndi kusungunuka kwamadzi kwakukulu chifukwa cha kuchuluka kwa magulu a carboxymethyl omwe amalowetsedwa pamsana wa cellulose.
2. Kulemera kwa Mamolekyulu: Kulemera kwa mamolekyulu a CMC kumatha kuwonetsa kuchepa kwapang'onopang'ono poyerekeza ndi magiredi otsika a maselo. Komabe, ikasungunuka, onse apamwamba ndi otsika maselo olemera a CMC amakhala ndi mayankho okhala ndi mawonekedwe ofanana.
3. Kutentha: Nthawi zambiri, kusungunuka kwa CMC m'madzi kumawonjezeka ndi kutentha. Kutentha kwapamwamba kumathandizira kusungunuka ndipo kumapangitsa kuti tinthu tating'onoting'ono ta CMC tifike mwachangu.
4. pH: Kusungunuka kwa CMC sikumakhudzidwa ndi pH mkati mwamitundu yomwe imakumana ndi ntchito zambiri. Mayankho a CMC amakhalabe okhazikika komanso osungunuka pamitundu yambiri ya pH, kuchokera ku acidic kupita ku zinthu zamchere.
5. Kusokonezeka: Kusokonezeka kapena kusanganikirana kumawonjezera kusungunuka kwa CMC m'madzi powonjezera kulumikizana pakati pa tinthu tating'ono ta CMC ndi mamolekyu amadzi, motero kumathandizira kuti ma hydration azitha.

sodium carboxymethyl cellulose (CMC) imadziwika kuti imasungunuka bwino kwambiri m'madzi, ndikupangitsa kuti ikhale yowonjezera pamitundu yambiri yogwiritsira ntchito, kuphatikizapo chakudya, mankhwala, mankhwala osamalira anthu, ndi mapangidwe a mafakitale. Kutha kwake kupanga mayankho okhazikika komanso owoneka bwino kumathandizira kuti igwire ntchito ngati thickener, stabilizer, binder, ndi film-former muzinthu zosiyanasiyana.
