WebApr 1, 2014 · Just about all of us have walked across a nylon carpet and generated static electricity. If the relative humidity is low, a charge in excess of 25,000 volts can be generated. ... A soft failure caused by a static discharge event may only injure the ESDS part and cause unreliable operation and/or shorten the life of the overall system. WebHumidification is a very effective way to eliminate the build-up of static electricity in manufacturing environments. By keeping the humidity at 55%RH the moisture content of the air is a natural conductor and earths any potential static charge. Static build-up in manufacturing environments often causes a reduction in productivity, a drop in ...
WebFor the correct use of flammable products, such as paints and solvents, it is essential to know the risks involved in their handling.A key element in this regard is static electricity. The generation of electrostatic charges occurs as a result of the relative movement between two surfaces that are in contact, where one or both of them is not a good electricity conductor. WebFor example, applications in drier environments tend to require slightly higher humidity levels to avoid static discharge, brittle materials, and other issues caused by insufficient humidity. For most electronics manufacturing environments, optimal humidity levels tend to range from 30% to 70% .
