Carboxymethyl cellulose (CMC)yog ib qho anionic cellulose ether tsim los ntawm kev hloov kho tshuaj ntawm cellulose. Nws yog dav siv nyob rau hauv cov khoom noj, tshuaj, tshuaj txhua hnub, roj av, papermaking thiab lwm yam lag luam vim nws zoo thickening, zaj duab xis-forming, emulsifying, suspending thiab moisturizing zog. CMC muaj qib sib txawv. Raws li purity, degree ntawm kev hloov pauv (DS), viscosity thiab cov xwm txheej siv tau, cov qib sib txawv tuaj yeem muab faib ua qib kev lag luam, qib zaub mov thiab qib tshuaj.
1. Muaj qib carboxymethyl cellulose
Muaj qib CMC yog cov khoom siv yooj yim siv dav hauv ntau qhov chaw lag luam. Nws yog tsuas yog siv nyob rau hauv cov roj teb, papermaking, ceramics, textiles, printing thiab dyeing thiab lwm yam lag luam, tshwj xeeb tshaj yog nyob rau hauv kev kho av nkos nyob rau hauv roj extraction thiab reinforcing tus neeg saib xyuas nyob rau hauv daim ntawv ntau lawm.
Viscosity: Cov viscosity ntau ntawm qib kev lag luam CMC yog dav, xws li cov viscosity tsawg mus rau siab viscosity kom tau raws li cov kev xav tau ntawm kev siv sib txawv. High viscosity CMC yog haum rau siv raws li ib tug binder, thaum uas tsis muaj viscosity yog haum rau siv raws li ib tug thickener thiab stabilizer.
Degree ntawm kev hloov pauv (DS): Cov degree ntawm kev hloov pauv ntawm kev lag luam-qib CMC yog qis, txog 0.5-1.2. Qhov qis dua ntawm kev hloov pauv tuaj yeem ua rau kom ceev ntawm CMC yaj hauv dej, tso cai rau nws sai sai tsim cov colloid.
Kev siv thaj chaw:
Roj drilling:CMCyog siv los ua cov thickener thiab tshem tawm cov neeg sawv cev hauv cov av nkos txhawm rau txhim kho cov rheology ntawm cov av nkos thiab tiv thaiv kev tawg ntawm phab ntsa zoo.

Qhov zoo: Muaj-qib CMC muaj tus nqi qis thiab tsim nyog rau kev lag luam loj.
2. Khoom noj khoom haus qib carboxymethyl cellulose
Khoom noj khoom haus-qib CMC yog dav siv hauv kev lag luam khoom noj khoom haus, feem ntau yog cov thickener, emulsifier, stabilizer, thiab lwm yam. Qib no ntawm CMC muaj cov kev xav tau siab rau purity, kev nyiam huv thiab kev nyab xeeb.
Viscosity: Cov viscosity ntawm cov zaub mov-qib CMC feem ntau yog qis rau nruab nrab, feem ntau tswj ntawm 300-3000mPa·s. Qhov tshwj xeeb viscosity yuav raug xaiv raws li daim ntawv thov scenario thiab cov khoom xav tau.
Degree ntawm kev hloov pauv (DS): Qhov kev hloov pauv ntawm cov khoom noj-qib CMC feem ntau tswj ntawm 0.65-0.85, uas tuaj yeem muab cov viscosity nruab nrab thiab zoo solubility.
Kev siv thaj chaw:
Cov khoom siv mis nyuj: CMC yog siv rau hauv cov khoom siv mis nyuj xws li ice cream thiab yogurt kom viscosity thiab saj ntawm cov khoom.
Dej haus: Hauv cov kua txiv hmab txiv ntoo thiab tshuaj yej, CMC tuaj yeem ua qhov kev ncua kev tiv thaiv kom tsis txhob muaj pulp los ntawm kev teeb tsa.
Noodles: Nyob rau hauv noodles thiab mov noodles, CMC tuaj yeem ua kom lub zog thiab saj ntawm noodles, ua rau lawv elastic dua.
Condiments: Nyob rau hauv cov kua ntses thiab zaub xam lav hnav khaub ncaws, CMC ua lub thickener thiab emulsifier los tiv thaiv cov roj-dej sib cais thiab txuas lub neej txee.
Qhov zoo: CMC qib zaub mov ua tau raws li cov qauv kev noj qab haus huv, tsis muaj teeb meem rau tib neeg lub cev, soluble hauv dej txias thiab tuaj yeem tsim cov colloids sai, thiab muaj cov thickening zoo heev thiab ruaj khov.
3. Pharmaceutical-qib carboxymethyl cellulose
Pharmaceutical-qibCMCxav tau cov qauv purity siab dua thiab kev nyab xeeb thiab feem ntau yog siv hauv kev tsim tshuaj thiab khoom siv kho mob. Qib no ntawm CMC yuav tsum ua tau raws li cov qauv tshuaj pharmacopoeia thiab tau txais kev tswj xyuas nruj kom ntseeg tau tias nws tsis muaj tshuaj lom thiab tsis ua rau khaus.
Viscosity: Cov viscosity ntau yam ntawm cov kws tshuaj-qib CMC yog ua kom zoo dua qub, feem ntau ntawm 400-1500mPa·s, kom ntseeg tau tias nws tswj tau thiab ruaj khov hauv kev siv tshuaj thiab kev kho mob.
Degree ntawm kev hloov pauv (DS): Qhov kev hloov pauv ntawm qib tshuaj feem ntau yog nyob nruab nrab ntawm 0.7-1.2 los muab kev tsim nyog solubility thiab stability.
Kev siv thaj chaw:
Kev npaj tshuaj: CMC ua raws li kev sib khi thiab tsis sib haum rau cov ntsiav tshuaj, uas tuaj yeem ua rau cov tawv tawv thiab ruaj khov ntawm cov ntsiav tshuaj, thiab tuaj yeem tawg sai sai hauv lub cev.
Qhov muag tee: CMC ua cov thickener thiab moisturizer rau ophthalmic tshuaj, uas tuaj yeem ua raws li cov khoom ntawm cov kua muag, pab lub qhov muag, thiab txo cov tsos mob ntawm qhov muag qhuav.
