    I-CAS 9032-42-2 HEMC yokwakha iziyobisi

    1. I-HEMC hydroxyethyl methyl cellulose yenziwa kwi-cellulose ecocekileyo yomqhaphu. Emva konyango lwealkali kunye ne-etherification ekhethekileyo iba yi-HEMC. Ayinawo nawaphi na amafutha ezilwanyana kunye nezinye izinto ezisebenzayo.

    2. Imbonakalo ye-HEMC ngamasuntswana amhlophe okanye umgubo, awunantsingiselo kwaye awunancasa. I-hygroscopic kwaye ayinakunyibilika emanzini ashushu, i-acetone. i-ethanol kunye ne-toluene. Emva kokudumba emanzini abandayo kwisisombululo se-colloidal, ukunyibilika akuchaphazeleka lixabiso le-PH. Kuyafana ne-methyl cellulose, kodwa ngokunyuka kwamaqela e-hydroxyethyl, inokunyamezelana ngakumbi, inyibilika ngokulula emanzini kwaye ineqondo lobushushu eliphezulu lokuncipha.
