Iipropati zeSodium Carboxymethyl Cellulose
I-CMC yi-cellulose derivative ene-glucose polymerization degree ye-200-500 kunye ne-etherification degree ye-0.6-0.7. Ingumgubo omhlophe okanye omhlophe okanye i-fibrous substance, engenavumba kunye ne-hygroscopic. Iqondo lokutshintshwa kweqela le-carboxyl (iqondo le-etherification) limisela iimpawu zalo. Xa isidanga se-etherification singaphezulu kwe-0.3, sinyibilika kwisisombululo sealkali. I-viscosity yesisombululo samanzi inqunywe yi-pH kunye neqondo le-polymerization. Xa iqondo le-etherification liyi-0.5-0.8, aliyi kudlula kwi-asidi. I-CMC inyibilika ngokulula emanzini kwaye ibe sisisombululo se-viscous esobala emanzini, kwaye i-viscosity yayo iyahluka kunye noxinzelelo lwesisombululo kunye nobushushu. Iqondo lokushisa lizinzile ngaphantsi kwe-60 ° C, kwaye i-viscosity iya kuncipha xa ishushu ixesha elide kwiqondo lokushisa elingaphezu kwama-80 ° C.
Ubungakanani bokusetyenziswa kwe-sodium carboxymethyl cellulose
Inemisebenzi eyahlukeneyo enjengokuqina, ukumisa, ukumilisela kunye nokuzinzisa. Kwimveliso yesiselo, isetyenziswa ikakhulu njengento ejiyileyo kwiziselo zejusi yohlobo lwepulp, njenge-emulsification stabilizer kwiziselo zeprotheyini kunye nanjengezinzisi kwiziselo zeyogathi. Idosi ngokubanzi yi-0.1% -0.5%.
