Description

Ceramic product dry particle distribution process

Technical Field

The invention relates to the technical field of ceramic manufacturing, in particular to a dry particle distribution process of a ceramic product.

Background

Modern antique ceramic tiles are various in types and colorful in surface process. In order to achieve the simulation effect closer to the material, most of the materials are subjected to stone simulation effect by adding dry particles on the surface of a die or adding dry particles on the surface of an ink-jet glue. Wherein, the stone-like product that the mould face adds the dry grain and forms exists the shortcoming: each tile was identical with no texture change, and comparative engraving was installed either on the top wall or on the bottom, as shown in figure 1. Although the stone-like product formed by adding the dry particles with the ink-jet glue can be changed according to the change of ink-jet patterns, the stone-like product has a single expression form, can only be provided with raised lines or dot bricks, and has a complex production process and high production cost.

As a further illustration of the above scheme, the specification of the tile product covers 600 x 600-1200 x 1200.

The invention has the beneficial effects that:

firstly, the invention utilizes a material distribution system of a press to add natural dry particles of a dry particle pattern grid and is assisted with micro powder for filling and forming, has the advantages of lower production cost and simpler production process, is completely different from the existing production process, and each piece of product can be changed, and the product can be natural.

And secondly, before the green brick is dried, the green brick is lightly ground on the surface of the green brick body, dry particles in the pattern lines are blown off by wind, a natural mould surface can be formed, the surface crack effect is natural, the product effect is closer to the surface of a natural stone plate, the splitting feeling and the washing or pickling stone surface feeling of the natural stone are achieved, the texture is smooth, and the preparation of an antique surface is facilitated. In addition, the depth, width and width of the line can be controlled by changing the adding amount of the dry particles of the cloth.

And thirdly, firing and molding the product, and polishing to obtain the polished brick, wherein the polished brick has the characteristics of high brightness and high hardness, and the polished product can form a dry grain pattern effect of natural glaze filling and has dark flower textures.
