CMC Carboxymethyl Cellulose

Lus piav qhia luv luv:

CAS: 9004-32-4 Nr

Carboxymethyl Cellulose (CMC) yog anionic dej soluble polymer muab tau los ntawm lub ntiaj teb no ntau tshaj polymer - paj rwb cellulose.Nws tseem hu ua cellulose gum, thiab nws sodium ntsev yog ib qho tseem ceeb cellulose derivatives.Cov pawg carboxymethyl khi (-CH2-COOH) raws cov saw hlau polymer ua rau cov cellulose dej-soluble.Thaum yaj, nws tsub kom lub viscosity ntawm aqueous daws, suspensions thiab emulsions, thiab nyob rau hauv ntau dua concentration, nws muab pseudo-plasticity los yog thixotropy.Raws li ib tug natural polyelectrolyte, CMC imparts tus nqi saum npoo rau nruab nrab hais thiab yuav siv tau los txhim kho lub stability ntawm aqueous colloids thiab gels los yog induce agglomeration.Nws muab cov khoom zoo ntawm thickening, dej tuav, zaj duab xis-tsim, rheology thiab lubricity, uas yog dav siv nyob rau hauv cov zaub mov, cov khoom tu tus kheej, muaj xim, ceramics, roj drilling, tsev cov ntaub ntawv thiab lwm yam.

Product Detail

Khoom cim npe

Carboxymethyl cellulose (CMC) yog anionic dej-soluble polymer tau los ntawm cellulose.Nws muaj cov thickening zoo heev, nqus dej, thiab khaws cov dej khaws cia, thiab siv ntau yam kev siv nrog rau cov khoom noj thiab pub additives, tshuaj pleev ib ce, thickening thiab binding agents, binders, dej absorbing cov ntaub ntawv, thiab dej retention agents.Raws li cov khoom yog muab los ntawm tej yam ntuj tso cellulose, nws nthuav gradual biodegradability thiab yuav incinerated tom qab siv, ua rau nws ib tug heev environmentally phooj ywg cov ntaub ntawv.

Solubility ntawm Carboxymethyl Cellulose (CMC)

Carboxymethyl Cellulose (CMC) yog cov tshuaj hydrophilic ntuj thiab thaum sodium carboxymethyl cellulose particles disperse nyob rau hauv dej, nws yuav o tam sim ntawd thiab ces yaj.
1. Nyob rau hauv qhov xwm txheej ntawm nplawm, ntxiv sodium cmc maj mam pab kom nrawm nrawm.
2. Nyob rau hauv cov xwm txheej ntawm cov cua sov, ntxiv sodium cmc dispersedly tuaj yeem ua rau kom muaj kev sib cais, tab sis cov cua kub tsis tuaj yeem siab dhau thiab tsim nyog nyob rau hauv 50-60 ° C.
3. Yog tias nws yog siv los ntawm kev sib xyaw nrog lwm cov ntaub ntawv, ua ntej sib tov cov khib nyiab ua ke thiab tom qab ntawd yaj, thiab ua li no, qhov kev sib cais ceev kuj tuaj yeem txhim kho.
Ntxiv ib yam ntawm cov organic solvents uas yog insoluble nrog sodium cmc tab sis soluble nrog dej xws li ethanol thiab glycerin thiab ces yaj, yog li nyob rau hauv no txoj kev, kev daws teeb meem yuav ceev heev.
