Abstract

The invention discloses a graphene ceramic tile burning method. The burning method comprises the following steps: compounding 35 parts of potassium feldspar, wollastonite, spodumene, alundum powder, attapulgite, diatomite, yellow phosphorite slag and the like to obtain a raw material of graphene ceramic tiles; controlling the moisture of silica sol to obtain a wet blank and a dry blank in sequence; finally, sintering. During sintering, condensation occurs among silanol groups on the surfaces of colloidal particles in order to drive the components of the graphene ceramic tiles to get close andgather, gaps among the components are filled with the colloidal particles, and the colloidal particles are bonded through chemical bonds (Si-O-Si) to form a stable space network structure, so that thecomponents are firmly combined together, the pore forming probability is lowered greatly, the porosity is lowered remarkably, and graphene ceramic tiles with low water absorption can be obtained.

Description

technical field [0001] The invention belongs to the technical field of building ceramic materials, and in particular relates to a method for firing graphene tiles. Background technique [0002] Ceramic bricks are plate or block ceramic products produced by clay, quartz sand and other inorganic non-metallic raw materials through batching, ball milling, powder making, molding, sintering and other processes. They are widely used in decoration and protection of walls of buildings and structures. and ground. Ceramic tiles are a type of ceramic tiles that have a water absorption rate of less than 0.5%. The ceramic body becomes a dense sintered body after high-temperature calcination, and there are many small pores on the sintered body. It is these small pores that make the ceramic tile have a certain water absorption rate. The water absorption rate directly affects the paste and use performance of the tiles, and is also an important indicator for evaluating the quality of the ti...
