Application and prospect of activated clay

Activated clay is an adsorbent made of clay (mainly bentonite) as raw material,treated by inorganic acidification,rinsed with water,and dried. The appearance is milky white powder,odorless,tasteless, non-toxic, strong adsorption, and can be adsorbed, colored substances and organic substances.It is easy to absorb moisture in the air,and it will reduce the adsorption performance if it is placed for too long. However, when heated to above 300 cent degrees,it begins to lose crystal water, which is a change in structure and affects the fading effect.The activated clay is insoluble in water, organic solvents and various oils, and is almost completely soluble in hot caustic soda and hydrochloric acid.The relative density is 2.3 to 2.5, and the swelling in water and oil is extremely small, which is widely used in the decolorization and purification of mineral oil, animal and vegetable oils,wax and organic liquids.It can also be used as a water desiccant, internal medicine anti-alloy,vitamin A,B adsorbent,lubricating oil superposition contact agent,gasoline gas phase refined preparation, etc. It can also be used as medium temperature polymerization catalyst, high temperature polymerization agent and raw material for producing granular clay.

Application range

Activated clay has large specific surface area,strong adsorption capacity and high decolorization efficiency;It has low activity,and there is no chemical interaction with oils and other chemicals;It is used for liquid decolorization and filtration with low residual liquid rate,such as edible oil decolorization,sugar production decolorization,etc.;The liquid is transparent and clear after decolorization, and the quality is stable,There is no odor,no color change and no acid return;the product after use can be used for secondary use after proper treatment,and will not be caused by environmental pollution. It is widely used in the developer of adsorbent,granular clay and carbonless copy paper.
