製品の詳細

デザインの特徴
アルミナセラミックリング(高温耐性圧力耐性ブッシング、高周波工業用セラミックリング)は、高純度アルミナから作られています。 

材料、優秀な機械および熱特性を表わします。第一に、これらの製陶術は非常に高い硬度および圧縮強さを所有しています 

(硬度82ロックウェル、圧縮強度最大2000 MPa)により、極端な条件下でも形状と寸法の安定性を維持することができます。 

二つ目に、極めて低い吸水率(0%)と空気透過率(0%)により、湿気の多い環境でも優れた性能を発揮します。さらに、 

よい熱伝導性および熱衝撃の抵抗(熱伝導性27.5 W/(m·K)、熱衝撃の抵抗ΔT℃200)は安定した操作を可能にします 

容易に傷つくことのない高温環境。

これらのリングは比較的低い熱膨張係数(7.6 x 10-6/℃)を持ち、温度変化による膨張と収縮が最小限に抑えられます。 

精密な次元制御を要求する適用のために有利であるかどれが。電気特性の点では、アルミナの製陶術は優秀な電気絶縁材を表わします 

体積抵抗率が10Ω・cmと高く、電気絶縁やその他の要求の厳しい電気用途に適しています。

アプリケーション領域

アルミナの陶磁器リングはさまざまなデマンドが高い産業分野で広く利用されています。航空宇宙空間では、最高に対して抵抗力がある部品を製造するのに使用されています 

例えばエンジン部品や熱保護システムなどの温度や圧力。半導体製造では、これらのリングがよく使用されています。 

装置のための部品を絶縁し、高温や電磁干渉から敏感な電子部品を保護します。さらに、 

高周波特性により、これらのリングはレーダーや通信などの高周波電子機器にも適しています。 

装置だ

エネルギー産業、特に原子力および太陽エネルギーでは、アルミナセラミックスが重要な構造材料および絶縁材料として使用されています。 

高温安定性と放射線耐性があります。また、高い化学耐性と耐摩耗性があるため、広く使用されています。 

例えばポンプ、バルブ、センサーなどの化学および鉱業の装置。
