The Aluminum oxide powder for laminate flooring needs to meet the following indicators to be suitable for adding to the wear-resistant coating:
- Whiteness: The whiteness of aluminum oxide should be above 80. So the Al2O3 powder will not affect the color of the wear-resistant glue.
- Fluidity: Since alumina powder needs to be added to the glue, it needs to have good fluidity. The acid pickled and suspension Treated aluminum oxide powder has fewer impurities, so it has better dispersibility and fluidity.
- Anti-slip: There are many kinds of aluminum oxide on the market. Raw industrial alumina powder, calcined alumina powder, and fused alumina powder are all available from many resources. Aluminum oxide powder for laminate flooring produced by a high-temperature melting process has obvious advantages. Fused aluminum oxide has the characteristics of high hardness (Mohs hardness 9.0) and high wear resistance.
- High-temperature resistance and corrosion resistance: The refractory temperature of fused aluminum oxide is high. It will not melt even at a high temperature up to 1850 degrees. It has strong chemical stability and does not react with strong acids.
- Particle size consistency: Good particle size distribution will help wear-resistant powder and the suspending agent scatter in the glue evenly.
