Static Eliminator in the plastic industry electrostatic application
In many processes in the plastics industry, the classic hazards are very large, lightly affecting the quality of the product, but may lead to fires and explosions. In the working environment, all fire and explosion events caused by static electricity follow the same procedure, as follows The first: the charge separation occurs first, and then the charge is accumulated. If the charge cannot be dissipated, an electrostatic discharge will occur, and at the same time, the surrounding flammable substance may be ignited, and a fire and explosion hazard event may occur.
The electrostatic hazard prevention method can be divided into five types: grounding, increasing humidity, limiting speed, antistatic materials, and static eliminator. In the industrial manufacturing process, the electrostatic hazard prevention methods implemented will vary depending on the operating environment, procedures, and materials. When selecting, we must consider the on-site process environment, conditions and restrictions, and even the factors such as funding, management system and human quality. There is no electrostatic hazard control method that can be applied to all industrial processes or situations, sometimes using two or more electrostatic hazard control methods.
Most industrial processes may generate static charge accumulation, which may make people feel uncomfortable, and may cause harm to the human body and even cause fire and explosion accidents. These electrostatic hazard accidents must have the following development process: firstly, static electricity is generated by friction, induction or conduction, and then charges of different polarities accumulate on the equipment, the human body or the product, and the electric charge is accumulated enough to cause The discharge phenomenon, and the energy released by the electrostatic discharge is enough to ignite the surrounding flammable substances, it will cause a fire or explosion disaster. Clearly understand each stage of the formation of electrostatic hazards, help identify the causes of electrostatic hazards, and develop appropriate countermeasures, improve the safety of the process site and operators, and effectively reduce static hazards and production losses.
