Kua roa te wā e whakamātauhia ana, e whakatairangahia ana hoki te hanga miihini i Haina, engari kāore anō kia kitea he ahunga whakamua nui. Haunga te whakahē a te iwi mō ngā huringa whakararuraru ka kawea mai e te hanga miihini ki ngā tikanga hanga tuku iho, ko te take matua ko te mea i raro i te tikanga tuku iho, ko te moata i konatunatua ki te papaanga ka ārai pea i ngā paipa me ētahi atu kaupapa i te wā o te tukanga hanga miihini nā ngā raruraru pēnei i te rahi me te mahi o te matūriki. Ehara i te mea ko te ahunga whakamua o te hanga anake ka pāngia e ngā hapa, engari ka whakanui ake hoki i te kaha o te hanga, ka whakatupu i te wehi o ngā kaimahi ki ngā uauatanga me te whakanui ake i te uauatanga mō te whakatairanga i te hanga miihini.
I ngā tau tata nei, nā te whakatūnga o ngā wheketere moata maroke-whakaranu nui puta noa i te motu, kua whakamanahia te kounga me te pumau o te moata. Heoi, ka tukatukahia, ka hangaia hoki te moata maroke-whakaranu e ngā wheketere. Mō ngā rauemi mata anake, me teitei ake te utu i te ranu i te papaanga. Ki te haere tonu te paninga ā-ringa, kāore he painga whakataetae ki te moata whakaranu i te papaanga, ahakoa he whenua kei reira. Nā te kaupapa here "aukati moni", kei te raru tonu ngā wheketere moata maroke-whakaranu hou ki te whakatutuki i ngā hiahia, ā, i te mutunga ka pakaru.
He kupu whakataki poto ki te mahi whānui o te moata rehu mīhini
Ki te whakatauritea ki te moata tuku iho i konatunatua ki te papaanga, ko te rerekētanga nui o te moata rehu mīhini ko te whakaurunga o te raupapa o ngā ranunga pēnei i te hydroxypropyl methyl cellulose ether hei whakapai ake i te mahi a te moata, kia pai ai te mahi a te moata hou kua konatunatua. , he tere pupuri wai teitei, ā, he pai tonu te mahi i muri i te papu tawhiti me te teitei. Ko tōna painga nui ko tōna whai huatanga hanga teitei me te kounga pai o te moata i muri i te whakakoi. Nā te mea he tere tīmatanga nui te moata i te wā rehu, ka taea e ia te pupuri kaha ki te papa, ka taea ai te whakaiti i te āhuatanga o te poka me te ngatata.
I muri i ngā whakamātautau tonu, i kitea i te wā e whakarite ana i te moata parai i rehuhia e te mīhini, ka whakamahia te onepu i hangaia e te mīhini me te rahi matūriki mōrahi o te 2.5mm, te ihirangi paura kōhatu iti iho i te 12%, me te taumata tika, te rahi matūriki mōrahi rānei o te 4.75mm me te ihirangi paru iti iho i te 5%. Ina whakahaeretia te tere pupuri wai o te moata hou i konatunatua ki runga ake i te 95%, ka whakahaeretia te uara ōritetanga ki te 90mm, ā, ka whakahaeretia te ngaronga ōritetanga 2h i roto i te 10mm, he pai te mahi papu me te mahi rehu o te moata. Ā, he maeneene, he ma te āhua o te moata i hangaia, he ōrite, he momona te paru, kāore e totohu, kāore e poka, kāore hoki e ngatata.
Kōrero mō ngā Tāpiringa Whakakotahi mō te Moata Rehu Mīhini
Ko te tukanga hanga o te moata rehu mīhini ko te whakaranu, te papu me te rehu. I runga i te whakaaro he tika te tauira, ā, he tika te kounga o ngā rauemi mata, ko te mahi matua o te tāpiri matū moata rehu mīhini ko te whakapai ake i te kounga o te moata hou kua whakaranua, me te whakapai ake i te mahi papu o te moata. Nō reira, ko te tāpiri matū moata rehu mīhini whānui he mea hanga mai i te kaihoko pupuri wai me te kaihoko papu. He kaihoko pupuri wai pai te Hydroxypropyl methylcellulose ether, e kore e taea anake te whakanui ake i te matotoru o te moata, engari ka whakapai ake hoki i te rere o te moata me te whakaiti i te wehenga me te toto i raro i te uara ōrite. Ko te kaihoko papu he mea hanga mai i te kaihoko whakauru hau me te kaihoko whakaiti wai. I te wā e whakaoho ana i te moata hou kua whakaranua, ka whakauruhia he maha o ngā mirumiru hau iti hei hanga i te pānga pōro, ka taea te whakaiti i te ātete waku i waenga i ngā matūriki me te whakapai ake i te mahi papu o te moata. I te wā e rehuhia ana te moata i rehuhia e te mīhini, ka ngāwari te wiri iti i puta mai i te hurihanga o te papu kawe tīwiri ka meinga te moata i roto i te hopper kia wehewehea, ka hua ake he uara ōrite iti i te paparanga o runga, he uara ōrite nui i te paparanga o raro, ka ngāwari te aukati i ngā paipa i te wā e rere ana te mīhini, ā, i muri i te whakahāngai, kāore te kounga o te moata i te ōrite, ā, ka ngāwari ki te maroke, ka mimiti, ka pakaru. Nō reira, i te wā e hoahoa ana i ngā tāpiringa hiato mō te moata pupuhi mīhini, me tāpiri tika ētahi whakaū hei whakaroa i te wehewehenga o te moata.
I te wā e whakahaerehia ana e ngā kaimahi te whakamātautau moata i rehuhia ki te mīhini, ko te horopeta o te tāpiringa hiato he 0.08%. He pai te mahi a te moata whakamutunga, he pai te mahi papu, kāore he āhuatanga totohu i te wā o te tukanga rehu, ā, ko te matotoru mōrahi o te rehu kotahi ka eke ki te 25px.
