Ceramic composite vacuum panel with sealing strips and getter and manufacturing method thereof
A 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 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 and the getter are arranged in the vacuum chamber. A manufacturing method of the ceramic composite vacuum panel with the sealing strips and the getter is simple in process. The ceramic composite vacuum panel with the getter can effectively ensure the gas tightness of the vacuum chamber, the service life can be prolonged, and the strength and thermal insulation, sound insulation and fireproof performance can be improved.
