Description
Alumina microbeads refer to high-performance inorganic materials with a diameter of micrometers. The main raw material is high-temperature calcined high-quality alumina powder, which is mainly made through mixing, crushing, grinding, molding, drying, sintering and other processes. According to the different alumina content, it can be divided into medium aluminum balls, medium-high aluminum balls and high aluminum balls. 92%,95% alumina belongs to high aluminum grinding balls. It is as hard as diamond, with a Mohs hardness is 9, dense structure, corrosion resistance, high temperature resistance, high wear resistance, high strength, high hardness, large specific gravity, small size and no pollution. It is widely used in various industries.
Advantages of High temperature resistant alumina microspheres
1. It has high thermal and chemical stability. Even when working in an acidic or alkaline environment, it can resist corrosion and wear, has good chemical inertness, and maintains durability.
2. It has extremely high hardness and wear resistance. Its hardness is higher than that of metal materials and other inorganic materials. It can effectively grind and grind materials of various hardness, improve grinding efficiency and precision, have low wear rate, less equipment wear, low maintenance cost, and reduce replacement frequency.
3. It has a large specific gravity and density. The specific gravity and density correspond to each other. Therefore, alumina microbeads with high specific gravity have a higher density, which greatly improves grinding efficiency and reduces grinding time. Therefore, it can provide greater grinding force and better grinding effect.
4. Alumina microbeads have environmental protection performance. The processing process of high-purity alumina materials has high purity, will not pollute the grinding materials, and meets environmental protection requirements.
