20. The static electricity generated during the manufacturing process poses various dangers, and effective technical and managerial measures must be taken in combination to prevent it. Among the following measures for preventing static electricity hazards, the incorrect one is ( ). P102 A. Reduce the process speed B. Increase relative humidity C. Directly ground the high-insulation material D. Use antistatic additives C 【Explanation】: The main measures for preventing static electricity include: (1) Controlling the level of hazard in the environment. Such as replacing flammable media, reducing the concentration of explosive gases and vapor mixtures, and decreasing the amount of oxidizers. (2) Process control. Such as using metallic materials, restricting the movement speed of the material, and accelerating the static electricity dissipation process. (3) Static grounding. (4) Humidification. (5) Antistatic additives. (6) Electrostatic neutralizer. (7) Static protection clothing.
The static electricity generated during chemical production poses various dangers, and effective technical and management measures that are combined with each other must be taken to prevent it. Among the following measures for preventing static electricity hazards, the incorrect one is (A).
C-----------------------------------------------------------------
The answer is C: high-insulation direct grounding.
The static electricity generated during chemical production poses various dangers, and effective technical and management measures that are combined with each other must be taken to prevent it. Among the following measures for preventing static electricity hazards, the incorrect one is (c). High-insulation devices are directly grounded, making it impossible to discharge static electricity
