pūtē whakarārangi kākano karbona
He pūnaha whakarārangi karbona iho he whakariangahanga hanganga matihiko e whakatupu ana i ngā mātātuhi hirere āhuarangi mō te whakauru i ngā rauropi whakapai taurite ki roto i ngā whakamahi matihiko. Ko tēnei kōwhiringa matihiko ka whakamahi i ngā momo hunga matihiko o nehe hei whakarārangi i ngā niho karbona iho ki runga i tētahi mandrel i ngā rarangi tirohanga kua tohua, whakatupu ai ngā wharepōro tahitahia rānei me ngā wharepōro koni. Ka mahi te pūnaha i runga i tētahi rangitaki rorohiko e whakahaere ana i ngā take niho, ngā tirohanga whakarārangi, me te taipu resina. Ko ōna take nui ko te whakarite i te whakatakoto niho hirere, te whakahaere tika i ngā take here, me te whakaaweawe pūnaha whakaatu mandrel, e whai ana i te paihere katoa o te kaiwhakauru. Ko te hunga whakahaere motuhake e whakauri ana i te hunga whakahaere, e whakamana ana i ngā rarangi whakarārangi pūnaha matihiko me ngā whiuwenua pūnaha. Ko ngā pūnaha whakarārangi karbona iho o nāianei ka whakauri i ngā raraunga paiarahinga kaiwhakahaere, i te whakahaere porihanga i te wā, me ngā take whakarārangi hurihuri. E whai ana enei pūnaha i ngā whakamahi nui atu i waenga i ngā whenua paerewa, araero, kōmu kaitahi, me ngā hanganga noa iho. Ka pai ake rātau ki te whakauru i ngā wāhi pausanga, ngā pīpa, ngā pūru hīkoi, me ētahi atu kōmaha tahitahia e hiahiatia ana ngā uara paihere ki ngā uara mana. Ko te whanaketanga o te pūnaha kei te whakatupu i ngā mātātuhi whakapai taurite nui me ngā mātātuhi whakauru tūhono, he mea nui tēnei ki roto i ngā hanganga whakapai taurite.
