Grinding Excellence: White corundum is prominently utilized in free grinding operations for materials like glass and jade products. Its versatility extends to ceramic and precision workpiece grinding, where it shares the stage with brown corundum, black corundum, silicon carbide, iron sand, and copper ore, offering superior abrasive performance.
Grinding Tools Innovation: White and brown corundum are pivotal in manufacturing resin grinding machines and coated grinding tools. These materials contribute to the production of high-quality sandpaper, sandwheel, gauze, and more, enhancing the efficiency and effectiveness of abrasive tools.
Sandblasting and Rust Removal: White corundum is ideal for sandblasting stainless steel, iron parts, and copper workpieces. Its abrasive properties enable the purification, deoxygenation of surfaces, and improved coating adhesion, making it suitable for plastic, glass products, and denim sandblasting operations.
Filler Versatility: Predominantly used in flooring materials for factories, sports grounds, runways, and parking lots. While white corundum is premium-priced, black and lower-grade brown corundum are often chosen for abrasive floor applications due to cost-effectiveness.
Water Jet Cutting Mastery: Leveraging high-pressure hydraulic jets, white rigid jade sand excels in precise cutting applications for pipes and steel, providing a seamless cutting experience.
Additional Remarkable Uses of White Sand Include:
Metalworking Precision: With outstanding hardness, white corundum sand excels in grinding and polishing metal surfaces. It efficiently removes oxide layers, rust, and stains, restoring shine and brilliance to metal surfaces.
Stone Cutting Superiority: In stone cutting, white rigid jade sand stands out. Its high hardness makes it an excellent choice for cutting tools, enabling easy and efficient stone cutting.
Ceramic Finish Excellence: During ceramic manufacturing, white rigid jade sand serves as an abrasive, significantly enhancing surface finish and flatness, ensuring ceramic products achieve superior quality and aesthetics.
Electronics Industry Application: In semiconductor manufacturing, white rigid jade sand plays a crucial role in polishing and leveling thin films, enhancing optical and electrical properties by removing surface inhomogeneities and defects.
Glass Manufacturing Perfection: White corundum sand is integral in the glass manufacturing process. It adeptly polishes and repairs surfaces, eliminating scratches and defects, thus achieving a smoother, more transparent glass surface.
In Conclusion: White corundum sand stands out for its unique physical and chemical properties, making it indispensable across numerous industrial fields.
