I-MHEC Hydroxyethyl Methyl Cellulose
CAS:9032-42-2
IHydroxyethyl Methyl Cellulose (MHEC) ama-ethers e-nonionic cellulose ancibilika emanzini, anikezwa njengempushana egelezayo yamahhala noma ngefomu le-granular cellulose.
I-Hydroxyethyl Methyl Cellulose(MHEC) yenziwe nge-cotton-cellulose ehlanzekile kakhulu ngokusabela kwe-etherification ngaphansi kwezimo ze-alkali ngaphandle kwanoma yiziphi izitho zezilwane, amafutha kanye nezinye izakhi ze-bioactive.MHEC ibonakala iyimpushana emhlophe futhi ayinaphunga futhi ayinambitheki.Ibonakala nge-hygroscopicity futhi ayincibiliki kalula emanzini ashisayo, i-acetone, i-ethanol ne-toluene.Emanzini abandayo i-MHEC izokhukhula ibe yisisombululo se-colloidal futhi i-solybility yayo ayithonywa inani le-PH. Ngokufanayo ne-methyl cellulose ngenkathi yengezwa kumaqembu e-Hdroxyethyl.I-MHEC imelana kakhulu nosawoti, incibilika kalula emanzini futhi inokushisa kwejeli okuphezulu.
I-MHEC yaziwa nangokuthi i-HEMC, i-Methyl Hydroxyethyl Cellulose, engasetshenziswa njenge-ejenti yokugcina amanzi esebenza kahle, i-stabilizer, i-adhesives kanye ne-ejenti eyenza ifilimu ekwakhiweni, okunamathiselwe kwamathayela, usimende kanye ne-gypsum esekelwe, okokuhlanza uketshezi, nezinye izinhlelo zokusebenza eziningi.
