Glass welded composite vacuum plate and production method thereof
The invention discloses a glass welded composite vacuum plate. The vacuum plate comprises a panel, core veneers and a vacuum cavity, and is characterized in that the panel is fixed on the upper surface outside the vacuum cavity through either a welding or a gluing way, the core veneers are placed at the inner bottom of the vacuum cavity, the vacuum cavity is formed by welding low-carbon steel plates and 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 hermetically sealed by a glass solder in a vacuum furnace at high vacuum and high temperature; the coefficients of thermal expansion of low carbon steel plates and the glass solder are matched, and a support is arranged in the vacuum cavity and is separately made or directly formed in the inner wall of the vacuum cavity. A production method of the glass welded composite vacuum plate provided by the invention is simple in process, the air-tightness of the vacuum cavity of the glass composite vacuum plate can be effectively ensured, the service life of the glass composite vacuum plate can be prolonged, and the strength, heat insulation, sound insulation, fire resistance and decorative function can be enhanced.
