Description
technical field [0001] The invention relates to the technical field of electrostatic charge measurement, in particular to an automatic chute frictional charge test device for energetic materials. Background technique [0002] Energetic materials are mostly high-insulation substances. When the particles and equipment or particles rub against each other, a large amount of static charge will be generated, and electrostatic discharge is very easy to cause combustion and explosion accidents, causing heavy casualties and property losses. According to statistics, about 10%-20% of accidental explosion accidents of energetic materials are caused by electrostatic discharge. In order to study the electrostatic properties of energetic materials and take targeted control measures, it is necessary to study their electrostatic electrification laws. The means to study the law of electrostatic electrification is to test the electrostatic charge of the material, mainly using the way of chute...
