The Research and Development of the Technology for Pressure Treatment of the Thermally Expanded Graphite Powders

Abstract

The paper presents the results of research of compactability processes of thermally expanded graphite powders during rolling. The thermally expanded graphite powders can be used to obtain highly porous and high-density products having different geometric parameters. The rolling method is used to produce long-length products. Strips production of the thermally expanded graphite with a particular thickness, density and physical-mechanical properties can be achieved by controlling the rolling conditions. When implementing the rolling process it is necessary to use plates due to high adhesion of powder to the rolls of the rolling mill. The usage of plates has allowed to develop the technology for the production of single and multilayer strips and evaluate its effectiveness.
