Composite vacuum panel with sealing strips and getter and manufacturing method thereof
A composite vacuum panel with sealing strips and a getter comprises a surface plate, a core plate and a vacuum chamber and is characterized in that the surface plate is welded or adhered to the outer upper surface of the vacuum chamber to be fixed to the outer upper surface of the vacuum chamber, the core plate is arranged at the inner bottom of the vacuum chamber, the surface plate and/or the core plate provide the vacuum chamber with additional strength to ensure the smoothness of the vacuum chamber at atmospheric pressure, the vacuum chamber is a closed chamber formed by a low-carbon steel plate subjected to glass soldering edge sealing at atmospheric pressure and high temperature and high-temperature opening sealing in vacuum, welding portions of the edge of the low-carbon steel plate are provided with the sealing strips, the opening sealing is the automatic sealing of pumping holes preformed in the vacuum chamber with low-temperature solder in a vacuum furnace according to the principle of liquid seal, and supporting members and the getter are arranged in the vacuum chamber. A manufacturing method of the composite vacuum panel with the sealing strips and the getter is simple in process. The manufactured composite vacuum panel with the getter can overcome the deficiencies of existing insulation boards and vacuum insulation panels and the strength, thermal insulation, sound insulation and fireproof performance and decorative functions can be improved.
