I roto i te moata, ka whai wāhi te cellulose ether ki te pupuri wai, ki te whakamātotoru, ki te whakaroa i te kaha whakamakuku sima, me te whakapai ake i te mahi hanga. Mā te kaha pupuri wai pai ka tino oti te whakamakuku sima, ka taea te whakapai ake i te matotoru mākū o te moata mākū, te whakanui ake i te kaha piri o te moata, me te whakatika i te wā. Mā te tāpiri i te cellulose ether ki te moata rehu miihini ka taea te whakapai ake i te mahi rehu, te papu rānei me te kaha hanganga o te moata. He whānuitia te whakamahinga o te cellulose hei tāpiri nui i roto i te moata kua oti te whakaranu. Hei tauira, he pai ngā āhuatanga o te cellulose ether pērā i te whakamātotoru, te pupuri wai, me te whakaroa. Nō reira, he whānuitia te whakamahinga o te cellulose ether kounga rauemi hanga hei whakapai ake i te hanga o te moata kua oti te whakaranu (tae atu ki te moata kua oti te whakaranu mākū me te moata kua oti te whakaranu maroke), te kapia PVC, me ētahi atu, te peita rapa, te putty, me ētahi atu, tae atu ki te mahi a ngā hua rauemi hanga.
Ka taea e te cellulose te whakaroa i te tukanga whakamakuku o te sima. Ka whakawhiwhia e te cellulose ether ngā āhuatanga pai o te moata, ā, ka whakaitihia hoki te wera whakamakuku wawe o te sima, ka whakaroa hoki i te tukanga hihiri whakamakuku o te sima. Kāore tēnei i te pai mō te whakamahinga o te moata i ngā rohe makariri. Ko tēnei pānga whakaroa ka puta mai i te mimiti o ngā ngota cellulose ether ki ngā hua whakamakuku pērā i te CSH me te ca(OH)2. Nā te pikinga ake o te matotoru o te otinga pore, ka whakaitihia e te cellulose ether te nekenekehanga o ngā katote i roto i te otinga, ā, ka whakaroa i te tukanga whakamakuku. Ko te teitei ake o te kukū o te cellulose ether i roto i te rauemi kohuke ira, ka nui ake te pānga o te whakaroa whakamakuku. Ehara i te mea ka whakaroa noa te cellulose ether i te whakatakoto, engari ka whakaroa hoki i te tukanga whakapakeke o te pūnaha moata sima. Ko te pānga whakaroa o te cellulose ether e whakawhirinaki ana ki tōna kukū i roto i te pūnaha kohuke ira, engari ki te hanganga matū hoki. Ko te teitei ake o te tohu methylation o te HEMC, ka pai ake te pānga whakaroa o te cellulose ether. Ko te ōwehenga o te whakakapinga hydrophilic ki te whakakapinga whakanui wai He kaha ake te pānga whakaroa. Heoi, he iti noa te pānga o te matotoru o te cellulose ether ki te nekehanga whakamakuku sima.
I te pikinga ake o te ihirangi o te hydroxypropyl methylcellulose ether, ka tino piki ake te wā whakatakoto o te moata. He hononga kore-raina pai i waenga i te wā whakatakoto tuatahi o te moata me te ihirangi o te cellulose ether, ā, he hononga raina pai i waenga i te wā whakatakoto whakamutunga me te ihirangi o te cellulose ether. Ka taea e tātou te whakahaere i te wā mahi o te moata mā te whakarerekē i te nui o te cellulose ether.
