He aha te rerekētanga i waenga i te paipa maitai kore hononga kua hurihia wera me te paipa maitai kore hononga kua hurihia matao? He paipa maitai kore hononga kua hurihia wera te paipa maitai kore hononga noa?
He iti te whānui o ngā paipa rino kore-whakakorikori matao, ā, he nui te whānui o ngā paipa rino kore-whakakorikori wera. He teitei ake te tika o ngā paipa rino kore-whakakorikori matao i ērā o te paipa rino kore-whakakorikori wera, ā, he nui ake anō hoki te utu i ērā o te paipa rino kore-whakakorikori wera.
Nā te rerekētanga o ngā tukanga hanga, ka wehea ngā paipa maitai kore hononga ki ngā paipa maitai kore hononga kua hurihia wera (kua whakaputahia) me ngā paipa maitai kore hononga kua kumea matao (kua hurihia). Ka wehea ngā paipa kua kumea matao (kua hurihia) ki ngā paipa porowhita me ngā paipa āhua motuhake.
1) Ko ngā paipa tuitui wera-hurihuri mō ngā kaupapa rerekē ka wehea ki ngā paipa rino noa, ngā paipa rino pēhanga iti me te waenga, ngā paipa rino pēhanga teitei, ngā paipa rino koranu, ngā paipa rino kowiri tira, ngā paipa pakaru hinu, ngā paipa rino whenua me ētahi atu paipa rino. Ko ngā paipa rino tuitui matao-hurihuri (waea) ka wehea ki ngā paipa rino noa, ngā paipa rino pēhanga iti me te waenga, ngā paipa rino pēhanga teitei, ngā paipa rino koranu, ngā paipa rino kowiri tira, ngā paipa pakaru hinu me ētahi atu paipa rino, tae atu ki ngā paipa rino angiangi waro, ngā paipa rino angiangi koranu, me ngā paipa rino angiangi koranu. Paipa rino, paipa rino āhua motuhake.
2) Ko te whānui o waho o ngā paipa kore-whakarewa wera o ngā rahi rerekē he nui ake i te 32mm, ā, ko te matotoru o te pakitara he 2.5-75mm. Ka taea e te whānui o te paipa kore-whakarewa matao te eke ki te 6mm, ā, ka taea e te matotoru o te pakitara te eke ki te 0.25mm. Ka taea e te whānui o waho o te ngongo angiangi te eke ki te 5mm, ā, ko te matotoru o te pakitara he iti iho i te 0.25mm. He nui ake te tika o te āhua o te hurihuri matao i te hurihuri wera.
3) Ngā Rerekētanga o te Tukanga 1. Mā te maitai hanga hurihuri-matao ka taea te piko ā-rohe o te wāhanga, ka taea ai te whakamahi katoa i te kaha kawe o te pae i muri i te piko; ko te maitai hurihuri-wera ia kāore e taea te piko ā-rohe o te wāhanga.
2. He rerekē ngā take mō te ahotea toenga o te maitai hurihuri wera me te maitai hurihuri matao, nō reira he tino rerekē hoki te tohatoha i runga i te wāhanga whakawhiti. He piko te tohatoha ahotea toenga o ngā wāhanga maitai pakitara angiangi hanga-matao, ko te tohatoha ahotea toenga o ngā wāhanga maitai hurihuri wera, whakarewa rānei he rite ki te kiriata.
3. He teitei ake te pakari o te takahuri kore utu o te maitai hurihuri wera i te maitai hurihuri matao, nō reira he pai ake te ātete takahuri o te maitai hurihuri wera i te maitai hurihuri matao.
4) Ngā painga me ngā ngoikoretanga rerekē Ko ngā paipa kore-whakakorikori matao e pā ana ki ngā pepa maitai, ki ngā rīpene maitai rānei e tukatukahia ana hei momo maitai mā te kukume matao, te piko matao, me te kukume matao i te pāmahana rūma.
Ngā Painga: He tere te hanga, he teitei te putanga, ā, kua pakaru te paninga, ā, ka taea te hanga hei momo āhua whakawhiti-wāhanga hei whakatutuki i ngā hiahia o ngā tikanga whakamahinga; ka taea e te hurihuri makariri te whakaputa i te ahua kirihou nui o te maitai, ā, ka piki ake te kaha tuku o te pūwāhi maitai.
Ngā Huakore: 1. Ahakoa kāore he pēhanga kirihou wera i te wā e hangaia ana, kei te toe tonu te ahotea i roto i te wāhanga, ka pā kino ki ngā āhuatanga piko whānui me te piko ā-rohe o te maitai; 2. Ko te maitai wāhanga hurihuri-matao he wāhanga tuwhera i te nuinga o te wā, ka iti te pakari o te takahuri kore utu o te wāhanga. .He ngāwari ki te takahuri i te wā e piko ana, he ngāwari ki te piko me te takahuri i te wā e pēhia ana, ā, he ngoikore te ātete takahuri; 3. He iti te matotoru o te pakitara o te maitai hurihuri-matao, ā, kāore i te matotoru ngā kokonga hono o ngā pereti, nō reira he ngoikore te kaha ki te waha i ngā kawenga kukū ā-rohe.
He rite te āhua o ngā paipa tuitui wera-hurihuri ki ngā paipa tuitui matao-hurihuri. Ka hurihia ngā paipa tuitui matao-hurihuri i raro iho i te pāmahana hangarua, ā, ka hurihia ngā paipa tuitui wera-hurihuri i runga ake i te pāmahana hangarua.
Ngā Painga: Ka taea te whakangaro i te hanganga whakarewa o te ingot, te whakapai ake i te kakano o te maitai, te whakakore i ngā hapa o te hanganga, te whakakīkī i te hanganga maitai, me te whakapai ake i ngā āhuatanga miihini. Ko te nuinga o tēnei whakapainga ka kitea i te ahunga hurihuri, kia kore ai te maitai e noho motuhake ki tētahi taumata; ka taea hoki te whakarewa i ngā mirumiru, ngā kapiti me te wetewete i hangaia i te wā o te tukanga whakarewa i te pāmahana teitei me te pēhanga teitei.
Ngā Huakore: 1. Whai muri i te hurihuri wera, ka pēhia ngā mea kore-whakarewa (ko te nuinga he sulfide me ngā waikura, me ngā silicate) i roto i te maitai kia angiangi, ā, ka puta te wehenga (i waenga i te paparanga). Ka tino heke te kounga o te maitai i te ahunga matotoru o te wehenga, ā, ka puta pea te haehae i waenga i te whakarewa ina whakaitihia te whakarewa. Ko te taumahatanga ā-rohe i puta mai i te whakahekenga o te whakarewa ka eke ki ngā wā maha atu i te taumahatanga ira hua, he nui ake i te taumahatanga i puta mai i te kawenga;
2. Te ahotea toenga i puta mai i te whakamatao koretake. Ko te ahotea toenga ko te ahotea taurite-ā-roto me te kore he kaha o waho. Ko ngā wāhanga hurihuri wera o ngā momo whakawhiti he ahotea toenga pēnei. I te nuinga o te wā, ko te nui ake o te rahi o te wāhanga o te kōtaha maitai, ko te nui ake o te ahotea toenga. Ahakoa he taurite-ā-koe te ahotea toenga, he pānga tonu ki te mahi a te mema maitai i raro i te mahi a te kaha o waho. Hei tauira, ka pā kino ki te whakarerekētanga, te pumau me te ātete ngenge.
3. He uaua te whakahaere i ngā hua maitai hurihuri-wera i runga i te matotoru me te whānui o te taha. E mōhio ana tātou ki te whakawhānui me te whakaheke wera. Nā te mea i te tīmatanga, ahakoa te roa me te matotoru e eke ana ki te paerewa, ka kitea he rerekētanga kino i muri i te whakamatao whakamutunga. Ko te nui ake o te rerekētanga kino, ko te matotoru ake o te matotoru, ā, ko te kitea ake o te mahi.
