White aluminum oxide is widely used as abrasive and refractory materials, but there are many types of white aluminum oxide abrasives, and the quality is not the same. How to distinguish the quality of white aluminum oxide, how to choose the right white aluminum oxide?
The quality identification method of white aluminum oxide:
1. The main component of white aluminum oxide is AL2O3, which has good self-sharpening, good wear resistance, moderate hardness and good chemical stability. It is widely used in the fields of abrasives and refractory materials.
2. The alumina content determines the quality of white aluminum oxide. Generally, the higher the alumina content, the better the purity and quality of white aluminum oxide. When choosing white aluminum oxide, you need to know the purity of white aluminum oxide to ensure the quality.
3. Compared with brown aluminum oxide, white aluminum oxide is harder, and the hardness of white aluminum oxide also affects its quality, so when choosing white aluminum oxide, you must have a full understanding of the hardness of white aluminum oxide.
Uses of white aluminum oxide:
1. White aluminum oxide can be used as the basic material for abrasive sandblasting, which is due to its good corrosion resistance and wear resistance. Moreover, white aluminum oxide has moderate hardness and good self-sharpening property. As a sandblasting, white aluminum oxide does not affect the color of the workpiece and does not generate too much residue, so there is no need for cleaning. Whether it is metal or non-metal, it can be used for surface polishing, and it can also beautify the surface of jade and crystal.
2. White aluminum oxide abrasives can be used as raw materials for grinding wheels, sandpaper, abrasive belts and other abrasive tools to polish and grind objects. It can derust the metal surface, and can also process glass and acrylic materials.
3. White aluminum oxide is the raw material of refractory materials because of its good corrosion resistance and relatively stable chemical properties. Common white aluminum oxide refractory materials include high-temperature coatings, refractory bricks, furnace lining materials, etc.
