?
?
?
?
?
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

?
?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. |
