Which manufacturing industries have more serious electrostatic hazards?
The following industries in the manufacturing industry are highly hazardous to static electricity: papermaking, textiles, printing, chemistry, chemicals, petrochemicals, rubber, plastic molding (coating), power electronics, and food.
1. The static electricity hazards in the papermaking industry mostly occur during roll rewinding and product packaging, causing electric shocks and product defects.
2. The static electricity hazard in the textile industry is often caused by high-speed transmission of finished products and accumulated static electricity, which causes electric shocks and poor products. Fire and explosion accidents have also occurred.
3. The types of electrostatic hazards in the printing, plastics, and rubber industries are the same. High static electricity caused by the finished product coiling operation often causes electric shocks and poor products. Static electricity can also cause fuel ink or solvents to cause fires. Explosion accident.
4. Electrostatic hazards in the petrochemical industry mostly occur in operations such as fluid transfer, mixing, powder grinding, feeding, and screening. Although the frequency of hazardous events is low, if a hazardous accident occurs, the consequences of the disaster are mostly serious.
5. The electrostatic hazards of the power electronics industry are mainly caused by static electricity to cause product defects and damage, and the electrostatic hazards of the food industry are mainly caused by powder operations and alcohol tank storage and transportation operations.
To take preventive measures against electrostatic hazard accidents in the manufacturing process, you should first understand the principles of electrostatic hazards, familiarize yourself with the factors that generate and dissipate static electricity in the development process of the hazards, as well as the types and hazards of electrostatic discharge, and be able to identify each stage of the formation of electrostatic hazards. Be able to use electrostatic measuring instruments for the causes of the hazards to measure the substances in the process and the environment, grasp the physical quantities of static electricity in the process, evaluate the potential electrostatic hazards, and follow-up to develop and adopt appropriate methods to prevent electrostatic hazards, while continuing to measure Measure and compare the effect of implementing electrostatic protection measures, which can effectively reduce potential electrostatic hazards and improve the safety of operations and personnel in the production process.
