Q345He momo rino koranu iti te mea e whakamahia whānuitia ana i roto i ngā piriti, ngā waka, ngā kaipuke, ngā whare, ngā oko pēhanga, ngā taputapu motuhake, me ētahi atu, ko te tikanga o "Q" ko te kaha tuku, ā, ko te tikanga o te 345 ko te kaha tuku o tēnei rino ko te 345MPa.
Ko te whakamātautau i te maitai q345 e whai wāhi ana ki ngā āhuatanga e rua: tuatahi, mēnā kei te eke te ihirangi huānga o te maitai ki te paerewa ā-motu; tuarua, mēnā kei te tutuki te kaha tuku, te whakamātautau kume, me ētahi atu o te maitai i ngā paerewa mā roto i ngā umanga ngaio. He rerekē te ihirangi koranu i te q235, he maitai waro noa, ā, he maitai koranu iti te q345.
Te whakarōpūtanga o ngā rauemi Q345
Ka taea te wehewehe i te Q345 ki te Q345A, Q345B, Q345C, Q345D me te Q345E i runga i te taumata. Ko tā rātou e tohu ana ko te rerekētanga o te pāmahana o te pānga. Taumata Q345A, kāore he pānga; taumata Q345B, pānga pāmahana noa 20 nekehanga; taumata Q345C, pānga 0 nekehanga; taumata Q345D, pānga -20 nekehanga; taumata Q345E, pānga -40 nekehanga. I ngā pāmahana pānga rerekē, he rerekē anō hoki ngā uara pānga.
rerekē.
Te whakamahinga o ngā rauemi Q345
He pai ngā āhuatanga miihini whānui o te Q345, he pai te mahi pāmahana iti, he pai te kirihou me te ngāwari ki te whakarewa. E whakamahia ana hei oko pēhanga reo me te iti, hei tāke hinu, hei waka, hei kereini, hei mīhini keri, hei teihana hiko, hei piriti me ētahi atu hanganga, hei wāhanga miihini, hei hanganga whare, me ngā hanganga whānui e mau ana i ngā kawenga hihiri. Ka taea te whakamahi i ngā wāhanga hanganga whakarewa, e whakamahia ana i roto i ngā āhuatanga hurihuri wera, i ngā āhuatanga noa rānei, mō ngā hanganga rerekē i roto i ngā wāhi makariri i raro i te -40°C.
