Te Mārama ki ngā Whakatauranga Pēhanga Tino Teitei i roto i ngā Waipēhanga o te Mara Hinu

I mua i te ruku ki ngā whakatauranga pēhanga motuhake, he mea nui kia mārama ki te tikanga o te "pēhanga tino teitei" i roto i te horopaki o ngā ratonga mara hinu, me te mārama he aha te whiriwhiri whakatauranga pēhanga he whakatau e pā ana ki ngā hua nui ki te haumaru, ki te whakahaere, me te pūtea.

Ko ngā pūnaha waipēhi ahumahi tuku iho ka mahi i ngā pēhanga tae atu ki te 35 MPa (5,000 psi). Tērā pea ka mahi ngā taputapu ratonga puna pēhanga teitei i roto i te awhe 70–105 MPa (10,000–15,000 psi). Ko te pēhanga tino teitei, e ai ki te whakamāramatanga i roto i te horopaki o te mara hinu, ka tīmata i te 140 MPa (20,000 psi) pea, ā, ka toro atu ki tua atu — ki ngā pūnaha kua whakatauria ki te 250 MPa (36,000 psi) me runga ake. I ēnei taumata pēhanga, he rerekē rawa te pūtaiao rauemi, te kounga hanga wāhanga, me te kaupapa hoahoa pūnaha e hiahiatia ana i ngā mahi waipēhi paerewa.

Nā te meaKo te pūngao e rongoatia ana i roto i te pūnaha waipēhi ka taurite ki te tapawhā o te pēhanga whakahaere, ka rongoa e te pūnaha 250 MPa te pūngao e toru ngā wā o te pūngao mō ia rōrahi o te pūnaha 140 MPa i te tere rere kotahi. Ko tēnei pūngao e rongoatia ana te mea e āhei ai ngā taputapu UHP ki te mahi i ngā mahi poka wai uaua - engari koinei anō hoki te mea e tino morearea ai ngā hapa whakatauranga pēhanga. Ka pakaru kino te paipa, te hononga, te hiri rānei kua whakatauria mō te 140 MPa e pāngia ana e te 200 MPa, ka tū hei mōrearea nui ki ngā kaimahi me ngā taputapu.
