Properties: Activity white clay is a   fine,   grayish-white   powder   showing   a   highly   porous   inner   structure   & a   multitude   of Bronsted & lewis acid   sites   upon   its   surface. active   bleaching   earth has strong properties as cation exchange capacity, selective adsorption, hydrophilic property, surface activity and catalysis, It can
adsorbe and eliminate mineral materials as pitch, neutral colloid, sulfide and olefinenaphthenic acid in lubrication to improve the durability and photostability
of the lubricant and to increase the ability of corronsion-resisting, and can also absorb and eliminate the pigment, aflatoxin and the carcinogenic substance of 3-4 benzpyrene in vegetable oil,moreover, it has strong ability of oil decolorization, high speed of filtering oil and low oil retention of filter cake.

Functions:it's widely used in the absorption and refinement of lubricant, paraffin wax, and vaseline, the decolorization of Mineral oil and animal & vegetable oil, and the purification of honey, wax and glycerine
