Study on the Growth Model of Expandable Graphite

Abstract:

The expansion mechanism of expandable graphite (EG) was studied systematically in this paper. Based on the feature of the structure and the linear expansion of expandable graphite, a simple expansion model was established by the energy balance and mass balance equation. And the model was modified by setting of the boundary conditions. The result showed that a good agreement is confirmed by comparing the test data and model, especially the two inflection points of the growth rate. The study may provide theory support for improving using condition and expand application fields of the expandable graphite.
