If there is no activated alumina ball, what should I do if it is dry?
Through social investigation and experiments, we have proved that activated alumina spheres have many capillary channels, large surface area, and the surface micropores have the characteristics required for catalysis. The adsorption defluorination effect is very good, the capacity is stable, and each cubic meter of activated alumina is sucked. Fluorine is 6400 grams and is therefore widely used as a catalyst for chemical reactions and as a catalyst carrier. The high-performance activated alumina can bring the following advantages in the composition of the amorphous refractory: increase the density, fluidity, strength, increase the amount of secondary mullite, and reduce the water addition and porosity. In addition, activated alumina can also be used as a desiccant, with large water absorption, fast drying speed and regenerative (400-500K baking).
The above is said to describe the role of activated alumina balls from a more professional point of view, so which form does it exist? This is to say the appearance of the activated alumina ball. It is not difficult to see from its name. It is a spherical object. The diameter of its spherical body is most commonly 3-5mm. Of course, it is still larger. For example, 4-6mm, 6-8mm, but also a smaller 1-2mm, its specifications can be produced according to customer needs. Its color is white, the micropores on the spherical surface are used for adsorption, and it has strong hygroscopicity. It does not swell and remain intact after water absorption. It is non-toxic, odorless and insoluble in water and ethanol. It has strong adsorption to fluorine.
