METHOD ESTABLISHING COEFFICIENT OF SEPARATION OF SOLID PHASE BY LIQUID PHASE IN DISPERSED SYSTEM Russian patent published in 2003 - IPC

FIELD: testing and determining properties of materials, technology of building materials. SUBSTANCE: method establishing coefficient of separation of solid phase by liquid phase in dispersed system includes determination of density of liquid phase, density and volumetric mass of solid phase and calculation of coefficient of separation with due account of volume and mass characteristics. When N_l/s is greater than N coefficient of separation of solid phase by liquid phase is calculated by formula α = γ_s(N_l/s•ρ_s+ρ_l)/ρ_s•ρ_l, where α is coefficient of separation of solid phase by liquid phase in dispersed system, dimensionless value; γ_s is volumetric mass of dry solid phase, g/cu cm; ρ_s is density of solid phase, g/cu cm; ρ_l is density of liquid phase, g/cu cm; N_l/s is mass ratio of liquid and solid phases, dimensionless value; N = ρ_l(1/γ_s-1/ρ_s). EFFECT: reduced labor input to test of raw materials, increased accuracy of established value with allowance for greater number of characteristics of components of dispersed system, possibility of projection of compositions of compounds and building materials with utilization of given invention.
