Composite vacuum plate with edge sealed by seal strip and manufacturing method thereof
A composite vacuum plate with the edge sealed by a seal strip comprises a face plate, a core plate and a vacuum cavity and is characterized in that the face plate is fixed to the upper surface outside the vacuum cavity in a welding or bonding mode, the core plate is arranged at the bottom of the inside of the vacuum cavity, the vacuum cavity is formed by welding a low-carbon steel plate, the face plate and/or the core plate provide/provides additional strength for the vacuum cavity, the vacuum cavity is welded and sealed by utilizing a glass solder in a vacuum furnace under the 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, and a support is arranged in the vacuum cavity and is independently manufactured or is directly formed on the inner wall of the vacuum cavity or the core plate. A manufacturing method of the composite vacuum plate is simple in process, the air impermeability of the vacuum cavity of the composite vacuum plate can be effectively ensured, the service life of the composite vacuum plate can be prolonged, and strength, heat-insulation, sound-insulation and fireproof performance and a decorative function can be improved.
