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, ayinavumba 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, ayiyi 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%.
