Cov khoom ntawm Sodium Carboxymethyl Cellulose

Sodium carboxymethyl cellulose (NaCMC) yog cov dej-soluble polymer muab tau los ntawm cellulose. Nws muaj ntau yam khoom siv lub cev thiab tshuaj lom neeg uas ua rau nws muaj txiaj ntsig zoo hauv ntau hom kev lag luam. Nov yog qee qhov tseem ceeb ntawm NaCMC:

1. Dej solubility: NaCMC yog soluble hauv dej heev thiab tuaj yeem tsim cov kua dej ntshiab thiab khov.
2. Rheology: NaCMC nthuav tawm tus cwj pwm shear-thinning, uas txhais tau hais tias nws cov viscosity txo qis raws li tus nqi shear nce. Cov cuab yeej no ua rau nws muaj txiaj ntsig zoo li thickener thiab stabilizer hauv ntau daim ntawv thov.
3. pH stability: NaCMC ruaj khov nyob rau ntau yam ntawm pH qhov tseem ceeb, los ntawm acidic mus rau alkaline.
4. Lub zog Ionic: NaCMC yog qhov nkag siab rau lub zog ionic thiab tuaj yeem siv los ua kom tuab thiab ruaj khov cov kev daws teeb meem uas muaj ntau yam ions.
5. Thermal stability: NaCMC ruaj khov ntawm qhov kub thiab txias thiab tuaj yeem siv rau hauv cov ntawv thov uas yuav tsum tau ua kom sov.
6. Kev muaj peev xwm ua yeeb yaj kiab: NaCMC tuaj yeem tsim cov yeeb yaj kiab nyias, pob tshab, thiab hloov tau yooj yim thaum ziab. Cov cuab yeej no ua rau nws muaj txiaj ntsig zoo hauv kev siv xws li txheej, zaj duab xis, thiab cov nplaum.
7. Biodegradability: NaCMC yog biodegradable polymer, uas txhais tau hais tias nws tuaj yeem tawg los ntawm cov kab mob hauv ib puag ncig.

Zuag qhia tag nrho, NaCMC muaj kev sib xyaw tshwj xeeb ntawm cov khoom uas ua rau nws muaj txiaj ntsig zoo hauv ntau yam kev siv, suav nrog zaub mov, tshuaj, tshuaj pleev ib ce, thiab ntau daim ntawv thov kev lag luam. Nws lub peev xwm los tsim cov kev daws teeb meem, nws cov pH ruaj khov, thiab nws lub peev xwm ua yeeb yaj kiab ua rau nws muaj txiaj ntsig zoo hauv ntau cov khoom.
