Activated alumina, also known as modern water activated bauxite, alumina(AL2O3) used in the catalyst is usually called activated alumina, it is a porous, highly dispersed solid material, it has a large surface area, microporous surface has catalytic properties, such as adsorption properties, fluoride removal properties, drying properties, surface activity, excellent thermal stability, etc. It is commonly used as a catalyst and catalyst carrier for chemical reactions.

1. Introduction of activated alumina balls

Name: Activated alumina ball

Appearance: snow-white spherical.

Use: Desiccant/adsorbent/defluorinator.

Composition: Al2O3AL

Content: 90%

High performance water activated alumina can bring the following advantages in the amorphous refractory: increase the density, fluidity, strength, secondary mullite generation, etc., reduce the amount of water added and porosity. Activated alumina can also be used as an adsorbent, desiccant, activated alumina ball water absorption, drying speed, renewable (400-500K baking), water absorption does not expand, no cracking, no deformation.

2. Activated alumina product appearance

Modern water activated alumina is a kind of white spherical porous particles with uniform particle size, smooth surface, high mechanical strength and strong hygroscopicity. After water absorption does not expand, does not crack, keep the original state, non-toxic, odorless, insoluble in water, ethanol, strong absorption of fluorine, can be used for the removal of fluoride drinking water in high fluoride areas.

3. The performance of activated alumina

Activated alumina can be selected to adsorb gas, water vapor and some liquid moisture. After adsorption saturation, it can be heated at about 175-315 ° C to remove water and restore regeneration. Adsorption and recovery can be performed multiple times. In addition to the desiccant, the steam of the lubricating oil can also be absorbed from the contaminated oxygen, hydrogen, carbon dioxide and natural gas. It can also be used as catalyst, catalyst carrier and chromatographic analysis carrier.

4. The use of activated alumina ball

It is widely used as a catalyst and catalyst carrier in the petrochemical and fertilizer industries. Modern water activated alumina has adsorption properties, used as gas-liquid desiccant, gas purification adsorbent, drinking water defluoridation agent, industrial sewage color and odor elimination agent.

5. Common specifications of activated alumina balls

1-3mm, 3-5mm, 4-6mm, 5-7mm, 6-8mm.

6. Packaging and storage methods of activated alumina balls

Plastic woven bag 25kg/50kg/ ton bag, the product should be stored in a dry place indoors. Do not open the package before use, so as not to absorb moisture and affect the use effect.
