Hydroxyethyl Methyl Cellulose (HEMC)

  • MHEC Hydroxyethyl Methyl Cellulose

    MHEC Hydroxyethyl Methyl Cellulose

    CAS:9032-42-2

    Ko te Hydroxyethyl Methyl Cellulose (MHEC) he wairewa wairewa nonionic cellulose ethers, he mea tuku hei paura rere kore utu, i roto ranei i te cellulose ahua kirikiri.

    Ko te Hydroxyethyl Methyl Cellulose(MHEC) he mea hanga mai i te miro-cellulose tino parakore na roto i te tauhohenga o te etherification i raro i nga tikanga kawakore kaore he whekau o nga kararehe, ngako me etahi atu waahanga koiora. Ko te ahua o te MHEC he paura ma, he hongi me te kore reka.Ka whakaatuhia e te hygroscopicity me te whakauaua i te wairewa i roto i te wai wera, te acetone, te waihano me te toluene.I roto i te wai matao ka pupuhi te MHEC ki te wairewa colloidal, karekau e awehia tona solybility e te uara PH. He rite ki te methyl cellulose i te wa e tapirihia ana ki nga roopu Hdroxyethyl.He kaha ake a MHEC ki te tote, he ngawari ki te wairewa ki te wai, he teitei ake te pāmahana reera.

    Kei te mohiotia ano a MHEC he HEMC, Methyl Hydroxyethyl Cellulose, ka taea te whakamahi hei kaihoko pupuri wai tino pai, te whakapumau, te whakapiri me te kaihoko hanga kiriata i roto i te hanga, te whakapiri taera, te raima me te raima i runga i te raima, te horoi wai, me te maha atu o nga tono.
