Abstract

The invention relates to an environment-friendly high-tech powder material for a ceramic roller. The powder material is prepared from the following raw materials in parts by weight: 100 parts of high-purity fused quartz powder, 20-50 parts of aluminum-doped zinc oxide, 25-35 parts of lanthanum strontium manganese oxide, 10-18 parts of titanium diboride, 20-30 parts of boron carbide, 5-8 parts of carbon black and 8-15 parts of aluminum oxide. The preparation method comprises the following steps: weighing the raw materials in parts by weight according to the formula, putting the raw materials into a planetary ball mill for ball milling for 4-5 hours, and drying to obtain a mixed powder; and then putting the mixed powder into a plasma activation calcining furnace to be calcined for 1 to 2 hours so as to obtain the environment-friendly high-tech powder material for a ceramic roller. The powder material disclosed by the invention is a novel functional ceramic powder material and can be used as a powder material for a dielectric and piezoelectric multiphase quartz ceramic roller; and the multiphase quartz ceramic roller disclosed by the invention has the advantages of high temperature resistance, water vapor resistance, good dielectric property and piezoelectric property, stable phase structure, good uniformity, high compactness and stable and superior performance, and has great production benefits and practical values.

Description

technical field [0001] The invention belongs to the technical field of ceramic rollers, and in particular relates to an environment-friendly high-tech powder material for ceramic rollers and a preparation method thereof. Background technique [0002] The ceramic roller is a combined component composed of porcelain body, bearing, shaft and plastic labyrinth seal ring. The ceramic roller is a key component in the glass horizontal tempering furnace, mainly used for carrying and transporting glass in the glass horizontal tempering furnace. The quartz ceramic roller is made of high-purity fused quartz, which has high volume density, high strength, small thermal expansion, good thermal shock stability, high dimensional accuracy, no deformation at high temperature, long service life, and no pollution to glass. However, a large amount of pollutants will be generated during the preparation of powder materials. If not handled properly, the pollutants will have a great impact on the at...
