Calcined Kaolin Clay for Coating
1, Introduction of the calcined kaolin
It is made from kaolin material, (Kaolin divided into from industry: Hard kaolin,Soft kaolin,Sandy clay), Calcined kaolin clay is calcined to a certain temperature
deep-processing products in the calciner,Calcined kaolin calcined during dehydration and the volatiles were removed, Fired at different temperatures with different physical properties of a calcined kaolin.
Size:20mesh,40mesh,60mesh,100mesh,200mesh,325mesh,800mesh,1250mesh etc.
Raw Material:High quality bentonite & concentrated sulfuric acid
Testing Method:According to HG/T2569-2007

4,Application of the calcined kaolin
♦Refinement of edible animal and vegetable oil:It can be used for decolorization and purification.Can remove harmful pigment,aflatoxin,phosphatide,saponin,colloid,cotton acid from oil to make it high-grade edible oil. |
♦Decolorization and refinement of edible animal and vegetable oil for industrial purpose. |
♦In petroleum industry,it’s used for decolorization,refinement,purification of minerals(such as diesel,kerosene,gasoline,grease,paraffin wax,white oil,lubricating oil,Vaseline,etc.). |
♦Recycling and regeneration of industrial waste oil(mineral oil like machine oil and lubricating oil). |
♦Decolorization and refinement of resin and natrum. |
♦Decolorization and refinement of polyether. |
♦In food industry,it’s used as clarificant for monosodium glutamate(MSG),vitamins,grape wine,sugar juice,also used in beer stability processing,saccharification processing,and sugar juice purification. |
♦Separation of olefin in arene and alkene,petroleum schizolysis,polymerization and catalysis of olefin. |
