How to Prevent Electrostatic Production from Preventing Electrostatic Production？
How does industrial production prevent static electricity? To prevent static electricity must first try not to produce static electricity; on the static electricity generated, should be limited, so that it can not reach the extent of danger. Followed by the leakage of the generated charge as soon as possible or neutralization, thereby eliminating the accumulation of a large amount of charge.
At present, the world control the flow rate of the standard is not uniform. In determining the flow rate, not only to consider the inner diameter of the pipeline, but also pay attention to the nature of the fluid, the composition and quantity of impurities, the material of the pipeline and other factors. The flammable liquid flowing in the pipe, even with a higher average charge density, tends to show a higher voltage due to the larger capacitance in the pipe and in the pipeline because there is no air, Burning and exploding. In this case, although static electricity does not pose a danger inside the pipeline, its serious hazards are mainly at the exit of the pipeline, which must be taken seriously.
The role of electrostatic grounding is to drain the conductor may gather the charge, so that the conductor and the earth equipotential, so that the potential difference between the conductor is zero.
Reduce the resistivity
When the resistivity of the substance is less than 106 Ω · cm, the accumulation of electrostatic charge can be prevented. Method of reducing resistivity:
A. Add conductive filler; B. Using anti-static agent.
Increase air humidity
When the relative humidity of the air in the 65-70% or more, the surface of the object will often form a layer of very thin water film. Water film can dissolve CO2 in the air, so that the surface resistivity greatly reduced, static charge is not easy to accumulate. If the relative humidity of the surrounding air down to 40 to 50%, the static electricity is not easy to escape, it is possible to form a high potential. The common method of increasing air humidity is to spray water mist in the air, usually use rotary fan sprayer, but the machine is not explosion, must be blown from the wall.
The use of static eliminator to ionize the air in the oxygen, nitrogen ions, so that air into a conductor, can effectively eliminate the electrostatic charge on the surface of the object. Commonly used stati
