Composite vacuum panel with sealing strips and mounting holes and manufacturing method thereof
A composite vacuum panel with sealing strips and mounting holes comprises a surface plate, a core plate and a vacuum chamber and is characterized in that the mounting holes are combined with pumping holes and penetrate through the whole composite plate, the surface plate is welded or adhered to the upper surface of the vacuum chamber to be fixed to the 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/provides the vacuum chamber with additional strength, 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 the 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 are arranged in the vacuum chamber. A manufacturing method of the composite vacuum panel with the sealing strips and the mounting holes is simple in process. The manufactured composite vacuum panel with the mounting holes can overcome the deficiencies of existing insulation boards and vacuum insulation panels and the strength and thermal insulation, sound insulation and fireproof performance can be improved.
