Ngā etera māngaroHe matū wairewa-wai ngā matū nei, he mea hanga mai i te māngaro tūturu mā te whakarerekētanga matū, ā-tinana rānei. E whakamahia ana ēnei i roto i te hanga hei tāpiri hei pupuri i te wai, hei whakamātotoru, hei whakapai ake i te mahi, me te whakarei ake i ngā āhuatanga rheological o ngā rauemi. I te nuinga o te wā ka ahu mai ēnei i ngā māngaro tipu pērā i te kānga, te rīwai, me te manioka. Ka whakaurua ngā rōpū etera mā te tauhohenga etera, ka whakarerekē i tō rātou wairewa, te pumau, me ngā āhuatanga whakamātotoru, ka taea ai e rātou te mahi i roto i ngā taiao kawakore me ngā pūnaha uaua.
I roto i te umanga hanga, he mea whakamahi noa ngā etera māngaro i roto i ngā pūnaha moata whakaranu maroke pērā i ngā piripiri taera, ngā paura putty pakitara o roto, o waho hoki, ngā moata whakamahana, me ngā rauemi whakataurite-ake i ahu mai i te gypsum, i te sima rānei. He iti noa iho te whakamahinga, i waenga i te 0.02% me te 0.1%, engari ka taea e rātou te whakapai ake i te mahi. Ko ngā tikanga matua o te mahi ko:
Te whakatikatika i te ōritetanga me te rheology: Ka pupuhi ngā ether māngaro i roto i te wai hei hanga i tētahi otinga matotoru. Ina whakamahia ngātahitia me ētahi atu matū whakamātotoru (pērā i te hydroxypropyl methylcellulose (HPMC) me te hydroxyethyl methylcellulose (MHEC), ka taea e rātou te whakapai ake i te uara hua me te thixotropy o te moata, kia pai ai te rere i te wā e whakamahia ana, kia iti ake ai te totohu i muri i te tūnga.
Te whakapai ake i te pupuri wai: He tino pai ki te wai ngā ngota māngaro kua whakarerekētia, ka mimiti me te raka ki te wai, ka whakaiti i te mimiti wai me te mimiti mai i te papa, ka whakarite kia rawaka te makuku o te sima, te gypsum rānei, ā, ka whakapai ake i te kaha me te piri.
Te ārai i te totohu me te heke: I roto i ngā piri taera, i ngā tono poutū rānei, ka taea e ngā etera māngaro te whakapai ake i ngā āhuatanga ārai-totohu o te moata. I roto i ngā rauemi whakataurite-ake, i ngā rauemi angiangi-matotoru rānei, ka taea e rātou te whakaiti i te totohu me te whakarite kia maeneene te mata.
Te whakapai ake i te āhua o te tono: Ka māeneene ake te waru me te hora, ka whakaiti i te "piri o te maripi", ka whakapai ake i te whai huatanga o te tono me te kounga o te hua whakamutunga.
He maha ngā wā ka whakamahia ngā etera māngaro me ngā etera cellulose (HPMC, HEMC, me te MHEC) i roto i ngā whakatakotoranga. Ka whakaratohia e ngā etera cellulose ngā āhuatanga matua e pupuri ana i te wai me te whakamātotoru, ko ngā etera māngaro ia ka whakatika i te thixotropy me te ōritetanga o te moata, ka tutuki ai he taurite ake o te mahi. Hei tauira, i roto i ngā whakatakotoranga piri taera, ka taea e te nui o te etera māngaro te whakaiti i te kaha rawa o te uaua i puta mai i ngā etera cellulose matotoru teitei, ka māmā ake te paninga o te moata. I roto i ngā paura putty, ka taea e ia te whakapai ake i te maeneene me te whakaiti i te mōrearea o te mimiti me te ngatata.
I roto i ngā mahi hanga, ka tukuna e ngā etera māngaro ēnei painga mahi e whai ake nei:
He pai mō te taiao: He mea hanga mai i te māngaro tipu tūturu, ka pirau, ā, he iti noa iho te pānga ki te taiao.
Te whai huatanga o te utu: Ka puta he whakapainga nui nā te iti o te whakamahinga, ka whakaiti i te whakawhirinaki ki ngā tāpiringa utu nui.
Te urutau ki te whakatakotoranga: He pai mō ngā moata sima, gypsum, me ngā moata whakauru, ā, he hototahi ki ngā momo tāpiritanga.
Rerekēmāngaro eteraKo ngā momo me ngā tikanga whakarerekētanga ka hua ake he rerekētanga o ngā tere whakarewa, te kaha whakamātotoru, te ātete ki te kawakore, me te pumau. Nō reira, i roto i ngā mahi whaihua, he mea nui kia whiriwhiria te momo tika i runga i te pūnaha whakatakotoranga, te taiao hanga, me te mahi e whakaarohia ana, me te whakatau i te horopeta tino pai mā te whakamātautau. Ko te māngaro ether he tāpiri "horopeta iti, pānga nui" i roto i ngā rauemi hanga. Ka whakapai ake i te rheology moata, te pupuri wai, me te kaha mahi, ka whakanui ake i te pai o te hanga me te kounga o te hua kua oti. He tāpiri mahi tino nui i roto i ngā pūnaha moata maroke-ranu hou.
