인듐 진공 씰

인듐 진공 씰 헬륨 밀폐형 씰, 브리징 금속 및 유리 및 세라믹과 같은 비금속 기판을 만들기 위한 우수한 소재로 돋보입니다. 그 다용성은 극저온 환경, 진공 펌프 및 열에 민감한 영역으로 확장되어 안정적인 봉쇄를 보장합니다.

인듐이 실런트 역할을 할 때, 다른 개스킷 재료의 단순한 장벽 형성과는 달리 연결 표면과 화학적 결합을 시작합니다. 특히, 인듐 씰은 기계적 충격, 진동 및 극한 온도에 대한 복원력을 보여 까다로운 응용 분야에 없어서는 안 될 요소입니다.

인듐의 고유한 특성은 표면에 산화막을 형성하는 경향입니다. 기판과 깨끗한 결합을 형성하려면 이 필름이 압축 및 소성 변형을 통해 파괴되어야 합니다. 인듐의 전성에 의해 촉진되는 이 공정은 극저온에서도 쉽게 발생하여 효과적인 밀봉을 보장합니다.

The quality of an 인듐 인감 hinges upon several factors:

1. 순수함과 청결함: 일부 응용 분야에서는 99.999% 인듐 순도를 요구하지만 최적의 인듐 순도 수준인 99.99%가 선호됩니다. 오염물질, 특히 유기화합물은 탈지를 통해 제거해야 합니다. 표면 산화물은 50% 염산에 잠깐 담근 후 탈이온수로 헹구면 제거될 수 있습니다.
2. 표면 준비: 모든 표면은 철저한 청소와 건조를 거쳐야 합니다. 유리 및 세라믹 표면은 크롬산과 황산으로 처리한 후 염산과 탈이온수로 헹궈야 합니다. 인듐 금속 표면은 노출되지 않거나 인듐으로 사전 주석 도금되거나 인듐 또는 은으로 도금될 수 있습니다. 표면 마무리는 과도한 연마나 연마 변형 없이 주의 깊게 수행되어야 합니다.
3. 인듐의 두께와 모양: 인듐 씰의 두께는 표면적과 압축력에 따라 달라집니다. 인듐 'O' 링 홈 응용 분야에서 인듐 씰은 압축 시 홈 크기를 5-15% 초과해야 합니다. 인듐의 겹치는 부분은 특정 시나리오에서 연속 와셔를 대체할 수 있습니다. 잘 형성된 씰은 2 x 10-7 torr x 리터/초 미만의 누출률을 나타냅니다.

인듐 선택, 표면 준비 및 밀봉 구성에 대한 세심한 절차를 준수함으로써 엔지니어는 중요한 응용 분야에서 밀봉 밀봉의 신뢰성과 효율성을 보장할 수 있습니다.

One of the most notable physical properties of 인듐 is its exceptional ductility and malleability. Indium possesses a Mohs hardness of just 1.2, significantly lower than that of copper (2.5-3) and aluminum (2-2.9), making it much softer and easier to deform.

It has a relatively low melting point of 156.6°C, allowing it to be easily molded into various shapes and sizes, such as preforms and wires, to fit specific sealing applications.

Indium can be fabricated into thicknesses ranging from thin (0.008 inches) to thick (0.062 inches), depending on the mating surfaces and required compressive forces.

Indium‘s ability to form hermetic seals without the need for heat is particularly advantageous in environments where heat or solder flux might cause issues such as outgassing.

When used as a sealant, indium initiates a chemical bond with the surfaces it connects, offering superior sealing capabilities compared to other gasket materials which merely act as barriers.

This property allows indium seals to maintain their integrity even under mechanical shock, vibration, and extreme temperatures, making them indispensable in demanding applications.

Proper surface preparation is critical for achieving high-quality indium seals. Surfaces must be thoroughly cleaned and dried, with specific treatments for different materials. For example, glass and ceramic surfaces should be treated with chromic and sulfuric acids, followed by a hydrochloric acid and deionized water rinse.

Indium metal surfaces may require pre-tinning or plating with indium or silver to ensure optimal bonding.

The removal of surface oxides through compression and plastic deformation is facilitated by the malleability of indium, ensuring effective sealing even at cryogenic temperatures.

Indium’s versatility extends to its use in forming helium-tight hermetic seals, capable of bridging metals and non-metallic substrates like glass and ceramics. This makes indium an essential material in applications requiring reliable performance in vacuum pumps, cryogenic environments, and other heat-sensitive areas.

Indium vacuum sealing technology leverages the unique properties of indium to create reliable and effective seals in a variety of applications, including cryogenic environments, vacuum pumps, and heat-sensitive areas.

This technology is particularly valued for its ability to form helium-tight hermetic seals, bridging both metallic and non-metallic substrates like glass and ceramics.

Properties and Advantages

Indium is characterized by its low melting point, high malleability, and ductility, which make it an ideal material for vacuum sealing.

Unlike gaskets made from other materials that only form a barrier, indium creates a chemical bond with the surfaces it connects, enhancing the seal’s resilience against mechanical shock, vibration, and low temperatures.

A notable feature of indium is its tendency to develop an oxide film on its surface. To establish a pristine bond with a substrate, this oxide film must be disrupted through compression and plastic deformation, a process facilitated by the metal’s malleability.

This ensures effective sealing even at cryogenic temperatures without the need for heat.
