rActivated alumina (Usage) High-performance activated alumina can bring the following benefits in amorphous refractory ingredients: increasing green body density, fluidity, strength, increasing secondary mullite production, reducing water addition and porosity.
In addition, activated alumina can also be used as a desiccant with high water absorption, fast drying speed and regeneration (400-500K baking).
R-activated alumina belongs to the category of chemical alumina. It is mainly used for adsorbents, water purifiers, catalysts and catalyst carriers. According to different uses, its raw materials and preparation methods are different.
R-activated alumina has many capillary channels and large surface area, which can be used as adsorbent, desiccant and catalyst. At the same time, according to the polarity of adsorbent, it has strong affinity for water, oxide, acetic acid, alkali and so on. Activated alumina is a kind of micro-water deep desiccant and also an adsorbent for polar molecules. Agent.
R-activated alumina is similar to anion exchange resin in fluoride removal, but it has large selective anion resin for fluoride ion. Activated alumina has good adsorption effect and stable capacity. It absorbs 6,400 grams of fluoride per cubic meter. Activated alumina has high strength, low wear, water immersion does not soften, does not expand, does not powder, does not break down. It is widely used in deep drying of petroleum cracking gas, ethylene and propylene gas, hydrogen production, air separation unit, instrument air dryer, fluoride treatment in hydrogen peroxide water. It can also remove sulfur, hydrogen dioxide, hydrogen fluoride, hydrocarbons and other pollutants in waste gas, especially for fluorine-containing water.
