How to prevent static electricity in the storage and transportation of chemicals to ensure the safety of goods
There are two aspects of harm
1. Electric shock;
2. Causing combustion and explosion accidents;
Such as aluminum powder, when the aluminum powder dust in the air reaches a certain concentration, that is, the explosion limit, it will become an ignition source once encountering an electrostatic discharge spark, causing combustion and explosion.
It not only causes loss of goods, but also endangers life safety.
Causes of static electricity
The generation of static electricity has its internal and external causes.
The internal cause depends on the conductivity of the material,
The common external cause is the electrification caused by the mutual friction of substances. For example, friction, rolling, impact, etc. between materials during storage and transportation, followed by attached electrification, induced electrification, etc.
