Carborundum powder for Oxidation-Resistant Coating
Black & green carborundum powder is a terrific ingredient for oxidation-resistant coating. Especially for the key components in industries such as power plants, mines, petrochemicals, and marine turbine equipment. The pipelines, kiln, critical conveying components, engine blades, and large pumps are always exposed to the corrosive environment. Wearing and anti-corrosion treatment of these components can improve their service life and reduce failure rates. In most cases, anti-corrosion and oxidation-resistant coatings with carborundum powder ingredients are suitable for pre-treatment and repair.
For example, in the desulfurization system of thermal power plants, the desulfurization pipeline contains highly corrosive liquids and the wear caused by slurry erosion is significant. There are a lot of acidic gases and hard particles in the medium conveyed by the flue, which can also cause strong wear and corrosion to the flue.
Carborundum powder including black and green colors adapted to coatings for its excellent properties as follows:
The carborundum powder has good chemical stability and can withstand the erosion of most acidic and alkaline substances.
The carborundum powder is a good refractory material. It can resist high temperatures of about 1800-1900 degrees. Carborundum could bear the shock and impact of thermal flow.
Carborundum powder has excellent antioxidant properties. Even at a high temperature of 1400 degrees silicon carbide can remain stable physical and chemical index. Carborundum crystal can form a protective layer on the surface to prevent oxidation, which has an anti-corrosion function at the micro level.
Carborundum powder gets high strength and hardness. It can withstand the impact of airflow or liquid, improving wear resistance.
Carborundum gets a low thermal expansion rate. It can protect the pipeline, valve, and other facilities from deformation and increase the service life.
Carborundum powder is also suitable for refractory mastic, anti-corrosion coatings, and modified resin anti-corrosion coatings. Typical applications include:
Black carborundum 320# grit for outtake repairing in power plant.
Black carborundum 400#-500# powder for desulfurized and kiln construction.
Green carborundum powder 1000#-3000# for anti-corrosion coating.
