Ka taea e te cellulose ether te whakapai ake i te mahi a te moata mākū, ā, he tāpiri matua e pā ana ki te mahi hanga o te moata. Mā te whiriwhiri tika i ngā cellulose ether o ngā momo rerekē, ngā matotoru rerekē, ngā rahi matūriki rerekē, ngā nekehanga matotoru rerekē me ngā rahinga tāpiri ka pā pai ki te whakapai ake i te mahi a te moata paura maroke.
He hononga pai hoki kei waenganui i te matotoru o te whakapiri sima me te horopeta o te cellulose ether. Ka taea e te cellulose ether te whakanui ake i te matotoru o te moata. Mēnā he nui ake te horopeta, ka kitea te pānga. He nui te thixotropy o te wai cellulose ether matotoru-teitei, he āhuatanga nui anō hoki tēnei o te cellulose ether.
Ko te pānga matotoru ka whakawhirinaki ki te nui o te whakapūhui o te cellulose ether, te kukū o te otinga, te tere kutikuti, te pāmahana me ētahi atu āhuatanga. He ahurei te āhuatanga whakapūhui o te otinga ki te alkyl cellulose me ōna hua kua whakarerekētia. E pā ana ngā āhuatanga whakapūhui ki te nui o te whakakapinga, te kukū o te otinga me ngā tāpiringa. Mō ngā hua kua whakarerekētia te hydroxyalkyl, e pā ana hoki ngā āhuatanga o te gel ki te nui o te whakarerekētanga o te hydroxyalkyl. Ka taea te whakarite i te otinga 10%-15% mō te MC matotoru iti me te HPMC, ka taea te whakarite i te otinga 5%-10% mō te MC matotoru reo me te HPMC, ā, ka taea anake te whakarite i te otinga 2%-3% mō te MC matotoru teitei me te HPMC. I te nuinga o te wā, ka whakarōpūhia hoki te whakarōpūtanga matotoru o te cellulose ether mā te otinga 1%-2%.
He nui te whai huatanga o te cellulose ether taumaha-ngota teitei ki te whakamātotoru. He rerekē ngā matotorutanga o ngā polymer he rerekē ngā taumaha-ngota i roto i te otinga kukū kotahi. He nui te nekehanga. Ka taea anake te whakatutuki i te matotorutanga whainga mā te tāpiri i te nui o te cellulose ether taumaha-ngota iti. He iti noa te whakawhirinakitanga o tōna matotorutanga ki te tere kutikuti, ā, ka eke te matotorutanga teitei ki te matotorutanga whainga, ā, he iti te nui o te tāpiri e hiahiatia ana, ā, ka whakawhirinaki te matotorutanga ki te whai huatanga whakamātotoru. Nō reira, kia tutuki ai he ōritetanga, me whakapūmau he nui o te cellulose ether (te kukū o te otinga) me te matotorutanga o te otinga. Ka heke haere hoki te pāmahana tiēre o te otinga i te pikinga o te kukū o te otinga, ā, ka tiēre i te pāmahana rūma i muri i te taenga ki tētahi kukū. He teitei te kukū tiēre o te HPMC i te pāmahana rūma.
