Zhengda tells you: Activated alumina you don't know
Every kind of water purification material has hidden secrets that you don't know. Today, let's talk about the secret of the activated alumina ball that you don't know?
   The positively large activated alumina is an alumina having adsorption property, catalytic activity, high dispersion, and large specific surface area. It is suitable for drying various gases and liquids. It is used as adsorbent, desiccant, catalyst and carrier in many reaction processes such as petroleum and fertilizer, chemical industry. The activated alumina is classified into Y type and YP type according to the internal main crystal composition, and can be classified into an activated alumina adsorbent, an activated alumina desiccant and an activated alumina catalyst carrier according to the use thereof.
   Zhengda activated alumina spheres are widely used in the drying of various gases and liquids, and are used as adsorbents, desiccants, catalysts and carriers in many reaction processes such as petroleum, fertilizer, and chemical industry. Buy high-quality activated alumina, please look for the largest activated alumina plant in Henan Province.
   Zhengda activated alumina is a white globular substance, which is made by special process. Because of its unique skeleton structure, it has strong affinity with active components. The product has uniform pore distribution, suitable pore size, high pore volume and high bulk density. It has good mechanical properties and good stability. It is suitable for desiccant, catalyst carrier, FU agent, pressure swing adsorbent and hydrogen peroxide special regenerant. The CO-MO sulfur-tolerant shift catalyst prepared by using the product has the characteristics of good low temperature activity, wide temperature range and short curing time, and the catalyst is suitable for small and medium-sized synthetic ammonia plants.
   Activated alumina (molecular formula Al2O(3-x)(OH)2x, 0<x<0.8) is one of the most widely used inorganic chemical products in the world. Since activated alumina has a porous structure, a high specific surface area, and is in an unstable transition state, it has a large activity. In the petrochemical and fertilizer industries, it is widely used as a catalyst and catalyst carrier. Activated alumina has adsorption characteristics and is therefore used as a desiccant for gases and liquids, as an adsorbent for gas purification, as a dewatering agent for drinking water, as a color and odor eliminating agent for industrial sewage. The main industrial activated alumina products available today are produced by rapid dehydration. The activated alumina refers to calcined alumina which is sufficiently finely ground and has a basic composition of α-Al 2 O 3 having a primary crystal size of 1 μm as a basic composition (20% to 90%). Formula: Al2O3 ·nH2O (0
 　 The nano-alumina XZ-L14 of activated alumina showed a white fluffy powder state, and the crystal form was α-form. The particle size is 20 nm; the specific surface area is ≥ 50 m/g. Uniform particle size distribution, high purity, high dispersion, α-Al2O3, low specific surface, inert to high temperature, but not active alumina, almost no catalytic activity; strong heat resistance, good formability, stable crystal phase, High hardness, good dimensional stability, can be widely used in various plastics, rubber, ceramics, refractory materials and other products to strengthen and toughen, especially to improve the compactness, smoothness, thermal fatigue, fracture toughness, creep resistance of ceramics The wear resistance of variable properties and polymer materials is particularly significant. Since α-phase alumina is also a far-infrared emitting material with excellent performance, it is used as a far-infrared emitting and insulating material in chemical fiber products and high-pressure sodium lamps. In addition, α-phase alumina has high electrical resistivity and good insulation properties, and can be applied to main components of YGA laser crystals and integrated circuit substrates.
