Carboxymethylcellulose (CMC), feem ntau hu ua Cellulose Gum, yog ntau yam thiab dav siv derivative ntawm cellulose. Nws tau txais los ntawm kev hloov kho tshuaj ntawm ntuj cellulose, uas feem ntau yog los ntawm cov ntoo pulp lossis paj rwb. Carboxymethylcellulose pom cov ntawv thov hauv ntau qhov kev lag luam vim nws cov khoom tshwj xeeb xws li dej-soluble polymer. Nov yog qhov tseem ceeb ntawm Carboxymethylcellulose (CMC) lossis Cellulose Gum:

1. Chemical Structure:
   • Carboxymethylcellulose yog muab los ntawm cellulose los ntawm kev qhia cov carboxymethyl pawg mus rau hauv cov pob txha cellulose. Qhov kev hloov kho no txhim kho nws cov dej solubility thiab kev ua haujlwm zoo.
2. Dej Solubility:
   • Ib qho tseem ceeb ntawm CMC yog nws cov dej solubility zoo heev. Nws yooj yim dissolves nyob rau hauv dej los tsim ib tug ntshiab thiab viscous tov.
3. viscosity:
   • CMC muaj nuj nqis rau nws lub peev xwm los hloov kho cov viscosity ntawm aqueous daws. Cov qib sib txawv ntawm CMC muaj, muab ntau yam viscosity qib haum rau ntau daim ntawv thov.
4. Thickening Agent:
   • Hauv kev lag luam khoom noj khoom haus, CMC ua haujlwm ua tus neeg ua haujlwm thickening nyob rau hauv ntau yam khoom xws li kua ntses, hnav khaub ncaws, khoom noj siv mis, thiab cov khoom ci. Nws imparts ib tug ntshaw kev ntxhib los mos thiab sib xws.
5. Stabilizer thiab Emulsifier:
   • CMC ua haujlwm zoo li stabilizer thiab emulsifier hauv cov zaub mov formulations, tiv thaiv kev sib cais thiab txhim khu kev ruaj ntseg ntawm emulsions.
6. Binding Agent:
   • Hauv cov tshuaj, CMC yog siv los ua ib qho kev sib khi hauv cov tshuaj ntsiav tshuaj, pab tuav cov ntsiav tshuaj cov khoom xyaw ua ke.
7. Film-Forming Agent:
   • CMC muaj cov cuab yeej tsim cov yeeb yaj kiab, ua rau nws tsim nyog rau cov ntawv thov uas xav tau ib zaj duab xis nyias, hloov tau yooj yim. Qhov no feem ntau pom nyob rau hauv kev lag luam tshuaj thiab tshuaj pleev ib ce.
8. Drilling Fluids hauv Kev Lag Luam Roj thiab Roj:
   • CMC yog ua hauj lwm hauv cov dej drilling hauv kev lag luam roj thiab roj los tswj cov viscosity thiab cov kua dej poob thaum lub sijhawm ua haujlwm drilling.
9. Cov Khoom Siv Kho Tus Kheej:
   • Hauv cov khoom tu tus kheej xws li tshuaj txhuam hniav, tshuaj zawv plaub hau, thiab tshuaj pleev ib ce, CMC pab txhawb rau cov khoom lag luam ruaj khov, kev ntxhib los mos, thiab kev paub txog tag nrho.
10. Kev lag luam ntawv:
    • CMC yog siv nyob rau hauv daim ntawv kev lag luam los txhim kho daim ntawv lub zog, txhim kho kev tuav cov fillers thiab fibers, thiab ua raws li tus neeg sawv cev sizing.
11. Kev lag luam Textile:
    • Hauv textiles, CMC yog siv los ua cov thickener hauv kev luam ntawv thiab dyeing txheej txheem.
12. Txoj Cai Pom Zoo:
    • Carboxymethylcellulose tau txais kev pom zoo rau kev siv hauv cov khoom noj, tshuaj, thiab ntau yam kev lag luam. Nws feem ntau lees paub tias muaj kev nyab xeeb (GRAS) rau kev noj.

Cov khoom tshwj xeeb thiab kev siv ntawm Carboxymethylcellulose tuaj yeem sib txawv raws li qib thiab kev tsim. Cov neeg tsim khoom muab cov ntaub ntawv cov ntaub ntawv thiab cov txheej txheem los pab cov neeg siv xaiv cov qib tsim nyog rau lawv daim ntawv thov.
