Para Whakarewa Hiraka Warowaihā Ārai-waikura
PWhakaahuatanga hua
Ka whakamahia e tā mātou ipu whakarewa he tukanga whakarewa-mate whakauru, he pai ake te ātete ki te pāmahana teitei me te roa ake o te ora i ngā ipu whakarewa noa, me te whakarite hoki i te kawe wera pai. I runga i tēnei kaupapa, he mea hanga tā mātou ipu whakarewa i ngā rauemi mata kua tohua, ā, mā te tukanga ārai-waikura ahurei ka whakapai ake i te pumau me te whakaroa i te waikura, kia kore ai te konganuku e poke i ngā ipu whakarewa silicon carbide.
Ngā Painga
1) Ātete pāmahana teitei (ko te ira rewa he 3850±50C)
2) Ārai-waikura,
3) Te ātete kaha ki te waikura ki te waikawa me te wai kawakore
4) Ātete ki te pakū,
5) He pai te kawe hiko me te wera 6. He pai te whai hua.
7) Te pumau matū tino pai
8) Ngāwari ki te horoi
9) He pai te takai
Ngā Taunakitanga
1) Me penapena te para i te wāhi maroke.
2) Kia āta kawe i te ipu para
3) Whakamahanahia te parai i roto i te mīhini whakamaroke, i te taha rānei o te oumu. Me eke te pāmahana whakamahana ki te 500ºC.
4) Me whakatakoto te oko para ki raro i te waha o te oumu kia papatahi.
Ina whakanohoia te konganuku ki roto i te para, me whakamahi koe i te kaha o te para hei tohutoro māu. Ki te kī rawa te para, ka pakaru i te whakawhanuitanga.
5) Me rite te āhua o ngā rawhi ki te āhua o te oko whakarewa. Āta karohia te pakaru o te oko whakarewa i te taumahatanga kukū.
6) Horoia te ipu para i ia wā, i ia wā, me te ata hoki.
7) Me whakatakoto te oko tahu ki waenganui o te oumu, me waiho he tawhiti i waenganui i te oko tahu me te oumu.
8) Tahurihia te para kotahi i te wiki, ā, ka āwhina tēnei ki te whakaroa i te roa o te wā mahi.
9) Kaua te mura e pā tika ki te oko tahu.
