With the wide use of tons of bags, problems also follow, such as static electricity, next Xiaobian to talk to you about the causes of static electricity ton bags and prevention methods.
1. Causes of static electricity in tons of bags:
One is the internal reason, that is, the conductivity of the material; The second is external causes, namely friction, rolling and impact between materials. Many commercial bags have internal conditions for generating static electricity. In addition, in the storage process, handling, stacking, covering and other operations are also essential. Therefore, friction, rolling, impact and other phenomena will inevitably occur between tons of bags. The plastic packaging of general goods is easy to generate static electricity due to mutual friction during the stacking process.
The electrostatic hazards generated during the storage process of the ton bag accumulate on the surface of the ton bag, forming a high electrostatic potential, which is easy to produce electrostatic sparks. Its harm is mainly manifested in two aspects: first, it causes deflagration accidents. For example, the contents of the package are flammable substances that volatilize steam and air to a certain proportion, or solid dust reaches a certain concentration (i.e. the explosion limit) and will explode once it encounters an electrostatic spark. Second, the phenomenon of electric shock. For example, during the handling process, electrostatic high potential discharge will bring electric shock discomfort to the operator, which often occurs in the warehouse when handling plastic packaging goods. In the process of handling and stacking, due to the large friction, electrostatic high potential discharge is generated, and even electrostatic discharge knocks down the operator.

Second, the method of preventing static electricity
The following methods are generally used to prevent and control the harm of electrostatic hazards in tonnage bags:
1, ton bag should avoid static electricity as much as possible. For example, when dealing with flammable liquid, it is necessary to limit its violent shaking in the packaging barrel, control its treatment method, prevent the leakage of different oils, mix, and prevent water and air intake in the steel barrel.
2. Take measures to dissipate the generated static electricity as soon as possible to avoid accumulation. For example, good grounding devices are installed on tools such as handling, increasing the relative humidity of the workplace, laying conductive floors on the ground, and spraying conductive coatings on some tools.
3, add a certain amount of anti-charge in the charged body to avoid the increase of electrostatic voltage (such as induction electrostatic neutralizer).
4, in some cases, the accumulation of static electricity is inevitable, the rapid rise of electrostatic voltage may even produce electrostatic sparks. At this time, even if the discharge occurs, measures should be taken to prevent the occurrence of explosive accidents. For example, inert gases are injected into the storage space of flammable liquids, alarm devices are installed, and exhaust devices are used to reach the explosive limit of flammable gases or dust in the air.
5, in places with fire and explosion hazards, such as chemical dangerous goods storage places, staff wear conductive shoes, wear electrostatic work clothes, etc., timely eliminate the static electricity carried by the human body.
