Alumina powder is the main component of brown corundum and white corundum sand. It is white powder, containing Al2O3>98% and melting point>2000℃. It is also the main raw material for electrolytic aluminum, chromium corundum and neodymium praseodymium corundum. Its quality determines the quality of corundum abrasive to a large extent. Not only that, high-temperature calcined alumina powder has a wide range of uses, and it is indispensable in many processes. From alumina to alumina powder, it needs to be processed through multiple processes. Perfect molding, that is to say, the quality of alumina powder directly depends on the raw materials, processing procedures, etc. So how to control the production process to produce high-quality alumina powder?

Alumina powder production line
1. Nano-alumina transparent liquid XZ-LY101 has high hardness and good dimensional stability. It can be widely used in the reinforcement and toughness of various plastics, rubbers, ceramics, refractory materials and other products.
2. Nano alumina transparent liquid is transparent and high in content. No precipitation or stratification.
3. Nano alumina transparent liquid PH=7.0, but the specific pH value can be adjusted according to customer requirements. Adjusting the ph value has no effect on the liquid.
4. Nano-alumina transparent liquids include water-based liquids, oily liquids, and can be alcohols, ethers, and ketones. All are transparent and have good compatibility.
5. Nano-alumina transparent liquid improves the compactness, smoothness, thermal fatigue, fracture toughness, creep resistance and wear resistance of polymer material products, especially alumina powder.
6. Nano-alumina transparent liquid is a far-infrared emitting material with excellent performance. It is used as a far-infrared emitting and thermal insulation material in chemical fiber products and high pressure sodium lamps. In addition, alumina has high resistivity and good insulation properties, which can be used in the main parts of YGA laser crystals and integrated circuit substrates.
7. Improve the scratch resistance and durability of UV-curable coatings. These UV-curable coatings are widely used in areas that require high wear resistance, such as plastic floor nano-alumina XZ-L690 in white and fluffy powder state, and the crystal form is γ- Al2O3. The particle size is 20nm; the specific surface area is ≥160m2/g. Uniform particle size distribution, high purity, excellent dispersion, high specific surface, high temperature resistant inertness, high activity, belonging to activated alumina; porosity; high hardness, good dimensional stability, strong surface acidity and certain The surface is basic and is widely used as new green chemical materials such as catalysts and catalyst carriers.
