Abstract

The invention relates to a wear-resistant and anti-corrosion puddle which is characterized by comprising a material A and a material B. The material A comprises the following components of epoxy resin, metal silicon powder, brown aluminum oxide, nanometer silicon carbide, silicon carbide, and silicon corundum; and the material B comprises the following components of a curing agent, the metal silicon powder, the brown aluminum oxide, the nanometer silicon carbide, the silicon carbide, the silicon corundum and green carbon. According to the wear-resistant and anti-corrosion puddle provided by the invention, the material A and the material B are mixed and constructed in field, so as to achieve simple and convenient construction operation, strong integrity after curing, thermal shock resistance, oxidation and erosion resistance, and good wear resistance and acid resistance. Therefore, a fire-resistant and wear-resistant lining material in operation is prevented from being damaged and released; the continuous and safe operation of a boiler is ensured; the maintenance working capacity is reduced; and the operation cost is reduced.

Description

technical field [0001] The invention relates to a refractory material, in particular to a wear-resistant and anti-corrosion mortar. Background technique [0002] Circulating fluidized bed boilers have the advantages of good fuel adaptability, high combustion efficiency and good environmental performance, and have been rapidly developed in China in recent years. So far, there are nearly 3,000 circulating fluidized bed boilers in design, construction and operation in China. At present, circulating fluidized bed boilers that have been put into operation generally have problems such as wear and tear of refractory and wear-resistant lining materials, wear of metal heating surfaces, and failure of auxiliary equipment. The damage and falling off of refractory and wear-resistant lining materials of circulating fluidized bed boilers often cause boiler accidents and shutdown, which affects the continuous and safe operation of boilers, increases the maintenance workload of boilers and...
