Kāore te silicon carbide i whakakorikoria ki te pēhanga hauhautanga e whakamahia noa ana hei mea whakakorikori, engari hei rauemi hou, ā, e whakamahia whānuitia ana i roto i ngā hua hangarau teitei, pērā i ngā uku i hangaia mai i ngā rauemi silicon carbide. Nā, he aha ngā painga e ono o te silicon carbide i whakakorikoria ki te pēhanga hauhautanga me te whakamahinga o ngā uku silicon carbide?
E ono ngā painga o ngā rauemi silicon carbide kua whakakikoruatia ki te pēhanga hauātea:
1. Te iti o te mātotoru
He iti ake te mātotoru o te rauemi silicon carbide i tō te konganuku, ā, ka mama ake te taputapu.
2. Ātete ki te waikura
He teitei te ira rewa o te rauemi silicon carbide, he ātete ki te werawera, ā, he ātete ki te ru wera. Ka whakamahia te silicon carbide i roto i ngā mea whakakoi, ngā oumu uku, ngā mea para silicon carbide, ā, ka taea te whakamahi i roto i te umanga whakarewa me te whakarewa me te oumu whakahoro poutū, pereki, arai pūtau hiko konumohe, tungsten, oumu iti me ētahi atu hua uku silicon carbide.
3, pāmahana teitei, ka whakaitihia te tauwehenga whakawhānui wera
Ka hangaia te rauemi karawiti silicon i ngā pāmahana teitei. I ētahi taiao pāmahana teitei, me whai rauemi e hiahia ana ki te kaha tukatuka me te tika tukatuka e taea ai e ngā uku karawiti silicon te whakatutuki. Ko te pāmahana teitei o te karawiti silicon he tata ki te 800, ā, ko te pāmahana o te maitai he 250 noa iho. Mā te tatau ā-whāwhā, ko te tauwehenga whānui wera toharite o te karawiti silicon i roto i te awhe 25 ~ 1400 he 4.10-6 /C. Ka inehia te tauwehenga whānui wera o te karawiti silicon, ā, e whakaatu ana ngā hua he iti ake te nui i ērā atu mea whakakoi me ngā rauemi pāmahana teitei. Karawiti silicon kua whakakorikoria i raro i te pēhanga hau.
4, te kawe wera teitei
He teitei te kawe wera o ngā rauemi silicon carbide, he āhuatanga nui anō tēnei o ngā āhuatanga ā-tinana o te silicon carbide. He nui ake te kawe wera o te silicon carbide i ērā o ētahi atu refractories me ngā abrasions, tata ki te 4 ngā wā i tērā o te corundum. He iti te tauwehenga whānui wera o te silicon carbide, ā, he teitei te kawe wera, nō reira ka iti ake te ahotea wera o te mea mahi i te wā e whakamahana ana, e whakamatao ana hoki. Koia te take he tino ātete ngā wāhanga SiC ki te ru.
5, kaha ā-mīhini teitei, pakari pai
He tino teitei te kaha ā-pūkaha o te rauemi silicon carbide, ā, ka ārai i te hurihanga o te rauemi. He nui ake te kaha ā-pūkaha o te silicon carbide i te corundum.
6, he pakeke teitei me te ātete kakahu
He tino teitei te pakeke o ngā rauemi silicon carbide, ā, ko te pakeke o te Moss gap he 9.2~9.6, tuarua noa iho i te taimana me te tungsten carbide. Ki te whakatauritea ki ngā rauemi maitai whakarewa, he tino pakari, he iti te tauwehenga o te waku, he iti te waku, he iti te taratara o te mata, ā, he pai te ātete ki te kakahu me te kore he hinuhinu. Hei tāpiri, he ātete ki ngā matū o waho, ka whakapai ake i te manawanui o te mata. Ko te silicon carbide kua whakatōngia i raro i te pēhanga hau.
Te whakamahinga o ngā uku karāhe silicon carbide kua whakatōngia ki te pēhanga hauātea
1, te hanga rauemi silicon carbide o ngā uku motuhake
He rauemi pakeke te rauemi silicon carbide, he iti te utu, ka taea te whakaputa hua silicon carbide, pērā i ngā hiri silicon carbide, ngā ringaringa silicon carbide, ngā pereti ātete matā silicon carbide, ngā kōtaha silicon carbide, me ētahi atu, ka taea te whakamahi ki ngā hiri miihini me ngā momo papu. Karāhe silicon kua whakatōngia i raro i te pēhanga hau.
2, te hanga rauemi zirconia o ngā uku motuhake
He nui te kawe irahiko o te uku zirconia, he pai te pumau matū me te pumau hanganga, ā, kua whānuitia te rangahau me te whakamahi i te rauemi irahiko. Mā te whakapai ake i te tukanga hanga o te kiriata irahiko e hangai ana ki te zirconia, te whakaiti i te pāmahana mahi me te utu hanga o ēnei rauemi, me te whai kia tutuki te ahumahi he huarahi nui anō hoki mō ngā rangahau ā muri ake nei.
