He pānga whakaroa tō te cellulose ether ki te moata. Mā te whakanui ake i te horopeta o te cellulose ether, ka roa ake te wā whakatō o te moata. Ko te pānga whakaroa o te cellulose ether ki te whakapiri sima e whakawhirinaki ana ki te nui o te whakakapinga o te rōpū alkyl, engari he iti noa iho te pānga ki tōna taumaha ngota.
Ko te iti o te nekehanga o te whakakapinga alkyl, ko te nui ake o te ihirangi hydroxyl, ā, ko te kitea nuitia o te pānga whakaroa. Ā, ko te teitei ake o te horopeta o te cellulose ether, ko te kitea nuitia o te pānga whakaroa o te paparanga kiriata matatini ki te whakamakuku wawe o te sima, nō reira ka kitea nuitia hoki te pānga whakaroa.
Ko te kaha tētahi o ngā tohu aromatawai nui mō te pānga whakaora o ngā rauemi sima-hangai-sima ki te ranunga. Ina piki ake te horopeta o te cellulose ether, ka heke te kaha pēhi me te kaha piko o te moata. Ka pai ake te kaha here kume o te moata sima i konatunatua ki te cellulose ether; ka heke te kaha piko me te kaha pēhi o te moata sima, ā, ki te nui ake te horopeta, ka iti ake te kaha;
I muri i te whakaranu i te hydroxypropyl methyl cellulose ether, me te pikinga ake o te horopeta, ka piki ake te kaha piko o te moata sima, kātahi ka heke iho, ā, ka heke haere te kaha kōpeketanga. Me whakahaere te horopeta tino pai ki te 0.1%.
He nui te awe o te cellulose ether ki te mahi here o te moata. Ka hangaia e te cellulose ether he kiriata polymer me te pānga hiri i waenga i ngā matūriki whakamakuku sima i roto i te pūnaha wāhanga wai, e whakatairanga ana i te nui ake o te wai i roto i te kiriata polymer i waho o ngā matūriki sima, e whai hua ana ki te whakamakuku katoa o te sima, ā, ka whakapai ake i te kaha here o te whakapiri i muri i te whakapakeketanga.
I taua wā anō, mā te nui o te cellulose ether e tika ana ka whakarei ake i te kirihou me te ngāwari o te moata, ka whakaiti i te pakari o te rohe whakawhiti i waenga i te moata me te atanga o te papa, ā, ka whakaiti i te kaha paheke i waenga i ngā atanga. Ki tētahi taumata, ka whakarei ake te pānga here i waenga i te moata me te papa.
Hei tāpiritanga, nā te noho mai o te cellulose ether i roto i te whakapiri sima, ka hangaia he rohe whakawhiti atanga motuhake me te paparanga atanga i waenganui i ngā matūriki moata me te hua whakamakuku. Mā tēnei paparanga atanga ka ngāwari ake te rohe whakawhiti atanga, ka iti ake te pakari. Nō reira, ka kaha te hononga o te moata.
