He aha te painga o te mirimiri matotoru ki runga i te mahi hangai?

Waku i rotote patupatuKo te waku i waenganui i nga konganuku e rua he rereke te hanganga me nga ahuatanga (ngoi), i waenga i te konganuku ngohengohe (mea mahi) me te whakarewa pakeke (mate). I roto i te take o te kore whakahinuhinu, ko te waku whakapā o rua momo o whakarewa mata waikura kiriata; I raro i te tikanga whakahinuhinu, te waku whakapā i waenganui i te kiriata waikura i runga i nga mata whakarewa e rua, me te reo whakahinuhinu ia, me te waku i waenganui i te mata o te paparanga o roto o te mea mahi, e kore ano i oxidized me he kaha adsorption nui, kei te piki haere te waku i waenga i te momo whakahinuhinu me te mata o te mate me te waahi waku (whakapapa).

Nā ngā āhuatanga waku i waenga i te pātea me te mata whakapā mate i roto i tete tukanga whakaipoipo, ka puta nga hua e whai ake nei:
(1) Ka piki ake te kaha whakarerekētanga ma te 10% na te waku, ka piki ake te kohi hiko;
(2) arata'i waku ki deformation pāhiwihiwi o forgings, kia kore e rite te hanganga witi o roto me te mahi, a ka heke te kounga mata;
(3) ko te waku ka heke iho te ahua ahuahanga me te tika o te ahu o te whariki, e arai atu ai ki te mokemoke o nga whao i te wa e kore e whakakiia nga whao;
(4) Ko te waku ka kaha te mau o te mate, ka whakapoto i tona ora;
(5) Ko te whakanui ake i te parenga waku o te rohe ka taea te hanga i te kohao he uaua ki te whakaki i te whakarewa maeneene me te whakaheke i te reiti whakangao.
Ka kitea ko te waku he hoari matarua i roto i tehanga hanga, kei a ia nga painga me nga ngoikoretanga. Na reira, me tino whakahaere te waku i roto i te mahi hangai ki te whakarite i te mahi hangai noa.
