Ultrastrong abrasion-resistant micropowder combined coating

Abstract

The invention discloses a lining composite coating which is combined with micropowder. Used main materials include the following materials: carborundum, silicon carbide micropowder and aluminum oxide micropowder, wherein the addition amount of the carborundum accounts for 40%-50% of the total weight of the carborundum, the silicon carbide micropowder and the aluminum oxide micropowder, the addition amount of the silicon carbide micropowder accounts for 20%-30% of the total weight of the carborundum, the silicon carbide micropowder and the aluminum oxide micropowder, and the addition amount of the aluminum oxide micropowder accounts for 3%-5% of the total weight of the carborundum, the silicon carbide micropowder and the aluminum oxide micropowder. The lining composite coating disclosed by the invention has the advantages of long life, low cost, fast construction and good thermal shock and is more suitable for carrying out fast hot repair without stopping production.

Description

technical field [0001] The invention relates to an inner lining material used in cement, electric power and metallurgical industries, in particular to an inner lining composite paint mainly composed of superfine powder combination. Background technique [0002] In the pipelines, flue, dust collector, feeding hopper, feeding chute, powder separator and other equipment and conveying pipelines in cement, electric power, metallurgy, and other industries, due to the harsh working environment, high temperature, and high dust concentration, Acid and alkali erosion and wear are serious, especially in recent years, waste heat power stations have been added in the cement industry, and many elbows have been added to the layout of thermal power generation to increase ventilation power. Therefore, for the normal operation of the rotary kiln, the wind speed must be increased, which is even stronger. The wear and tear of the hot air duct is reduced, and the service life plummets.
