Abstract

The invention relates to a ceramic inkjet glazing production method which comprises the following steps of: mixing clay, feldspar and water to form pug in percent by mass; feeding the pug into an extruder, setting a pressure range of the extruder to be 22-32 MPa; drying in a five-layer drying kiln, setting the temperature to be 150-250 DEG C, and controlling the moisture of the green body to be 3 percent below; keeping the temperature of the green body to be 45-65 DEG C after drying, and performing ground coat and overglaze spraying; keeping the temperature of the green body to be 45-65 DEG C after the ground coat and overglaze spraying is finished, and automatically jetting ink in an inkjet machine; spraying a protective glaze layer after inkjet is finished; and finally, firing in a kiln, and performing trimming processing according to the size specification after firing is finished. The method has the beneficial effects that the method is easy to operate and convenient for mass production, the color of the ceramic plate is increased, the application range of the ceramic plate is widened, the yield of the ceramic plate is improved, and the practicality is improved.

Description

Technical field [0001] The invention relates to the field of architectural ceramics, in particular to a production method for inkjet glaze application of ceramic plates. Background technique [0002] Ceramic board is a high-grade exterior wall decoration material developed in recent years. Due to its unique internal cavity structure, it has the performance of thermal insulation and noise reduction. It is processed by dozens of processes such as trimming after the mud is processed by the vacuum extruder and then enters the drying kiln for drying, passes through the glaze line and enters the kiln for firing. The production method of ceramic slabs is complicated and inconvenient to operate. Most of them have a single surface design and are only used for exterior wall decoration. Moreover, the yield rate is relatively low, the use time is short, and it is not practical. Summary of the invention [0003] The purpose of the present invention is to provide an inkjet glaze production met...
