Problems solved by technology

[0003] In the prior art, the coating 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 has the disadvantage of anti-contamination Coking, high temperature corrosion resistance, and poor flow rate wear resistance
Single layer, single color, high maintenance cost
The reciprocating sand blasting affects the service life of the substrate, and the harsh construction environment in the furnace and high-altitude operations have adverse effects on the physical and mental health of construction workers

Abstract

The invention discloses a black body anti-coking ceramic recognition coating layer and a preparation method thereof. The ceramic recognition coating layer is composed of a base layer and a surface layer, the base layer is white, and the surface layer is green; a coating for forming the base layer comprises zirconium dioxide, aluminum oxide, magnesium oxide, lithium fluosilicate, manganese powder,cerium oxide, lanthanum oxide, sodium silicate, potassium silicate, magnesium hexametaphosphate, aluminum hexametaphosphate, bentonite, clay, cured resin, modified inorganic powder and a reactive diluent; a coating for forming the surface layer comprises a ZS high-temperature-resistant far infrared radiation coating, aluminum silicate, a high-temperature binder, bentonite, clay, brown fused alumina, cordierite, a coloring agent and a dispersing agent; according to the high-temperature-resistant far infrared radiation coating, a strong radiation material contained in the high-temperature-resistant far infrared radiation coating radiates far infrared waves with extremely strong penetrating power at high temperature, so that molecules of a heated object absorb the waves to generate energy level transition, absorbed energy is uniformly heated, the heating time is shortened, and energy is fully saved.

Description

technical field [0001] The invention relates to the technical field of ceramic identification coatings, in particular to a black body anti-coking ceramic identification coating and a preparation method thereof. Background technique [0002] Traditional ceramics mainly refer to ceramics, glass, cement and refractory materials. The chemical composition is silicate, so it is also called silicate material. Advanced ceramics in a broad sense include artificial single crystal, amorphous state, ceramics and their composite materials, semiconductors, refractory materials and cement, also known as inorganic non-metallic materials; high-performance ceramic coating technology is composed of high-performance ceramic materials, advanced composite materials The fringe science, which is derived from the intersection with modern surface engineering technology, is a vigorous branch of disciplines in the field of contemporary new technology, and has a wide range of applications in various fi...
