can be used to generate specific surface area (SSA) data, which is proportional to Blaine analysis data, under the condition of constant density.
These avoid the abrupt changes in particle-size distribution that occur between some neighbouring classes in the USDA diagram.
These do not accord with the relation between particle-size distribution and texture as perceived from the behaviour of the soil under manipulation in the field.
Also there are differences in the usage of the two systems on how to assess the texture when field description does not agree with particle-size distribution.
We also note that currently there are particle-size analysers used in Australian laboratories that can provide 10-15 size classes, which allows for a continuous particle-size distribution.
Buchan GD (1989) Applicability of the simple lognormal model to particle-size distribution in soils.
The normal N351 particle-size distribution is tight and homogeneous, whereas the skew of the hypothetical carbon black blends are exaggerated toward the particle size distribution of the two component grades.
The N110 component will be much more difficult to incorporate into the rubber matrix due to its significant smaller particle-size distribution.
Company customizes ultra-tight particle-size distributions down to submicron levels.
Controlled particle-size distributions and good particle integrity yield highly efficient flatting and anti-blocking agents for high-clarity films.
