Liaoning activated alumina ball catalyst carrier

Liaoning activated alumina ball catalyst carrier for centuries quality, sincere service, Ms. Kan: 13,521,797,362 010-57193076 ● not fail to find reasons to find a successful way ● ● unsuccessful people everywhere, but had a few successful people , the reason for their success, in addition to gifted, there are different from ordinary people's efforts and perseverance ● desiccant moisture, mildew, from the drying effect of the silica gel is a highly active adsorption material, usually with sodium silicate and response, and aging, acid bulbs and a series of post-processing in the system. Silica is amorphous material its chemical formula mSiO2. nH2O. Insoluble in water and any solvent, non-toxic, odorless, chemically stable, in addition to alkali, hydrofluoric acid does not react with any substance. The chemical composition and physical structure of the silica gel, determines that it has many other similar materials to replace the features: adsorption properties, good thermal stability, chemical stability, high mechanical strength. Also known as dehumidifiers agent. Adsorption or chemical absorption of water vapor solid materials. Vapor in the desiccant was removed by adsorption on silica gel, alumina gel, molecular sieve, activated carbon, bone charcoal, charcoal or attapulgite. Top desiccant to remove water vapor by chemical absorption method, calcium chloride, lime, or phosphorus pentoxide, and other substances with the chemical affinity of the steam. The desiccant is a moisture absorbed from the atmosphere in addition to a liquid, its drying principle is that the physical adsorption of water molecules in their structure or by chemical absorption of water molecules and change its chemical structure, it becomes another substances. Activated alumina adsorption capacity, large specific surface area, high strength, good thermal stability, can be widely used in chemical, petrochemical, natural gas and fertilizer industry as adsorbents, desiccants and catalyst. The activated alumina is a compound of aluminum and oxygen, MF as Al2O3. Also known as bauxite mining, ceramics and materials science. Emergency treatment, isolation leak contaminated areas, restricting access. Recommended emergency personnel wearing a dust mask (full cover), wear protective clothing. To avoid dust, carefully scan, bag placed transfer to a safe place. If large spills, using plastic sheeting, canvas cover. Recycling or collection shipped to the waste disposal sites. Preparation: intense heat of aluminum hydroxide, can be obtained amorphous white alumina powder. The use of activated alumina ruby, sapphire main ingredients are alumina, because other impurities present different color. Ruby red contains chromium oxide, the sapphire blue containing iron oxide and titanium oxide. In the principal component of the aluminum ore bauxite, alumina content of the highest. Industry, bauxite was purified via the Bayer Process alumina into aluminum metal, and then by the Hall-Heroult process. The alumina is aluminum metal in the air can not be easily cause corrosion. React with the oxygen in the pure aluminum metal easily with air to generate a thin layer of aluminum oxide film covering the surface exposed to the air in the aluminum. This layer of aluminum oxide film to prevent aluminum oxidation. This layer of oxide film thickness and properties can be accessed through a process called anodized (anodic corrosion) has been strengthened. 4 aluminum is a good conductor of electricity and heat. The aluminum crystal morphology Emery high hardness, suitable for use as abrasive and cutting tools.
