Activated alumina is one of the inorganic chemical products widely used in the world. Because of its porous structure, high specific surface area and unstable transition state, it has great activity. It is widely used as catalyst and catalyst carrier in petrochemical and chemical fertilizer industries.
Activated alumina also has adsorption characteristics, so it can be used as desiccant for gas and liquid, adsorbent for gas purification, fluoride remover for drinking water, color and Odor Remover for industrial sewage, etc. Nowadays, the main industrial activated alumina products are produced by rapid dehydration.
It refers to fully fine grinding with the original crystal size of 1 μ M α- Al2O3 is calcined alumina with basic composition (20% - 90%). It has uniform particle size distribution, high purity, high dispersion α- Al2O3, which has low specific surface area and high temperature resistant inertia, does not belong to activated alumina and has little catalytic activity.
It has strong heat resistance, good formability, stable crystal phase, high hardness and good dimensional stability. It can be widely used to strengthen and toughen all kinds of plastics, rubber, ceramics, refractories and other products, especially to improve the compactness, smoothness, cold and hot fatigue, fracture toughness, creep resistance and wear resistance of polymer products.
because α Phase alumina is also a far-infrared emission material with excellent performance. As far-infrared emission and thermal insulation material, it is used in chemical fiber products and high-pressure sodium lamps. In addition, α Phase alumina has high resistivity and good insulation performance. It can be used in the main accessories of YGA laser crystal and integrated circuit substrate.
The appearance of activated alumina filter material is white spherical, which is made by special process. Due to its unique skeleton structure, it has strong affinity with active components. The activated alumina ball has uniform micropore distribution, appropriate pore size, large pore volume, high water absorption, small bulk density, good mechanical performance and good stability. It is suitable for desiccant, catalyst carrier, fluoride removal agent Pressure swing adsorbent.
The Co-Mo sulfur resistant shift catalyst prepared with this product has the characteristics of good low-temperature activity, wide operating temperature range and short vulcanization time. The catalyst is suitable for small and medium-sized ammonia plants.
