Sodium carboxymethyl cellulose qauv

Taw qhia

Carboxymethyl cellulose (CMC) yog ib hom cellulose derivative uas yog muab los ntawm cellulose los ntawm carboxymethylation. Nws yog cov hmoov dawb, tsis muaj ntxhiab, tsis qab, uas yog siv dav hauv cov khoom noj, tshuaj, tshuaj pleev ib ce, thiab lwm yam lag luam. CMC yog cov dej-soluble polymer uas muaj ntau yam kev siv vim nws cov khoom tshwj xeeb. Nws yog siv los ua tus neeg sawv cev thickening, stabilizer, emulsifier, thiab suspending agent. CMC kuj tseem siv los tiv thaiv colloid hauv kev tsim cov ntawv thiab textiles.

Qauv

Cov qauv ntawm carboxymethyl cellulose (CMC) yog tsim los ntawm cov kab sib txuas ntawm cov piam thaj molecules uas txuas ua ke los ntawm glycosidic bonds. Cov piam thaj molecules txuas mus rau ib leeg los ntawm ib qho oxygen atom, tsim cov kab sib txuas. Lub linear saw yog tom qab ntawd carboxymethylated, uas txhais tau hais tias ib pawg carboxymethyl (CH2COOH) txuas rau hydroxyl pawg (OH) ntawm cov piam thaj molecule. Cov txheej txheem carboxymethylation no ua rau lub cev tsis zoo carboxymethyl cellulose molecule.

Cov qauv ntawm carboxymethyl cellulose tuaj yeem sawv cev los ntawm cov qauv hauv qab no:

(C6H10O5)n-CH2COH

qhov twg n yog qhov kev hloov pauv (DS) ntawm pawg carboxymethyl. Qhov degree ntawm kev hloov pauv yog tus naj npawb ntawm carboxymethyl pawg ib cov piam thaj molecule. Qhov siab dua qhov kev hloov pauv, qhov siab dua qhov viscosity ntawm cov tshuaj CMC.

Cov khoom Carboxymethyl cellulose muaj ntau yam khoom tshwj xeeb uas ua rau nws muaj txiaj ntsig zoo rau ntau yam kev siv. Nws yog cov dej-soluble polymer uas ruaj khov heev hauv cov dej daws teeb meem. Nws tseem yog non-toxic, non-irritating, thiab non-allergenic. CMC tseem tiv taus microbial degradation thiab tsis cuam tshuam los ntawm pH lossis kub. CMC yog ib tug muaj zog thickening neeg sawv cev thiab yuav siv tau los thicken ntau yam kua, nrog rau cov zaub mov, tshuaj, thiab tshuaj pleev ib ce. Nws kuj yog siv los ua emulsifier, stabilizer, thiab suspending agent. CMC kuj tseem siv los tiv thaiv colloid hauv kev tsim cov ntawv thiab textiles.
