Effects of Silane Coating on the Properties of White Corundum
The effects of silane coating on the properties of white corundum are primarily reflected in the following aspects:
Physical Properties
Hardness and Wear Resistance: The treated surface forms a silicon coating, significantly improving the hardness and wear resistance of white corundum, enhancing its overall wear resistance.
Hydrophilicity: Improves the hydrophilicity of the white corundum surface, making it suitable for aqueous media applications.
Corrosion Resistance: The silicon coating enhances chemical stability, slowing down the degradation of white corundum in harsh chemical environments.
Mechanical Properties
Adhesion and Bonding: Improves the bonding strength of white corundum to other materials (such as adhesives), enhancing the overall performance of products such as abrasive tools.
Toughness: The silicon coating acts as a cushioning agent during impact, reducing the risk of white corundum particle breakage.
Applications
Wear-Resistant Flooring: Silane-coated white corundum is often used in the manufacture of wear-resistant flooring to improve its wear and corrosion resistance.
Sandblasting: White corundum abrasive treated with a high-temperature sintering process achieves a hardness of HV1800-2200, increasing sandblasting efficiency by 20% and raising the surface roughness compliance rate from 85% to 95%.
Precision Casting: White corundum abrasive with an angular coefficient of 1.3 reduces surface defects in castings and improves yield by 12%.
