What coatings are black silicon carbide suitable for?
Due to its high hardness (Mohs hardness 9.15), corrosion resistance, high temperature resistance and other characteristics, the application scenarios of black silicon carbide in coating production are as follows:
1. Wear-resistant coatings
Mechanical protective coatings: used for surface coatings of mechanical parts, tools, bearings and other components, which can significantly improve wear resistance and service life.
Wear-resistant floor coatings: added to floor coatings as wear-resistant aggregates, suitable for industrial plants, warehouses and other occasions requiring high wear resistance.
2. Anti-corrosion coatings
Chemical equipment protective coatings: used in anti-corrosion coatings for chemical equipment, reaction vessels, etc., to enhance the resistance of coatings to chemical corrosive media.
Marine and marine coatings: added to ship paints and marine anti-corrosion coatings to improve the corrosion resistance of coatings in salt spray and humid environments.
3. Special functional coatings
Teflon coatings: In areas such as building materials where fineness is not required, black silicon carbide 360 mesh can be used instead of green silicon carbide as micropowder for Teflon coatings such as non-stick pans and cookware.
High temperature coatings: Suitable for surface coatings of high-temperature furnaces, refractory materials, etc., with excellent high temperature resistance.
4. Functional industrial coatings
Electronic insulating coatings: Because silicon carbide micropowder has high resistivity, it can be used for insulating coatings of electronic components and semiconductor materials.
UV light-curing coatings: As a wear-resistant additive, it improves the surface hardness and scratch resistance of light-curing coatings.
5. Environmental protection and decorative coatings
Architectural decorative coatings: Used in square paints, road paints, etc. to improve the wear resistance and weather resistance of coatings.
Stone/ceramic coatings: Added to stone polishing coatings or ceramic glaze coatings to enhance surface finish and wear resistance.
Additional explanation
The advantages of black silicon carbide in coatings include:
High cost performance: Compared with green silicon carbide, black silicon carbide has lower cost and is suitable for areas with moderate requirements for wear resistance but cost control.
Process adaptability: Its particles are uniform and the content of magnetic substances is low, which can meet the requirements of coatings for dispersion and stability.
