Hongda desiccant activated alumina

The products are white globular porosity particles with symmetrical particle size.
non-poisonous, no smell, odorless
Desiccant activated alumina
The products are white globular porosity particles with symmetrical particle size.

advantages:


(1). remain original shape when absorbing water
(2). non-poisonous, no smell, odorless
(3). insoluble to water and organic solvents.
In certain operating conditions, its dry-depth reaches below 70 degrees of dew-point temperature. It can be used as deacidificated regenerant of transformer oil and gas drying of oxygen industry, textile Industry and electronic industry, and air drying of automatic instrument and meter. It is also used as drying agent and cleaning agent in fertilizer and petrochemical industry (dew point reaches-40 degrees) and dew point reaches -55 degrees of pressure swing adsorption of space division industry. In one word, it is an efficient drying agent of deep drying in trace water.
