Cov qauv ntawm sodium carboxymethyl cellulose

Methyl celluloseFeem ntau yog lub npe luv ntawm sodium carboxymethyl cellulose, uas yog ib hom polyanionic compound nrog cov dej solubility zoo. Ntawm lawv, methyl cellulose feem ntau suav nrog methyl cellulose m450, hloov kho methyl cellulose, zaub mov qib methyl cellulose, hydroxymethyl cellulose, thiab lwm yam, feem ntau yog siv rau hauv ntau yam kev lag luam, feem ntau siv rau hauv kev tsim kho, ceramics, zaub mov, roj teeb, papermaking, coatings, tshuaj, mining, roj drilling thiab lwm yam kev lag luam. Nws yog ib qho tsim nyog hais tias nyob rau hauv thaj chaw ntawm cement, methylcellulose muaj qhov cuam tshuam pom tseeb rau cov khoom sib xyaw mortar, uas kuj yog vim muaj cov qauv tshwj xeeb ntawm methylcellulose.

Raws li cov cellulose hloov pauv ntev, sodium carboxymethylcellulose nws tus kheej muaj li ntawm 27% ~ 32% ntawm nws cov hydroxyl pawg hauv daim ntawv ntawm methoxy pawg, thiab qib ntawm polymerization ntawm ntau qib ntawmsodium carboxymethylcellulosekuj txawv. Qhov hnyav molecular feem ntau koom nrog yog txij li 10,000 txog 220,000 Da, thiab qib tseem ceeb ntawm kev hloov pauv yog tus lej nruab nrab ntawm cov pab pawg methoxy, uas yog cov chav sib txawv anhydroglucose txuas nrog cov saw hlau.

Sodium carboxymethyl cellulose tam sim no siv dav hauv qee cov tshuaj pleev ib ce, nrog rau cov tshuaj pleev ib ce thiab cov khoom noj khoom haus methyl cellulose, uas feem ntau tsis muaj tshuaj lom, tsis ua rau khaus, thiab tsis ua rau khaus. Methyl cellulose Su yog cov khoom siv tsis muaj calorie,
