(54) СПОСОБ ОПРЕДЕЛЕНИЯ ГРАНУЛОМЕТРИЧЕСКОГО СОСТАВА(54) METHOD FOR DETERMINING GRANULOMETRIC COMPOSITION

Claims (1)

Формула изобретенияClaim Способ определении гранулометрического состава, например удобрений, заключающийся в рассеве отобранной пробы на фракции по размерам и нахождении доли каждой фракции в отобранной пробе, отличающийся тем, что, с целью ускорения и повышения надежности определения, после рассева каждую фракцию пробы последовательно растворяют в одном и том же объеме растворителя, измеряют электропроводность получаемых при этом растворов, а долю каждой фракции определяют по соотношению прироста электропроводности при растворении каждой фракции к величине электропроводности раствора отобранной пробы.A method for determining the particle size distribution, for example, fertilizers, consisting in sieving the selected sample into fractions by size and finding the fraction of each fraction in the selected sample, characterized in that, in order to accelerate and increase the reliability of determination, after sieving, each sample fraction is successively dissolved in the same volume the same volume of solvent, the electrical conductivity of the solutions obtained is measured, and the fraction of each fraction is determined by the ratio of the increase in electrical conductivity upon dissolution of each fraction to the values solution conductivity of the sample taken.
