White Fused Alumina Micropowder for Thermal Insulation Coatings Chemical Composition of White Fused Alumina Micropowder Affecting the Performance of Thermal Insulation Coatings Al₂O₃: ≥ 99.2–99.7% Na₂O: ≤ 0.25% Physical & Chemical Indicators of White Fused Alumina Micropowder for Thermal Insulation Coatings Color: Pure white; whiteness ≥ 88, will not cause discoloration for light-colored / white

I. Basis for selecting alumina / white fused alumina grades Grade selection depends on the target abrasion resistance of the finished wear-resistant melamine paper. Abrasion performance is directly related to particle size: Coarser particles deliver better abrasion resistance but reduce the transparency of melamine paper. Finer particles offer relatively lower abrasion resistance while significantly improving

Process Parameters of White Fused Alumina 220# (F220/220 Mesh) for Alloy Tool Sandblasting 1. Basic Information of Abrasive White Fused Alumina Material: White Fused Alumina (WA) fused alumina Grain Size: 220# / F220 / 220 Mesh fused aluminum oxide Main Composition: Al₂O₃ ≥ 99.5% corundum Mohs Hardness: 9.0 Features: Iron-free contamination, good self-sharpening performance and

Improve Wear and Scratch Resistance With a Mohs hardness of 9.0, white fused alumina powder forms a rigid hard skeleton inside the coating, greatly enhancing the coating’s resistance to friction, scouring and scratching, and extending the service life of the paint film. Increase Paint Film Hardness White fused alumina powder effectively increases the pencil hardness

White Fused Alumina Micropowder for Coatings？ White Fused Alumina (WA)/white fused aluminum oxide/white corundum /WFA /WA It features high hardness, superior wear resistance, high temperature resistance, acid and alkali resistance, pure white color without black residue and uniform particle size. It is mainly used for five core functions: wear resistance, anti-slip, anti-corrosion, high temperature resistance

Influence of White Fused Alumina Grain Size on Sandblasting Effect of Semiconductor Quartz Products 1. Coarse Grain Size (White Fused Alumina F60/F80/F100) Excessively high surface roughness Large alumina grains deliver strong impact force, forming deep pits and rough textures on quartz surfaces with excessive Ra value. This weakens adhesion of subsequent coating and film layers,
