Whakaahuatanga Maka Hangaia o te Silicon Carbide
He mea tino nui ngā pereki silicon carbide hei hanga rauemi ātete-wai mō ngā oumu me ngā oumu maha i roto i te pāmahana tiketike me te kaha o te hau ero. He tino pai te mahi a ngā pereki ātete-wai silicon carbide ki te ātete ki te ero kino o te taiao, pērā i te kawe wera nui, te ātete pai ki te karawarawa, te ātete nui ki ngā ru wera, te ātete kaha ki te ero waikawa me te kawakore me te iti o te tauwehenga whānui wera. Ko te mea whakarewa silicon carbide ātete-wai ka whakamahia mō ngā wāhanga rerekē o te oumu sima me te tuanui o te oumu pewa hiko me te rīpene maitai.
Ngā Āhuatanga o te Silicon Carbide Castable
- Te kawe wera teitei,
- Te kaha o te pāmahana teitei,
- He ātete pai ki te pakū,
- He ātete pai ki te ru wera,
- He ātete kaha ki te waikura,
- Tauwehenga whānui iti.
Te Tukanga Hanga o te Silicon Carbide Castable
He mea hanga te pereki silicon carbide i te rauemi mata o te SiC pango. Ko te wāhanga tioata matua ko te SiC. Ka hangaia te pereki silicon carbide ātete mā te taurite i te kaihoko here, te whakaranu, te hanga me te tukanga tahu. Ko te pakeke o te pereki silicon carbide he 9, nō reira, he kaha te ātete o te pereki silicon carbide ki te para waikawa.
Ngā Hanganga o te Silicon Carbide Castable
Ko ngā rauemi mata o ngā pereki silicon carbide he silicon carbide, tata ki te 72%-99%. Ka kiia hoki te silicon carbide ko te moissanite, te onepū corundum, te onepū ātete rānei. Ka hangaia ngā pereki ātete silicon carbide mā te onepū quartz, te petroleum coke, te waro uku rānei, me ngā wahi rakau, ka puta mā te whakarewa pāmahana teitei i roto i te oumu ātete hiko.
Te Whakarōpūtanga o te Silicon Carbide Castable
Ka taea te whakarōpū i ngā pereki ātete warowaihā konukōre ki te uku, ki ngā pereki warowaihā konukōre ki te Si3N4, ki ngā pereki warowaihā konukōre ki te Sialon, ki ngā pereki warowaihā konukōre ki te β-SiC, ki ngā pereki warowaihā konukōre ki te Si2ON2 me ngā pereki warowaihā konukōre ki te karaihe anō.
