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

Embodiment 1

[0045] A method for manufacturing a large high-temperature embossed porcelain plate, comprising the following steps:

[0046] The first step, making relief mud and glaze, specifically: the relief mud consists of 30-40% of large ball clay, 20%-25% of kaolin, 5%-20% of potassium feldspar, quartz 5%-20% and 10%-25% of porcelain powder are made of mud; the glaze includes 42%-60% of feldspar, 10%-15% of talc, 20%-30% of quartz and Clay 5%-8%;

[0047] The second step is to create relief works and turn them into relief plaster molds or relief silicone molds;

[0048] The 3rd step, make relief gypsum mold or relief silica gel mold into the working model of relief works, described working model comprises upper mold and lower mold;

[0049] Step 4: Put the relief mud in the working mold and adjust the gap between the upper mold and the lower mold to 3cm, and use the grouting equipment to inject high pressure into the gap along four different directions of the working mold Glaze, for...

Abstract

The invention provides a manufacturing method of a high-temperature large embossed porcelain plate. The manufacturing method comprises the following steps: manufacturing an embossment mud blank and aglaze; creating embossment works; manufacturing a working seed mold; forming a glaze layer on the embossment surface of the embossment mud blank; demolding; carrying out perfect engraving decoration;biscuiting the large embossment porcelain plate; polishing and modifying the biscuit-fired large embossment porcelain plate; carrying out high-temperature firing treatment on the large embossment porcelain plate; polishing the large embossment porcelain plate subjected to high-temperature firing to obtain a prefabricated product; carrying out third re-firing treatment on the prefabricated product;cooling the prefabricated product to the outdoor temperature, taking out of the kiln, and carrying out polishing and quality inspection treatment again to obtain a finished product; and carrying outframe packaging treatment on a single finished product or a plurality of assembled finished products. According to the invention, the finished product is high in qualification rate, has the large-sizespecification advantages of the length of 1.4-1.8 m, the width of 0.8-1.2 m and the thickness of 1.7-3 cm, and can ensure the flatness requirement during splicing operation.

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 plate. 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 t...
