Double-vacuum-layer ceramic composite vacuum panel with sealing strips and getter and manufacturing method thereof
A double-vacuum-layer ceramic composite vacuum panel with sealing strips and a getter comprises a surface plate, a connecting layer and a vacuum chamber and is characterized in that 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 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, a separation plate separating the vacuum chamber into two to form double vacuum layers is arranged in the vacuum chamber, and supporting members are arranged in the vacuum layers. A manufacturing method of the double-vacuum-layer ceramic composite vacuum panel with the sealing strips and the getter is simple in process. The manufactured double-vacuum-layer ceramic composite vacuum panel with the getter 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.
