Sodium cmc yog dab tsi?

Sodium Carboxymethyl cellulose (CMC) yog dej-soluble polymer muab tau los ntawm cellulose pom muaj nyob hauv cov phab ntsa ntawm tes ntawm cov nroj tsuag. CMC yog tsim los ntawm kev kho cellulose nrog sodium hydroxide thiab monochloroacetic acid, uas ua rau cov khoom siv carboxymethyl (-ch2-npoo.

CMC feem ntau yog siv nyob rau hauv ntau yam kev lag luam, suav nrog cov khoom noj, cov chaw muag tshuaj, kev tu tus kheej, thiab kev siv cov ntaub ntawv, vim nws cov khoom tshwj xeeb. Hauv cov khoom lag luam, sodium cmc ua hauj lwm zoo li tus neeg sawv cev tuab, stabilizer, thiab emulsifier, txhim kho kev ntxhib los mos, txhim kho lub neej, thiab txee lub neej. Hauv cov chaw kuaj tshuaj, nws yog siv los ua cov phau ntawv, ua txhaum, thiab viscosity concorifier hauv ntsiav tshuaj, raug rau, thiab tshuaj pleev. Hauv cov khoom lag luam saib xyuas tus kheej, nws ua haujlwm ua cov tuab dua, moisturizer, thiab zaj duab xis-ua tus neeg sawv cev hauv tshuaj pleev ib ce, tshuaj txhuam, thiab tshuaj txhuam hniav. Hauv cov ntawv thov kev muaj, sodium CMC yog siv los ua phau ntawv, rheology kho kom haum, tshuaj tsuag dej, textiles, thiab roj drilling kua.

Sodium CMC yog qhov zoo tshaj lwm cov ntawv ntawm CMC (xws li calcium cmc lossis potassium cm) vim nws lub siab solubility thiab ruaj khov hauv cov kev daws teeb meem aqueous. Nws muaj nyob rau hauv ntau qib thiab viscosities kom haum rau cov ntawv thov sib txawv thiab kev ua haujlwm. Zuag qhia tag nrho, sodium CMC yog ib qho ntau yam thiab dav siv ntxiv nrog ntau daim ntawv thov thoob plaws kev lag luam ntau haiv neeg thoob plaws kev lag luam ntau haiv neeg thoob plaws ntau haiv neeg.
