Problems solved by technology

[0003] There are also corresponding technologies to solve slagging in the existing technology, such as the invention patent: a high-temperature anti-slagging anti-slagging composite material, which improves the performance of high-temperature anti-slagging, but considering the complexity of materials in urban waste, especially kitchen waste If it is placed for a long time, it will produce a certain degree of corrosion. Therefore, it is necessary to conduct in-depth research on corrosion resistance on the basis of improving high-temperature slagging resistance to improve the durability of the device.

Abstract

The anti-slagging corrosion-resistant high-temperature composite coating is prepared from the following components in parts by weight: 20 to 30 parts of corundum fine powder specification mixture, 2 to 5 parts of ceramic powder with the particle size of 0.01 to 0.025 mm, 10 to 15 parts of barium metaborate, 15 to 20 parts of nano silicon dioxide, 2 to 6 parts of quartz powder, 0.5 to 1 part of nano yttrium oxide with the particle size of 30nm, 1 to 2 parts of nano cerium oxide with the particle size of 30nm, 15 to 20 parts of binding agent, 0.2 to 0.5 part of dispersing agent and 1 to 5 parts of anti-settling aid, 10 parts of fatty alcohol-polyoxyethylene ether, 2-5 parts of sodium nitrite and 25 parts of FeCl. The problem that an existing garbage incinerator inner wall coating cannot have corrosion resistance while certain slagging resistance and high temperature resistance are guaranteed is solved.

Description

technical field [0001] The invention relates to the technical field of anti-slagging composite materials, in particular to a high-temperature corrosion-resistant and anti-slagging composite material and a preparation method thereof. Background technique [0002] With the continuous development of the economy, electricity consumption continues to rise. Among the existing power generation methods, thermal power generation still ranks first. On the one hand, the incineration of municipal waste can be used for power generation, and on the other hand, it can also clean up the garbage generated by the city. The waste materials incinerated in urban waste power plants are complex, and their types, quantities and heat content are also very different. After incineration, the ash contained in the generated flue gas is viscous and easily adheres to the surface of the heating surface. , adhering to the furnace wall to form a tight slag layer, which gradually accumulates and thickens is ...
