(Image) Diamond Sand
Diamond sand, also known as brown corundum, is a silicate mineral. Grinding materials are made through hydraulic separation, mechanical processing, screening, and grading. It has a long history of production and use. In ancient China, there were examples of using diamond sand to grind crystal glass and various jade stones. In the 1840s, it was also sold to the East. It can be divided into three categories: coarse, medium, and fine. The coarse grains are black red, the medium grains are light red, and the fine grains are red and white. The particle size and shape of each grain are uniform, and the edges are called angular crystals with sharp edges and high grinding force. Used for grinding soft materials such as marble in the stone industry. Grinding of glass burrs, television tubes, optical instruments, lenses, prisms, clock glass, and other metal industries for sandblasting, rust removal, and grinding. It can be used for grinding adhesive plates in the printing industry, as well as for light industrial processing such as plastic samples, leather, sandpaper, etc.
Low carbon diamond is processed before the furnace and treated with special techniques to reduce the residual carbon content in brown corundum, making the product non powdery, non explosive, and not easy to use. It is the preferred raw material for the abrasive and refractory materials industry. Mainly used for ceramic abrasives, high-end abrasives, organic abrasives, sand belts, coated abrasives, etc. According to the residual carbon content, it can be divided into calcined brown corundum C ≤ 0.05%, low-carbon brown corundum C ≤ 0.10%, and ordinary brown corundum C ≤ 0.15%.
One. Sandblasting - "Strong Gurley" silicon carbide has moderate hardness, high packing density, no free silicon dioxide, high specific gravity, and good toughness. It is an ideal "environmentally friendly" sandblasting material widely used in fields such as aluminum profiles, copper profiles, glass, precision molds, etc;
2. Free grinding - "Strong" grinding grade silicon carbide is widely used in fields such as cathode ray tubes, optical glass, monocrystalline silicon, lenses, clock glass, crystal glass, jade, etc;
Three. Resin abrasive "strong" silicon carbide has suitable color, good hardness and toughness, suitable particle cross-sectional type and edge retention, and can replace 20% -30% brown corundum as a filler for resin abrasive, with ideal effect;
Four. Coated grinding tools with "strong" silicon carbide are raw materials used in the production of zcbp, such as sandpaper, gauze, etc;
5 of them. Functional fillers - mainly used in automotive brake components, special tires, special construction products and other fields, can be used as wear-resistant materials for highway surfaces, airplane runways, docks, parking lots, industrial sites, sports fields and other buildings;
6. Filter material - strong diamond sand is a new application field. Using granular garnet as a filter bed substrate to purify drinking water or wastewater. It is a new type of water filtration material at home and abroad, especially suitable for non-ferrous metal beneficiation: petroleum drilling mud weighting agent:
Number 7. Water jet cutting is a new, environmentally friendly, and safe cutting method that uses diamond sand as the cutting medium and relies on high-pressure hydraulic jet for basic cutting. It is suitable for cutting components such as oil (natural gas) pipelines and steel.
[Sandblasting Diamond Sand]: Diamond sand sandblasting abrasive adopts modern and unique new technology, made of high-quality diamond sand. Diamond abrasive has the characteristics of short grinding time, high efficiency, high efficiency, and low price. This product has the advantages of moderate hardness, high toughness, good self sharpening, low sand consumption, recyclability, good grinding surface smoothness, stable chemical composition, wear resistance, acid and alkali resistance, etc. This abrasive has a shell shaped fracture surface with sharp edges, which can form new edges during continuous grinding and grading, making its grinding ability superior to other abrasives. Especially with advantages such as high hardness, high specific gravity, stable chemical properties, and unique self sharpening, it has become the preferred abrasive for sandblasting technology; Meanwhile, diamond sand is an ideal material for sandblasting, rust removal, cleaning workpieces, grinding and polishing.
