Ko te nitride silicon (SiC) he onepū kiripaka, he kōka hinu kua whakapūkaratia (he whakapūkara waro rānei), he para rakau (me tāpiri tote te hanga o te nitride silicon matomato) me ētahi atu rauemi mata, mā te oumu whakamahana hiko tonu i te pāmahana teitei. Ko te mowhiti hiri nitride silicon he hua nitride silicon i hangaia mai i te rauemi silicon carbide. Nā, he aha ngā tono nui o te silicon carbide kua tauhohenga-whakapūkara me ngā āhuatanga o ngā hiri?
Ko te tono nui o te tauhohenga sintering silicon carbide:
1. Ko te whakamahinga o te umanga hua whakarewa ko te ātete wera o te silicon nitride, he kaha teitei, he kawe wera pai, he ātete pānga, he wera tonu i te pāmahana tiketike, he rauemi mata whakamahana ā-kore, pērā i te oumu wehewehe tāke. He paepae oumu whakatikatika, he pūtau hiko konumohe, he arai oumu rewa parahi, he pewa oumu paura konutea, he ngongo tiaki thermocouple, me ētahi atu.
2. Ko te whakamahinga o te umanga maitai he whakamahi i te whakairo o te silicon nitride. He ātete ki te ru wera, he ātete ki te pakū. Nā te pai o te kawe wera, ka whakamahia hei whakapuru i ngā oumu hanga rino nui me te rahi-waenga hei whakapai ake i te roa o te mahi.
3. Ko te kaha o te silicon nitride i roto i te umanga whakarewa he tuarua noa iho i te maitai koura, he kaha te ātete ki te kakahu, he kaha te ātete ki te kakahu, he teitei te ātete ki te kakahu o te paipa, te impeller centrifugal, te rūma papu, te mīhini hurihuri, te arai keri, he pai ngā rauemi mata, he pai te ātete ki te kakahu. Ko te roa o te ora o te kirihou he 5 ki te 20 ngā wā, ā, ko tētahi o ngā rauemi mata pai rawa atu mō ngā papa hākinakina rererangi.
4. Te whakamahinga o te tauwehenga whakawhiti wera i roto i te taumata whakaputa ahumahi o ngā rauemi hanga whakapaipai porcelain me ngā wahi wira onepu. Nā ngā āhuatanga o te wera hihi me te kaha o te kirika, ka taea e te whakaputa me te hanga o te oumu pepa whakarewa te whakaiti i te rahinga o te oumu, engari ka whakapai ake hoki i te rahinga rokiroki me te kounga hua o te oumu, me te whakaiti i te wā whakaputa, koinei te rauemi ā-kore tino pai mō te tahu i ngā tae uku.
5. He pai te kawe wera me te ātete wera o te whakawhiti wera, ā, ka penapenahia e te whakawhiti wera te 20%, te whakapaunga wahie 20%, te whakapaunga wahie 35%, ā, ka piki ake te pai o te whakaputanga mā te 20-30%. Ina koa, ko te ātete kakahu o te paipa tuku wai tuku i whakamahia i roto i te tipu tukatuka keri he 6 ki te 7 ngā wā i tērā o ngā rauemi whakarewa noa.
Ngā āhuatanga o te mowhiti hiri silicon carbide kua whakamātauhia-tauhohenga:
1, ātete wera
Nā ngā āhuatanga o ngā rauemi silicon nitride, he ātete teitei ki te pāmahana ngā hiri silicon nitride, ā, he rerekē ngā momo āhuatanga ātete wera o ngā tukanga rerekē. Ka taea te whakamahi i ngā hiri silicon nitride kua whakapakeketia mai i te 1300 nekehanga, ā, ka taea e ngā hiri silicon nitride kua whakawerahia kore-pēhanga te eke ki te 1600 nekehanga.
2. Ātete ki te waikura
Ka taea te whakamahi i te mowhiti hiri silicon nitride mai i te āhua waikawa kaha me te kawakore, ā, he uaua ki te whakaiti i te pānga hiri.
3, ātete kakahu
Ko ngā mowhiti hiri silicon carbide kua whakakorikoria-tauhohenga kia rite ki tētahi tukanga kāri, kia tino tika, kia maeneene hoki te mahere, me te ātete kakahu o ngā rauemi silicon carbide, ka taea te whakamahi i ngā mowhiti hiri silicon nitride ki te mirimiri tetahi ki tetahi. Kāore e ngāwari te whakaiti i ngā āhuatanga kino nā ngā āhuatanga pāmahana tiketike tonu.
4. Ngāwari
I te roa o te whakamahinga o ngā rauemi mata o te silicon carbide sintered, ka taea te huri hei momo tauira o te huruhuru hipi, te tukatuka tuarua, kia hiahia ai ngā kaihoko ki ngā taonga.
