Application of white corundum in powder coating industry
1. Optimization of core functions
Enhance the wear resistance of coatings
The hardness of white corundum powder is 9.0, close to diamond. As a base material, it can significantly improve the anti-friction ability of coatings and extend their service life. Its evenly distributed particles can form a dense protective layer to reduce shedding caused by wear.
Improve corrosion resistance
White corundum has stable chemical properties, can resist acid and alkali erosion, protect the substrate from corrosion damage, and is suitable for harsh environments such as chemical equipment and marine engineering.
Improve high temperature resistance
The melting point of white corundum is as high as 2050°C. It maintains the stability of the coating in high temperature environments, avoids deformation or shedding, and is suitable for metallurgy, high-temperature furnaces and other fields.
Optimize the appearance and texture of the coating
By adjusting the particle size distribution of white corundum powder, the surface flatness and finish of the coating can be improved, and the decorative effect can be enhanced. Its fine powder characteristics can also enhance the gloss of the coating.
2. Improved process performance
Enhanced adhesion and hardness
White corundum powder can fill the pores of the coating, improve the adhesion strength with the substrate, and prevent peeling; at the same time, it increases the hardness of the coating, making it more scratch-resistant. Improved construction performance
White corundum has good dispersibility and can be evenly distributed in the coating, reducing the difficulty of spraying or brushing, and forming a dense and uniform coating structure. Environmental protection advantages
Non-toxic and pollution-free characteristics meet environmental protection standards and are suitable for food machinery, medical equipment and other fields with high environmental protection requirements.
3. Typical application scenarios Construction field : Used for exterior wall coatings to improve weather resistance, and floor coatings to enhance anti-slip and wear resistance. Industrial equipment : Manufacture wear-resistant and anti-corrosion coatings, such as bearings, crusher parts, etc., to extend the life of equipment. Automobiles and ships : Car body coatings improve scratch resistance, and ship coatings enhance salt spray corrosion resistance. Fire retardant coatings : As a fire-resistant additive, it improves the fire resistance level and high temperature stability of the coating.
4. Technology Development Trend
The current application of white corundum is developing towards precise particle size control and composite functional coatings, such as combining polyester resin technology to develop new powder coatings that are both wear-resistant and weather-resistant.
