I roto i ngā āhuatanga whakaputa ahumahi, ko te kawe paipa he hononga matua hei whakarite i te maeneene o ngā tukanga, engari ko ngā raruraru pēnei i te pakaru, te waikura, me te pāmahana teitei ka waiho i ngā paipa kia "kino", e kore e piki ake ngā utu tiaki anake engari ka pā kino hoki ki te pai o te whakaputa. I ēnei rā, he rauemi e kiia nei ko "arai uku silicon carbide"Kei te noho ko" te "kaitiaki pakari" o ngā paipa ahumahi nā ōna āhuatanga ahurei.
Tērā pea ētahi e hiahia ana ki te mōhio he aha te arai uku silicon carbide? He arai uku tēnei i hangaia mai i te silicon carbide hei rauemi matua, ā, i tukatukahia mā roto i ngā tikanga motuhake, ka taea te piri pai ki te pakitara o roto o ngā paipa whakarewa, ka hanga he paparanga "pūeru tiaki". He rerekē ki ngā arai whakarewa, kirihou rānei noa, ko ngā āhuatanga o ngā uku silicon carbide tonu e hoatu ana ki tēnei paparanga "pūeru" ngā painga kāore e taea te whakataurite e ngā rauemi noa.
Tuatahi, he tino mīharo tōna "kaha ārai-kakahu". Ina kawehia ngā rauemi kei roto ngā matūriki mārō pērā i te paru o te konganuku, te paura waro, me ngā toenga para, ka ngawari te memeha o te pakitara o roto o ngā paipa noa i ngā matūriki, ā, ka angiangi haere. Heoi, he tino teitei te pakeke o ngā uku silicon carbide, tuarua ki te taimana, ka taea te ātete ngāwari ki te waku me te pānga o ngā matūriki, ka roa ake te roa o te mahi a ngā paipa. He maha ngā kamupene kua whakamahi i tēnei mea kua pūrongo mai i muri i te tāutanga o te arai uku silicon carbide, kua roa ake te huringa whakakapinga paipa i ngā wā maha i whakaritea ki mua, ā, kua tino whakaitihia te auau tiaki.
Tuarua, ka taea e ia te aro atu ki ngā wero o te waikura me te pāmahana tiketike. I roto i ngā ahumahi pēnei i te matū me te whakarewa, he maha ngā matū waikura kei roto i te reo e haria ana e ngā paipa pēnei i ngā matū waikawa me ngā matū kawakore, ā, ka noho pea i roto i ngā taiao pāmahana teitei. Ka ngawari te waikura, te whakapē rānei i ngā rauemi noa nā te pāmahana teitei. He tino pai te pumau matū o ngā uku karawiti silicon, kāore e wehi i te waikura waikawa me te kawakore, ā, ka taea te pupuri i te mahi pumau i ngā pāmahana teitei o te rau nekehanga Celsius. Ahakoa i raro i ngā āhuatanga mahi uaua mō te wā roa, ka taea e rātou te pupuri i ngā pānga tiaki pai.
He mea nui ake, ka whakatauritehia hoki e tēnei arai te whaihua me te ōhanga. He māmā noa iho tōna taumaha, ā, kāore e nui rawa te taumahatanga ki te paipa. He māmā noa iho hoki te tukanga tāutanga, ā, kāore he take ki te hanga whakarerekētanga nui ki te hanganga paipa taketake. Ahakoa he paku teitei ake te haumitanga tuatahi i tērā o te arai noa, i te wā roa, ka taea e tōna roanga mahi me te iti rawa o ngā utu tiaki te penapena i te maha o ngā whakapaunga mō ngā umanga, ka nui ake te whai hua.
I ēnei rā, me te pikinga ake o te hiahia mō te pono o ngā taputapu me te ōhanga i roto i te hanga ahumahi, kei te haere haere te whakamahinga whānui o te arai uku silicon carbide i roto i te maina, te matū, te hiko me ētahi atu mara. Kāore he mātāpono uaua, he mahi whakahirahira rānei, engari mā te mahi whai hua, ka whakatauhia te raruraru "tawhito me te uaua" o ngā paipa ahumahi, ka noho hei āwhina nui mō ngā umanga ki te whakaiti i ngā utu, ki te whakanui ake i te pai, me te whakarite i te pumau o te hanga. I te heke mai, me te arotau tonu o te hangarau, e whakaponohia ana ka nui ake te mahi a tēnei 'rauemi tiaki matua' ki te tiaki i te whanaketanga ahumahi.
