Preparation method of matrix ceramic powder for additive manufacturing of Longquan celadon

Abstract

The invention discloses a preparation method of body ceramic powder for additive manufacturing of Longquan celadon. The preparation method comprises the following steps: with deionized water serving as a dispersion medium, polyvinyl alcohol serving as an adhesive, polyethylene glycol serving as a dispersing agent, n-butyl alcohol serving as a defoaming agent and silicon carbide sand serving as a ball-milling medium, Ge kiln body ceramic powder is subjected to ball-milling and mixing, and slurry is obtained; the slurry is subjected to spray drying, and the body ceramic powder is obtained. The body ceramic powder prepared with the method has a good flow characteristic, spreadability and compactness.

Description

technical field [0001] The invention belongs to the technical field of additive manufacturing, and in particular relates to a method for preparing matrix ceramic powder for additively manufacturing Longquan celadon by a spray granulation method. Background technique [0002] Longquan celadon is as green as jade, as bright as a mirror, as thin as paper, and as loud as a chime. Longquan celadon is mainly attracted by its glaze color, and it is the most famous color glazed porcelain variety. Longquan kiln is a famous celadon kiln with the longest firing period, the widest distribution of kiln sites, the highest product quality, the largest production scale and the largest export scope in the history of Chinese ceramics. It has an important position in the history of Chinese ceramics. [0003] The traditional production method of Longquan celadon is mainly manual production. Celadon production needs to go through fourteen main processes from raw materials, formula processing, m...

Problems solved by technology

However, it should be noted that there are many problems in the traditional manufacturing process of Longquan celadon: 1) The production process is complicated and lengthy, and the production process is complicated and trivial, which makes it difficult to control the structure and performance of Longquan celadon products, and it is difficult to balance the craftsmanship and artistry of the product; 2) The green body is formed Limited by the molding method, the shape of the green body is simple, the uniformity of the green body is not easy to control, and it is easy to deform and crack; 3) Manual operation is labor-intensive, the product output is low, and the yield and reliability of the finished product are not high, which restricts the scale effect of high-end products; 4) The application of advanced technologies such as information technology, computer technology, and intelligent technology in celadon is still lagging behind, and technological innovation is insufficient

These factors severely limit the development and application of new materials and new products for Longquan celadon, and greatly restrict the development of Longquan celadon's diversified industries.
