Hydroxyethyl cellulose (HEC) thiab Carboxymethyl cellulose derivose, ncua kev siv tshuaj thiab cov khoom siv tau sib txawv me ntsis. txawv.
Hydroxyethyl cellulose tau txais los ntawm reodium hydium hydroxide thiab Ashyl Hydroxide. Nws muaj cov khoom siv solubility zoo thiab rheological cov khoom thiab yog siv dav hauv txheej txheem txheej, tshuaj pleev ib ce thiab tshuaj tshuaj paus. Nws lub ntsiab tseem ceeb yog nws cov muaj zog ruaj khov rau qhov kub hloov thiab nws lub peev xwm los nyob ruaj khov nyob rau hauv cov dav dav.
Carboxymethylcellulose, ntawm qhov tod tes, yog tsim los ntawm celling cellulose nrog corporoacetic acid thiab muaj peev xwm carboncosity thiab muaj peev xwm los ua cov gels. CMC feem ntau yog siv nyob rau hauv cov chaw ua noj, tshuaj, thiab tshuaj pleev ib ce, tshwj xeeb yog cov ntaub pua plag thiab stabilizer nyob hauv cov zaub mov.
HEC thiab CMC muaj qhov sib txawv tseem ceeb hauv cov qauv tshuaj, solubility, viscosity thiab teb teb. Yam khoom twg los xaiv nyob ntawm qhov kev xav tau siv tshwj xeeb thiab kev ua tau zoo.
