Investigation of the dependence of the specific electrical conductivity of low-concentrated water-coal suspension (WCS) from the concentration of the sodium humate reagent and from the concentration of the solid phase of suspensions

In this article is considered comprehensive research: 1) dependence of the specific electrical resistance of the WCS with an increase in the concentration of the sodium humate reagent-plasticizer at a constant solid phase of the WCS 2) dependence of specific electric resistance of WCS at increase in her firm phase without sodium humate reagent. At first sodium humate reagent with mass fractions from 10% up to 50% of the mass of firm phase WCS is added to WCS with concentration of firm phases of 10%, 30% and 50% and for each case, volt the ampere parameters are separately measured. Concentration of firm phases WCS remain constants, that is 10%, 30% and 50%. WCS in an experiment turns out under the influence of effect of hydrodynamic cavitation with concentration of 10%, 20%, 30, 40% and 50% of a firm phase. Use of hydrodynamic cavitation for receiving WCS the most effective, than influence electric and magnetic water as at cavitation of water there are reactionary capable radical particles •H and +•OH which in this case actively react with particles of a firm phase of carbon. Use of reagent-softener of a humate of sodium in this work is, explained by the fact that he renders the greatest effect on such physical properties of WCS as: viscosity, fluidity and stability. Except, that the humate of sodium is readily available and we accept from the economic party. Further the dependence of specific electric conductivity of WCS on concentration of a firm phase of suspension without sodium humate reagent-softener at increase in firm phase WCS from 10% to 50% is considered. The study found that: 1) with an increase in the concentration of sodium humates and with a constant solid phase of the WCS, the specific electrical conductivity, of the WCS increases, 2) when the solid phase of the WCS, is increased without the addition of reagents, the specific electrical conductivity of the WCS varies in a complex way: at first it remains constant, then gradually decreases and after a while again remains constant
