Abstract

The invention discloses a making method of a high strength ceramic plate. Raw materials of the ceramic plate comprise, by weight, 50-80 parts of kaolin, 8-12 parts of aluminum nitride, 3-5 parts of talcum powder, 6-8 parts of cellulose pulp, 5-15 parts of quartz powder , 0.1-1 part of a coloring agent and 1-2.5 parts of a foaming agent. The making method of the ceramic plate comprises the following steps: mixing the raw materials, immersing the obtained mixture in water, beating, screening, dehydrating, rolling, forming a blank, drying, calcining, cooling, and polishing to make a finished product. Aluminum nitride is added to the raw materials, so the strength of the ceramic plate is improved; a small amount of the foaming agent is added, and the foaming agent reacts in the calcining process to generate a gas, so a porous structure is formed in ceramic in order to realize a light weight effect; an enamel layer at the surface of the ceramic plate increases the wear resistance of the surface of ceramic; and the whole ceramic plate product has the advantages of high temperature resistance, wear resistance, high strength, thinness and light weight.

Description

technical field [0001] The invention relates to the technical field of laboratory ceramic plates, in particular to a preparation method of high-strength ceramic plates. Background technique [0002] At present, ceramic plates made of ceramic materials have been widely used in laboratory equipment. Due to the requirements of the working environment of the laboratory, the requirements for the physical and chemical performance indicators of ceramic plates are also getting higher and higher. At present, ceramic plates are relatively heavy, have low strength, and are easily broken during transportation, installation and use; in addition, the thermal insulation effect is also poor. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a method for preparing a high-strength ceramic plate with simple process, high temperature resistance, wear resistance, good strength and other physical and chemical pro...
