Desiccant activated alumina are white globular porosity particles with symmetrical particle size,
They will remain original shape when absorbing water and they are non-poisonous,
no smell, odorless and insoluble to water and organic solvents.
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.
