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.
