The characteristic and use of Activated bleaching earth: Characteristic: covered taking off montmorillonite after the acid is activated and dealt with and exchangeability ion (calcium , magnesium , potassium , sodium ,etc. ) are replaced and dissolved out by the little diameter ion , make both ends of the narrow passage of crystal increase and the surface area increase. Meanwhile, because hydrogen ion replacing octahedra or tetrahedron many price ion, have caused the electricity to shoulder even more. Make acid activate stone turn into strong active white soil with strong absorbing and discoloring ability . Uses: Oil industry--- Lubricating oil, gear oil, gear oil transformers, waste oil, diesel oil etc.make incomplete carbon value , gray, pink powder , water soluble sour alkali of lubricating oil reduce to the utmost point, in order to improve its durability and strengthen its anticorrosive ability. Edible oil trade--- salad oil, soybean oil, rapeseed oil, palm oil, etc. it is used to get rid of different pigment, take off the strange smell , break away from the son (such as K+); absorb , separation of harmful substance such as aflatoxins etc. Daily-use chemical industry trade---is mainly used for discoloring ox, sheep oil which can make the products, such as soap, etc. In order to meet various kinds of special requirements of the customers, this product can be adjusted on the basis of the above specification: (1)Change the strength of discoloring, adapt to requiring with discoloring. (2)Change each and is distributed, meet the new-type craft of filtering. (3)Reduce hydrogen ion index, increase the acidity, raise and take off the chlorophyll result. (4)Reduce free acid and hydrogen ion catalysis activation degree, cooperate with the neutral oil to deal with. (5)Improve activation degree of the hydrogen and ion , is used as the catalyst .
