Product Description:
Brown corundum is a material that is created using high-quality bauxite as its raw material, along with anthracite and iron filings. The material is made via arc smelting at temperatures that are 2000°C or higher. The resulting material is crushed and plasticized with a self-grinding machine, magnetically selected to remove iron, and sieved into various sizes, forming a dense and hard texture. Spherical pellets of the abrasive are suitable for use in the production of ceramics, high-resistance abrasive resin, precision casting, grinding, polishing, sandblasting, and more. Additionally, brown corundum can be used to manufacture high-grade refractories.
Brown corundum abrasive has numerous unique characteristics, including high purity, good crystallization, strength in fluidity, a low coefficient of linear expansion, and corrosion resistance. Multiple fire-proof production companies have tested and verified that the use of brown corundum abrasive results in no explosion, chalking or cracking in the application process. Its cost-effectiveness is also much higher than that of traditional brown corundum, making it the best choice for fused alumina refractories.
Features:
Brown corundum is an effective and popular choice for sandblasting surface treatment, particularly for metal surfaces. This is due to several factors:
Less dust
Brown corundum has a relatively high density, which means that there is less dust produced during the sandblasting process. This is important for the health and safety of the operator, as well as improving visibility during the process. In contrast, other abrasives like slag and quartz sand are more brittle and thus easily break during the sandblasting process, causing environmental pollution.
High Efficiency
Brown corundum is a fast and effective method of spray grinding. Its small particle size allows for easy acceleration and high impact force on the surface of the object being treated. This results in a high cleaning rate that is usually twice as fast as other conventional abrasives.
The Environment
Brown corundum is a pure, non-toxic mineral without any harmful or toxic substances. It's a more environmentally friendly option as it produces less waste and can be recycled.
Recyclable
Brown corundum is recyclable and can be reused several times depending on its cutting ability. Once it's no longer effectively cutting surfaces, it can be used as a cement additive in the construction industry, making it a versatile and sustainable option.
