Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a grouting process, which has the advantages of improving the density of the blank, reducing the generation of internal pores and air bubbles, greatly improving the quality of the prepared blank, and solving the problems caused by the slurry and the mold cavity. The air in the interior itself, as well as the pressure grouting method using compressed air, will cause the formed blank to contain pores, bubbles, etc., which will seriously affect the quality of the prepared blank.

Abstract

The invention relates to the technical field of ceramic forming, and discloses a grouting process. The process comprises the following steps: step 1, slurry preparation: uniformly mixing and stirring various raw materials according to a ratio to prepare raw material slurry; step 2, mold assembling: selecting a corresponding mold, closing the mold, and then integrally mounting and fixing the mold on a turntable of a centrifugal machine; step 3, grouting, injecting the raw material slurry prepared in the step 1 into a mold cavity of the mold in the step 2 through compressed air pressurization equipment; and 4, centrifugal exhausting: separating a grouting opening of the mold from the compressed air pressurization equipment, and sealing the grouting opening of the mold. According to the grouting process, through the manner of combining pressure grouting and centrifugation, the compactness of a blank can be greatly improved, bubbles and air holes in the blank can be reduced, and the quality of the prepared blank is effectively improved.

Description

technical field [0001] The invention relates to the technical field of ceramic molding, in particular to a grouting process technology. Background technique [0002] Grout molding is based on the physical characteristics of porous plaster molds that can absorb water. The ceramic powder is formulated into a fluid slurry, and then injected into a porous mold (mainly a plaster mold), and the water is formed after being absorbed by the mold (gypsum). A uniform mud layer with a certain thickness is formed, and a green body with a certain strength is formed during the dehydration and drying process. This method is called grouting. [0003] At present, in order to improve the density of the blank and shorten the grouting time, the common method is to use compressed air to press the mud into the model, but due to the air in the mud and the mold cavity itself, and the pressure of the compressed air to grout Both methods will lead to air holes, air bubbles, etc. in the formed blank, ...
