Glass welded double-vacuum-layer composite vacuum plate with getter and production method thereof
The invention discloses a glass welded double-vacuum-layer composite vacuum plate with a getter. The double-vacuum-layer composite vacuum plate comprises a panel, core veneers and a vacuum cavity, and is characterized in that the panel is fixed on the upper outer surface of the vacuum cavity, the core veneers are placed in the inner bottom of the vacuum cavity, the panel and/or the core veneers are used for providing additional strength to the vacuum cavity to ensure the smoothness of the vacuum cavity at barometric pressure, the vacuum cavity is a closed cavity formed by carrying out glass welding at normal pressure and high temperature and sealing at high temperature to a low carbon steel plate; the sealing is that an extraction opening preformed in the vacuum cavity is automatically sealed by a low temperature solder in a vacuum furnace according to a liquid sealing theory, and a clapboard is arranged in the vacuum cavity and is used for dividing the vacuum cavity into double vacuum layers in which supports are arranged. A production method of the double-vacuum-layer composite vacuum plate provided by the invention is simple in process, the defects of an existing insulation board and an existing vacuum insulated panel can be overcome, and the strength, heat insulation, sound insulation and fire resistance can be improved.
