Hangarau whakarewa maeneene mō ngā ngongo tapawhā
Tekore honongahangarau whakarewa mōngā ngongo tapawhāKua whakaatu i te mahi tino pai i roto i te whakarewa ngongo tapawhā, kua whakapai ake i te tika me te whakaoti o ngā hononga paipa, ā, kua hinga i ngā ngoikoretanga o ngā hononga e pā ana ki te āhua i te wā whakarewa. Ka taea e ia te whakakore pai i ngā whakarewa, ngā whakawhiti me ngā rārangi wehewehe o ngā hononga paipa. Ko te mea nui o tēnei tukanga ko te whakamahinga o te hangarau matatau me ngā pokapū miihini poutū, ka taea te whakaputa pokepoke i roto i tētahi huarahi hou rawa atu. I taua wā anō, ka whakamahia te hangarau huringa whakamahana me te whakamatao whai hua i te wā hanga. Ko ngā āhuatanga o te hangarau whakarewa kore hononga o ngā kaihanga ngongo tapawhā koia ēnei:
(I) I ngā mahi whakaputa o mua, i whakaritea te paipa whakamatao ki te taha o te mata o te ngongo tapawhā, ā, kāore i te ōrite te āhua o te mata. I ētahi tukanga hou, mā te whakatakoto i te rere o te wai o ngā paipa whakamatao matua me te kōhao ki te taha o te wāhi werohanga, ka taea te whakapūmau i te kounga o te ngongo tapawhā i hangaia;
(II) Mā te putanga mai o te hangarau whakarewa korekore ka taea te whakarerekē i te hoahoa o te awaawa me te whakamahi i te mira pokapū miihini poutū polyhedron. I roto i te tukanga whakakoi tuturu, ka taea e ngā panonitanga o te hoahoa awaawa te āwhina ki te whakahaere i ngā huringa pāmahana tino pai mō te whakamahana me te whakamatao i ngā ngongo tapawhā;
(iii) E kore te whakamahinga o te hangarau whakarewa kore hononga e whakapiko me te whakarerekē i ngā ngongo tapawhā, e kore hoki e raru te taurite o te kōhao pokepokea ai me te pokepokea ai i te taha o te uho. Nā te mea ka taea te whakatītaha i te mea mahi, ka karohia te whakamahinga o ngā taputapu mira pōro anake mō te tukatuka i te mata o te pito, ka roa ake te ora o te taputapu mira;
(iv)Ngā kaihanga ngongo tapawhāte whakamahi i te hangarau whakarewa kore hononga, e kore e taea anake te āwhina ki te whakakore i ngā whakarewa pokepokea ai, engari ka whakapai ake hoki i te tika, te whakaoti me te āhua o ngā ngongo tapawhā;
(v) Mā te hangarau whakarewa korekore o ngā kaihanga ngongo tapawhā ka taea te pupuri i ngā rerekētanga pāmahana i roto i te 60°C mā te huri i ngā rūma urunga waenga-diameter nui. Ka hurihia ēnei rūma urunga ki muri i te kōhao pokepokea ai, ā, he rite tonu tō rātou āhua ki te kōhao pokepokea ai. Ka taea e rātou te mahi hei awa mō te mamaoa pēhanga teitei me te wai whakamatao, ā, ka taea te whai wāhi ki te kawe wera ki runga i te mata o te kōhao pokepokea ai, kia ōrite ake ai te tohatoha pāmahana, kia mau tonu ai ngā huringa pāmahana me te whakahaere i te tere o te piki me te heke o te pāmahana;
