I roto i te hanga rauemi hanga, inā koa te moata paura maroke,te etera celluloseHe mea nui te mahi a te cellulose ether, inā koa i roto i te hanga o te moata motuhake (moata whakarerekētia), he wāhanga nui. Ko te mahi nui a te cellulose ether wairewa-wai i roto i te moata ko tōna kaha pupuri wai pai rawa atu. Ko te pānga pupuri wai o te cellulose ether e whakawhirinaki ana ki te mimiti wai o te paparanga turanga, te hanganga o te moata, te matotoru o te paparanga moata, te hiahia wai o te moata, me te wā whakatakoto o te rauemi whakatakoto.
He maha ngā moata pereki me ngā moata parai kāore e mau pai te wai, ā, ka wehe te wai me te paru i muri i ētahi meneti o te tūnga. He mahi nui te pupuri wai o te methyl cellulose ether, ā, he mahi anō hoki tēnei e arohia ana e te nuinga o ngā kaihanga moata ranunga maroke o te whare, inā koa ko ērā kei ngā rohe tonga he nui te pāmahana. Ko ngā āhuatanga e pā ana ki te pānga pupuri wai o te moata paura maroke ko te nui o te tāpiri, te matotoru, te pai o ngā matūriki, me te pāmahana o te taiao whakamahi.
Te pupuri wai ote etera celluloseI ahu mai anō i te wairewatanga me te maroketanga o te cellulose ether tonu. E mōhio ana tātou katoa, ahakoa he nui ngā rōpū OH tino wairewa kei roto i te mekameka ngota cellulose, kāore e wairewa i roto i te wai, nā te mea he nui te tioata o te hanganga cellulose. Kāore te kaha wairewa o ngā rōpū hydroxyl anake e ranea ki te hipoki i ngā here hauwai kaha me ngā kaha van der Waals i waenga i ngā ngota. Nō reira, ka pupuhi noa engari kāore e wairewa i roto i te wai. Ina whakaurua he whakakapinga ki roto i te mekameka ngota, ehara i te mea ko te whakakapinga anake ka whakangaro i te mekameka hauwai, engari ka whakangaromia hoki te here hauwai i waenga i ngā mekameka nā te herenga o te whakakapinga i waenga i ngā mekameka tata. Ko te nui ake o te whakakapinga, ko te tawhiti i waenga i ngā ngota. Ko te tawhiti nui ake. Ko te nui ake o te pānga o te whakangaro i ngā here hauwai, ka wairewa te cellulose ether i muri i te whānui o te whatunga cellulose me te urunga o te otinga, ka hanga he otinga matotoru teitei. Ina piki te pāmahana, ka ngoikore te wairewa o te polymer, ā, ka peia te wai i waenga i ngā mekameka. Ina rawaka te pānga maroke, ka tīmata te kohikohi o ngā ngota ngota, ka hanga he hanganga whatunga toru-ahu, ka piko.
I te nuinga o te wā, ko te teitei ake o te matotoru, ko te pai ake o te pānga pupuri wai. Heoi, ko te teitei ake o te matotoru me te teitei ake o te taumaha ngota, ko te whakahekenga o tōna wairewa ka pā kino ki te kaha me te mahi hanga o te moata. Ko te teitei ake o te matotoru, ko te kitea ake o te pānga matotoru ki te moata, engari kāore i te ōrite tika. Ko te teitei ake o te matotoru, ko te matotoru ake o te moata mākū, arā, i te wā hanga, ka kitea he piri ki te waru me te piri nui ki te papa. Engari kāore e whai hua te whakanui ake i te kaha hanganga o te moata mākū tonu. I te wā hanga, kāore i te kitea te mahi ārai-totoka. I te ritenga ke, ko ētahi matotoru reo me te iti engari he methyl kua whakarerekētia.ngā etera cellulosehe tino pai te mahi ki te whakapai ake i te kaha hanganga o te moata mākū.
