The expansion parts and components of non-metallic in devices have become
a fait accompli. In the case parts, components of non-metallic are used in atmospheres
explosive and may be a potential source of ignition . Ignition hazards due to
static electricity from the charged non-conductive non-metallic materials are
well known . The prevalence protection metal parts and components of
anti-corrosion exist in any device equipped with a metal casing. Inherent risks
are caused by static electricity. Electrostatic
phenomena arise in many situations, in a variety of environments and
industries. The occurrence of charge static in many cases unexpected is unwanted and requires the use of expensive preventive measures. Brush discharge
and propagating brush discharge (e.g. composite coating about non-conductive
electrostatic properties of an isolated base conductive) create explosion
hazard in underground endangered by firedamp and/or coal dust .
