The degree of this influence depends on dispersivity of particles and deficiency of their structure which is characterized by concentration of the active centers having the electric nature. Structure formation and hydration activity of disperse materials can be increased by high-voltage electric polarization. So, in an electric field with intensity of 1...5 kV/sm at the limited density of an electric current (up to 1мА/m2) there is a superficial and volumetric loading dispersions, easing ionic and bonds in connections that predetermines the activated condition of disperse particles.5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
