Abrasion resistant ceramic coating

Abstract

The invention discloses a brushing-proof abrasion-proof and erosion-proof ceramic paint, which is characterized by the following: selecting at least one of electric-melting brown corundum, electric-melting subwhite corundum, electric-melting white corundum, carborundum and electric melting mullite with different grain sizes as main material and at least one of compact corundum, electric-melting subwhite corundum, electric-melting white corundum, carborundum, silicon nitride and boron nitride as auxiliary material; using CA50 calcium aluminate cement or pure calcium aluminate cement as binder and nanometer micro-silica powder and active alpha-Al2O3 micropowder as reinforcer; making hyperdrying active high-effective dehydragent, sodium citrate and sodium hexametaphosphate as composite additive; loading in the strength stirrer to stir 12-17min; blending evenly; packing.

Description

technical field

[0001] The invention relates to a coating in the field of composite materials, in particular to a ceramic-like anti-scouring, anti-abrasion and anti-corrosion wear-resistant coating. Background technique

[0002] In many industries such as cement building materials, thermal power generation, metallurgy and mining, petrochemical industry, etc., there are a large number of equipment or devices in operation, and some parts are scoured, worn or corroded by various media. Corrosion reduces the service life of these equipment or devices, directly leads to more downtime for equipment maintenance, high maintenance costs, and low equipment operation rate; at the same time, it also leads to adverse consequences such as decreased equipment efficiency, increased power consumption, increased production costs, and serious environmental pollution. .

[0003] To solve the above problems, it is currently limited to the parts of these equipment that are washed, worn or corrod...
