Double-vacuum-layer metal vacuum composite plate with edge sealed by seal strip and manufacturing method thereof
A double-vacuum-layer metal vacuum composite plate with the edge sealed by a seal strip comprises a housing, at least two core plates and a vacuum cavity and is characterized in that the housing is a low-carbon steel plate or a low-carbon steel composite plate, the core plates are located in the vacuum cavity formed through seal welding of the housing, the core plates provide additional strength for the housing and ensure the smoothness of the housing under atmospheric pressure, the vacuum cavity is welded and sealed by utilizing a glass solder in a vacuum furnace under high vacuum and high temperature, the seal strip is arranged at the welding position of the edge portion of the low-carbon steel plate, the coefficient of thermal expansion of the low-carbon steel plate is matched with that of the glass solder, a partition plate is arranged in the vacuum cavity and divides the vacuum cavity into two to form double vacuum layers, and supports are arranged in the vacuum layers and are independently manufactured or are directly formed on the core plate or the partition plate. A manufacturing method of the double-vacuum-layer metal vacuum composite plate is simple in process, and strength, heat-insulation, sound-insulation and fireproof performance and a decorative function can be improved.
