Ko tētahi o ngā rerekētanga nui i waenga i te moata maroke-ranu me te moata tuku iho ko te whakarerekētanga o te moata maroke-ranu ki te iti o ngā tāpiri matū. Ko te tāpiri i tētahi tāpiri ki te moata paura maroke ka kiia ko te whakarerekētanga tuatahi, ko te tāpiri i ngā tāpiri e rua, neke atu rānei, ka kiia ko te whakarerekētanga tuarua. Ko te kounga o te moata paura maroke ka whakawhirinaki ki te kōwhiringa tika o ngā wāhanga me te taurite me te whakataurite o ngā wāhanga rerekē. Nā te mea he nui ake te utu o ngā tāpiri matū, ā, he nui ake te pānga ki te mahi a te moata paura maroke. Nō reira, i te wā e whiriwhiri ana i ngā tāpiri, me matua whakaaro ki te nui o ngā tāpiri. Anei tētahi whakataki poto ki te tikanga kōwhiringa o te tāpiri matū cellulose ether.
Ka kiia hoki te cellulose ether ko te rheology modifier, he ranunga e whakamahia ana hei whakatikatika i ngā āhuatanga rheological o te moata hou i konatunatua, ā, e whakamahia ana i roto i te nuinga o ngā momo moata. Me whai whakaaro ki ngā āhuatanga e whai ake nei i te wā e whiriwhiri ana i tōna momo me te horopeta:
(1) Te pupuri wai i ngā pāmahana rerekē;
(2) Te pānga whakamātotoru, te matotoru;
(3) Te whanaungatanga i waenga i te ōritetanga me te pāmahana, me te awe ki te ōritetanga i te aroaro o te irahiko;
(4) Te āhua me te nui o te whakapūngao;
(5) Te whakapai ake i te thixotropy o te moata me te kaha ki te whakanoho (he mea tika tēnei mō te moata kua peitahia ki ngā mata poutū);
(6) Te tere o te whakarewatanga, ngā āhuatanga me te otinga o te whakarewatanga.
Haunga te tāpiri i te cellulose ether (pērā i te methyl cellulose ether) ki te moata paura maroke, ka taea hoki te tāpiri i te polyvinyl acid vinyl ester, arā, te whakarerekētanga tuarua. Ka taea e ngā here kore-waro (sima, gypsum) i roto i te moata te whakarite i te kaha pēhi teitei, engari he iti noa te pānga ki te kaha kume me te kaha piko. Ka hangaia e te polyvinyl acetate he kiriata pīwariwari i roto i ngā pūwero o te kōhatu sima, ka taea ai e te moata te tu atu i ngā kawenga whakarerekētanga teitei me te whakapai ake i te ātete kakahu. Kua whakamātauhia e te mahi mā te tāpiri i ngā rahinga rerekē o te methyl cellulose ether me te polyvinyl acid vinyl ester ki te moata paura maroke ka taea te whakarite i te moata here pereti paninga angiangi, te moata parai, te moata peita whakapaipai, me te moata pereki mō ngā poraka raima hau me te moata whakataurite-ake mō ngā papa ringihanga, me ētahi atu. Mā te whakaranu i ngā mea e rua, ehara i te mea ka whakapai ake i te kounga o te moata, engari ka tino whakapai ake hoki i te whai huatanga o te hanga.
I roto i te whakamahinga mahi, kia pai ake ai te mahi whānui, me whakamahi ngā tāpiringa maha hei whakakotahi. He ōwehenga ōrite pai rawa atu kei waenga i ngā tāpiringa. Mena he tika te whānuitanga horopeta me te ōwehenga, ka taea e rātou te whakapai ake i te mahi a te moata mai i ngā āhuatanga rerekē. Heoi, ina whakamahia takitahi, he iti noa te pānga whakarerekētanga ki te moata, ā, i ētahi wā ka puta he pānga kino, pērā i te tāpiri i te cellulose anake, me te whakanui ake i te piri o te moata me te whakaiti i te taumata o te wehenga, ka nui ake te wai e pau ana i te moata, ka noho ki roto i te paru, ka heke te kaha pēhi; Ina konatunatua ki te kaihoko whakauru hau, ahakoa ka taea te whakaiti i te taumata o te paparanga o te moata, ā, ka tino heke hoki te wai e pau ana, ka heke te kaha pēhi o te moata nā te nui ake o ngā mirumiru hau. Hei whakapai ake i te mahi a te moata pereki ki te taumata nui rawa atu, me te karo i te kino ki ētahi atu āhuatanga o te moata, me tutuki te ōritetanga, te paparanga me te kaha o te moata pereki ki ngā whakaritenga o te kaupapa me ngā whakaritenga hangarau e tika ana. I taua wā anō, kāore he whakapiri raima e whakamahia ana, hei penapena i te sima, te tiaki taiao, me ētahi atu, me mahi i ngā mahi whānui, te whakawhanake me te whakamahi i ngā ranunga hiato mai i ngā tirohanga o te whakaiti wai, te whakanui ake i te matotoru, te pupuri me te whakamātotoru i te wai, me te whakakirikiri e uru ana ki te hau.
