Kete tauhohenga whakamahana ngongo haurua-koiri

Ki te whakataurite ki te tauhohenga koti e whakamahia whānuitia ana i Haina, he maha ngā painga o te tauhohenga maitai kore waikura haurua ngongo o waho.

1. Whakaitihia te matotoru o te pakitara o te ipu wai, ā, whakapai ake i tōna kaha ki te pikau i ngā kawenga.

2. He pai mō te whakapai ake i te pai o te whakawhiti wera. Ka taea e ia te whakapai ake i te pūnaha whakamahana me te whakaiti i te ātete wera.

3. Penapenahia te whakapaunga pūngao. Ka whakamahia te ōwehenga o te rōrahi o te koti ki te rōrahi haurua o te paipa hei whakaiti i te haumitanga. He pai te whakaiti i te whānui o te tinana tauhohenga mō te tahora o te awheawhe.

4. Tiakina te maitai.

He tino teitei te pāmahana whakahaere o te ipu tauhohenga, ā, ko te tikanga ka taea anake te whakahaere i ngā tauhohenga matū i raro i ētahi āhuatanga pāmahana, nō reira ka mau te ipu tauhohenga i te pēhanga me te pāmahana. He maha ngā tikanga hei whiwhi i ngā pāmahana teitei:

1. Ka taea te whakamahi ina hiahiatia he pāmahana iti mō te whakamahana wai. E rua ngā momo pūnaha whakamahana: tuwhera me te kati. He tino māmā te momo tuwhera, kei roto ko te papu hurihuri, te tāke wai, te paipa, me te kaiwhakahaere e whakahaere ana i te takirere. Ina whakamahia te wai pēhanga teitei, me kaha te miihini mō ngā taputapu. Ka whakapirihia te mata o waho o te tauhohenga ki te ngongo nakahi, he āputa kei waenganui i te ngongo nakahi me te pakitara tauhohenga, ka whakanui ake i te ātete wera me te whakaiti i te pai o te whakawhiti wera.

2. Ina kei raro iho i te 100 ℃ te pāmahana whakamahana o te mamaoa, ka taea te whakamahi i te mamaoa i raro iho i te pēhanga o te hau; i roto i te awhe 100-180 ℃, whakamahia te mamaoa kua mākū; ina teitei te pāmahana, ka taea te whakamahi i te mamaoa wera nui-pēhanga.

3. I te wā e whakamahanahia ana ki ētahi atu rauemi, mēnā me mahi te tukanga i ngā pāmahana teitei, me te karo rānei i te whakamahi i ngā pūnaha whakamahana pēhanga teitei, ka taea te whakamahi i ētahi atu rauemi hei whakakapi mō te wai me te mamaoa, pērā i te hinu kohuke (275-300 ℃), te ranunga biphenyl ether (te ira kohua 258 ℃), te tote rewa (140-540 ℃), te mata wai (te ira rewa 327 ℃), me ētahi atu.

4. Ka takai te whakamahana hiko i te waea ātete ki te paparanga whakamarumaru o te ipu tauhohenga, ka tāuta rānei ki runga i tētahi ārai motuhake i tētahi tawhiti mai i te ipu tauhohenga, ā, ka hangaia he āputa iti i waenganui i te waea ātete me te ipu tauhohenga. Ko ngā tikanga tuatahi e toru mō te whiwhi pāmahana teitei me tāpiri he koti ki te tinana o te ipu. Nā te nui o te kaha o ngā huringa pāmahana, ka pāngia te koti me te anga o te ipu e ngā huringa pāmahana, ka hua ake he rerekētanga pēhanga pāmahana. Ina whakamahia te whakamahana hiko, he māmā, he māmā hoki ngā taputapu, he ngāwari te whakarite i te pāmahana, ā, kāore he hiahia mō ngā papu, oumu, auahi, me ētahi atu whakaurunga. He ngāwari hoki te tīmata, he iti te mōrearea me te utu. Heoi, he teitei ake te utu whakahaere i ētahi atu tikanga whakamahana, ā, kei raro iho i te 85% te pai o te wera. Nō reira, he pai mō te whakamahana i ngā pāmahana i raro iho i te 400 ℃ me ngā wāhi he iti ake te utu hiko.
