The role of white fused aluminum oxide as a wear-resistant additive
As a wear-resistant additive, white fused aluminum oxide plays a key role in many fields with its unique physical and chemical properties, as shown below:
1. Improve material hardness and wear resistance
The Mohs hardness of white fused aluminum oxide reaches 9. After adding materials such as coatings, mortars or ceramics, it can significantly improve the surface hardness and wear resistance. Its high hardness characteristics effectively resist mechanical damage such as friction and scratches, and extend the service life of materials in heavy loads or high-frequency friction environments.
2. Enhance material adhesion and structural stability
When used as a filler, white fused aluminum oxide particles can form a close bond with the substrate, improve the adhesion of the coating to the substrate or the inside of the material, and reduce the risk of falling off. For example, in wear-resistant coatings, this property can prevent the coating from peeling off due to external forces and maintain long-term stability.
3. Optimize compressive and impact resistance
White fused aluminum oxide has both high hardness and toughness, and can withstand greater pressure and impact. After being added to mortar or ceramics, the compressive strength of the material is significantly improved, which is suitable for scenes such as bridges and industrial floors that need to bear weight or resist impact.
4. Improve corrosion resistance and chemical stability
White fused aluminum oxide has stable chemical properties and is resistant to acid and alkali corrosion. In chemical equipment coatings or ship coatings, it can effectively block chemical erosion as an additive to protect the substrate from maintaining performance in a corrosive environment.
5. Expand the adaptability of application scenarios
White fused aluminum oxide can be adapted to a variety of material systems, including:
Paint field: used in floor paint, automotive coatings, etc. to improve anti-slip and weather resistance;
Abrasive manufacturing: as a consolidated abrasive abrasive, improve metal processing efficiency and grinding accuracy;
Building materials: enhance wear resistance and compression resistance in mortar, suitable for heavy-loaded roads and industrial plants;
Ceramic industry: as an additive to improve the hardness and firing stability of ceramic products.
6. Optimization of construction and processing performance
The uniform particle size of white fused aluminum oxide micropowder can improve the fluidity and density of the material, such as improving workability in mortar, reducing pores, and enhancing impermeability. At the same time, its high glossiness can also optimize the surface texture of the coating.
Summary: White fused aluminum oxide has become an irreplaceable functional additive in the field of wear resistance through its comprehensive effects such as hardness enhancement, structural stability, and corrosion resistance, and is widely used in scenarios such as industrial protection, building materials, and precision processing.
