Ceramic composite vacuum panel with sealing strips and mounting holes and manufacturing method thereof
A ceramic composite vacuum panel with sealing strips and mounting holes comprises a surface plate, a connecting layer 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 a ceramic plate or tile, the surface plate and/or the connecting layer provide/provides 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 coefficient of thermal expansion of the low-carbon steel plate is matched with that of glass solder, 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 ceramic composite vacuum panel with the sealing strips and the mounting holes is simple in process. The strength and thermal insulation, sound insulation and fireproof performance of the ceramic composite vacuum panel with the mounting holes can be improved.
