Activated clay is a clay (mainly bentonite) as raw material, the inorganic acid treatment, and then rinsed by water, dry made of adsorbent, the appearance of milky white powder, odorless, tasteless, non-toxic, strong adsorption, adsorption Colored material, organic matter. Easy to absorb moisture in the air, placed too long will reduce the adsorption performance. However, heating to 300 degrees Celsius above began to lose crystal water, is the structure changes, affecting the fading effect. Advanced active clay products, products are gray, pink or white powder or granular, non-toxic and tasteless, insoluble in water, easy to absorb moisture; with a large surface area and more active acid center, which has a strong Of the adsorption and catalytic capacity, so not only have better decolorizing ability, while high activity, low oil consumption, faster filtration, is the ideal decolorization additives.
In the petroleum industry, for the petroleum resin, paraffin wax, paraffin oil, kerosene decolorization and purification; paper industry for copying paper stains, filling oil, dyes, the use of activated materials, The In the chemical industry as a catalyst for catalytic and catalytic carriers, insecticides, pesticides and fungicides, rubber and plastic fillers, desiccants and the use of desiccants for the use of fire extinguishers in forestry and soil and water conservation; Filter, radioactive waste adsorbent; in the water and sewage treatment for the absorbent and flocculant. When used to heat (to 80-100 degrees is appropriate) resurrection, if heated to more than 300 degrees began to lose crystal water, its structure changes, affecting the decolorization effect.
