Company a 24-hour service hotline :010 -56420693, 13810067470. The company's main Web site address: http://www.schb010.com/ adsorbent activated alumina factory, desiccant activated alumina prices - activated alumina adsorption properties, porous catalytic activity, high dispersion, Tabitha area alumina, suitable for a wide range of gas and liquid drying can be used for drinking water and industrial devices deaerator fluorine, arsenic removal wastewater decolorization. deodorant. Scientific deployment of high-purity alumina, catalytic finishing from it can absorb the removal of harmful fluoride. As an adsorbent, desiccant, catalyst and its carrier in petroleum, fertilizer and chemicals, food and many other reactions. Their use can be divided into: activated alumina sorbent, desiccant and catalyst carrier. The role of the active alumina balls: activated alumina ball suitable for the drying of a wide range of gas and liquid, In many during the reaction of the oil, fertilizer, chemicals, etc., as an adsorbent, desiccant, catalyst and its carrier. Activated alumina is a high dispersion of the solid material having a porous, with a large specific surface area, both good adsorption properties, and good pressure resistance, abrasion resistance and heat resistance, and therefore, is widely used as efficient adsorbent, desiccant, and the various reactions, the catalyst carrier. 1) Product grain structure, molecular formula, molecular weight, grain structure: XP-type formula: AL2O3 Weight: 102 2) the nature of the product: The product is white spherical porous substance non-toxic, odorless, not powder, insoluble in water. technical indicators name appearance Bulk density g / ml strength N / grain surface area m2 / g pore volume ml / g active% static adsorption capacity PH =% 60% water absorption% attrition rate indicators white spherical 127.4-392 300-340 0.38 0.65-0.8 -0.42 ≥ 70 16-18 50-75 0.1 activated alumina desiccant is used in the moisture, mildew, from the drying effect of silica is a highly active adsorbent material, and is usually a reaction of sodium silicate and sulfuric acid, and after aging , acid bulbs, such as a range of post-processing system. The Silicone case of amorphous material, its chemical formula mSiO2.nH2o. Insoluble in water and any solvent, non-toxic, tasteless, chemically stable, in addition to alkali, hydrofluoric acid does not react with any substance. The silicone chemical components and physical structure, it has many of the characteristics of other similar materials is difficult to replace: high adsorption properties, good thermal stability, chemical stability, high mechanical strength. Also known as dehumidifiers agent. Adsorption or chemical absorption of water vapor in the solid material. Desiccant of the water vapor is removed by adsorption with silica gel, alumina gel, zeolite, activated carbon, bone charcoal, charcoal or activated clay, etc.. Calcium chloride, quicklime or phosphorus pentoxide with the chemical affinity of the vapor of the material commonly used desiccant is removed by chemical absorption of water vapor. The desiccant is to absorb moisture from the atmosphere except a liquid, its drying principle is by physical means, the water molecules adsorbed on the own structure to absorb water molecules, or by chemical means and change its chemical structure, into another substances. Activated alumina adsorption capacity, large surface area, high strength, good thermal stability, can be widely used as adsorbent, desiccant and catalyst in the chemical, petrochemical, natural gas and fertilizer industries. Pure alumina is white, amorphous powder, commonly called alumina, density of 3.9-4.0g/cm3, m.p. 2050 ℃, boiling point of 2980 ° C, insoluble in water, the alumina mainly of α-type and γ-type two variants, industrial extracted from bauxite bauxite (Al2O3 · H2O and Al2O3 · 3H2O) is the main mineral of aluminum in nature, crushed impregnated with a high temperature sodium hydroxide solution, sodium aluminate solution; filtered to remove residue, and the filtrate was cooled and adding hydrogen alumina crystals, after prolonged stirring, the sodium aluminate solution may decompose the precipitated aluminum hydroxide precipitate; The precipitate was isolated washed, and then calcined at 950-1200 ° C the temperature of the, we obtain alpha alumina α-alumina powder, the mother liquor can be recycled by the Austrian scientist of Bayer (KJBayer) in 1888 invented today still is the main method for industrial production of alumina called "Bayer method". lattice, the oxygen ion is hexagonal close-packed, Al3 + are distributed symmetrically in the oxygen ion surrounded octahedral center, large lattice energy, melting point, boiling point, high α-type alumina is not soluble in water and an acid, industrial also known aluminoxane, is the system of the basic raw material of the metallic aluminum; also used various firebrick, refractory crucible refractory tube, high temperature experimental apparatus; abrasives, flame retardants, filler, etc. can be made; high The pure α-alumina or the production of artificial corundum, a raw material of synthetic ruby ??and sapphire; also for the production of modern plate base LSI. alumina is aluminum hydroxide obtained dehydrated under a low temperature environment in the 140-150 ℃ Industry also called activated alumina, aluminum and plastic. oxygen ions in its structure approximate heart closely packed cubic, Al3 + is irregularly distributed in the octahedral and tetrahedral voids surrounded by oxygen ions of the γ-type alumina insoluble can be dissolved in water, acid or alkali solution, it is heated to 1200 ℃ completely converted to α-alumina, γ-alumina is a porous material, the internal surface area of ??up to hundreds of square meters per gram, the active high adsorption ability. industrial often colorless or slightly pink cylindrical particles, pressure resistance is commonly used in the petroleum refining and petrochemical adsorbents, catalysts and catalyst carriers; transformer oil is industrially turbine oil deacidifying agent, also used in the color layer; in the laboratory is neutral strong desiccant drying capacity as much as phosphorus pentoxide, after use, following by heating at 175 ℃ also available in the regeneration of 6-8h repeated use. to account for more than 90% of total world production of alumina using the Bayer process, alumina system for aluminum, and less than 10% of the used for other purposes. |
