Studies on particle grade in the preparation of conductive composite bipolar plate;

Influence of particle grade on the electrical conductivity and gas-tightness of graphite/polymer composite;

Research progress on particle grade of conductivity polymer blending with the carbonic filler;

This paper has researched the effect of grain grading on expansive agent performance,the conclusion is:better performance of expansive agent can be achieved when the calcium sulfoaluminate,calcium aluminate clinker grain<45μm,anhydrite grain between 45μm～80μm.

Optimization of grain composition in the system of packing particle;

The relationship among the amplitude, the friction coefficient, grain composition and the porosity of block in different height is analyzed.

The grain composition in the system of packing particle plays an impor-tant role in the production of many products.

In this experiment,the different total salt level,different grain gradation artificial sample were compounded by use of the mixture of average design method to determine earth consistency limit.

Using a red volcanic ash taken from Jingyu County of Jilin Province as a raw material,samples with five different grain gradations are prepared.
