Izakhiwo ze-Sodium Carboxymethyl Cellulose
I-CMC iphuma ku-cellulose ene-glucose polymerization degree engu-200-500 kanye ne-etherification degree engu-0.6-0.7.Kuyimpushana emhlophe noma emhlophe noma into ene-fibrous, ayinaphunga futhi i-hygroscopic.Izinga lokushintshwa kweqembu le-carboxyl (izinga le-etherification) linquma izakhiwo zalo.Uma idigri ye-etherification ingaphezu kuka-0.3, iyancibilika kusixazululo se-alkali.I-viscosity yesisombululo esinamanzi inqunywa i-pH kanye nezinga le-polymerization.Uma izinga le-etherification lingu-0.5-0.8, ngeke lihle nge-asidi.I-CMC incibilika kalula emanzini futhi iba yisixazululo se-viscous esisobala emanzini, futhi i-viscosity yayo iyahlukahluka ngokuhlushwa kwesixazululo kanye nezinga lokushisa.Izinga lokushisa lizinzile lingaphansi kuka-60°C, futhi i-viscosity izokwehla lapho ishiselwa isikhathi eside ezingeni lokushisa elingaphezu kuka-80°C.
Ububanzi bokusetshenziswa kwe-sodium carboxymethyl cellulose
Inemisebenzi ehlukahlukene efana nokujiya, ukumisa okwesikhashana, ukufaka i-emulsifying kanye nokusimamisa.Emkhiqizweni wesiphuzo, isetshenziswa kakhulu njenge-thickener yeziphuzo zejusi yohlobo lwe-pulp, njenge-emulsification stabilizer yeziphuzo zamaprotheni kanye nanjenge-stabilizer yeziphuzo ze-yogurt.Umthamo ngokuvamile ngu-0.1% -0.5%.
