Glass welded double-vacuum-layer metal vacuum composite plate with getter and production method thereof
The invention discloses a glass welded double-vacuum-layer metal vacuum composite plate with a getter. The double-vacuum-layer metal vacuum composite plate comprises a panel, core veneers and a vacuum cavity, and is characterized in that the shell is made from either a low carbon steel plate or a low carbon steel composite plate, the core veneers are placed in the inner bottom of the vacuum cavity and are used for providing additional strength to the shell to ensure the smoothness of the shell at barometric pressure, the vacuum cavity is a closed cavity formed by carrying out glass welding at constant temperature and high temperature and sealing at constant pressure to the shell; 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 metal vacuum composite 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.
