Abstract

The invention provides a ceramic identification coating suitable for a metal substrate and a preparation method of the ceramic identification coating. The ceramic identification coating is particularly suitable for a metal substrate in a power plant boiler. The ceramic identification coating is composed of a base layer and a surface layer. The base layer is also called as an identification layer and is white, and the thickness of the base layer is 0.10-0.15 mm; the surface layer is green, and the thickness of the surface layer is 0.10-0.15 mm; and the color difference between the surface layerand the base layer is obvious, and an identification degree is high. In the using process of the ceramic identification coating, sand blasting is not needed when the base layer part is exposed and the surface layer is re-sprayed; and after floating ash on a heating surface is blown and cleaned through high-pressure air or high-pressure water, surface layer paint can be directly sprayed to the part, where the white base layer is exposed, of the ceramic identification coating. The ceramic identification coating has the functions of resisting high-temperature corrosion, resisting dirt adhesion and coking and improving heat exchange efficiency, the service life of the substrate can be effectively prolonged, the manpower and economic cost of subsequent maintenance is remarkably reduced, and long-life-cycle protection of the heating surface is achieved.

Description

technical field [0001] The invention relates to a ceramic identification coating, which is suitable for metal substrates, especially metal substrates in power plant boilers, specifically by providing a ceramic identification coating, which is composed of a base layer and a surface layer, and the base layer is white , the surface is green. Background technique [0002] In the prior art, the coatings on the heating surface and fire-facing surface of high-temperature radiation metal substrates used in power plant boilers, industrial boilers, and kilns in industries such as electric power, petroleum, petrochemical, and metallurgy have the disadvantage of anti-contamination Coking, high temperature corrosion resistance, and flow rate wear resistance are poor. Single layer, single color, high later maintenance cost. Reciprocating sand blasting affects the service life of the substrate, and the harsh construction environment in the furnace and high-altitude operations have advers...
