Carborundum is a high-hardness, high-toughness natural/man-made abrasive. Bairentong selects high-quality bauxite minerals as raw materials, refining them through multiple processes including crushing, magnetic separation, and sieving.
Made from natural carborundum minerals, the particles are rhomboid in shape, with sharp edges and corners, and possess high hardness.
Reddish-brown corundum, natural and environmentally friendly, low dust, reusable. Suitable for waterjet cutting and precision sandblasting.
Carborundum has a Mohs hardness of 7-9, with irregularly shaped angular particles, resulting in strong cutting force. During sandblasting, the high impact force and fast decontamination speed significantly improve work efficiency.
2. Good Self-Sharpening Properties, Reusable
Carborundum's unique shell-like fracture surface continuously generates new sharp edges during impact, maintaining continuous cutting ability. Carborundum can be reused more than 3 times, resulting in low overall operating costs.
3. Low Dust, Healthy and Environmentally Friendly
Bairtong carborundum undergoes multiple purification processes including dry cleaning, blowing, and magnetic separation, resulting in low dust generation. Compared to ordinary quartz sand, dust is reduced by more than 50%, eliminating the risk of free silica poisoning.
4. High cleanliness and excellent surface quality
After sandblasting, the workpiece surface cleanliness can reach Sa2.5-Sa3 level, with uniform and consistent roughness. The diamond abrasive particles can penetrate deep into holes and uneven areas, thoroughly removing rust, scale, soluble salts, and other contaminants.
Physical and Chemical Indicators
Main Application Areas
1. Sandblasting and Surface Treatment
Rust removal from steel structures, pipes, and ships
Deburring and removing weld slag from stainless steel/aluminum parts
Mold cleaning, pre-plating/pre-coating treatment
2. Wear-Resistant Flooring
Carborundum is the core aggregate for wear-resistant flooring. It is applied simultaneously with concrete to form a high-density, highly wear-resistant surface, suitable for:
Factory workshops, underground parking garages
Warehouses, docks, logistics centers
Repair workshops, warehouse-style shopping malls
3. Waterjet Cutting
Carborundum is the mainstream abrasive for waterjet cutting, offering fast cutting speed, smooth kerf, and high precision:
Stone and ceramic cutting
Precision cutting of metal sheets
Glass and semiconductor material cutting
4. Abrasives and Grinding Tools
Manufacturing grinding wheels, whetstones, abrasive cloth, sandpaper, grinding paste, etc.
