Double-vacuum-layer ceramic composite vacuum plate with edge sealed by seal strip and manufacturing method thereof
A double-vacuum-layer ceramic composite vacuum plate with the edge sealed by a seal strip comprises a face plate, a connecting layer and a vacuum cavity and is characterized in that the face plate is a ceramic plate or is made of ceramic tiles, the connection layer enables the face plate and the vacuum cavity to be connected to form a whole, the vacuum cavity is formed by welding a thin low carbon metal plate and is welded and sealed by utilizing a glass solder in a vacuum furnace under the high vacuum and high temperature, the seal strip is arranged at the welding position of the edge portion of the low-carbon steel plate, the coefficient of thermal expansion of the low-carbon steel plate is matched with that of the glass solder, a partition plate is arranged in the vacuum cavity and divides the vacuum cavity into two to form double vacuum layers, and supports are arranged in the vacuum layers and are independently manufactured or are directly formed on the vacuum cavity or the partition plate. A manufacturing method of the double-vacuum-layer ceramic composite vacuum plate is simple in process, and strength and heat-insulation, sound-insulation and fireproof performance can be improved.
