He whānuitia te whakamahinga o te pereki ahi whakamahana māmā i roto i te pūnaha whakamahana o ngā oumu. Nā te whakamahinga o te pereki ahi whakamahana māmā kua tutuki ētahi pānga penapena pūngao me te tiaki taiao i roto i te umanga pāmahana teitei.
He rauemi whakamarumaru te pereki ahi whakamahana māmā, he iti te matotoru, he nui te porowhita, he iti hoki te kawe wera. Nā ōna āhuatanga o te matotoru me te iti o te kawe wera, kāore e taea te whakakapi i roto i ngā oumu ahumahi.
Te tukanga whakaputa opereki ahi whakamahana māmā
1. Paunatia ngā rauemi mata kia rite ki te ōwehenga e hiahiatia ana, hurihia ia rauemi kia paura. Tāpirihia he wai ki te onepu silica hei hanga i te paru, ka whakamahana i te pāmahana o te 45-50 ℃;
2. Tāpirihia ngā rauemi mata e toe ana ki te paraoa pokepoke, ka whakaoho. Kia oti te whakaranu, ringihia te paraoa pokepoke ki roto i te pokepoke ka whakamahana ki te 65-70 °C kia puta he huka. Ko te nui o te huka he nui ake i te 40% o te nui katoa. Kia puta he huka, waiho ki te 40 °C mō ngā haora e 2.
3. Kia tū mārire, tomo ki te rūma korohū mō te korohū, me te pēhanga korohū o te 1.2MPa, te pāmahana korohū o te 190 ℃, ā, ko te wā korohū he 9 hāora;
4. Te whakawera wera nui, te pāmahana 800 ℃.
