MHEC Hydroxyethyl Methyl Cellulose
CAS: 9032-42-2
Hydroxyethyl Methyl Cellulose (MHEC) ndi madzi osungunuka a nonionic cellulose ethers, omwe amaperekedwa ngati ufa waulere kapena mu mawonekedwe a cellulose.
Hydroxyethyl Methyl Cellulose(MHEC) imapangidwa kuchokera ku thonje-cellulose yoyera kwambiri pochita etherification pansi pamikhalidwe ya alkaline popanda ziwalo za nyama, mafuta ndi zina za bioactive.Amawonetsedwa ndi hygroscopicity ndipo samasungunuka m'madzi otentha, acetone, ethanol ndi toluene.M'madzi ozizira MHEC idzaphulika mu njira ya colloidal ndipo kusungunuka kwake sikukhudzidwa ndi mtengo wa PH. Zofanana ndi methyl cellulose pamene zikuwonjezeredwa ku magulu a Hdroxyethyl.MHEC imagonjetsedwa ndi saline, imasungunuka mosavuta m'madzi ndipo imakhala ndi kutentha kwa gel.
MHEC imadziwikanso kuti HEMC, Methyl Hydroxyethyl Cellulose, yomwe ingagwiritsidwe ntchito ngati wothandizira kwambiri posungira madzi, stabilizer, zomatira ndi kupanga mafilimu pomanga, zomatira matailosi, simenti ndi gypsum based plasters, zotsukira zamadzimadzi, ndi ntchito zina zambiri.
