Kapangidwe ka sodium carboxymethyl cellulose

Methyl celluloseNthawi zambiri ndi chidule cha sodium carboxymethyl cellulose, yomwe ili yamtundu wa polyanionic wokhala ndi kusungunuka kwamadzi bwino. Pakati pawo, methyl cellulose makamaka zikuphatikizapo methyl mapadi m450, kusinthidwa methyl mapadi, chakudya Gulu methyl cellulose, hydroxymethyl mapadi, etc., amagwiritsidwa ntchito m'mafakitale osiyanasiyana, makamaka ntchito yomanga, ziwiya zadothi, chakudya, mabatire, papermaking, zokutira, mankhwala, kubowola mafuta, migodi ndi zina. Ndikoyenera kutchula kuti m'munda wa simenti, methylcellulose imalepheretsa zosakaniza zamatope, zomwe zimachitikanso chifukwa chapadera cha methylcellulose.

Monga unyolo wautali wolowetsedwa m'malo mwa cellulose, sodium carboxymethyl cellulose yokha ili ndi pafupifupi 27% ~ 32% yamagulu ake a hydroxyl monga magulu a methoxy, ndi digiri ya polymerization yamagulu osiyanasiyana asodium carboxymethylcellulosendi zosiyananso. Kulemera kwa mamolekyu makamaka kumayambira ku 10,000 mpaka 220,000 Da, ndipo digiri yayikulu yoloweza m'malo ndi kuchuluka kwamagulu a methoxy, omwe ndi magawo osiyanasiyana a anhydroglucose olumikizidwa ndi unyolo.

Sodium carboxymethyl cellulose pakali pano imagwiritsidwa ntchito kwambiri pokonzekera zam'mutu, komanso zodzoladzola ndi cellulose ya methyl cellulose, zomwe nthawi zambiri sizikhala zapoizoni, zosalimbikitsa, komanso zosakwiyitsa. Methyl cellulose Su ndi zinthu zopanda caloric,
