Glass welded double-vacuum-layer composite vacuum plate and production method thereof
The invention discloses a glass welded double-vacuum-layer composite vacuum plate. 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 at the upper outside surface of the vacuum cavity by either a welding way or a gluing way, the core veneers are placed at the inner bottom of the vacuum cavity, and the vacuum cavity is formed by welding a thin low carbon steel plate; the panel and/or the core veneers are used for providing additional strength to the vacuum cavity, and the vacuum cavity is hermetically welded by a glass solder at high vacuum and high temperature in a vacuum furnace, the coefficients of thermal expansion of the low carbon steel plate and the glass solder are matched, a clapboard is arranged in the vacuum cavity and is used for dividing the vacuum cavity into double vacuum layers, and supports are arranged in the vacuum layers and are separately made or directly formed on the vacuum cavity or the clapboard. A production method of the double-vacuum-layer composite vacuum plate provided by the invention is simple in process, and the strength, heat insulation, sound insulation, fire resistance and decorative function can be improved.
