Dab tsi yog sodium cmc?

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

CMC feem ntau siv nyob rau hauv ntau yam lag luam, suav nrog zaub mov, tshuaj, kev saib xyuas tus kheej, thiab kev siv lag luam, vim nws cov khoom tshwj xeeb. Nyob rau hauv cov khoom noj khoom haus, sodium CMC ua hauj lwm raws li ib tug thickening neeg sawv cev, stabilizer, thiab emulsifier, txhim kho kev ntxhib los mos, sib xws, thiab txee lub neej. Hauv cov tshuaj, nws yog siv los ua ib qho kev sib khi, disintegrant, thiab viscosity modifier hauv cov ntsiav tshuaj, ncua kev kawm, thiab tshuaj pleev. Hauv cov khoom siv tu tus kheej, nws ua haujlwm ua cov thickener, moisturizer, thiab zaj duab xis-tsim tus neeg sawv cev hauv tshuaj pleev ib ce, tshuaj pleev, thiab tshuaj txhuam hniav. Hauv cov ntawv thov kev lag luam, sodium CMC yog siv los ua cov ntawv khi, rheology hloov kho, thiab cov kua dej tsis zoo tswj tus neeg saib xyuas hauv cov xim, tshuaj ntxuav tes, textiles, thiab roj drilling kua.

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