Problems solved by technology

Ceramic products have their own objective laws in the production process, which can be applied within a certain range to achieve the desired effect, and can also change some of the links to achieve the desired effect. However, the most common in the traditional ceramic industry Problem - cracking and deformation, the fundamental reason is the shrinkage during the drying and firing process. Although it can be solved by optimizing the shape design, adjusting the formula, and revising the technical indicators of the process, this adjustment is limited, because It is almost impossible to prevent ceramics from shrinking during the drying and firing process, especially for cubic or larger flat products, the cracking and deformation are particularly prominent, often the yield is very low and the cost is high; at the same time, traditional ceramic production must be fired , not only consume a lot of energy, but also cause environmental pollution

Abstract

The invention discloses a production method for a non-plastic unburned ceramic product. The ceramic product is produced by adding a liquid raw material composed of magnesium chloride, sodium silicate and defoamer in poor raw materials of industrial magnesium oxide, quartz, silicon carbide and chamotte powder, and injecting in a non-water-absorbent material die by a solid grouting method. The method disclosed by the invention is capable of producing cubic ceramic products and large product ceramic arts, has the advantages of being simplified in procedures, simple and easy to learn, energy-saving and environment-friendly, low in cost, wide in application range and the like, and is capable of providing more better choices for consumers, and good in social benefits and economic benefits.

Description

technical field [0001] The invention relates to a method for making pottery products, in particular to a method for making non-plastic non-fired pottery products. Background technique [0002] The ceramic industry is an important part of the silicic acid industry, and ceramics is a general term for clay products such as pottery, stoneware and porcelain. Pottery production has a long history in our country. The ceramic craft in the traditional sense consists of four basic parts: raw material processing, molding, firing, and decoration. The raw materials used include plastic raw materials, non-plastic raw materials (barren raw materials), and flux raw materials. Ceramic products have their own objective laws in the production process, which can be applied within a certain range to achieve the desired effect, and can also change some of the links to achieve the desired effect. However, the most common in the traditional ceramic industry Problem - cracking and deformation, the ...
