Ceramic glaze screening process

Abstract

The invention provides a ceramic glaze screening process, which takes 35 parts of quartz, 25 parts of feldspar, 30 parts of sandstone, 17 parts of talc, 13 parts of knar clay and 6 parts of dry alkali as raw materials, and comprises a series of process steps of raw material pretreatment, sub-packaging, mixing, secondary mixing, tertiary mixing, screening and the like. The ceramic glaze is further screened. The screening process comprises the following steps: respectively grinding quartz, feldspar, sandstone, talc, knar clay and dry alkali by using a grinding disc, screening twice by using a filter sieve with a 180-mesh sieve, adding 17 parts of clear water into the treated quartz and feldspar, uniformly mixing, adding sandstone in the mixing process, mixing for 18 minutes, gradually adding talc, knar clay and dry alkali into the mixture of mixed quartz, feldspar and sandstone, adding 18 parts of clear water, mixing for 26 minutes, and pouring the mixed glaze liquid into a glaze liquid filter sieve.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular, the invention relates to the technical field of a screening process of a ceramic glaze screening process. [0002] technical background [0003] Ceramic glaze is a glassy thin layer attached to the surface of the ceramic body. It is made by mixing mineral raw materials and chemical raw materials in a certain proportion and finely grinding them into a slurry liquid, which is applied to the surface of the body and calcined at high temperature; [0004] With the development of the construction industry, the market demand for ceramics is increasing, and its quality requirements are also getting higher and higher. In the production process of ceramic products, ceramic glazes need to be screened to remove impurities inside ceramic glazes. ; [0005] There are many sieving methods for ceramic glazes in the prior art.

AI Technical Summary

Problems solved by technology

[0005] There are many sieving methods for ceramic glazes in the prior art. The commonly used method is grinding and modulation. This method usually grinds ceramic glaze raw materials and then adds water to prepare ceramic glazes. Because ceramic glazes need to use a variety of raw materials for mixing and grinding , and the internal particle size of the raw material is different after grinding. The traditional process usually filters and sieves the prepared ceramic glaze, which leads to the existence of certain impurity particles in the ceramic glaze after preparation, and the viscous texture of the ceramic glaze liquid, which is prone to sieves after filtering. The situation of incomplete separation will cause air bubbles to appear easily when the ceramic surface is subsequently coated, and uneven color will appear after heating. The application provides a ceramic glaze screening process, thereby overcoming the deficiencies in the prior art, and The above problems can be solved by sieving the ceramic glaze raw materials in stages to reduce the bubbles inside the ceramic glaze, and the color and smoothness can be improved.
