Product Description

Applications for White Rigid Jade Sand:
Refined Grinding: White corundum is a primary choice for free grinding applications, especially for glass and jade products. Its versatility extends to delicate ceramic and precision workpiece grinding. It is a preferred abrasive for white, brown, and black corundum, as well as silicon carbide, iron sand, and copper ore.

Precision Grinding Tools: White and brown corundum are essential in the manufacture of resin grinding machines and coating grinding tools. These materials are crafted into high-quality sandpaper, sandwheels, and gauze, ensuring efficiency and robustness in abrasive tasks.

Rust-Free Sandblasting: Employ white corundum for sandblasting stainless steel, iron, and copper parts to achieve impeccable results. Its purifying action enhances deoxygenation and increases coating adhesion. It is also versatile for use in sandblasting plastics, glass, and even denim.

Superior Filler Material: While white corundum's premium price is notable, it stands as a top choice for flooring in factory sites, sports grounds, runways, and parking lots. However, more economical options like black and brown corundum are often used for abrasive flooring purposes.

Efficient Water Jet Cutting: White corundum is integral to water knife cutting, utilizing high-pressure hydraulic jets to efficiently cut through pipe and steel with precision.

Additional Applications for White Sand Include:
Exquisite Metalworking: White corundum sand excels in metal surface grinding and polishing. Its high hardness allows it to effectively remove oxide layers, rust, and stains, restoring a lustrous finish and brilliance to metal surfaces.

Precision Stone Cutting: Due to its exceptional hardness, white rigid jade sand is invaluable in stone cutting. It effortlessly completes tasks that standard grinding wheels cannot, ensuring smooth and precise stone cutting.

Enhancing Ceramic Manufacturing: In ceramics, white rigid jade sand acts as a superior abrasive, refining the surface finish and flatness of ceramic materials. It removes surface irregularities, resulting in smoother, more aesthetically pleasing ceramic products.

Electronics Excellence: Widely adopted in the electronics industry, white rigid jade sand is crucial in semiconductor processes. It polishes and levels thin films, removing surface defects, optimizing their optical and electrical properties.

Superior Glass Manufacturing: In glass production, white corundum sand is pivotal in polishing and repair, removing scratches and defects, and resulting in a smoother, clearer glass surface.
In summary, the exceptional physical and chemical properties of white corundum sand make it an indispensable asset across numerous industrial fields.
