4)Usage and application scope:
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. |
5)Storage of Products:Shall be stored in a ventilated and dry place.During transportation process,clean vehicles should be selected,intense vibration should be prevented as much as possible,loading and unloading shall be handled with care to avoid damage of packing bags.In addition,moisture and rain should be avoided.
