HEMC LH 6000

Ko te EipponCell® HEMC LH 6000 hydroxyethyl methyl cellulose he katote-kore-a-roto i konatunatua etera i hangaia ma te tukanga matū e whai ana i te miro, te rakau kawakore, te ethylene oxide, me te methyl chloride ether.I tenei wa, ka taea te wehewehe i te tukanga whakaputa o HEMC ki nga tikanga matua e rua: te tikanga waahanga wai me te tikanga hau.I roto i te tikanga wahanga wai, ko nga taputapu e whakamahia ana he iti nga whakaritenga pehanga o roto, ka iti ake te tupono.Ka rukuhia te cellulose ki roto i te rei, ka hua te pupuhi me te waikore.Ko te pupuhi osmotic o te wai ka whai hua ki te cellulose, ka puta nga hua HEMC me te ahua o te ahua o te whakakapinga me te pokey.I tua atu, ko te tikanga waahanga wai ka taea te whakakapi ngawari ki nga momo momo hua.Heoi, he iti te kaha o te hanga o te reactor (te nuinga kei raro iho i te 15m3), na reira e tika ana kia nui ake te maha o nga reactors mo te hanga teitei ake.I tua atu, ko te tukanga tauhohenga he nui te nui o te whakarewa pararopi hei kaikawe, ka roa ake te wa tauhohenga (te nuinga o te 10 haora), te piki ake o te whakaora whakarewa whakarewa, me te utu nui ake.I tetahi atu taha, ko te tikanga hau-waahanga he taputapu kiato me te tuku i nga hua o te puranga kotahi.Ka puta te tauhohenga i roto i te autoclave whakapae, he poto ake te wa tauhohenga (te tikanga 5-8 haora) ka whakaritea ki te tikanga wahanga wai.Ko tenei tikanga kaore e hiahiatia he punaha whakaora whakarewa matatini.I muri i te otinga o te tauhohenga, ka hangaruatia te taikaha o te methyl chloride me te hua-a-hua dimethyl ether ka whakamahia wehea ma te punaha whakaora.Ko te tikanga hau-waahanga he iti ake nga utu mo te mahi me te whakaheke i te kaha o te mahi, ka iti ake nga utu whakangao ka whakaritea ki te tikanga wahanga wai.Heoi, ko te tikanga hau-waahanga me whai haumi nui ki nga taputapu me te whakahaere aunoa, ka piki ake nga ihirangi hangarau me nga utu e pa ana. Kei hea te hoko Cas HEMC LH 6000

Te tono mo te HEMC LH 6000

Ko te EipponCell® HEMC LH 6000 Cellulose ether he taapiri taapiri e whakamahia ana i roto i te kumete whakamaarama wera.Ko tana whakauru ki roto i te hanganga moata he tino paanga ki te whakamaroketanga o te rauemi.He mea whakamiharo, i te mea ka piki ake te ihirangi o te hydroxyethyl methylcellulose, ka heke te whakamaroke i te tuatahi ka piki ake.Ko nga uara whakaheke iti me te teitei ka kitea i te 2.4% me te 3% te ihirangi, ia.

Waihoki, he rite ano te ahua o te moata whakamaroke waiariki pararopi mo te mate papatipu me te whakamaroketanga me te taapiri o te cellulose ether.Ka heke te mate papatipu i te tuatahi, ka eke ki te iti rawa ki te 3% te ihirangi, engari ka piki ake me te piki haere o te cellulose ether.Ko te mea nui, ko te mate papatipu me te whakamaroketanga karekau i te hono tika.

Ko te taapiri o te hydroxyethyl methylcellulose he pai te paanga ki te tohatoha rahi o te pore i roto i te kumete whakamaarama wera.He maha nga tihi ka puta i roto i nga rahi pore i raro i te 5nm me te 10nm, e arai ana ki te ahua o te heke tuatahi ka piki ake te rahi o te pore i raro i te 10nm i te piki haere o te ihirangi cellulose ether.Ka tae te inenga o te cellulose ether ki te 3%, ko te diameter pore o te iti iho i te 10nm he teitei ake i era atu moata whakawera waiariki parakore.

I tua atu, ko te ihirangi o te cellulose ether te awe i te rahi o te pore, e whakaatu ana i te ahua o te piki haere ka heke iho.He iti ake te rahi o te pore ka rite ki nga uara whakaheke whakamaroke nui ake, engari ko nga rahinga pore nui ake pea ka hono ki nga uara whakaheke whakamaroke iti ake.
