Hydroxyethyl Methyl Cellulose (MHEC) ke metsi a qhibilihang ka nonionic cellulose ethers, a fanoang e le phofo e phallang e sa lefelloeng kapa ka sebōpeho sa granular cellulose.
Hydroxyethyl Methyl Cellulose(MHEC) e entsoe ka k'hothone-cellulose e hloekileng haholo ka ho itšoara ha etherification tlas'a maemo a alkaline ntle le litho leha e le life tsa liphoofolo, mafura le likarolo tse ling tsa bioactive.MHEC e bonahala e le phofo e tšoeu 'me ha e na monko ebile ha e na tatso.E hlahisoa ke hygroscopicity mme ha e khone ho qhibiliha ka metsing a chesang, acetone, ethanol le toluene.Metsing a batang MHEC e tla ruruha ka tharollo ea colloidal 'me solybility ea eona ha e susumetsoe ke bohlokoa ba PH. Ho tšoana le methyl cellulose ha e ntse e kenngoa ho lihlopha tsa Hdroxyethyl.MHEC e hanyetsana le letsoai, e qhibiliha habonolo metsing 'me e na le mocheso o phahameng oa gel.
MHEC e boetse e tsejoa e le HEMC, Methyl Hydroxyethyl Cellulose, e ka sebelisoang e le sesebelisoa sa ho boloka metsi se sebetsang hantle, se tsitsitseng, sekhomaretsi le se etsang filimi kahong, likhomaretsi tsa lithaele, samente le li-plaster tse thehiloeng ho gypsum, sesepa sa metsi le lits'ebetso tse ling tse ngata.
