The Raw Material Used in The Production of Activated Alumina Ball Desiccant

Activated alumina ball particles are generally prepared with small particle diameter products of 1 ~ 3mm. The experimental results show that the smaller the particle size, the stronger the fluorine removal ability. When the pH value and alkalinity of raw water are low, the fluorine removal ability is greater than 3.0mg/g, the price is lower than synthetic resin, and can also be used to remove arsenic in drinking water.

The smaller the particle size, the larger the product surface area, generally 1 ~ 3mm, the larger the contact area of water, the surface index is greater than 160m2/g, the number of micropores, water fluoride removal ability is strong, high fluoride removal ability, activated alumina particles fluoride removal ability and anion exchange resin similar.

The raw material used in the production of activated alumina ball desiccant is industrial alumina hydroxide powder, which is a kind of non-toxic, odorless and non-corrosive common chemical material. After calcining at high temperatures, a large number of caviaries formed inside the sphere, using this property to absorb water and other substances.

In the production process did not add other undesirable substances, so the activated alumina ball desiccant is not toxic and corrosive, a small amount of ingested on the human body is not big. If accidental ingestion, it is recommended to accept the doctor's guidance immediately to the hospital.

Activated alumina ball desiccant is very widely used, can be used as a family desiccant, adsorption of water, in hydrogen peroxide aquatic production as a regenerative agent, in catalyst production as a carrier, in water treatment as a fluoride scavenger.
