Application of chromite powder in the coating industry
The application of chromite powder in the coating industry is mainly reflected in the following aspects. Combined with its physical and chemical properties and processing forms of different mesh sizes, the main application scenarios are as follows:
1. High-temperature refractory coating
Improve refractory performance
Chromite powder can significantly improve the stability of coatings in high temperature environments due to its refractoriness exceeding 1900℃, ensuring that the coating does not soften or fall off at high temperatures, and is suitable for metallurgical kilns, glass furnaces and other equipment.
Enhance corrosion resistance
Its high hardness (Mohs hardness 5.5-6.5) and density (3.0-4.8g/cm³) give the coating excellent resistance to molten metal penetration and chemical erosion, especially for industrial scenes in contact with alkaline slag.
2. Industrial protective coatings
Weather resistance and corrosion resistance
The chemical stability of chromite powder can enhance the coating’s tolerance to ultraviolet rays, wind and rain, and acid-base media, and extend the service life of coatings for outdoor equipment, ships, etc.
Abrasion and scratch resistance
The high hardness can improve the mechanical strength of the coating and reduce the wear caused by friction or impact. It is suitable for floor coatings, mechanical equipment surface protection and other fields.
3. Functional coatings
Coloring and decorative coatings
200-325 mesh chromite powder can be used as a green or brown colorant for glass containers (such as beer bottles), ceramic glazes and decorative coatings to provide natural mineral color.
Special coating additives
Ultra-fine mesh (such as 2000-2500 mesh) chromite powder is used for ink pigments and high-precision printing coatings to enhance the dispersion and adhesion of pigments.
4. Application examples
Ceramic industry: As an additive for green glazes, used in tiles, handicrafts, etc. Glass industry: As a colorant for soda-lime glass containers, green glass products are produced. Casting and refractory materials: Used in casting coatings and refractory brick surface coatings to improve the ability to resist high-temperature molten metal erosion. The wide application of chromite powder in coatings is based on its unique high temperature resistance, chemical stability and coloring properties. Products with different mesh sizes can meet the diverse needs from basic protection to high-end decoration.
