Double-vacuum-layer glass composite vacuum heat-insulation plate with edge sealed by seal strip and manufacturing method thereof
A double-vacuum-layer glass composite vacuum heat-insulation 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 glass plate, the vacuum cavity is a closed cavity formed by welding a low-carbon steel plate and sealing the edge by utilizing a glass solder under the constant pressure and high temperature and performing high-temperature sealing under the vacuum condition, the seal strip is arranged at the welding position of the edge portion of the low-carbon steel plate, the sealing is automatic sealing performed by utilizing an air exhaust opening pre-formed in the vacuum cavity and a low-temperature solder in a vacuum furnace according to a liquid seal principle, the low-temperature solder includes low-temperature metal and an alloy 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. A manufacturing method of the double-vacuum-layer glass composite vacuum heat-insulation plate is simple in process, the manufactured double-vacuum-layer glass composite vacuum heat-insulation plate can overcome the shortcomings of existing heat preservation plates and vacuum heat-insulation plates, and strength and heat-insulation, sound-insulation and fireproof performance can be improved.
