EipponCell® MHEC LH 6150MS methyl hydroxyethyl cellulose qhia solubility hauv dej nrog rau qee cov kuab tshuaj organic.Nws nthuav tawm lub peev xwm los yaj hauv dej txias, thiab qhov siab tshaj plaws tau ua tiav nyob ntawm nws cov viscosity.Solubility sib txawv nrog viscosity, nrog qis viscosity sib haum mus rau ntau dua solubility.
MHEC cov khoom yog non-ionic cellulose ethers thiab tsis ua haujlwm li polyelectrolytes.Yog li ntawd, lawv tso saib kev ruaj ntseg nyob rau hauv aqueous daws uas muaj hlau ntsev los yog organic electrolytes.Txawm li cas los xij, ntau ntxiv ntawm electrolytes tuaj yeem ua rau gelation thiab nag lossis daus.
Cov tshuaj aqueous ntawm MHEC cov khoom lag luam muaj cov khoom ua haujlwm saum npoo av, tso cai rau lawv ua haujlwm ua cov tshuaj tiv thaiv colloidal, emulsifiers, thiab dispersants.
Thaum cua sov cov kua dej ntawm MHEC cov khoom mus rau qhov kub thiab txias, nws ua opaque, cov ntaub ntawv gels, thiab precipitates.Txawm li cas los xij, kev ua kom txias tas li rov qab kho cov tshuaj rau nws qhov qub.Qhov kub ntawm qhov gelation thiab nag lossis daus tshwm sim feem ntau yog nyob ntawm qhov muaj cov tshuaj lubricating, tshem tawm cov neeg ua haujlwm, tiv thaiv colloids, emulsifiers, thiab lwm yam.
