Abstract
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 [1]. Ignition hazards due to static electricity from the charged non-conductive non-metallic materials are well known [2]. The prevalence protection metal parts and components of anti-corrosion exist in any device equipped with a metal casing. Inherent risks associated services 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 [3].
Highlights
The prevalence of static electricity and related phenomena makes that the general principles selection of a material non-metallic should be based on the value parameters of resistance and the value of a designated charge transfer from the charged material non-metallic
To study the electrostatic properties of selected natural and synthetic materials non-metallic and non-metallic products obtained from the processing of synthetic nonmetallic materials, which are widely used in underground mining [10]
Audited types of a materials non-metallic are the properties of electricity a nonconductive, which in the conditions of use can accumulate charge induced
Summary
Charging is the primary source of excitation causing of electrostatic charge on the surface material non-metallic [13]. To determine the effectiveness of “chargeability”, for all types charging used the other samples of material non-metallic [14]. On the neutral material non-metallic density of a charges induced related is equals zero
