Application of white aluminum oxide as a wear-resistant additive in the coating industry
Due to its high hardness (Mohs hardness 9.0), wear resistance and chemical stability, white aluminum oxide has many application values as a wear-resistant additive in the coating industry, as shown below:
I. Core performance improvement
Enhance wear resistance
White aluminum oxide significantly extends the life of the coating by improving the hardness and wear resistance of the coating, and is especially suitable for high-friction scenarios (such as flooring and automotive coatings)
Increase coating hardness
Its high hardness can resist scratches and mechanical wear, and is suitable for industrial equipment, mechanical coatings and other fields with high surface hardness requirements.
Optimize adhesion
Fine particles can fill the gap between the coating and the substrate, enhance adhesion and reduce the risk of falling off.
II. Application scenario expansion
Floor coating
Used in industrial plants, parking lots and other places, the anti-slip property, chemical corrosion resistance and pressure resistance are improved by adding white aluminum oxide particles.
Automotive coating
Improve the wear resistance and weather resistance of the body coating, and reduce surface damage caused by friction or environmental erosion.
Industrial protective coatings
In anti-corrosion coatings, white corundum can enhance the wear resistance and high temperature resistance of the coating, and is suitable for the protection of metallurgical and mining equipment.
Ⅲ. Additional performance optimization
Improve surface texture
White aluminum oxide powder can improve the gloss of the coating, and control the surface roughness by adjusting the particle size to meet the needs of decoration or anti-slip.
Anti-slip function
The particle distribution forms a microscopic concave-convex structure, which increases the friction coefficient and is suitable for anti-slip coatings such as stairs and bathrooms.
Environmental protection advantages
As an inorganic filler, it is non-toxic and pollution-free, and meets the production requirements of low-VOC environmentally friendly coatings.
Ⅳ. Precautions
Product selection: It is necessary to select the appropriate particle size (such as micropowder or particles) and addition ratio according to the coating formula to avoid affecting the construction performance and coating uniformity.
Dispersion process: It is necessary to ensure that the white corundum is evenly dispersed in the coating to prevent the particles from settling or agglomerating and affecting the performance.The application of white corundum not only improves the functionality of the coating, but also expands the applicable scenarios of coating products through comprehensive performance optimization, becoming one of the important additives in the field of wear-resistant coatings.
