Bake-out, in several areas of technology and fabrication, and in building construction, refers to the process of using high heat temperature (heat), and possibly vacuum, to remove volatile compounds from materials and objects before placing them into situations where the slow release of the same volatile compounds would contaminate the contents of a container or vessel, spoil a vacuum, or cause discomfort (odor or irritation) or illness. Bake-out is an artificial acceleration of the process of outgassing.

  • 在一些技术、制造领域及建筑施工领域中，烘干，指的是利用高温（热），或是使用真空，提前将材料和物体中的挥发性化合物除去，以免这些化合物的缓慢挥发在容器或压力容器中产生污染，破坏真空，甚至引起不适或疾病。烘干是对释气过程的人为加速。 在浸入之前通常都要在非真空环境中干燥，因为即使少量的水也会削弱绝缘油的绝缘性能。 在各种物理学和真空器件工程，如粒子加速器、半导体制造和真空管中，烘干是一种制造过程，即将部件置于真空室中（或其真空运转状态，用于在真空中工作的器件）通过内置加热器加热。这样可以通过不断运作的真空泵排出气体。 在建筑施工中，烘干是利用热量去除建筑物施工后的挥发性有机化合物，例如在油漆，地面和其它建筑材料中残留的溶剂，以减少异味或改善室内空气质量。建筑物内部通常会被加热到较高的温度，并保持较长时间，以使这些化合物蒸发到空气中并排出（释放到大气中）。 (zh)

Kristallgitter-Fehlstellen) aus Materialien oder Apparaten durch kontrolliertes Erhitzen auf eine bestimmte Temperatur über definierte Zeitspannen hinweg. (de)

  • Ausheizen bezeichnet das Entfernen unerwünschter und zum Teil auch schädlicher Einflüsse, wie adsorbierte Stoffe an Oberflächen (z. B. Wasser), Verunreinigungen oder Konstellationen (z. B. Kristallgitter-Fehlstellen) aus Materialien oder Apparaten durch kontrolliertes Erhitzen auf eine bestimmte Temperatur über definierte Zeitspannen hinweg. Damit die entfernten Stoffe die zu reinigenden Materialien nicht sofort wieder verschmutzen, sind teilweise zusätzliche Maßnahmen notwendig. So werden beispielsweise desorbierte Restgase mithilfe von Vakuumpumpen abgesaugt, d. h., die Proben werden unter Vakuum ausgeheizt. (de)
  • Bake-out, in several areas of technology and fabrication, and in building construction, refers to the process of using high heat temperature (heat), and possibly vacuum, to remove volatile compounds from materials and objects before placing them into situations where the slow release of the same volatile compounds would contaminate the contents of a container or vessel, spoil a vacuum, or cause discomfort (odor or irritation) or illness. Bake-out is an artificial acceleration of the process of outgassing. Electrical insulation paper is often baked dry, without vacuum, before being placed into insulating oil, because even small amounts of water degrade the insulating performance of oil. In various physics and vacuum device engineering, such as particle accelerators, semiconductor fabrication, and vacuum tubes, bake-out is a manufacturing process, the period of time when a part or device is placed in a vacuum chamber (or its operating vacuum state, for devices which operate in a vacuum) and heated, usually by built-in heaters. This drives off gases, which are removed by continued operation of the vacuum pump. In building construction, bake-out is the use of heat to remove volatile organic compounds such as solvents remaining in paint, carpets, and other building materials from a building after its construction, to reduce annoying odors or improve indoor air quality. The building interior is heated to a much higher temperature than normal and kept at that temperature for an extended period of time, to encourage such compounds to vaporize into the air, which is vented (released to the atmosphere).
