Causes of static electricity in the storage of packaged goods

There are two main reasons for static electricity: One is the internal reason, that is, the electrical conductivity of the substance; the second is the external reason, that is, the mutual friction, rolling, and impact between the substances. Many commodity packages have internal conditions for static electricity generation. In addition, they are inseparable from handling, stacking, covering and other operations in storage, so friction, rolling, and impact will inevitably occur between packages. In the process of stacking, plastic packages of general commodities are prone to static electricity due to mutual friction.

The hazards of static electricity in the storage of packaged goods:

The accumulation of high electrostatic potential on the surface of the packaging is prone to static sparks. Its hazards are mainly manifested in two aspects:

One is to cause a deflagration accident. For example, when the contents of the package are flammable substances, their volatilized vapor and air reach a certain ratio, or when the solid dust reaches a certain concentration (ie, explosion limit), it will explode once it encounters electrostatic sparks.

The second is electric shock. For example, a high-potential discharge of static electricity is generated during the handling process, which will bring the discomfort of electric shock to the operator, which often occurs when the warehouse is handling plastic-packaged goods. In the process of handling and stacking, high-potential electrostatic discharge was generated due to strong friction, and even the phenomenon of operators being knocked down by electrostatic discharge occurred.
