Properties ntawm Methyl Cellulose

Methyl cellulose (MC) yog ib qho cellulose ether uas muaj ntau yam kev siv hauv ntau yam lag luam, suav nrog zaub mov, tshuaj, thiab kev tsim kho. Qee qhov khoom ntawm MC suav nrog:

1. Solubility: MC yog soluble hauv dej thiab tuaj yeem tsim cov tshuaj ntshiab thiab ruaj khov ntawm chav sov. Nws kuj yog soluble hauv qee cov kuab tshuaj organic, xws li ethanol thiab methanol.
2. Viscosity: Lub viscosity ntawm MC cov kev daws teeb meem yog nyob ntawm ntau yam, suav nrog qib kev hloov pauv, qhov hnyav molecular, thiab qhov concentration ntawm MC cov tshuaj. MC cov kev daws teeb meem nthuav tawm tus cwj pwm tsis yog-Newtonian ntws, txhais tau tias cov viscosity hloov nrog tus nqi shear.
3. Zaj duab xis-forming: MC tuaj yeem tsim ib zaj duab xis thaum nws yaj hauv dej thiab qhuav. Cov yeeb yaj kiab tsim los ntawm MC yog hloov tau, pob tshab, thiab muaj cov khoom thaiv zoo.
4. Thermal stability: MC muaj thermal stability zoo thiab tuaj yeem tiv taus kub txog 200 ° C yam tsis muaj kev puas tsuaj loj.
5. Compatibility: MC yog sib xws nrog ntau lwm yam ntaub ntawv, nrog rau lwm yam cellulose ethers, starch, thiab proteins.
6. Hydrophilicity: MC yog hydrophilic heev, txhais tau tias nws muaj kev sib raug zoo rau dej. Cov cuab yeej no ua rau MC muaj txiaj ntsig hauv cov qauv uas khaws cov dej tseem ceeb, xws li hauv cov khoom noj thiab cov khoom tu tus kheej.

Zuag qhia tag nrho, cov khoom ntawm MC ua rau nws muaj ntau yam khoom siv uas tuaj yeem siv tau ntau yam kev siv.
