Prime activated alumina adsorption dryer dedicated activated alumina desiccant action: use unique microporous material itself to capillary action of water molecules adsorbed in the air, while relying on relief dryers adsorption-desorption temperature waste heat to take off the desiccant adsorbed moisture. Material: activated alumina, molecular sieves life: according to the humidity of the intake air is different, ranging from 2-6 years. Can be based on the dryer filter after the class to determine whether you need to replace the desiccant, if the filter drain, you need to immediately replace the desiccant, desiccant forms may also be based on the actual situation and the use of gas-side to judge. Extended use of hazard: desiccant loss of activity, can not be drained dry parts of active alumina, air moisture content exceeds the standard, the impact of the work with the production quality gas equipment and products; failure after dusting desiccant activated alumina adsorbents, affect the drying machine life, increased clogging of the exhaust pipe line resistance drop, increased power consumption and production costs activated alumina catalyst: in most cases, activated alumina powder, it is considered the catalyst itself and reactants join the chemical reaction, reducing the reaction activation energy required. Some catalytic reaction is readily decomposed due to the formation of "intermediate", the decomposition of the catalyst to restore its original chemical composition, the former becomes a product of reactants. Some catalytic reaction due to adsorption, adsorption only in the most active catalyst surface area (called the active center) is. The active center region of the greater or more, the stronger activity of the catalyst. If the impurity in the reactants, the catalyst activity may be reduced or lost, a phenomenon known as catalyst poisoning. Alumina, is ionic crystals, covalent bonding of hydrogen peroxide with activated alumina, a melting point of 2050 ℃, boiling point of 3000 ℃, true density of 3.6g / cm. It's good liquidity, insoluble in water, can be dissolved in the molten cryolite. It is an aluminum electrolytic production of major raw materials. There are four allotrope β- γ- alumina-alumina-alumina δ- α- alumina, the main type α and γ-type two variants, can be extracted from bauxite industry.
