The main preventive measures for wrist strap monitors against electrostatic hazards include reducing the generation of static electricity, trying to conduct or dissipate static electricity, and preventing static electricity discharge. The specific method to be used should be selected after comprehensive consideration based on the characteristics and conditions of the production process.
1. Static electricity neutralization: Static electricity on insulators cannot be eliminated by grounding, but it can be neutralized by using charges of opposite polarity. The current method of "neutralizing static electricity" is to use static electricity control equipment. Its function is to use air ionization to generate a large number of positive and negative charges, forming a positive and negative charge airflow to neutralize the charge on the object. When the surface of the object is negatively charged, it will attract the positive charge in the airflow, and when the surface of the object is positively charged, it will attract the negative charge in the airflow, so that the static electricity on the surface of the object is neutralized, achieving the purpose of eliminating static electricity.
2. Grounding: Grounding is the simplest and most basic way to eliminate static electricity. It can quickly conduct away static electricity. But pay attention to the grounding wire of the static electricity-carrying object, which must be firmly connected.
3. Prevent the human body from carrying static electricity: When people walk, wear or take off clothes or stand up from a chair, static electricity will be generated, which is also a dangerous spark source. According to tests, its energy is enough to ignite petroleum vapor. Therefore, in flammable environments, it is best not to wear chemical fiber clothing in places where there are dangerous explosives, hydrogen, acetylene and other substances.
