Sodium carboxymethyl cellulose (CMC) yog cov dej-soluble polymer uas yog muab los ntawm cellulose, ib tug natural polysaccharide uas tsim cov qauv ntawm cov nroj tsuag.CMC yog tsim los ntawm kev hloov kho tshuaj ntawm cellulose los ntawm kev sib ntxiv ntawm carboxymethyl pawg (-CH2-COOH) rau nws cov chav tsev anhydroglucose.Cov qib ntawm carboxymethyl hloov pauv tuaj yeem sib txawv, ua rau ntau yam ntawm CMC cov khoom uas muaj cov khoom sib txawv.

CMC feem ntau yog siv los ua cov khoom noj ntxiv, qhov twg nws ua haujlwm ua cov thickener, stabilizer, thiab emulsifier.Nws kuj tseem siv tau rau ntau yam kev lag luam, suav nrog cov tshuaj, tshuaj pleev ib ce, thiab cov khoom tu tus kheej.CMC yog ntau yam thiab muaj txiaj ntsig zoo ntxiv uas muaj ntau yam txiaj ntsig hauv cov ntawv thov no.

Cov khoom ntawmSodium Carboxymethyl Cellulose

Cov khoom ntawm CMC nyob ntawm seb qhov kev hloov pauv ntawm carboxymethyl, uas cuam tshuam rau nws cov solubility, viscosity, thiab lwm yam ntxwv.Feem ntau, CMC yog cov hmoov dawb rau cov xim dawb uas tsis muaj ntxhiab thiab tsis qab.Nws yog heev soluble nyob rau hauv dej thiab cov ntaub ntawv ntshiab, viscous daws.CMC muaj lub peev xwm siab rau kev nqus dej thiab tuaj yeem tsim cov gels thaum hydrated.Nws ruaj khov nyob rau ntau yam ntawm pH qhov tseem ceeb thiab tsis cuam tshuam los ntawm cua sov lossis enzyme degradation.

Lub viscosity ntawm CMC cov kev daws teeb meem txawv nyob ntawm seb qhov kev hloov pauv thiab qhov concentration ntawm cov tshuaj.Cov qib qis ntawm kev hloov pauv ua rau cov viscosity qis dua, thaum qib siab dua ntawm kev hloov pauv ua rau cov viscosity ntau dua.Lub viscosity ntawm CMC cov kev daws teeb meem kuj tuaj yeem cuam tshuam los ntawm qhov kub thiab txias, pH, thiab muaj lwm cov kuab tshuaj.

Kev siv ntawm Sodium Carboxymethyl Cellulose

1. Kev lag luam zaub mov

Hauv kev lag luam khoom noj khoom haus, CMC yog dav siv los ua cov thickener, stabilizer, thiab emulsifier hauv ntau yam khoom, nrog rau cov khoom ci, khoom noj siv mis, dej haus, thiab cov nqaij ua tiav.CMC pab txhim kho kev ntxhib los mos, sib xws, thiab txee lub neej ntawm cov khoom no.Piv txwv li, hauv cov dej khov nab kuab, CMC pab tiv thaiv cov dej khov nab kuab los ntawm kev tsim, ua rau muaj kev ntxhib los mos.Hauv cov nqaij ua tiav, CMC pab txhim kho cov dej tuav thiab tiv thaiv kev sib cais ntawm cov rog thiab dej.

2. Kev lag luam kws tshuaj

Hauv kev lag luam kws tshuaj, CMC yog siv los ua ib qho kev sib khi, disintegrant, thiab ntsiav tshuaj txheej tus neeg sawv cev.Nws pab txhim kho cov khoom ntws ntawm cov hmoov thiab granules thiab ua kom cov khoom sib xyaw ua ke ntawm cov khoom xyaw nquag.CMC kuj tseem siv los ua tus neeg sawv cev tshem tawm hauv cov tshuaj ua kua thiab ua cov roj nplua nyeem hauv cov tshuaj ntsiav.

3. Kev lag luam tshuaj pleev ib ce thiab kho tus kheej

Hauv kev lag luam tshuaj pleev ib ce thiab kev tu tus kheej, CMC yog siv los ua cov thickener, emulsifier, thiab stabilizer hauv cov khoom xws li tshuaj pleev, tshuaj zawv plaub hau, thiab tshuaj txhuam hniav.CMC pab txhim kho kev ntxhib los mos, ruaj khov, thiab zoo li ntawm cov khoom no.Piv txwv li, nyob rau hauv cov tshuaj txhuam hniav, CMC pab kom tuab cov muab tshuaj txhuam thiab txhim kho nws adhesion rau cov hniav.

4. Lwm Daim Ntawv Thov

CMC muaj ntau lwm daim ntawv thov, suav nrog hauv kev lag luam ntawv, qhov chaw uas nws yog siv los ua cov txheej thiab sizing tus neeg sawv cev, thiab hauv kev lag luam textile, qhov twg nws yog siv los ua thickener thiab sizing tus neeg saib xyuas rau fabrics.CMC kuj tseem siv rau hauv cov roj drilling kua, qhov uas nws pab tswj viscosity thiab kua poob.

Cov txiaj ntsig ntawm Sodium Carboxymethyl Cellulose

1. Ntau yam

CMC yog cov khoom siv ntau yam ntxiv uas tuaj yeem siv rau ntau yam kev siv, suav nrog zaub mov, tshuaj, tshuaj pleev ib ce, thiab cov khoom tu tus kheej.Nws muaj peev xwm ua haujlwm ua cov thickener, stabilizer, thiab emulsifier ua rau nws muaj txiaj ntsig zoo hauv ntau cov qauv.

2. Kev nyab xeeb

CMC yog suav tias yog khoom noj khoom haus muaj kev nyab xeeb los ntawm cov koom haum tswj hwm xws li FDA thiab EFSA.Nws tau raug kuaj xyuas ntau yam kev nyab xeeb thiab tau pom tias tsis muaj tshuaj lom thiab tsis muaj carcinogenic.
