Cov qauv ntawm sodium carboxymethyl cellulose

Methyl celluloseFeem ntau yog cov ntawv luv ntawm sodium carboxymethyl cellulose, uas belongs rau ib hom polyanionic compound nrog 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 qhov kev lag luam, feem ntau yog siv hauv kev tsim kho, ceramics, khoom noj khoom haus, roj teeb, papermaking, coatings, pharmaceuticals, drilling thiab lwm yam mining. Nws yog tsim nyog hais tias nyob rau hauv lub tshav pob ntawm cement, methylcellulose muaj ib tug pom tseeb retarding nyhuv ntawm mortar mixs, uas yog vim li cas tus qauv ntawm methylcellulose.

Raws li cov saw ntev hloov cellulose, sodium carboxymethylcellulose nws tus kheej muaj li ntawm 27% ~ 32% ntawm nws pawg hydroxyl nyob rau hauv daim ntawv ntawm methoxy pawg, thiab cov degree ntawm polymerization ntawm ntau qib ntawmsodium carboxymethyl cellulosekuj txawv. Qhov hnyav molecular feem ntau cuam tshuam los ntawm 10,000 txog 220,000 Da, thiab qhov tseem ceeb ntawm kev hloov pauv yog qhov nruab nrab ntawm cov methoxy pawg, uas yog txawv anhydroglucose units txuas nrog cov saw hlau.

Sodium carboxymethyl cellulose tam sim no tau siv dav hauv qee cov tshuaj pleev ib ce, nrog rau cov tshuaj pleev ib ce thiab zaub mov qib methyl cellulose, uas feem ntau tsis muaj tshuaj lom, tsis hnov ​​​​tsw, thiab tsis khaus. Methyl cellulose Su yog cov khoom tsis muaj calorie,
