Technical field
The present invention relates to ceramic field, specifically, is related to a kind of preparation process based on the internal wall brick once burnt.
Background technology
In existing ceramic tile preparation process, it can be divided into and once fire and secondary burning process.
The technique once fired causes glaze paint quality and base substrate quality to be difficult to control since base substrate denitrogen exhaust effect is poor.
As an improvement, using secondary burning process mostly in the industry, glaze paint quality is ensured by secondary burning process.But It is secondary fire there are the problem of be also what be can not be ignored, specifically, high energy consumption, efficiency are low, size after secondary firing not It is easy to control, relatively low dimension precision requirement carries out edging to product.
The content of the invention
The object of the present invention is to provide a kind of preparation process based on the internal wall brick once burnt, which is prepared interior Wall brick size distortion rate is low, glaze paint constant quality influences from base substrate.
Technical solution provided by the invention is：A kind of preparation process based on the internal wall brick once burnt, the internal wall brick By being obtained by raw material ball milling, pressed compact, drying, cloth glaze and once after firing；
