I roto i ngā mahi ahumahi o ēnei rā, he maha ngā tukanga kāore e taea te mahi me te kore he taiao pāmahana teitei, nō reira ko te huarahi ki te whakarato wera me te whai hua me te pumau kua noho hei take matua.Ngā ngongo irahiko nui o te silicon carbidekei te puta haere mai hei momo huānga whakamahana ahumahi hou, e kawe mai ana i ngā otinga pai ake ki ngā ahumahi maha. I tēnei rā, ka haria koe e tēnei tuhinga ki tētahi māramatanga hohonu ake mō ngā ngongo irahiko nui o te silicon carbide.
He aha te ngongo irahiko nui o te silicon carbide?
Ko te ngongo irahiko nui o te silicon carbide, i roto i ngā kupu māmā noa, he wāhanga nui i hangaia mai i te rauemi silicon carbide e whakamahia ana hei whakawhiti wera i roto i ngā oumu ahumahi me ētahi atu taputapu. He rite ki te "karere wera" o te oumu ahumahi, e tuku ana i te wera ki te wāhi e hiahiatia ana. Ko te arotahi a Shandong Zhongpeng ki te rangahau me te hanga i ngā uku silicon carbide kua tauhohengahia. He painga motuhake tō ngā ngongo irahiko nui o te silicon carbide i hangaia mā tēnei tukanga:
Ngā Painga o te Ngongo Irahiko Ukume Silicon Carbide Sintering Tauhohenga
1. Te ātete tino pai ki te pāmahana teitei: I raro i te taiao pāmahana teitei, ka taea e ngā rauemi noa te whakapēhea me te pakaru, engari ko ā mātou ngongo hihi uku silicon carbide kua whakapūmauhia ka taea te "pūmau pērā i a Mount Tai". Ka taea e ia te tu atu i ngā pāmahana tino teitei, ā, i roto i te hau waikura, ka taea e te pāmahana whakamahinga roa te eke ki te 1350 ° C. Ko te tikanga o tēnei ka taea te mahi pumau i roto i ētahi tukanga whakaputa ahumahi e hiahia ana ki ngā pāmahana teitei (pēnei i te whakarewa maitai, te tahu uku, me ētahi atu), e whakarite ana i te haere tonu o te whakaputa me te whakaiti i ngā ngaronga wā kore e puta mai i ngā rahunga taputapu.
2. Te kawe wera tino pai: He pānga nui te pai o te whakawhiti wera ki te pai me te whakapaunga pūngao o te whakaputanga ahumahi. He tino teitei te kawe wera o te rauemi silicon carbide, e āhei ai tā tātou ngongo irahiko ki te whakawhiti tere i te wera. Pērā i te huarahi maeneene, ka taea e te wera te tere tae atu ki tōna ūnga. Ki te whakatauritea ki ētahi rauemi tuku iho pērā i ngā ngongo irahiko, ka taea e ia te tere ake te wera o ngā oumu ahumahi, te whakapoto i ngā huringa whakaputa, me te whakaiti i te whakapaunga pūngao nā te mea he pai te whakawhiti wera, ka penapena utu mō ngā umanga.
3. Ātete tino waikura: He maha ngā taiao i roto i te hanga ahumahi he waikura, pērā i ētahi tukanga hanga matū e whakaputa ana i ngā hau me ngā wai waikura. Ko te ngongo irahiko uku silicon carbide kua whakakorikoria, me ōna āhuatanga matū pumau, ka taea te ātete pai i ēnei waikura, ka roa ake te roa o te mahi a te taputapu. Ko ētahi ngongo irahiko whakarewa he ngawari ki te waikura me te pakaru i roto i ngā taiao waikura, me whakakapi pinepine. Ka taea e ā mātou ngongo irahiko silicon carbide te whakaiti i te auau tiaki me te whakakapinga, ka whakapai ake i te pai o te whakaputa.
He whānui te whakamahinga i roto i ngā mara maha
Kua whānuitia te whakamahinga o ngā ngongo irahiko nui o te silicon carbide i roto i ngā momo mara nā ō rātou painga maha. Ka whakamahia i roto i te mara o ngā oumu ahumahi mō ngā taputapu oumu, me te ahumahi matū mō ngā tukanga e hiahia ana ki ngā tauhohenga pāmahana teitei.
Ko ngā ngongo irahiko nui o te silicon carbide, me ōna painga o te ātete ki te pāmahana teitei, te kawe wera pai, te ātete ki te waikura, me te ātete ki ngā ru wera, kei te kawe mai i ngā otinga whai hua, pumau, me te penapena hiko ki te whakaputa ahumahi. Me te haere tonu o te whanaketanga me te auahatanga o te hangarau, e whakapono ana mātou ka nui ake te mahi a tēnei i roto i te whanaketanga ahumahi a meake nei, ka werohia he kaha hou ki te whanaketanga o ngā momo ahumahi. Mena kei te hiahia koe ki ā mātou ngongo irahiko nui o te silicon carbide, tēnā koa whakapā mai ki a mātou i ngā wā katoa kia tūhuratia ai ētahi atu mea ka taea.
