I roto i te maha o ngā wheketere, ka tūpato ētahi paipa i ngā āhuatanga mahi tino uaua: te pāmahana teitei, te waikura kaha, me te kakahu nui. Koinei ngā 'uaua toto ahumahi' e whakarite ana i te whakaputa tonu me te pumau. I tēnei rā ka kōrero tātou mō te mea tino pai i roto i tēnei momo paipa –paipa uku silicon carbide.
He maha ngā tāngata e whakaaro ana ki te kupu "pakari" ina rongo rātou i te kupu "uku". Engari ko ngā uku silicon carbide ahumahi e whai ana i te "pakeke" me te "pūmautanga" tino pai. He tino teitei tōna pakeke, ā, he nui atu tōna ātete ki te kakahu i ērā o ngā konganuku me te rapa. Ka taea e ia te tu atu ki te horo wai tere tere kei roto ngā matūriki totoka mō te wā roa; He tino pumau ngā āhuatanga matū, ā, ka taea te tu atu ki te horo o ngā waikawa kaha, ngā turanga kaha, me ngā tote; I te wa ano, ka taea e ia te mahi pumau i ngā pāmahana teitei me te tu atu ki ngā pāmahana tae atu ki te 1350 ℃. Hei tāpiri, he pai te kawe wera me te mata maeneene, e āwhina ana ki te whakaiti i te ātete kawe me te whakapau kaha.
I roto i ngā kupu māmā noa iho, kua hangaia ngā ngongo uku silicon carbide hei whakaoti rapanga kawe o te "wera, te whakakoi, me te waikura". I roto i te kawe i te para me te moata i roto i ngā ahumahi pēnei i te keri, te whakarewa, me te mana wera, ka taea e ia te whakaroa ake i te roa o te mahi a ngā paipa me te whakaiti i te wā kore mahi mō te whakakapinga; I roto i te kawe i ngā rauemi waikura i roto i ngā ahumahi matū me te tiaki taiao, ka taea e ia te whakarite kia roa te mahi pumau me te whakaiti i te tūponotanga o te turuturu. Ahakoa he nui ake te haumitanga tuatahi, he nui ngā painga roa mai i te tirohanga whānui o te whakaiti i te tiaki, te whakaiti i te whakapaunga pūngao, me te whakarite i te whakaputanga.
He mahi uaua te hanga i ngā ngongo uku silicon carbide. I te nuinga o te wā, ka konatunatua te paura silicon carbide ki tētahi iti o ngā tāpiringa hei hanga i tētahi "tinana matomato" me tētahi kaha, kātahi ka whakakāhia ki te pāmahana teitei hei hanga i te rauemi kia matotoru, kia mārō hoki. E ai ki ngā hiahia rerekē, ka whakamahia ngā tukanga rerekē pēnei i te whakakānga tauhohenga me te whakakānga kore pēhanga. Hei ngāwari ake te tāutanga, ko ngā paipa kua oti te whakaoti he mea hono ki ngā wāhanga pēnei i ngā flange whakarewa.
Ahakoa tōna mahi pai rawa atu, he rauemi uku tonu ngā ngongo uku silicon carbide e hiahia ana kia "māmā te tiaki" ina whakamahia. Me tino tupato te tāutanga me te kawe kia kore ai e pā kino; Me whakarite kia nui te tautoko me te utu whakawhanui wera kia kore ai e nui ake ngā kawenga e puta mai ana i te ahotea o waho, i ngā huringa pāmahana rānei; I mua i te whiriwhiri i ngā rauemi, he pai ake kia arotakehia e te miihini ngaio te reo, te pāmahana, me te pēhanga motuhake kia kitea ai te otinga tino tika.
I te nuinga, kua tutuki i ngā ngongo uku silicon carbide te taumata "pakeke" me te "pūmautanga", e whakarato ana i ngā otinga pono mō ngā āhuatanga kawe tino uaua, ā, ko rātou tonu ngā "toa ngaro".
