  The
characteristic and use of Activated bleaching earth:
Characteristic: covered taking off stone 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.
Use: The main use of Activated bleaching earth has three
respects:
Petrochemical industry: make incomplete carbon value
, gray 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, 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 .
