large surface area activated alumina
Fluoride agentactivated alumina:Molecular formula:Al2O3nH2O(n mino0 ,max0.8)
Molecular weigh: molecular weight min102 ,max117
Its physical and chemical property: white globular porosity particle, symmetry particle size,smooth surface,
huge machinery strength, strong hygroscopicity, after absorbing water it can keep original shape , non-poisonous, , no smell and insoluble to water and organic solvent.
The product obtained as a high fluoride water fluoride agent ,is a molecule with a huge surface area adsorbent.
When the original PH value and alkalinity of water is low, fluoride removal capacity higher than 3.0mg / g. It can
be used for eliminating fluoride, arsenic removal, wastewater decolorization, deodorization of drinking water
and industrial devices.Smaller particle size allows a larger surface area of the product.Generally 1-3mm, and water use have a greater contact area, surface area index of up to 26m2/g or more, a huge
number of pores can be guaranteed of fluoride in water has a strong adsorption capacity and high fluoride
capacity.
Activated alumina agent, home fluoride cylinder with built-AA-102 supporting the use of fluoride dose 1.6 kg, into the water out of the original, fluorine cylinder simple,
easy to use, ideal for the family drinking water fluoride removal deviceThe fluoride agents with the water
plant can also be industrial water fluoride removal device or devices supporting the use of fluoride.

Desiccant activated alumina
Its physical and chemical property: white globular porosity particle, symmetry particle size,smooth surface,
huge machinery strength, strong hygroscopicity, after absorbing water it can keep original shape , non-poisonous, , no smell and insoluble to water and organic solvent.
Under the definite operating conditions,the dry degree of this product can reach up to blew -70 degree of the dew-point temperature. It is mainly used as deacidification reclaiming agent of transformer oil; drying for gases in
industrial oxygen,textile industry and electron industry; dry the instrument and meter for automation, and
used as desiccant or scavenger in chemical fertilizer and petrochemical complex,which dew-point temperature can be -40 degree, or -55 degree in the space division industry. It is one kind of trace efficient desiccant.
