Apo Keramika Alumina Precision no ke Sila ʻana, ka Hoʻokaʻawale ʻana a me ka Hoʻopaʻa ʻana
Ua hana pololei ʻia ke apo keramika a St.Cera mai ka 99.8% alumina maʻemaʻe kiʻekiʻe (Al₂O₃) no nā noi e pono ai ke kūpaʻa kiʻekiʻe i ka ʻaʻahu, ka insulation uila, a me ke kūpaʻa wela a hiki i ka 1600°C. Kākoʻo kā mākou hiki ke hana i nā diameters waho a hiki i ka 600mm, ka mānoanoa a hiki i ka 100mm, a me nā diameters o loko e like me ka liʻiliʻi e like me 0.2mm, me ka pālahalaha o 0.003mm, parallelism o 0.002mm, a me ka concentricity o 0.01mm. Loaʻa ma ke ʻano he apo sila, nā apo spacer, nā apo paʻa, a i ʻole nā kikona maʻamau. ʻO ka porosity ʻole o ka mea a me ka inertness kemika e kūpono ia no nā kemika aggressive a me nā wahi plasma.
Nā kikoʻī (ma muli o 99.8% Al₂O₃& nā hiki ke hana ʻo St.Cera):

Nā noi:
- · Nā apo sila mīkini i loko o nā pamu a me nā mea hui
- · Mea hoʻokaʻawale a me nā apo paʻa i nā mea hoʻopaʻa semiconductor
- · Nā apo hoʻokaʻawale uila i nā lako uila kiʻekiʻe
- · Nā apo sila o ke keʻena hakahaka (me ka gasket kūpono)
Ka pololei o ka hana ʻana:
Pololei: 0.005mm, perpendicularity: 0.005mm, roundness: 0.002mm, i hōʻoia ʻia e CMM.
Nā Pōmaikaʻi:
- · ʻAʻole magnetic, ʻaʻole alakaʻi, kūpaʻa i ka pala
- · ʻAʻohe hanauna ʻāpana - kūpono no ka hoʻohana ʻana i ka lumi maʻemaʻe
- · Mālama i ke kūpaʻa o ka dimensional ma lalo o ka thermal cycling
Hoʻopilikino ʻana:
Loaʻa nā ʻāpana kea maʻamau (ʻano huinahā, huinahā, ʻanuʻu), nā lua hoʻopaʻa, a me nā notches e pili ana.
