Highly wear-resistant ceramic-metal compound paint for industrial pipeline and application method of paint

Abstract

The invention discloses a highly wear-resistant ceramic-metal compound paint for an industrial pipeline and an application method of the paint. The highly wear-resistant ceramic-metal compound paint comprises the following components: high-alumina cement, silicon carbide, silica, broken high-voltage electric porcelain, alumina micro powder, SiO2 micro powder and wind deposited sand, wherein the raw materials are smashed and uniformly mixed so as to prepare the finished product. The application method comprises the following steps: (1) preparing paint slurry; (2) preparing a paint material layer; (3) maintaining the paint material layer. According to the paint, industrial wastes, namely, waste electroceramics and wind deposited sand, are utilized in mass, so that the comprehensive resource utilization is facilitated, the environment can be protected, and the cost of the raw materials is greatly reduced. Through the use of the provided highly wear-resistant ceramic-metal compound paint, relatively obvious effects are played for industrial enterprise equipment operation rate improvement, maintenance cost reduction and enterprise economic benefit improvement.

Description

Technical field: [0001] The invention relates to a coating material and its application method, in particular to a highly wear-resistant ceramic-metal composite coating material for industrial pipelines and its application method. Background technique: [0002] In our country, there are a large number of metal pipelines in various industrial enterprises, such as iron and steel, cement, coal, electric power, chemical industry and other enterprises, most of which transport high-concentration and fine-grained materials. The wear of the material on the metal pipe is very large. Every year, the direct and indirect losses caused by pipeline wear are considerable. In the past, in order to improve the wear resistance of pipelines, enterprises have adopted various methods, such as welding wear-resistant steel plates on the surface of metal pipelines, and laying alumina ceramic patches on the inner surface of pipelines. Wait. Wear-resistant steel plates are expensive and wear-resist...

Problems solved by technology

The above three materials have their own advantages and disadvantages: 1. Wear-resistant cement is improved on the basis of high-temperature cement for refractory brick masonry. Due to the low mechanical strength and poor impact resistance of the materials used, the general service life is about half a year. For industrial enterprises, the service life is obviously too short, which affects the operation rate of the production line; 2. The wear-resistant ceramic coating part uses ceramic materials, and the mechanical strength has been improved. However, due to various reasons, at higher temperatures, it is easy to produce surface damage. Cracking, large area falling off, etc.

In addition, due to the large amount of brown corundum with high energy consumption, the resource and energy consumption is large, which is not conducive to environmental protection; 3. The high-temperature ramming material combines the advantages of the above materials and can work in a high-temperature environment, but the construction is difficult and professional. , and the construction thickness is large, the main function is the insulation of the cylinder, the price is expensive, and its wear resistance is only better than that of wear-resistant cement
