Abstract

The invention relates to the field of ceramics, in particular to a slip casting preparation method for high-whiteness earthenware. The method comprises the following steps: selecting mineral raw minerals, namely selecting the following ceramic mineral sources with high purity in parts: 38 to 42 parts of Suzhou kaolin clay, 26 to 30 parts of Pingjiang feldspar, 24 to 33 parts of Jiangxi porcelain stone and 3 to 5 parts of Haicheng talc, performing washing and preparation, treating mud after ball milling by virtue of an additional pressure filtration procedure, performing slip casting to obtain a blank and firing the blank. According to the method, a process flow of sequentially performing high-temperature biscuit firing and low-temperature glaze firing is adopted, the apparent quality of a burnt matrix is similar to that of ceramic whiteware, the section is substantially sintered to be compacted, the whiteness reaches 70 percent, and the water absorption is lower than 0.5 percent; the product has practical value, and is as white and pleasant as cream.

Description

technical field

[0001] The invention relates to the field of ceramics, in particular to a method for preparing pottery with high whiteness through grouting. Background technique

[0002] At present, the texture of daily-use pottery is generally poor in whiteness, which seriously affects the aesthetics of the product. This is caused by the natural raw materials that are directly used by ceramic companies without strict processing. Therefore, for judging the quality of daily-use ceramics, the whiteness of appearance is an important indicator, and it is imperative to innovate the processing technology of pottery blanks. Contents of the invention

[0003] In order to solve the above problems, the present invention provides a method for preparing pottery products with high whiteness.

[0004] A preparation method for grouting molding high whiteness pottery, comprising the following steps:

[0005] The billets are selected and washed first, and the billets are proportioned acc...
