Ukunyibilika kweSodium CMC

I-sodium carboxymethyl cellulose (CMC) inyibilika kakhulu emanzini, enye yeempawu zayo eziphambili kwaye inegalelo ekusetyenzisweni kwayo ngokubanzi kumashishini ahlukeneyo. Xa isasazwe emanzini, i-CMC yenza izisombululo ze-viscous okanye iijeli, ngokuxhomekeke kuxinzelelo kunye nobunzima bemolekyuli ye-CMC.

Ukunyibilika kwe-CMC emanzini kuphenjelelwa zizinto ezininzi:

1. I-Degree of Substitution (DS): I-CMC enamaxabiso aphezulu e-DS ithande ukuba nokunyibilika okukhulu kwamanzi ngenxa yokunyuswa kwenani lamaqela e-carboxymethyl angeniswe kwi-cellulose backbone.
2. Ubunzima beMolekyuli: Ubunzima obuphezulu bemolekyuli i-CMC inokubonisa amazinga acothayo okupheliswa xa kuthelekiswa namabanga asezantsi obunzima bemolekyuli. Nangona kunjalo, xa sele inyibilikisiwe, zombini ubunzima bemolekyuli obuphezulu kunye nesezantsi i-CMC zenza izisombululo ezineempawu ezifanayo ze-viscosity.
3. Ubushushu: Ngokubanzi, ukunyibilika kwe-CMC emanzini kunyuka ngobushushu. Amaqondo obushushu aphezulu aququzelela inkqubo yokupheliswa kwaye abangele ukuhanjiswa ngokukhawuleza kwamasuntswana eCMC.
4. I-pH: Ukunyibilika kwe-CMC akuchatshazelwanga yi-pH kuluhlu oluqhelekileyo ekuhlangatyenwe nalo kwizicelo ezininzi. Izisombululo ze-CMC zihlala zizinzile kwaye zinyibilika kuluhlu olubanzi lwe-pH, ukusuka kwi-acidic ukuya kwiimeko zealkaline.
5. Ukuphazamiseka: Ukuphazamiseka okanye ukuxuba kwandisa ukuchithwa kwe-CMC emanzini ngokunyusa uqhagamshelwano phakathi kwamasuntswana e-CMC kunye neamolekyuli zamanzi, ngaloo ndlela kukhawulezisa inkqubo yokufakwa kwamanzi.

I-sodium carboxymethyl cellulose (i-CMC) yaziwa ngokuba yi-solubility egqwesileyo yamanzi, iyenza ibe yongezelelo oluxabisekileyo kwizicelo ezininzi, kubandakanya ukutya, amayeza, iimveliso zokhathalelo lomntu, kunye nokwakhiwa kwamashishini. Ikhono layo lokwenza izisombululo ezizinzileyo kunye ne-viscous zinegalelo ekusebenzeni kwayo njenge-thickener, stabilizer, binder, kunye nefilimu-yangaphambili kwiimveliso ezahlukeneyo kunye neenkqubo.
