Method of manufacture of composites based on graphite expands active

摘要

Method of manufacture of composites having a base of expanded graphite, in particular for heat pumps chemical or for the treatment devices of the gases, comprising a stage of manufacture of a powder of expanded graphite, a step of pre - densification of this powder, a step of impregnation, preferably at atmospheric pressure, with a solution of reactive salt and a wetting agent, a step of drying and a step of densification. & br / the process according to the invention makes it possible to manufacture of a continuous manner and an active composite the performance characteristics of which are markedly improved with respect to the prior art.
