Brown aluminum oxidefine powder washing is a special process, suitable for customers who require low dust, low impurities and low carbon. Washing is to soak the brown fused alumina fine powder in water to filter out the dust and impurities in the fine powder.
Sometimes acid cleaning is also used to remove iron and carbon, so that the brown corundum will not detonate in use and increase toughness.
Brown aluminum oxide fine powder washing application fields:
1. Because the washed fine powder has the characteristics of high temperature resistance, corrosion resistance and high strength, it can melt precious metals and special alloys, ceramics and linings of ironmaking furnaces, physical and chemical containers, spark plugs, heat-resistant and anti-oxidation coatings. the
2. Due to its high hardness, good wear resistance and high strength, it can be used in various reaction vessels and pipes, chemical reactors for chemical pump components. Used to make knives, mold abrasives, bulletproof materials, human joints, etc. the
3. Corundum insulating materials, such as corundum lightweight bricks, corundum hollow balls and fiber products, are widely used in various high-temperature kiln walls and furnace roofs, all of which have high tolerance. It can be used for polishing, grinding, industrial grinding, etc. It can also be processed according to customer requirements, such as cleaning and pickling, to meet the different needs of customers.
Carry out pre-furnace treatment and special process treatment on low-carbon brown aluminum oxideto reduce the residual carbon content in brown fused alumina. High toughness is the material of choice for the abrasive industry and refractory industry. Mainly used for ceramic abrasives, high-grade abrasives, organic abrasives, abrasive belts, and coated abrasives. White corundum fine powder is harder and brittle than brown aluminum oxide.
According to the residual carbon content, the calcined brown aluminum oxide C is less than 0.05%, the low carbon brown corundum C is less than 0.10%, and the ordinary brown fused alumina C is less than 0.15%. Brown aluminum oxide abrasive is the best aggregate and filler for brown corundum refractories.
