How to effectively remove the static electricity of laboratory equipment?

Will static electricity be generated in the use of laboratory equipment? The electrostatic disaster is caused by the four conditions of the generation of electric charge, the accumulation of electric charge, the phenomenon of discharge and the existence of combustible substances Is static electricity generated in the use of laboratory instruments harmful? How to prevent static electricity? 1 Laboratory instruments and equipment inhibit the generation of static electricity: because the source of static electricity is friction or separation between objects, so we should try to suppress these effects For example, in liquid pipeline transportation, dust air transportation or plastic extrusion and other operations, Zui's good way is to reduce the speed In fact, this will affect the work efficiency The safe flow rate of petroleum is less than 1 m / s Static electricity has different charge or polarity due to different substances Therefore, the feasible measure is to avoid using insulating materials which are easy to be charged, and to use materials which are difficult to generate static electricity through combination 2 Laboratory instruments and equipment promote the leakage of electric charge: in disaster countermeasures, Zui's simple method is to conduct grounding The method is to make the generated electric charge disappear into the earth rapidly through the metal conductor However, with this method, if the electrified body is a conductor, it can be simply eliminated, while plastic or chemical fiber, petroleum and other insulating materials, because the charge of the electrified part is difficult to move, the effect is not good 3 Eliminate the charged charge of laboratory instruments and equipment: in the case that the static charge is still carried out even though the occurrence of the charge is suppressed and the charge leakage is promoted, the static charge with should be eliminated actively For this purpose, the static eliminator can be used At present, various Static Eliminators are under development and sale At present, the de electrostatic device is using ions to remove electricity According to the generation mode of ions, there are three types: self discharge type, voltage additional type and radioisotope type 4 The electrostatic protection grounding of laboratory instruments and equipment often has dangerous potential in the place where flux, powder or other flammable products are handled, because the static electricity is accumulated on the equipment, processed materials and even on the operators When the electrostatic charge of laboratory equipment discharges to the ground or other equipment, it will inevitably cause fire and explosion when encountering inflammable or explosive substances, which will cause many casualties and property losses every year
