Pū Whakamahana Ukume 99% Alumina Pū Whakarewa Hau Wera Matua Whakamahana
Pū Whakamahana Ukume 99% Alumina Pū Whakarewa Hau Wera Matua Whakamahana
Ko ngā wāhanga uku alumina he momo rauemi uku he mea hanga mai i te alumina parakore teitei (Al₂O3), he tino pakeke, he ātete ki te kakahu, he ātete ki te pāmahana teitei, ā, he pumau matū. He whānuitia te whakamahinga i roto i ngā mara ahumahi maha, ā, koinei te rauemi uku ahumahi nui rawa atu me te nuinga e whakamahia ana i runga i te rahinga whakaputa.

1. Te pakeketanga teitei me te ātete ki te kakahu
Ko te pakeketanga Mohs o ngā uku alumina he rite ki te taumata 9, ko te tuarua anake ki te taimana. Ātete kakahu: Ko tōna ātete kakahu he 266 ngā wā i te maitai manganese, ā, he 171.5 ngā wā i te rino maka chromium teitei.
2. Te ātete pāmahana teitei me te pumau wera
Ātete pāmahana teitei: Ko te ira rewa o ngā uku alumina he teitei ki te 2050 ℃, ā, ka taea te pupuri i te mahi pumau i te pāmahana teitei o te 2000 ℃. Te pumau wera: He iti te tauwehenga o te whakawhānui wera, ā, ka taea te pupuri i te pumau hanganga i raro i ngā huringa pāmahana tino nui.
3. Hoahoa mama Kiato:
Ko te matotoru o ngā uku alumina he 3.6-3.8g/cm³ anake, he mama ake i te maitai neke atu i te 50%. Hei tauira, mā te whakamahi i ngā wāhanga uku alumina i roto i ngā waka rererangi ka taea te whakaiti i te taumaha mā te 30% me te whakapai ake i te pai o te whakamahinga o te wahie.
4Ātete ki te waikura me ngā āhuatanga whakamahana Ātete ki te waikura:
He ātete tino pai ki ngā waikawa kaha, ngā kawakore, me ngā mea tote, he pai mō ngā tauhohenga matū, ngā takirere ārai-waikura, me ētahi atu. Āraitanga: Me te ātete o ≥ 1 × 10 ¹⁴Ω· cm, koinei te rauemi pai mō ngā papa taputapu hiko auau-teitei.
5. Te whai huatanga nui o te utu Te whai huatanga o te utu:
Nā te roa o te ora me te iti o ngā āhuatanga tiaki ka tino whakaitihia ngā utu mō te wā roa.
- Ngā uku ā-mīhini me ngā uku hanganga:e whakamahia ana mō ngā peera, ngā reti, ngā hiri, me ētahi atu, hei whakaiti i ngā rahunga me te wā kore mahi.
- Ngā ahumahi matū me te pāmahana teitei:e whakamahia ana hei rauemi ātete ahi, hei rauemi whakamahana, hei arai tauhohenga matū, me ngā hononga paipa.
- Hikohiko/Mana:Whakamahia mō ngā papa hiko, ngā ringaringa whakamahana, me ētahi atu, e whakarato ana i te mahi whakamahana teitei.
- Hauora:Whakamahia mō ngā hononga horihori, ngā tāpiringa niho, me ētahi atu, he tino hototahi ki te koiora.
- Rererangi:Whakamahia mō ngā wāhanga miihini, ngā mata tāpoi, me ētahi atu, hei whakarei ake i te pono o ngā pūnaha hiko
