Whakamahana Paipa Hau
Whakataki mō te Whakamahana o te Pūwero Hau
Ko te nuinga o te wā ka whakamahia ēnei mō te whakamahana i te hau i roto i ngā paipa hau, ā, e toru ngā rahi e wātea ana: te pāmahana iti, te pāmahana waenga, me te pāmahana teitei. Ko tō rātou āhuatanga hanganga noa ko te whakamahinga o ngā pereti maitai hei tautoko i ngā ngongo whakamahana hei whakaiti i te wiri, ā, kua tāutahia he taputapu whakahaere pāmahana nui ki roto i te pouaka hononga. Haunga te tiaki pāmahana nui, kua tāutahia he taputapu hononga i waenganui i te pā hau me te whakamahana hei whakarite kia tīmata te whakamahana i muri i te tīmatanga o te pā hau. Kua tāutahia he taputapu pēhanga rerekē i mua me muri i te whakamahana hei ārai i te pakaru o te pā hau. Ko te pēhanga hau e werahia ana e te whakamahana paipa kaua e neke ake i te 0.3 kg/cm². Mena e hiahiatia ana he pēhanga e neke ake ana i tēnei rohe, me whakamahi he whakamahana hiko e rere ana. Ko ngā whakamahana pāmahana iti ka whakamahana i ngā pāmahana hau kāore e neke ake i te 160°C; ko ngā whakamahana pāmahana waenga kāore e neke ake i te 260°C; ā, ko ngā whakamahana pāmahana teitei kāore e neke ake i te 500°C.
Tono
Ko te nuinga o ngā whakamahana hiko he whakamahana i te hau mai i te pāmahana tīmatanga ki te pāmahana e hiahiatia ana. He whānuitia te whakamahinga i roto i ngā taiwhanga rangahau me te whakaputa pūtaiao maha, tae atu ki ngā mea kei roto i ngā rāngai rererangi, patu, matū, me ngā whare wānanga. He tino pai mō te whakahaere pāmahana aunoa me te whakamātautau i ngā pūnaha me ngā taputapu whakauru pāmahana teitei me te rere-teitei. He whānui ngā whakamahinga o ngā whakamahana hau hiko: ka taea e rātou te whakamahana i tetahi hau, ā, ko te hau wera e whakaputaina ana e rātou he maroke, he kore makuku, he kore-kawe, he kore-mura, he kore-pahū, he kore-waikura, he kore-waikura matū. He tino whai hua, ā, ka tere te pikinga o te pāmahana (ka taea te whakahaere) i roto i te wāhi wera.
Ngā Āhuatanga Hangarau
- Ka taea e rātou te whakamahana i te hau ki ngā pāmahana tino tiketike, tae atu ki te 450°C, me te pupuri i te pāmahana anga ki te 50°C anake.
- Whai huatanga: Neke atu i te 0.9.
- He tere te whakamahana me te whakamatao, tae atu ki te 10°C/s, me te whakahaere tere me te pumau. Ka whakakorea e rātou te rerekētanga o te pāmahana i puta mai i te mata pāmahana, i te whakaroa rānei, ā, he mea pai mō te whakahaere aunoa.
- Ngā Āhuatanga Mīhini Tino Pai: he tino pai ngā āhuatanga mīhini me te kaha ki te whakataurite ki tētahi atu huānga whakamahana i raro i te pānga o te rere o te hau pēhanga teitei. Nā tēnei he tino pai mō te whakamātautau i ngā pūnaha me ngā taputapu e hiahia ana kia whakamahana tonutia te hau mō ngā wā roa.
- He pakari, ā, ka roa te ora mō ngā tekau tau ina whakamahia i raro i ngā tikanga kua tohua.
- He hau ma, he rahi kiato hoki.
