Cov yam ntxwv ntawm CMC

Carboxymethyl cellulose (CMC) yog ib qho khoom plig uas muaj ntau yam los ntawm cellulose, muaj ob peb tus yam ntxwv tshwj xeeb uas ua rau nws siv dav hauv ntau yam kev lag luam. Ntawm no yog cov yam ntxwv tseem ceeb ntawm CMC:

1. Dej solubility: CMC yog soluble heev hauv dej, sib sau meej, viscous daws teeb meem. Cov cuab yeej no tso cai rau kev sib txuam yooj yim rau hauv aqueous formulations, ua rau nws haum rau siv nyob rau hauv ntau cov ntawv thov.
2. Cov neeg saib xyuas tuab: CMC ua raws li cov neeg sawv cev ua kom zoo, nce viscosity ntawm cov kua aqueous thiab ncua kev ncua. Nws imparts kev ntxhib los mos thiab lub cev rau cov khoom lag luam, txhim kho lawv cov kev ruaj khov thiab kev ua tau zoo.
3. Pseudoprasticity: CMC Cov Khoom Taw Qhia Pseudopastic cwj pwm, txhais tau tias nws viscosity txo qis nrog nce shear tus nqi. Cov cuab yeej no tso cai rau kev ua haujlwm yooj yim, sib xyaw, thiab cov ntawv thov ntawm CMC-muaj cov khoom lag luam, thaum muab cov khoom ruaj khov thaum sawv.
4. Zaj duab xis-tsim: CMC muaj zaj duab xis-ua yeeb yaj kiab, cia nws tsim cov pob tshab, cov yeeb yaj kiab siv tau thaum qhuav. Cov xeeb ceem no ua rau nws muaj txiaj ntsig hauv kev thov uas tiv thaiv cov yeeb yaj kiab lossis cov duab teeb meem, xws li ntim cov khoom noj, thiab ntim khoom noj.
5. Kev tuav tus neeg saib xyuas: CMC ua raws li phau ntawv qhia nyob rau hauv ntau yam kev siv, yooj yim rau cohesion ntawm cov lus lossis cov formers hauv cov qauv. Nws txhim kho lub zog thiab kev ncaj ncees ntawm cov khoom lag luam, txhim kho lawv qhov kev ua tau zoo thiab kav ntev.
6. Stabilizer: CMC pabcuam ua lub stabilizer, tiv thaiv kev daws teeb lossis sib cais ntawm cov lus hauv ncua lossis emulsions. Nws pab tswj cov kev sib xws thiab homogeneity ntawm cov khoom lag luam, ua kom zoo ib yam zoo nyob rau lub sijhawm.
7. Dej khaws cia: CMC muaj cov dej ua tau zoo heev, tso cai rau nws tuav dej thiab tiv thaiv kom tsis txhob muaj cov qauv zoo. Cov cuab yeej no tau txais txiaj ntsig zoo hauv cov ntawv thov uas noo noo tswj yog qhov tseem ceeb, xws li hauv cov khoom siv thiab cov khoom lag luam.
8. Ionic cov yam ntxwv: CMC muaj cov pab pawg carboxyl uas tuaj yeem ionize hauv dej, muab nws anionic cov khoom. Qhov no tso cai rau CMC los cuam tshuam nrog lwm tus them nyiaj los yog thaj chaw, ua rau nws cov thickening, ruaj khov, thiab kev siv lub peev xwm khi.
9. PH kev ruaj khov: cmc yog ruaj khov tshaj li qhov dav ntev, los ntawm acidic rau alkaline tej yam kev mob. Cov versatility no tso cai rau nws cov kev siv hauv cov qauv nrog cov qib thib ob yam tsis muaj kev cuam tshuam loj lossis poob ntawm kev ua haujlwm.
10. Biodegradabe: CMC yog muab tau los ntawm cov chaw muaj xyoob ntoo thiab yog biodegradable nyob rau hauv txoj cai tsim nyog. Nws tawg rau hauv kev tsis muaj mob los ntawm cov khoom lag luam, ua rau nws ib puag ncig tus phooj ywg thiab muaj kev cia siab.

Cov yam ntxwv ntawm CMC ua nws muaj txiaj ntsig ntxiv hauv ntau yam kev lag luam, suav nrog cov khoom noj, cov chaw tu tshuaj, cov kws saib xyuas tus kheej, ntawv, thiab kev tsim kho. Nws vagasatility, kua solubility, muaj peev xwm ua kom tuab, thiab ua yeeb yaj kiab zaj duab xis ua rau nws siv thiab kev siv versatility ntau thiab kev siv versatility.
