Dust-free corundum, this product is made from brown corundum micro-powder through pressure extrusion and sintered into shape at 2200 degrees Celsius. It has moderate hardness, is clean and tidy, not easy to break, and can be used repeatedly multiple times. The sandblasting effect is excellent.

1. Glass sandblasting, surface matte finishing for steel, steel pipes, steel structures, and stainless steel products. Rust removal by sandblasting before painting.

2. Cleaning for various molds

3. Removes stress in various machine parts, enhancing fatigue life

4. Cleaning and de-burring prior to soldering on plastic encapsulated dual in-line package (DIP) semiconductor devices

5. Shot Peening and Surface Finishing Services for Textile Machinery and Various Hardware Products

6. Cleaning and deburring of various metal tubes and non-ferrous metal castings.

Product Features of Dust-Free Silicon Carbide:

1. Versatile in Hardness and Flexibility—Manufactured with high-quality materials, offering both mechanical strength and sufficient elasticity. The AL2O3 content is greater than or equal to 68%, with a hardness of 6-7 Mohs. It can be used repeatedly without breaking, and the sprayed parts maintain consistent performance, boasting a lifespan 3 times longer than that of regular corundum.

2. Good uniformity – roundness greater than or equal to 80%, particle size uniform, post-spraying ensures even brightness coefficient across the sandblasting device, leaving no watermarks easily.

Dust-free silicon carbide is a silicate mineral primarily composed of silicon dioxide, which undergoes hydraulic classification and mud removal to achieve a reasonable particle size ratio.

Dust-free corundum sand boasts numerous advantages, including low density, excellent thermal insulation, excellent impermeability, superior alkali aggregate reactivity, low water absorption rate, good frost resistance, and excellent durability.

Dust-free Silicon Carbide, also known as washed sand, as the name implies, its main feature during use is dust-free. Its composition allows it to be a highly durable abrasive material that is reusable.

The abrasive treatment is effective and efficient. Dust-free silicon carbide is used in glass manufacturing plants to grind glass products such as microscope lenses, petri dishes, glass containers, etc., achieving the required smoothness on their surfaces.

Also used in shipyards, steel structure factories, tool manufacturers, flooring construction, automotive manufacturing, and waterjet cutting industries.
