Embodiment Construction
[0011] 1. First, mix bauxite, lithium-based bentonite, attapulgite clay, high-temperature-resistant cement talcum powder, kaolin, pyroxene, and potassium feldspar evenly, place it in a high-temperature rotary container, and heat it to 1250°C for calcination for 2 hours. , so that the lattice of inorganic powder is turned, and impurities are removed.
[0012] 2. Pour water glass, deionized water, dispersing aid, and film-forming aid into the container and stir evenly without stratification.
[0013] 3. Mix the powder and liquid at a ratio of 1:1 and paint. The temperature resistance of the coating can reach 1200°C, and the hardness can reach 8H (after it is fully cured).

Abstract
A wear-proof and high-temperature-resistant ceramic coating is a high-temperature-resistant, wear-proof and energy-saving industrial coating used for metal and prepared from an inorganic modified solution and nano inorganic ceramic filler. The coating can provide a wear-proof, anti-impact, high-adhesion, anticorrosion and tough protecting coating for equipment, is good in compactness and high in permeability resistance, has the capability of working for a long time under severe conditions and can be used for a long time in oilfield wastewater and corrosive media such as acid, alkaline, salt and the like; meanwhile, the coating doesn't pollute the environment, is inorganic, green and environment-friendly and can be widely applied to the fields of metallurgy, petrochemical engineering, the cement industry, natural gas extraction and even aerospace aviation.
Description
technical field [0001] The wear-resistant and high-temperature-resistant ceramic coating is a high-temperature-resistant, wear-resistant and anti-corrosion coating with a temperature resistance of 1200°C, a strength of 150Mpa, excellent anti-corrosion performance, and extremely wear-resistant and other functions. Background technique [0002] In the production process of metallurgy, electric power, and chemical industry, many equipment and pipelines are in poor working conditions for a long time, especially the superheater tubes, reheater tubes, water cooling tubes, and economizer tubes (commonly known as "four tubes") of thermal power plant boilers. ”) working conditions are extremely harsh. For example: the temperature in the boiler is as high as 1200°C, 30% of the solid particles of 8-16 mesh are contained in the high-temperature gas, and the flow rate is about 10m / s. In order to prevent the synergistic effect of high-temperature oxidation and wear of the pipe wall, the ...
