This product uses high quality natural charcoal as raw material, according to different chemical production processes and different chemical properties of chemical products, it is refined by scientific methods. It is in the form of a black powder. It has the dual characteristics of physical adsorption and chemical adsorption. It can choose to adsorb large and small molecules in the liquid phase and gas phase to macromolecular pigments. It has wide adsorption performance and strong adsorption force. It does not release and dissolve in strong acid and alkali solution when saturated adsorption, and the filtration speed is fast. . Widely used in the production of chemical raw materials, chemical reagents, oily reagents, dye solvents and other decolorization and purification, deodorization and purification. It is also suitable for industrial waste gas recovery, air purification and soil improvement.
