Abstract
A production method and applications of a transition layer composite foam ceramic plate are provided. The method includes steps of inverting a formed green body into a mold cavity of a refractory mold, with the thickness of the green body being smaller than the depth of the mold cavity; applying transition powder to the mold cavity of the refractory mold to form a transition powder layer on the bottom surface of the green body; and then applying well known foaming powder containing a high-temperature sintering expanding and foaming material to the mold cavity of the refractory mold to form a foaming powder layer on the transition powder layer. The production method for the transition layer composite foam ceramic plate is provided and avoids green body deformation caused by lateral foaming and expanding of powder materials of a composite layer at the two lateral directions of the green body, thus overcoming a technical problem in the prior art that deformation in preparation of composite foam ceramic bricks is liable to occur. In addition, the applications of the composite foam ceramic plate prepared by the production method are also provided. Loads of exterior walls of buildings can be greatly reduced and the heat insulation and fireproof properties can be improved.
Description
technical field [0001] The invention relates to the technical field of ceramic tiles, in particular to a production method of a transition layer composite foam ceramic plate. Background technique [0002] In the existing external wall installation, the installation method generally uses keels for dry hanging. On the one hand, because ceramic tiles are heavy, if tile adhesive is used for glueing, the glue force is limited, and it cannot be glued for large areas or heavy weights. Ceramic tiles, on the other hand, the alumina on the sticks in the production process remains on the bottom of the ceramic tiles, which will affect the connection between the tile adhesive and the brick surface, resulting in the ceramic tiles not being firmly glued to the outer wall. Therefore, when using the tile adhesive installation method Only ceramic tiles with small area and light weight can be used. [0003] For the external wall installed with keel dry hanging, after dry hanging, there is a c...
