A kind of manufacturing method of high-temperature bulk relief porcelain plate

Abstract

The invention provides a method for manufacturing a high-temperature large relief porcelain plate, which comprises the following steps: making relief mud and glaze; creating relief works; making working seed molds; forming a glaze layer on the relief surface of the relief mud; demolding ;Perfect engraving and decoration; Bisque firing treatment of large relief porcelain plates; Grinding and modification of large relief porcelain plates after bisque firing; High-temperature firing treatment of large relief porcelain plates; The porcelain plate is polished to obtain the pre-finished product; the pre-finished product is refired for the third time; the pre-finished product is cooled to the outdoor temperature and then out of the kiln, and then polished and quality inspected to obtain the finished product; a single finished product or multiple The assembled finished products are framed and packaged. The invention has a high qualified rate of finished products and has the advantages of large size specifications of 1.4-1.8m in length, 0.8-1.2m in width, and 1.7-3cm in thickness, and can ensure flatness requirements during assembly operations.

Description

technical field [0001] The invention relates to the technical field of porcelain plate production, in particular to a method for producing high-temperature large embossed porcelain plates. Background technique [0002] At present, in the white porcelain industry, embossing patterns on the surface of art porcelain products and carrying out pattern decoration is a common and effective method to increase product texture and aesthetic feeling. Most of the embossed patterns are embossed by hand. However, the manual relief has the following defects: the relief lines are not smooth, stiff and rigid, the relief area is small, and the creation cost is high. In addition, the small relief area restricts the size and specifications of the porcelain plate products. If you want to assemble multiple porcelain plate products into a large-screen artwork, you need to use smaller porcelain plate products, which increases the difficulty of assembling flat . [0003] The invention patent with ...

AI Technical Summary

Problems solved by technology

However, manual relief has the following defects: the relief lines are not smooth, stiff and rigid, the relief area is small, and the creation cost is high.

The embossed product prepared by this patent does not have the advantage of large size, cannot guarantee the flatness requirement during assembly operation, and the processing conditions cannot control the shrinkage rate of the embossed product, and thus cannot guarantee the qualified rate of the embossed product

[0004] In summary, there is an urgent need for a method for manufacturing high-temperature large relief porcelain plates to solve the problems of low pass rate and small size in the prior art
