Activated white bentonite clay is made of bentonite raw ore as raw material, It is an adsorbent by processing of  inorganic acidification treatment, water rinsing and drying, with an appearance of milky powder, smelly, tasteless, non-toxic, strong adsorption performance, it can absorb colored substances, organic substances. Easy absorption of moisture in the air, If placed too long or affected by moisture will reduce its adsorption performance, the use of appropriate heating (80-100 degrees is ok) , if heated to more than 300 degrees began to lose crystal water, its structure changes, affecting decolorization effect. Active clay is insoluble in water, organic solvents and various oils, almost completely soluble in hot caustic soda and hydrochloric acid, the relative density of 2.3~2.5, in water and oil swelled very little. Widely used in mineral oil, animal and plant grease, wax and organic liquid decolorization refining. It can also be used as desiccant for water, alkali antidotes for medicine, vitamin A, B sorbent, lubricating oil contact agent, gasoline gas phase preparation, etc. It can also be used as intermediate temperature polymerization catalyst, high temperature polymerization agent and raw material for the manufacture of granular clay.
