He Tirohanga Whānui mō te Koiri Rino Hurihia Matao

He mea hanga te pōkai hurihuri matao i te pōkai hurihuri wera. I roto i te tukanga hurihuri matao, ka hurihia te pōkai hurihuri wera i raro i te pāmahana whakahou, ā, ka hurihia te maitai hurihuri i te pāmahana rūma. He iti te pakarukaru o te pepa maitai he nui te ihirangi silicon, he iti hoki te kirihou, ā, me whakamahana anō ki te 200 °C i mua i te hurihuri matao. Nā te mea kāore te pōkai hurihuri matao e whakamahanahia i te wā o te tukanga whakaputa, kāore he hapa pērā i te poka me te waikura rino e kitea pinepine ana i roto i te hurihuri wera, ā, he pai te kounga o te mata me te whakaotinga.

1. Ko te waitohu Haina Nama Q195, Q215, Q235, Q275——Q—te waehere o te pūwāhi hua (rohenga) o te maitai hanganga waro noa, koinei te tauira o te reta oro Hainamana tuatahi o "Qu"; 195, 215, 235, 255, 275 - e tohu ana i te uara o tō rātou pūwāhi hua (rohenga), ko te waeine: MPa MPa (N / mm2); nā te kaha whānui o te maitai Q235, te kirihou, te pakari me te kaha whakarewa i roto i te maitai hanganga waro noa. Ko te mea nui, ka taea e ia te whakatutuki pai ake i ngā whakaritenga whānui o te whakamahinga, nō reira he whānui rawa te whānuitanga o te tono.
2. Waitohu Hapanihi SPCC - Rino, Pereti-P, C-makariri, tuawhā C-noa.

Te Whakamahinga o te Koiri Rino Hurihia Matao

He pai te mahi a te koiri hurihuri-matao, arā, mā te hurihuri-matao, ka taea te whiwhi i te matotoru angiangi o te rīpene hurihuri-matao me te pepa maitai me te tino tika, he tika teitei, he maeneene teitei te mata, he ma, he kanapa te mata o te pepa hurihuri-matao, me te ngawari ki te paninga. Ko te tukatuka whakakikorua, te momo, te whānui o te whakamahinga, me ngā āhuatanga o te mahi tā me te kore e tawhito, he iti te pūwāhi hua, nō reira he whānui ngā whakamahinga o te pepa hurihuri-matao, ko te nuinga e whakamahia ana i roto i ngā motuka, ngā pahu rino tā, te hanga, ngā rauemi hanga, ngā pahikara, me ētahi atu. Ko te umanga hoki te whiringa pai rawa atu mō te hanga pepa maitai pania waro.
