Ko ngā rauemi ātete kore āhua ka taea te rehu ki te mata mahi mā te hau tere tere, ā, ka piri ki te mata mahi, ka kiia ko ngā rauemi werohanga ātete. Ko te tikanga, ka taea te whakamahi i tētahi momo rauemi whakarewa, i tētahi momo rauemi rere-ake rānei, hei rauemi rehu maroke, hei rauemi rehu mākū rānei, me whakarerekē noa i tōna rahi matūriki me te momo me te nui o ngā tāpiringa. Ko te rauemi pupuhi ātete he momo rauemi ātete kore āhua, he momo rauemi ātete hou, he pai te rere i muri i te tāpiri wai me te whakaoho, me te kore e tahuna, e hanga pēhanga rānei. He iti noa ngā hononga o tōna hanganga pereki, he pakari te hanganga, he pai te ātete hau, ā, ka taea te karo i te urunga o te paura. I te wa ano, ki te whakatauritea ki ngā hua ātete tuku iho, ko ngā āhuatanga o te rauemi ātete jet:
(1) He māmā te here, ā, ka taea te ārai i te pakitara kei puta.
(2) He watea te hanganga, he iti te kaha o te mahi, he teitei te whai huatanga o te mahi pereki, ā, ka taea te whakatinana i te mīhini hanga oumu.
(3) He poto te wā tuku, ā, ka taea te whakaiti i te nui o ngā taonga me te utu.
He whānuitia te whakamahinga o ngā rauemi pupuhi ātete-wai, he mea watea mō te whakamahinga whānui o ngā rauemi. I te nuinga o te wā, ko te rauemi kirikiri e hanga ana i tēnei rauemi ka kiia he rauemi ātete-wai, ā, ko te rauemi paura ka kiia he ranunga (paura ātete-wai, paura pai rānei), me ngā mea here me ngā tāpiringa.
1. Tikanga hanga o te rauemi ātete-rehu
E ai ki te āhua o te rauemi i rehuhia ki te tinana arai (mata mahi), ka taea te wehewehe kia rua ngā wāhanga: te tikanga werohanga rauemi matao me te tikanga werohanga rauemi rewa, rauemi haurua-rewa rānei. Kei roto i tēnei tikanga ngā tikanga e whai ake nei.
Tikanga rehu mura: Ka rehuhia te rauemi ki runga i te arai mahi mā te mura hau propane. I te wā e rehuhia ana, i raro i te mahi a te pāmahana teitei, ka rewa te rauemi, ka rewa-haurua rānei, ka rehu tika ki runga i te arai pāmahana teitei, ka piri ki te mata o te arai. I mua, i whakamahia hei whakatika i ngā arai oumu, engari kāore i te whakamahia whānuitia i ēnei rā.
Tikanga rehu parāma: Ka rehuhia te rauemi i roto i te āhua katote, he mea onge te whakamahi i roto i ngā rauemi ātete-wera.
Te tikanga tauhiuhi para: pērā i te tauhiuhi para o te kaitahuri hei tiaki i te oumu, ka pupuhihia te ranunga o te rauemi ātete me te para ki runga i te mata o te kaitahuri mā te whakamahi i te tao hāora pēhanga teitei. Koinei te hangarau matua hei whakapai ake i te roa o te ora o te arai kaitahuri.
Ko te tikanga rehu e whakamahia whānuitia ana ko te tikanga rehu maroke me te tikanga rehu mākū.
Tikanga pupuhi maroke: He tukanga whakahaere o tētahi taputapu pupuhi maroke. Ka tomo te rauemi maroke ki roto i te pūwero kakahu hurihuri mai i te silo. Ka huri te pūwero kakahu kakahu i tētahi koki. Ka haria te putanga o runga me te awa hau o te compressor ki te taha o te pūwero kia tūtaki ai ki te wai. I muri i te whakaranu i te rauemi ki te wai i roto i te pūwero, ka rehuhia ki te arai mahi. He pai ake. Ko te nuinga o ngā rauemi i peia ka piri ki te arai mahi, ā, ka hoki whakamuri tetahi wāhanga ka taka ki te whenua. He mea nui te nui o ngā rauemi i ngaro i te whakahokinga mai ki te hanganga o te ātete wera i peia. I te nuinga o te wā, ka whakamahia te tere whakahokinga mai hei tohu i te mahi mimiti o te rauemi i peia. Ko te iti o te tere whakahokinga mai, ko te pai ake. He maha ngā āhuatanga e pā ana ki te tere whakahokinga mai: ko te nuinga ko te nui o te wai, te pēhanga hau me te rahinga hau.
Ko te tikanga rehu mākū he tikanga e pupuhihia ana te ipu whakarewa me te rere pai ki te pūwero mā roto i te paipa, ā, ka rehuhia ki runga i te arai mahi e te rere hau pēhanga teitei i roto i te pūwero. E whā ngā wāhanga matua o te tukanga: te whakaranu, te papu, te rehu me te whakapakeke. Kāore te tukanga whakaranu me te papu i tino rerekē i ngā ipu whakarewa noa me ngā rauemi papu, me whakaranu ōrite me te mahi papu pai.
I ngā wā o mua, ko te hanganga rehu i whakamahia mō te whakatika i ngā arai oumu, engari ko te rehu mākū ka taea te whakamahi tika mō te arai. Ka taea te whakamahi tika ki te hanga arai koko me te oumu o ngā oumu rerekē. Ko ōna painga he māmā te tukanga, kāore he tauira, he iti te utu, ā, he tere te tere.
2. Ngā mea hei aro atu i roto i te tikanga rehu
(1) Me aro atu ki ēnei mea e whai ake nei ina whakamahia te tikanga rehu maroke:
Me tika te nui o te wai e tāpirihia ana: ki te iti rawa te nui o te wai e tāpirihia ana, e kore te rauemi e mākū pai, ā, ka ngāwari te hoki mai o te rauemi maroke; ki te nui rawa te nui o te wai e tāpirihia ana, ka rere te paninga i hangaia e te rehu, ka whakaitihia hoki te kaha mimiti.
Me tika te pēhanga hau me te rōrahi hau o te rehu: ina nui rawa te matūriki, ka nui rawa te pānga o ngā matūriki ki te mata o te rehu, ā, ka ngāwari te hoki whakamuri; ki te iti rawa, kāore e ranea te piri o te rauemi ki te rauemi, ā, ka ngāwari te taka atu.
Me tika te tawhiti me te koki i waenganui i te pū o te pū rehu me te mata rehu: kaua e nui rawa, e iti rawa rānei te kaha o te rehu i te rauemi ki te mata rehu. Me neke te pū rehu ki runga, ki raro, ki maui, ki matau hoki kia ōrite te matotoru o te paparanga rehu.
Kaua te matotoru o ia rehu e tino matotoru: he ngāwari te tihore i te matotoru rawa, ko te tikanga kaua e neke atu i te 50mm.
Whakahaerehia te kirihou me te whakapūmau o te rauemi: ka taea te piri pai o te rauemi ki te paninga rehu, ā, ka taea te whakapakeke wawe kia whiwhi ai i tētahi kaha.
(2) He maha ngā āhuatanga e pā ana ki te tikanga pupuhi mākū. Ko ngā mea matua koia ēnei:
Te Hanganga o te Rauemi Rehu Tuatahi, me whai rahi matūriki e tika ana, te ōwehenga o te matūriki ki te matrix me te nui o te makuku. Mā te taunga tika, ka pai ake te piri o te wāhanga matrix ki te mata o ngā matūriki. Kaua te paparanga piri e matotoru rawa, e angiangi rawa rānei, kia pai ai te āhua o ngā matūriki, kia piri ai ki te paparanga rauemi ina rehuhia ki runga i te paparanga rauemi. Ko ngā mea e whakamahia whānuitia ana ko te konutai aluminate, te konutai silicate, te polysodium chloride, te konupūmā chloride, te konumohe sulfate, te pāhare pākawa konupūmā sulfate, me ētahi atu.
Mena he iti rawa te pēhanga o te jet me te tere o te hau jet, e kore ngā matūriki e piri pai ki te rauemi, ā, ki te nui rawa, ka ngāwari noa te hoki whakamuri.
He pānga nui tō te tawhiti me te koki i waenganui i te pū rehu me te tinana rehu ki te tere piri o te paparanga rauemi.
