Glass welded metal vacuum composite plate with getter and production method thereof
The invention discloses a glass welded metal vacuum composite plate with a getter. The metal vacuum composite plate comprises a shell, core veneers and a vacuum cavity, and is characterized in the shell is made from either a low carbon steel plate or a low carbon steel composite plate, the core veneers are located in the vacuum cavity and are used for providing additional strength to the shell to ensure the smoothness of the shell at barometric pressure, and 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 and the coefficients of thermal expansion of the low carbon steel plate and the glass solder are matched; 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 getter is arranged in the vacuum cavity, the number of the core veneers is at least two and a support is arranged between the core veneers. A production method of the metal vacuum composite plate with the getter 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.
