Bright prospect of application of activated white clay
China's oil network reported (correspondent peak): activated white clayis clay (mostly bentonite) as raw materials, with inorganic acidtreatment, and then rinse with water, dry sorbent made from, theappearance of milky white powder, odorless, tasteless, non-toxic,strong adsorption properties, absorb colored material, organicmaterial. Easy to absorb moisture in the air, place too long can reduceabsorption properties. However, the above began to lose crystal waterheated to 300 degrees Celsius, so that changes in the structure,affecting the fade effect. Activated white clay is insoluble in waterand organic solvents and oils, almost completely soluble in hot sodium hydroxide and hydrochloric acid, relative density at 2. 3~2. 5,bentonite in water and oil are very slight. Widely used in mineral oil,animal and vegetable fats, waxes and bleaching refining of organicliquids. Can also be used as desiccant moisture, alkali antidotemedicines made up ready, adsorbents for vitamins a, b, and coincidentexposure to agents of lubricating oil, petrol refining agent vapor,temperature is also used as a polymerization catalyst, and manufactureof high temperature polymerization agent particulate clay raw material.
