Abstract


The paper is devoted to the process of sintering-pressing of graphitoplast compositions. The phenomena occurring during the realization of this process are described: thermal desorption, immersion wetting, adhesive interaction of resin melt and graphite, combination of resin with hardener, polycondensation during resin solidification. Based on the results of the novolac resins solidification at the level of inventions, new methods for the manufacturing of powder products for electrical purposes have been developed. These methods were mastered in production conditions and passed certification tests that showed improvement of the mechanical and physical properties of products.
