Problems solved by technology

However, the patent has the disadvantage that its operation procedure is intermittent; the extruded clay billet is a hollow cylinder, which needs to be cut horizontally, cut vertically, and unfolded before entering the next calendering process, which cannot adapt to the continuous operation of the production line. In addition, the structure of the molding device is complex, and the product has no surface glaze layer, which is not resistant to stains and poor corrosion resistance

Abstract

The utility model relates to a fiber porcelain board for interior and exterior wall decoration, which belongs to clay products. It is characterized in that the clay of the base layer is mixed with inorganic mineral fibers, and one side of the base layer is provided with a composite surface layer including a bottom glaze layer and a top glaze layer; the ratio of the length, width, and thickness of the porcelain plate is 3-1.5:2- 1: 0.008-0.003. The forming process is to use a vacuum mud mixer with a plate-shaped forming die. The outlet of the mud mixer is equipped with a variable-diameter deformation pipe. The ratio of the length and width of the outlet of the plate-shaped forming die is 1.8 to 0.8:0.1 ~0.03. The raw clay is extruded into a plate-shaped original body, rolled and stretched to obtain a continuous plate-shaped wet clay plate, cut horizontally, dried, bisque-fired, glazed on the surface, and fired to obtain the fiber porcelain plate of the present invention. The surface structure has high hardness and can be polished, dense, antibacterial and antifouling, and the product performance is greatly improved. The molding process steps are simple and the production efficiency is high. The forming equipment has simple structure and long service life.

Description

technical field [0001] The invention belongs to the field of clay products, and in particular relates to a ceramic plate product used for interior and exterior wall decoration, a molding process and equipment. Background technique [0002] Disclosed on September 2, 1998, the Chinese patent with the publication number CN 1191853A discloses a "large-scale flat ceramic sintered body and its manufacturing method and manufacturing device". When using a blender to extrude clay billets, use a method that does not apply rigid force from the side; moreover, use a blender in which the mandrel shaft of the extrusion part can rotate freely; the molding die is cylindrical, and the extrusion The clay body produced is also cylindrical. After the clay body is formed, it is cut horizontally, cut vertically, and unfolded flat. Then, it is rolled, dried, and fired to obtain the finished product. However, the patent has the disadvantage that its operation procedure is intermittent; the extrude...
