Ko nga hua ether cellulose HPMC me HEMC he roopu hydrophobic me te hydrophilic. Ko te roopu methoxy he hydrophobic, he rereke te roopu hydroxypropoxy i runga i te waahi whakakapi. He hydrophilic etahi, he hydrophobic etahi. Ko te Hydroxyethoxy he hydrophilic. Ko te mea e kiia nei ko te hydrophilicity te tikanga kei a ia te mana o te tata ki te wai; ko te hydrophobicity te tikanga kei a ia te mana ki te tarai i te wai. I te mea he hydrophilic me te hydrophobic te hua, he mahi mata te hua cellulose ether, e hanga ai nga mirumiru hau. Mena ko tetahi o nga taonga e rua he hydrophilic, hydrophobic ranei, karekau he mirumiru e puta. Heoi ano, he roopu hydrophilic anake o te roopu hydroxyethoxy a HEC, kaore he roopu hydrophobic, na reira ka kore e whakaputa mirumiru.
Ko te ahuatanga o te mirumiru e pa ana ki te tere o te whakakorenga o te hua. Mena ka memeha te hua i te reiti koretake, ka puta nga mirumiru. I te nuinga o te waa, ko te iti o te pokey, ka tere ake te tere o te whakakore. Ko te teitei ake o te pokey, ka puhoi te tere o te whakakore. Ko tetahi atu take ko te raruraru granulation, he pāhiwihiwi te granulation (karekau he rite te rahi o te matūriki, he nui me te iti). He rereke te wa rewa, ka puta te mirumiru hau.
Ko nga painga o nga mirumiru hau ka taea te whakanui ake i te waahi o te pakaru o te puranga, ka pai ake te hanga whare, ka mama ake te slurry, ka ngawari ake te tango i te puranga. Ko te kino ko te noho o nga mirumiru ka whakaiti i te nui o te hua, ka whakaheke i te kaha, ka pa ki te aukati huarere o te rauemi.
