Ngā Mātā Wira Hōhonu: Ko ngā Taputapu Whakapau Mō te Whakapai Momo Mātāpihi Hurihuri

Te mārama ki ngā Mīhini Tārua me tā rātou tūwāhanga ki te whakaputa i ngā taputapu

He aha te Mīhini Tārua?

Ko ngā mīhini tārua kawe i ngā pōro kōwhiti, ka tōia hoki i te whare paku kia paku ake te tatau o ngā wīra ki te whakarite i ngā wīra e hiahiatia ana. Ko te tikanga mahi makariri ka iti ake te tatau o te pōro engari ka pai ake te wīra i ētahi ara. Ka māmā te kiriata, ka piki te kaha, ā, ka māmā ake te āhua o te taraiwa i te wā e paku ana i te taraiwa. Mō ngā kaihanga e hiahiatia ai ngā taraiwa tūturu, he nui ngā whakapai. Kua whakaurua ki ngā taputapu hōu ngā pūnaha whakapakaru ake me ngā rereke kaha e āwhina ai i te kounga kia tūturu mai i te kotahi ki te kotahi kaua ko te tāone whakatika.

Ngā whakamahinga matua ki te whakaputa taputapu

Nga tira kia tahi, he nui ake i te whitu o ngā pere, ngā pere tā, me ngā rivets ka tīmata mai i te wira kua tāwhaihia. E whai ana tēnei tukanga i te āhua whakapā whiti i te tata ki te tāpiri, tango 0.01 mm, he mea nui tēnei kia pai ai te mahi tōtika o ngā kiri. He mea hoki ki te mātua koiora ko te mea ka taea e ngā kaihanga te whiwhi i ngā taumata whakarewa tae noa ki te 450 HV mō ngā wira paraihe karaihe, ā, kia noho tonu te whakarewa kia kaua e pakaru i ngā whakatinanatanga pāpaku. Ko te kitea tēnei wāhi hōu e whai kiko ai te whakarewa, ko te tukanga wira tāwhaihanga tētahi o ngā tahua matua ki te hanga i ngā tāpapa e herea ai te wharaunui, e kitea ana i ngā waka, waka hau, me ētahi atu. Kāore tēnei tikanga, kāore ētahi o ngā pūnaha hinana o ā mātou ka taea te kaha ki te tū tonu i te pēhanga.

Te Huri i te Paraihe Kōpū hei Wira Mō ngā Tāpapa

Ko te tīmatanga o te rāwekenga ina whakamahia e ngā kaihanga te mātātoko inu mā te hinga i ngā kaha whakapāpaku. I muri i tēnei wa, ko te kaihau heke i te wai ācid kei te tango i te katoa o ngā ohipa mata. Ko te aha ka tū ake ka tāwhai ko te mea hoki. Trō te nuinga o ngā tauira tāwhai, ka taea e rātou te whakaiti i te tōraro o te pōroki kia tae atu ki te 90%. Engari, kei te eke atu kē! Me whakamahi rātou i ētahi atu whakamātātoko waenganui i te ara hei whakapōuri i ngā mea kia kaua e māmā noa. E ai ki ngā rangahau i tāpiritia i te tau ki muri e te International Wire Association, ko ngā wira e tū ana i ngā tikanga tāwhai tika ka whakaatu i te kaha tāwhai e 30% pai ake tēnei i ā rātou anō kai tōpū. Me te mutunga, i muri i ēnei katoa, ka tū ake te rāwekenga whakamaima. Ko tēnei e waihangatia ai te rārangi ohipa tāwhai ki runga i te paraihe, e whakapono ana kia tāutahia ngā wherenga ASTM F2329 mō te pēhea e manawa tū ai ngā kiriata ki ngā tātai whakapiripiri i ngā whakamahinga o te ao tūmatanui.
