Qhov sib txawv tseem ceeb ntawm sodium CMC thiab CMC yog sodium CMC, lossis sodium carboxymethyl cellulose, yooj yim soluble hauv dej kub thiab txias thiab yooj yim khaws cia, qhov CMC, lossis carboxymethyl cellulose, tsis zoo soluble hauv dej. thiab nyuaj khaws cia zoo li nws yog.
Feem ntau, peb tuaj yeem pom carboxymethyl cellulose (CMC) hauv daim ntawv ntawm sodium CMC, uas yog sodium ntsev daim ntawv CMC. Nws hloov mus rau hauv sodium ntsev daim ntawv vim nws cov dej tsis zoo solubility. Sodium CMC muaj cov dej solubility siab, ua kom yooj yim khaws cia.
Sodium CMC yog dab tsi?
Sodium CMC yog sodium carboxymethyl cellulose. Nws yog derivative ntawm CMC. Nws yog ib yam khoom tseem ceeb ntawm cellulose ethers thiab feem ntau yog tsim los ntawm kev hloov kho ntawm ntuj cellulose. Feem ntau, CMC compound muaj cov dej solubility tsis zoo; Yog li ntawd, peb tuaj yeem khaws cia rau hauv daim ntawv ntawm sodium CMC. Cov tshuaj no tseem soluble hauv dej txias, thiab nws muaj dispersibility. Cov yam ntxwv txawv txawv ntawm sodium CMC yog emulsifying dispersion thiab khoom dispersion zog. Nws tuaj yeem piav qhia raws li cov khoom siv ntuj tsim polymer.
Daim duab 01: Qauv ntawm Carboxymethyl Cellulose
Muaj ntau cov ntawv thov tseem ceeb ntawm sodium CMC, suav nrog kev lag luam xws li kev lag luam khoom noj, kev lag luam tshuaj, kev kho hniav, tshuaj, thiab lwm yam. Cov tshuaj macromolecular no tuaj yeem nqus dej thiab o. Thaum o hauv dej, nws tuaj yeem tsim cov kua nplaum tuab. Ntxiv mus, nws yog nruab nrab hauv pH.
Feem ntau, sodium CMC zoo nkaus li cov hmoov dawb mus rau xim daj me ntsis. Nws yog odorless thiab tasteless. Tsis tas li ntawd, nws yog non-toxic thiab yooj yim soluble nyob rau hauv dej kub los yog txias vim muaj sodium ntsev daim ntawv. Nws ruaj khov tiv thaiv lub teeb thiab kub. Txawm li cas los xij, qhov viscosity ntawm qhov sib xyaw no txo qis nrog qhov kub thiab txias.
CMC yog dab tsi?
CMC sawv cev rau carboxymethyl cellulose. Nws tseem hu ua cellulose gum. Peb tuaj yeem txhais tau tias nws yog cellulose derivative muaj carboxymethyl pawg uas tau khi rau qee pawg hydroxyl ntawm glucopyranose monomers hauv cov pob txha cellulose. Feem ntau, qhov sib xyaw no muaj txiaj ntsig zoo hauv nws daim ntawv ntsev ntsev. Peb hu ua sodium CMC. Lub npe lag luam rau qhov sib xyaw no hauv kev ua lag luam yog Tylose.
Daim duab 01: Cov Qauv Tshuaj ntawm CMC
Thaum xav txog kev npaj ntawm CMC compound, peb tuaj yeem ua ke los ntawm alkali-catalyzed cov tshuaj tiv thaiv ntawm cellulose nyob rau hauv muaj chloroacetic acid. Ntawm no, pawg polar carboxyl ua rau solubility ntawm cellulose thiab tshuaj reactivity. Tom qab ua tiav thawj kauj ruam no, cov tshuaj tiv thaiv tshwm sim feem ntau muaj li 60% CMC thiab 40% sodium ntsev xws li sodium chloride thiab sodium glycolate. Peb tuaj yeem piav qhia txog cov khoom sib xyaw no raws li kev CMC, uas muaj txiaj ntsig zoo hauv kev tsim cov tshuaj ntxuav tes. Tom qab ntawd, peb xav tau lwm kauj ruam ua kom huv huv kom tshem tawm cov ntsev sib xyaw thiab ntxuav cov CMC compound. CMC ntshiab no muaj txiaj ntsig zoo hauv kev lag luam zaub mov, kev lag luam tshuaj, thiab kev tsim tshuaj txhuam hniav. Tsis tas li ntawd, muaj cov khoom lag luam semi-purified ib yam nkaus, uas yog ib qho tseem ceeb hauv daim ntawv thov, suav nrog kev kho dua tshiab ntawm cov ntaub ntawv khaws cia.
Muaj ntau daim ntawv thov ntawm CMC, suav nrog kev lag luam khoom noj, qhov twg nws muaj tus lej E E466 lossis E469 (cov ntawv enzymatically hydrolyzed), uas yog qhov muaj txiaj ntsig zoo li lub viscosity modifier thiab ua cov thickener. Tsis tas li ntawd, nws yog ib qho tseem ceeb rau stabilizing emulsions hauv cov khoom xws li ice cream. Tsis tas li ntawd, CMC muaj txiaj ntsig zoo hauv kev tsim cov tshuaj txhuam hniav, tshuaj laxatives, tshuaj noj, tshuaj pleev xim dej, tshuaj ntxuav tes, textile sizing, ntawv khoom, thiab lwm yam.
Qhov txawv ntawm Sodium CMC thiab CMC yog dab tsi?
CMC sawv cev rau carboxymethyl cellulose. Sodium CMC yog sodium ntsev daim ntawv ntawm CMC compound. Qhov sib txawv tseem ceeb ntawm sodium CMC thiab CMC yog tias sodium CMC yog yooj yim soluble hauv dej kub thiab txias; yog li, nws yooj yim khaws cia, qhov CMC tsis zoo soluble hauv dej; yog li ntawd, nws yog ib qho nyuaj rau khaws cia raws li nws yog. Ntxiv mus, CMS yog siv nyob rau hauv kev lag luam khoom noj, tshuaj kev lag luam, kho hniav, tshuaj, thiab lwm yam, whereas sodium CMC yog siv nyob rau hauv kev lag luam khoom noj khoom haus, zus tau tej cov tshuaj txhuam hniav, laxatives, noj tshuaj, tshuaj pleev ib ce, dej-raws li tshuaj, detergents, textile sizing, ntawv. khoom, thiab lwm yam.
Daim duab hauv qab no qhia txog qhov sib txawv ntawm sodium CMC thiab CMC hauv daim ntawv teev npe rau ib sab sib piv.
Summary – Sodium CMC vs CMC
CMC thiab sodium CMC yog cov sib xyaw ua ke. Lub sij hawm CMC sawv cev rau carboxymethyl cellulose. Qhov sib txawv tseem ceeb ntawm sodium CMC thiab CMC yog tias sodium CMC yog yooj yim soluble nyob rau hauv ob qho tib si dej kub thiab txias thiab yog ib qho yooj yim rau khaws cia, whereas CMC yog tsis zoo soluble nyob rau hauv dej thiab yog ib qho nyuaj rau khaws cia raws li nws yog.
