Conference room carpet, static electricity is particularly serious, how to remove? How can I get the equipment grounded? What are the specific requirements?
The use of electrostatic elimination agent, the use of electrostatic elimination agent, scrub the instrument and surface of the object, so that the surface of the electrostatic elimination of the object. Antistatic agent takes grease as the raw material, and the main component is Ji Anyan. Its function is to make the surface of chemical fiber, rubber, plastic and other objects adsorb the moisture in air and increase the conductivity. 4) control the temperature and humidity of the environment, control the temperature of the computer room, control the free and penetrating speed of various objects in the computer room, and reduce the generation of the static charge. The influence of humidity on electrostatic room is large, medium in a humid environment, moisture adsorption phenomenon, adsorption of water will lead to improve the surface conductivity of dielectric objects, so that the static charge leakage capacity increases, the attenuation of the electrostatic charge is greatly accelerated. But the room environment humidity can not be unlimited increase, should also consider equipment, electronic components, such as short-circuit, leakage and other factors. Under normal circumstances, the humidity of the computer room can be controlled between 50%-60%. Use humidifier, precision air conditioning and other equipment, can effectively control the humidity environment of the engine room.
Practice is not the same, the equipment grounding, as mentioned above, is a factory overall planning. In the early days of electrical installation, there was a bus. Just connect the equipment. But it is a monomial electrostatic grounding. Such as a PCB turnover car, as long as a separate static chain, to achieve anti-static effect. ESD protection 1) grounding is the connection of some antistatic products or other equipment to a ground wire. The method of buried line is used to establish "independent" ground wire. The resistance between the earth and the earth, < 10, acts as a potential charge on the discharge conductor. The grounding method is that the human body is grounded through the wrist band; the human body is grounded by the anti-static shoes and the anti-static floor; the work surface is grounded; the testing instruments, tools, clamps, irons and other grounding; anti-static floor, floor mats, grounding and so on. 2) the use of static elimination equipment such as ion fan, ion wind guns, is the electrostatic eliminator good, its principle is to produce positive and negative charges in a static eliminator, then put these charges to the place by electrostatic blowing wind, electrostatic charge polarity will be opposite in and out. The static electricity elimination equipment also has the human body static electricity release alarm device, the human body static electricity eliminator, the clean room, uses the vacuum cleaner, the ion wind mouth, the ion wind stick and so on.
The equipment grounding and grounding equipment, the principle is the same, but the function, the purpose is not the same, specifically: 1, equipment grounding for safety, prevent leakage caused harm to the human body, such as appliances, equipment and electrostatic grounding to equipment because of its various reasons to produce static charge accumulation (such as object friction) release, does not constitute a component jihuai.
