Embodiment Construction

[0013] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and clearer, the present invention will be further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0014] The invention provides a kind of mud for high-pressure grouting molding. Its preparation method is to prepare mud first, and the components of the mud include water-washed china clay 15.3-20%, Guangdong black mud 5.2-5.6%, and kaolin 20-23% by weight. %, porcelain stone 27-29%, calcined kaolin 6-10%, feldspar 16-19%, dolomite 2-2.5%. Among them, the nature of water-washed china clay is illite-type clay, which has good plasticity and improves the cracking time of mud. The place of production is Jiefu, Yongchun, Fujian, and you can choose Fujian Kefu Material Co., Ltd. Ka...

Abstract

The invention discloses a high-pressure slip casting slurry comprising the components by the weight percentage: 73-74.7% of a mud material, 24.8-26.5% of water, 0.08-0.15% of dietary alkali, and 0.41-0.45% of water glass; the mud material comprises the components by the weight percentage: 15.3-20% of water washed china clay, 5.2-5.6% of Guangdong black mud, 20-23% of kaolin, 27-29% of porcelain stone, 6-10% of calcined kaolin, 16-19% of feldspar, and 2-2.5% of dolomite. With use of the formula, on one hand, the slurry casting speed of the slurry in the high-pressure grouting process can be improved, the physical strength of a blank prepared by the slurry can be ensured, and the carrying damage rate of the blank is reduced; and on the other hand, the fluidity of the slurry can be improved, the slurry filling time and the slurry discharge time are reduced, and the occurrence rate of corner dry cracking in the drying process is guaranteed to be controlled at a relatively low level.

Description

technical field [0001] The invention relates to the field of ceramic manufacturing, in particular to mud for slip casting. Background technique [0002] With the development of the sanitary ceramics industry, in the production process of ceramics, the high-pressure grouting molding process accounts for an increasing proportion in the industry. Compared with low-pressure molding, high-pressure molding has the characteristics of high efficiency and low labor intensity. However, the slurry material used for gypsum mold grouting can no longer meet the needs of high-pressure molding. Therefore, it is particularly important to prepare slurry suitable for high-pressure grouting. Among them, the slurry eating speed and the fluidity of the slurry determine the molding cycle and production efficiency of high pressure molding. Therefore, the preparation of slurry with higher slurry-eating speed and better fluidity has become an urgent demand for high-pressure forming technology to pro...
