A: (1) static grounding. Grounding is the simplest and most basic method of eliminating static hazards. Mainly used to eliminate \x0d\\ conductive body on the static electricity, and should not be used to eliminate static electricity on the insulator. \x0d\ (2) humidification. Humidification is to increase the humidity of the air to eliminate the accumulation of static charges. There is a static danger of the field \x0d\ place, in the process conditions allow, you can install air-conditioning equipment, sprayers or use hanging wet cloth strips and other offices \x0d\ method, increase the relative humidity of the air. \x0d\(3) Add anti-static additives. Antistatic additives are specially formulated auxiliary \x0d\ agents. Generally only need to add a trace amount of thousandths of a see or ten thousandths of a see, can significantly eliminate static electricity in the production process. \x0d\ Phosphates, quaternary amine salts, etc. can be used as antistatic additives in the plastics and chemical fiber industries; oleates, naphthenates can be \x0d\ used as antistatic additives in the petroleum industry; acetylene carbon ink, etc. can be used as antistatic additives in the rubber industry and so on. \x0d\ Adoption of antistatic additives on, should not affect the performance of the product as a principle, should also pay attention to prevent some additives \x0d\ toxicity and corrosiveness. \x0d\ (4) electrostatic neutralizer. Electrostatic neutralizer is done with the help of electricity and ions. According to the working principle and \x0d\\ structure, can be broadly divided into inductive neutralizer, high-pressure neutralizer, radiation neutralizer and ion flow neutralizer. \x0d\ (5) process control method. Process control refers to the process to take appropriate measures to limit the generation and \x0d\ accumulation of static electricity. Process control methods are many, there are mainly the following: \x0d\ ① appropriate selection of better conductive materials; \x0d\ ② reduce the friction speed or flow rate; \x0d\ ③ change the way of oil injection (such as loading oil preferably from the bottom of the residence of the oil, or along the wall of the tank injected) and the shape of the injection pipe mouth; ④ installation of relaxation containers; \x0d\ ⑤ elimination of tanks or pipelines mixed impurities; \x0d\ ⑥ reduce the concentration of explosive mixtures. concentration of the explosive mixture.
