Application of white corundum in floor coatings
Due to its excellent physical and chemical properties, white corundum has the following core application value and technical characteristics in floor coatings:
1. Core functional characteristics
Improved wear resistance
White corundum has a Mohs hardness of 9.0 and a Vickers hardness of 2000-2200kg/cm³. Adding it to the coating as a wear-resistant additive can significantly improve wear resistance and extend the life of the floor by 2-3 times.
Enhanced anti-slip safety
White corundum particles are evenly distributed on the surface of the coating to form a microscopic rough structure and increase the friction coefficient, which is especially suitable for high-traffic areas such as industrial plants and parking lots.
Optimized weather resistance and corrosion resistance
White corundum has strong chemical stability (Al₂O₃ purity 99.5%), can resist acid, alkali, salt and extreme temperature erosion, and is suitable for harsh environments such as chemical plants and cold chain storage.
Improve the flatness and hardness of the coating
White corundum micron-sized particles (180 mesh, 220 mesh, 240 mesh, 280 mesh, 320 mesh, 400 mesh pure or graded) fill the micropores of the coating to improve the surface finish; at the same time, increase the overall hardness and reduce scratch damage.
2. Construction process and compatibility
Flexible construction method
Spreading process: Spread white corundum particles evenly when the coating is not cured and embed them into the coating;
Mixing process: White corundum powder is directly mixed with epoxy resin (such as mid-coat), stirred and then painted.
Wide adaptability
White corundum is compatible with epoxy, water-based epoxy and other floor systems, and can be used in mortar layer or surface layer.
3. Comprehensive benefits
Aesthetics: White corundum whiteness ≥ 85%, adapted to modern industrial aesthetics;
Economical: Reduce maintenance frequency, and reduce comprehensive costs by more than 30%;
Safety: Reduce the risk of accidents through anti-slip and corrosion-resistant design.
