Pereki Kōrunuma
Pereki korunumaHe hua ātete-kaha te mahi, ko te korundum te wāhanga matua o te tioata, e whakamahia whānuitia ana i roto i ngā mara ahumahi pāmahana-tiketike. E paingia ana e ngā momo ahumahi nā te mea he tino ātete ki te pāmahana-tiketike, he kaha miihini, he pumau matū hoki. Kei raro nei he whakataki taipitopito ki ā mātou pereki korundum, tae atu ki te whakarōpūtanga hua, ngā āhuatanga mahi, te hanganga matū, ngā mara tono me ngā painga hua.
Whakarōpūtanga Hua
E ai ki te hanganga matū (ngā wāhanga tuarua kua tāpirihia) me ngā pūtake rauemi mata, e whā ngā wāhanga matua o ngā pereki korundum, ia wāhanga he āhuatanga ahurei me ngā horopaki tono kua whakaritea hei whakatutuki i ngā hiahia ahumahi rerekē.
1. Pereki Kōrunuma Mā
Ngā Kupu Matua:Teitei o te Parakore, te Iti o te Parakore, te Mahana-Tiketike
Ngā Āhuatanga Kaha:He mea hanga mai i te alumina ahumahi, he tino iti te poke (ina koa he iti te waikura rino), nō reira he mā. He tino kaha ki te mura ahi, he kaha hoki ki te pāmahana teitei, me te pumau matū pai rawa atu i waenga i ngā pereki korundum.
Ngā Ihirangi Al₂O₃:≥ 99%
2. Pereki Kōrunuma Parauri
Ngā Kupu Matua:Whai hua te utu, Whānui te whakamahinga, Ārai i te pakaru
Ngā Āhuatanga:I whakarewaina mai i te bauxite i roto i te oumu hiko, kei roto he iti noa te waikura rino (e whakaatu ana i te parauri). He hanganga matotoru, he ātete pai ki te pakaru, ā, he pai ake te utu ki te pereki korundum mā.
Ngā Ihirangi Al₂O₃:≥ 95%
3. Pereki Kōrumumu Chrome
Ngā Kupu Matua:Ātete ki te Waikura, Umu Karāhe, Umu Sima
Ngā Āhuatanga:Ka tāpirihia te chromite, te chromium oxide rānei ki te corundum. Ko tōna āhuatanga nui ko te ātete tino kaha ki te rewa karāhe me te horo o te para, me te ātete pai ki ngā ru wera i te wā kotahi.
Ngā Ihirangi Al₂O₃:90-95%
4. Pereki Kōrunuma Zirconia
Ngā Kupu Matua:Ātete ki te Kakahu, Te Pūmautanga o te Ru Wera, Te Pakitara Ouma Karāhe
Ngā Āhuatanga:Ka tāpirihia te zircon. Mā te tāpiri i te wāhanga zircon ka tino whakapai ake i te ātete o te rauemi ki te kakahu me te pumau o te ru wera (te ātete ki te whakamatao tere me te wera).
Ngā Ihirangi Al₂O₃:60-80% (+ ZrO₂)
Ngā Āhuatanga Mahi:
He rauemi ātete-kaha te mahi a ngā pereki kōrunamu, ā, he maha ngā āhuatanga pai o ngā pereki kōrunamu, ā, ka whakarei ake ngā momo pereki kōrunamu i te mahi kua whakaritea i runga i ngā āhuatanga o runga ake nei:
1. Teitei o te Ātete:Ka taea e te ātete te eke ki runga ake i te 1750℃, ā, ko ētahi hua parakore teitei (pērā i te pereki korundum mā) ka taea te tu atu i ngā pāmahana teitei mō te wā roa ki runga ake i te 1800℃, kia mau tonu ai te pumau i roto i ngā taiao pāmahana teitei me te kore e rerekē te āhua, e pakaru rānei.
2. Kaha Teitei:He kaha te pēhi i te pāmahana rūma, tae atu ki te 340MPa, ā, ka taea e ia te tu atu i ngā kawenga miihini i ngā pāmahana teitei. I roto i ēnei, he tino kaha te pereki korundum mā ki te pāmahana teitei.
3. Te Pūmautanga Matū Pai:He kaha tōna ātete ki te para waikawa, te para kawakore rānei, ngā konganuku, te rewa karāhe, me ētahi atu, ā, ehara i te mea ngāwari ki te pāngia e ngā tauhohenga matū. Ko te pereki kōrunuma mā te mea tino pumau te matū nā tōna parakore teitei.
4. Ātete Para Pai rawa atu me te Ātete Horoi:He tino kaha te ātete ki ngā para rewa waikawa, kūpapa me ētahi kawakore. He tino pai te mahi a te pereki kōruma chrome i roto i tēnei mahi, ā, ka taea te whakaroa i te roa o te mahi.
5. Te Pūmautanga Pai o te Ru Wera:Ahakoa kāore i te rite te pai ki ētahi rauemi kei roto he silicon, he konupūmā rānei, ka taea te whakapai ake mā te tāpiri i te zircon (pērā i te pereki zirconia corundum) mā te whakarerekē rānei i te nekehanga o ngā matūriki. He pai ake te pumau o te pereki zirconia corundum ki te ru wera.
Pereki korundum-mulliteHe hua ātete āhua kounga teitei tēnei, ko te korundum me te mullite ngā āhua matua o te tioata. Nā te kaha o ngā āhua matua e rua, ka honoa te ātete pāmahana teitei me te ātete waikura o te korundum ki te pumau o te ru wera o te mullite. E mōhiotia whānuitia ana tēnei hua i roto i ngā mara ahumahi pāmahana teitei o te ao pērā i te whakarewa, te karāhe, ngā matū hinu, me te hanga pango waro, e whakarato ana i ngā otinga whakapuru pono mō ngā wāhanga oumu matua, ā, ka whakapai ake i te pai o te mahi taputapu me te roa o te ratonga.
Ngā Painga Matua mō te Mahi:
1. Ātete tino pai ki te ru wera:Koinei tōna painga matua. He iti te tauwehenga whakawhanui wera o te Mullite, ā, ka mimiti te hanganga tioata āhua-ngira i te ahotea i puta mai i ngā piki me ngā heke o te pāmahana, ka whakaiti nui i te pakaru i puta mai i te whakamatao tere me te whakamahana i ngā pāmahana teitei. He nui ake tōna mahi i ngā pereki korundum parakore.
2. Kaha taurite me te ātete ki te waikura:Mā te noho mai o te wāhanga korundum ka tino kaha i ngā pāmahana rūma me ngā pāmahana teitei, ā, ka pai hoki te ātete ki te para waikawa, te karāhe rewa, me ētahi atu mea. Ahakoa he iti ake te ātete ki te kawakore i ērā o ngā pereki korundum kōroma, he whānui ake ngā whakamahinga.
3. Te kawe wera ngawari:Ki te whakatauritea ki ngā pereki korundum matotoru, he iti ake te kawe wera me te pupuri tonu i tētahi taumata whakamarumaru, ka whakaiti i te ngaronga wera i roto i ngā taputapu pāmahana teitei, ā, he pai hoki mō ngā tono e hiahia ana ki te whakamarumaru wera.
