    I-CAS 9032-42-2 HEMC yemilutha yokwakha

    1. I-HEMC hydroxyethyl methyl cellulose yenziwa nge-highly pure cotton cellulose. Ngemuva kokwelashwa kwe-alkali kanye ne-etherification ekhethekile iba yi-HEMC. Ayinamafutha ezilwane nezinye izinto ezisebenzayo.

    2. Ukubukeka kwe-HEMC kuyizinhlayiya ezimhlophe noma i-powder, ayinaphunga futhi ayinambitheki. I-hygroscopic futhi ayikwazi ukuncibilika emanzini ashisayo, i-acetone. i-ethanol ne-toluene. Ngemuva kokuvuvukala emanzini abandayo kusixazululo se-colloidal, ukuncibilika akuthinteki inani le-PH. Iyafana ne-methyl cellulose, kepha ngokwanda kwamaqembu e-hydroxyethyl, inokubekezelelana okuningi, incibilika kalula emanzini futhi inezinga lokushisa eliphakeme kakhulu.
