Brown fused alumina grit is commonly associated with refractory materials, sandblasting and polishing, and abrasive tools. However, it also finds numerous applications within the furniture industry, primarily in surface treatment and decorative processes.
Applications of Brown Aluminum Oxide Sand in the Furniture Industry
1. Wood Surface Sanding and Polishing
Function: Leveraging the high hardness of brown aluminum oxide sand (second only to diamond and silicon carbide), it rapidly removes burrs, old paint layers, and adhesive residue from wood surfaces.
Effect: Achieves a smooth, even finish conducive to painting, spraying, or veneering.
Common Applications: Base layer sanding for solid wood and panel furniture.
2. Treatment of Metal Furniture and Fittings
Sandblasting for rust removal: Removes rust and oxide scale from wrought iron furniture and metal fittings.
Surface strengthening: Creates uniform surface roughness to enhance corrosion resistance and improve coating adhesion.
Decorative effect: Premium metal furniture may undergo brown fused alumina sandblasting to achieve a satin finish or brushed effect.
3. Glass and Stone Worktop Finishes
Glass Frosting: Blasting glass surfaces with brown fused alumina creates a frosted effect, commonly used for cabinet doors and coffee table tops.
Stone Treatment: Marble and engineered stone worktops can be sandblasted to achieve anti-slip properties or decorative textures.
4. Eco-Friendly Furniture Processing
Water-Based Paint Furniture: Lightly sandblast with brown fused alumina prior to water-based paint application to significantly enhance paint film adhesion.
Environmental Benefits: Compared to chemical cleaning, sandblasting leaves no chemical residues, making it a more eco-friendly process.
