What types of materials are prone to generating static electricity during transportation? Or is it that static electricity is generated whenever materials are transported?
Static electricity is very likely to be generated during the transportation of powdered materials, and this is quite dangerous. In the petrochemical industry, there are specific requirements regarding the grounding of such materials during transportation, and this is also a key aspect of safety inspections.
Theoretically, as long as it is an insulator and there is relative displacement, static electricity will be generated; only the degree and potential hazards vary
Oil is an insulating, non-polar substance with extremely low electrical conductivity. During the receipt, transfer, and filling of oils, static electricity is generated when the oil flows through pipes and comes into friction with the pipe walls, when it collides with the tanks and vessel walls during transportation, as well as due to the spraying and impact of the oil flow.
Organic solvents with generally low electrical conductivity tend to generate static electricity during storage, transportation, and delivery. Such as toluene, xylene, carbon tetrachloride, etc.
In that case, isn’t transporting polypropylene powder extremely dangerous?
Yes, solid materials and powders are prone to generating static electricity; liquids are relatively safer in this regard. I once saw at a site where powder was being transported that the pipes were glowing, and that was due to static electricity
Are all the pipes glowing? What’s going on?
