Sodium cmc yog dab tsi?

Sodium Carboxymethyl Cellulose (CMC) yog ib qho polymer uas yaj tau hauv dej los ntawm cellulose, uas yog ib qho polysaccharide uas tshwm sim ntuj uas pom muaj nyob rau hauv cov phab ntsa cell ntawm cov nroj tsuag. CMC yog tsim los ntawm kev kho cellulose nrog sodium hydroxide thiab monochloroacetic acid, ua rau muaj cov khoom nrog carboxymethyl pawg (-CH2-COOH) txuas rau cellulose backbone.

CMC feem ntau siv rau hauv ntau yam lag luam, suav nrog zaub mov, tshuaj, kev saib xyuas tus kheej, thiab kev siv hauv kev lag luam, vim nws cov khoom tshwj xeeb. Hauv cov khoom noj, sodium CMC ua haujlwm ua tus neeg sawv cev thickening, stabilizer, thiab emulsifier, txhim kho kev ntxhib los mos, kev sib xws, thiab lub txee lub neej. Hauv cov tshuaj, nws yog siv ua tus binder, disintegrant, thiab viscosity modifier hauv cov ntsiav tshuaj, suspensions, thiab tshuaj pleev. Hauv cov khoom saib xyuas tus kheej, nws ua haujlwm ua tus thickener, moisturizer, thiab zaj duab xis-forming tus neeg sawv cev hauv cov tshuaj pleev ib ce, tshuaj pleev, thiab tshuaj txhuam hniav. Hauv kev siv hauv kev lag luam, sodium CMC yog siv ua tus binder, rheology modifier, thiab kua dej tswj kev poob hauv cov xim, cov tshuaj ntxuav tes, textiles, thiab cov roj drilling kua.

Sodium CMC yog qhov nyiam dua li lwm hom CMC (xws li calcium CMC lossis potassium CMC) vim nws cov solubility siab thiab ruaj khov hauv cov kua dej. Nws muaj ntau qib thiab viscosities kom haum rau ntau daim ntawv thov thiab cov kev xav tau ua tiav. Zuag qhia tag nrho, sodium CMC yog cov khoom siv ntau yam thiab siv dav nrog ntau daim ntawv thov thoob plaws ntau yam lag luam.
