Kapangidwe ka sodium carboxymethyl cellulose

Methyl celluloseKawirikawiri ndi chidule cha sodium carboxymethyl cellulose, chomwe chili m'gulu la polyanionic compound yokhala ndi madzi abwino osungunuka. Pakati pawo, methyl cellulose makamaka imaphatikizapo methyl cellulose m450, modified methyl cellulose, food grade methyl cellulose, hydroxymethyl cellulose, ndi zina zotero, nthawi zambiri amagwiritsidwa ntchito m'mafakitale osiyanasiyana, makamaka pomanga, zoumba, chakudya, mabatire, kupanga mapepala, zokutira, mankhwala, migodi, kuboola mafuta ndi mafakitale ena. Ndikoyenera kunena kuti pankhani ya simenti, methylcellulose imakhala ndi mphamvu yochepetsera kusakaniza kwa matope, zomwe zimachitikanso chifukwa cha kapangidwe kake kapadera ka methylcellulose.

Monga cellulose yosinthidwa ndi unyolo wautali, sodium carboxymethylcellulose yokha ili ndi pafupifupi 27% ~ 32% ya magulu ake a hydroxyl mu mawonekedwe a magulu a methoxy, ndi mlingo wa polymerization wa mitundu yosiyanasiyana yasodium carboxymethylcellulosendi yosiyananso. Kulemera kwa mamolekyu komwe kumakhudzidwa makamaka kumakhala pakati pa 10,000 ndi 220,000 Da, ndipo digiri yayikulu yosinthira ndi kuchuluka kwapakati kwa magulu a methoxy, omwe ndi mayunitsi osiyanasiyana a anhydroglucose olumikizidwa ku unyolo.

Sodium carboxymethyl cellulose imagwiritsidwa ntchito kwambiri popanga zinthu zina zodzikongoletsera, komanso zodzoladzola ndi methyl cellulose ya chakudya, zomwe nthawi zambiri sizikhala ndi poizoni, sizimayambitsa kukwiya, komanso sizimayambitsa mkwiyo. Methyl cellulose Su ndi chinthu chosakhala ndi ma calories,
