    • Disclosed herein is a method for surface treatment which comprises subjecting an object for surface treatment to an atmospheric pressure plasma while rolling or floating said object in an insulating vessel fed with a prescribed gas and provided on the outside thereof or on both the outside and inside thereof with electrodes for voltage application and grounding, said atmospheric pressure plasma occurring upon application of a voltage to said electrodes. This method permits simple, certain, and uniform surface treatment of any objects in the form of lump or sphere. The surface treatment by the atmospheric pressure plasma does not need the apparatus to be evacuated. Therefore, it can be carried out in a simple apparatus without causing the object for surface treatment to release volatile matters.Disclosed also herein is a method for the surface treatment of vulcanized rubber with an atmospheric pressure plasma in the presence of an oxygen-containing gas and halogen containing gases. This method is simple and permits the surface treatment of vulcanized rubber in a clean environment. The surface treatment by this method provides the vulcanized rubber with a surface having better adhesion properties than the surface treatment with a low-pressure glow plasma. Moreover, the surface treatment is limited only to a very thin surface layer, with the vulcanized rubber itself remaining intact.
    • 本发明公开了一种表面处理方法,其特征在于,在进行了规定气体的绝缘容器的滚动或浮动的同时将其进行表面处理的物体进行表面处理,并且设置在其外侧或其外部和内部 具有用于施加电压和接地的电极,所述大气压等离子体在对所述电极施加电压时发生。 这种方法允许以块状​​或球形的形式对任何物体进行简单,确定和均匀的表面处理。 通过大气压等离子体的表面处理不需要抽真空的装置。 因此,可以在简单的装置中进行,而不会导致表面处理物体释放挥发性物质。 本文还公开了在含氧气体和含卤素气体的存在下用大气压等离子体表面处理硫化橡胶的方法。 该方法简单,可在干净的环境中对硫化橡胶进行表面处理。 通过该方法进行的表面处理为硫化橡胶提供了具有比用低压辉光等离子体进行的表面处理更好的粘合性能的表面。 此外,表面处理仅限于非常薄的表面层,硫化橡胶本身保持完整。
