Metal vacuum heat-insulation plate with edge sealed by seal strip and manufacturing method thereof
A metal vacuum heat-insulation plate with edge sealed by a seal strip comprises a housing, a core material 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 material is located in the vacuum cavity formed through sealing and welding of the housing, the core material provides additional strength for the housing and ensures 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, and the low-carbon steel plate is matched with the coefficient of thermal expansion of the glass solder. A manufacturing method of the metal vacuum heat-insulation plate with the edge sealed by the seal strip is simple in process, the manufactured metal vacuum composite heat-insulation plate can overcome the shortcomings of existing heat preservation plates and vacuum heat-insulation plates, the air impermeability of the vacuum cavity of the metal vacuum heat-insulation plate can be effectively ensured, the service life of the metal vacuum heat-insulation plate can be prolonged, and strength, heat-insulation, sound-insulation and fireproof performance and a decorative function can be improved.
