Application of White Fused Alumina in Floor Coating Industry
White fused alumina is used as a core functional filler in the floor coating industry, and its technical optimization and performance improvement are mainly achieved through the following characteristics:
1.Core functions and effects
Enhanced wear resistance
The Mohs hardness of white fused alumina reaches 9.0. Its high hardness and dense crystalline structure can significantly improve the anti-friction and anti-scratch ability of floor coatings and extend the service life of coatings.
Improved scratch resistance
The high purity and uniform particle distribution enable it to form a dense protective layer in the coating, reducing external mechanical damage
2.Material properties and process advantages
Low oil absorption and fluidity
After pickling, water washing and magnetic separation, the impurity content is low, and the oil absorption rate is only 1/3~1/2 of that of ordinary fillers, which is convenient for coating formula design and improves construction leveling.
Particle size adaptability
The commonly used models are 150#~320#, and the particle concentration is controlled by water washing or screening process to avoid scratches on the coating surface.
3.Application scenario expansion
High-performance flooring
Suitable for high-frequency wear scenarios such as industrial plants and parking lots, taking into account corrosion resistance and high temperature resistance requirements (the electrofusion process gives it high temperature stability).
Surface treatment optimization
The translucent crystalline characteristics can reduce the impact on the color of the coating, while improving the gloss uniformity of the polished floor.
4.Comprehensive performance comparison
| Characteristics | Advantages of white fused alumina |
| Hardness | Mohs 9.0, better than most mineral fillers |
| Process compatibility | Low oil absorption rate is suitable for epoxy, polyurethane and other resin systems |
| Durability Weather | resistance and chemical corrosion resistance are improved simultaneously |
Through the above characteristics, electrofused alumina has become a key additive in floor coatings to balance cost and performance, especially in industrial scenarios that require high-intensity and long-term maintenance.
