Kaiwhakaputa Mutunga Ukume Alumina me ngā Hongere Korehau Whakauru
Ka whakauruhia e te miihini mutunga korehau alumina a St.Cera ngā hongere korehau kua oti te mīhini me ngā kōhao momi tika ki roto i te tinana alumina tino parakore 99.8%. Ka whakakorehia e tēnei hoahoa ngā papa korehau o waho, ka taea ai te tango tika i te wafer me te kaha pupuri ōrite. Mā te kaha piko teitei o te rauemi (361 MPa) me te pakeke (16 GPa) ka mau te pumau o te taha mō te wā roa i raro i ngā huringa korehau maha. Ka mau tonu te papatahi puta noa i te rohe papa i roto i te 10 μm, ka ārai i te ahotea me te pakaru o te wafer. Kei te flange whakapuru o muri ngā tauranga korehau hei whakauru ngāwari ki ngā ringa karetao OEM.
Ngā Whakatakotoranga(i runga i te 99.8% Al₂O₃):
| Taonga | Uara |
| Rauemi | 99.8% Arumina (Ai) |
| Kiato | 3.93 karamu/cm³ |
| Kaha Whakapiko | 361 MPa |
| Te Pakari o Vickers | 16 GPa |
| Te Tauwehenga o te Rangatahi | 380 GPa |
| Whakawhanuitanga Wera | 7.2×10⁻⁶/℃ |
| Papatahi o te Papa | ≤10 μm |
| Whānui o te Hongere Korehau | 0.5–2.0 mm |
| Te Mahana Whakahaere Mōrahi | 800°C |
Ngā tono:
● Te tango korehau i ngā anga angiangi, i ngā anga piko rānei
● Te whakahaere tika i te anga, me te kore e mau ki te taha
● Whakawhiti pūtau rā me te papa LED
Te Hanga:
Te keri i te pārae alumina kua whakatōkia → Te keri CNC tuaka-5 o ngā awa me ngā kōhao korehau → te whakakī mata → te horoi ultrasonic → te whakamātautau turuturu herium. Kua whakamātauhia te rere o ia mea whaihua kia ōrite te korehau.
Ngā Painga:
● Kāore he papa korehau o waho (ka whakaiti i ngā pūtake matūriki)
● Ka ārai te pēhanga pupuri ōrite i te tohu wafer
● He ngoikore ngā matū, ā, he hototahi ki te rūma ma
