Which manufacturing industries have more serious electrostatic hazards
The following industries in the manufacturing industry are relatively high in electrostatic hazards: papermaking, textiles, printing, chemistry, chemicals, petrochemicals, rubber, plastic molding (coating), power electronics, and food.
1. Electrostatic hazards in the paper industry mostly occur during roller rewinding and product packaging, resulting in electric shock to personnel and product defects.
2. Electrostatic hazards in the textile industry are caused by the high-speed transmission of finished products and the accumulation of static electricity, which often leads to electric shocks and poor products. Fire and explosion accidents have also occurred because of this.
3. The types of static electricity hazards in the printing industry, plastics industry, and rubber industry are similar. Most of them occur in the high static electricity caused by the roll delivery of finished products, resulting in electric shock to personnel and poor products. Static electricity can also ignite fuel ink or solvents and cause fires. Explosion accident.
4. Electrostatic hazards in the petrochemical industry mostly occur in operations such as fluid transmission, mixing, powder grinding, feeding, and screening. Although the frequency of hazardous events is relatively low, if hazardous accidents occur, the consequences of the disaster are mostly serious.
5. Electrostatic hazards in the power electronics industry are mainly product defects and damage caused by static electricity. Electrostatic hazards in the food industry are mainly powder operations and alcohol tank storage and transportation operations.
To take preventive measures against electrostatic hazard accidents in the manufacturing process, one should first understand the principle of electrostatic hazard occurrence, be familiar with the factors of static electricity generation and dissipation in the process of hazard development, as well as the type and hazard of electrostatic discharge, and be able to identify each stage of electrostatic hazard formation, and then Able to use electrostatic measuring instruments to measure the substances and environment in the process, grasp the physical quantities of static electricity in the process, evaluate potential electrostatic hazard factors, follow up to develop and adopt appropriate electrostatic hazard prevention methods, and continue to measure Measurement and comparison of the effects of implementing electrostatic hazard protection measures can effectively reduce potential electrostatic hazards and improve operational safety and personnel safety in the production process.
