Yog CMC ether?

Carboxymethyl cellulose (CMC) tsis yog cellulose ether nyob rau hauv ib txwm muaj. Nws yog ib qho kev sib tw ntawm cellulose, tab sis lo lus "Etaws" tsis yog siv los piav qhia CLC. Hloov chaw, CMC feem ntau raug xa mus ua ib lub cellulose derivative lossis cov hniav ntawm cellulose.

CMC yog tsim los ntawm kev siv cellulation cellulose los ntawm kev qhia ntawm Carboxymethyl pawg mus rau lub cellulose cellebone. Qhov kev hloov kho no imparts dej-solubility thiab ntau txoj haujlwm ntawm cov khoom muaj nuj nqi rau cellulose, ua CMC muaj ntau yam thiab dav siv polymer.

Cov khoom siv tseem ceeb thiab kev siv ntawm Carboxymethyl cellulose (CMC) suav nrog:

1. Dej Solubility:
   • CMC yog cov dej-soluble, sib sau ua kom meej thiab khov kho cov kev daws teeb meem.
2. Thickening thiab ruaj khov:
   • CMC yog siv los ua tus neeg sawv cev tuab hauv ntau qhov kev lag luam, suav nrog cov khoom noj, cov chaw muag tshuaj, thiab tshuaj pleev ib ce, thiab tshuaj pleev ib ce. Nws ruaj ruaj emulsions thiab ncua kev ncua.
3. Dej khaws cia:
   • Hauv kev tsim kho cov khoom, CMC yog siv rau nws cov dej khaws cia, txhim kho cov haujlwm ua haujlwm.
4. Zaj duab xis tsim:
   • CMC tuaj yeem ua cov yeeb yaj kiab nyias, ua kom haum rau cov tshuaj pleev xim, cov nplaum, thiab cov ntawv thov tshuaj.
5. Kev sib tsoo thiab ua kom tawg pov tseg:
   • Hauv cov kws tshuaj, CMC yog siv los ua phau ntawv sau ua qauv thiab ua kev ua txhaum rau cov ntsiav tshuaj xaus.
6. Kev Lag Luam Khoom Noj:
   • CMC tau ua haujlwm raws li cov tuab yaj ntaub, stabilizer, thiab cov kav dej hauv ntau yam khoom noj khoom haus.

Thaum CMC tsis yog xa mus ua lub cellulose ether, nws shares zoo sib xws nrog lwm cov txheej txheem cellulose thiab nws muaj peev xwm hloov kho cov khoom ntawm cellulose rau ntau yam kev siv. Cov qauv tshuaj tshwj xeeb ntawm CMC cuam tshuam cov pawg carboxymethyl txuas rau cov pawg hydroxyl ntawm cov pab pawg ntawm cov cellule.
