Buy static elimination equipment precautions
Recently, many customers have reported that static elimination equipment has no effect in using static electricity in the laboratory. In fact, from now on, we can see the importance of static elimination equipment in it.
Is static electricity generated during the use of laboratory equipment? Static disasters occur due to the four conditions of charge generation, charge accumulation, discharge, and flammable substances. Is the static electricity generated during the use of laboratory instruments harmful? So how to prevent static electricity?
1. Laboratory equipment and equipment suppress the generation of static electricity: Since the source of static electricity is the friction or separation between objects, it is necessary to suppress these effects as much as possible. For example, in liquid line transport, dust air transport, or plastic extrusion, the best method is to reduce the speed. In fact, this will affect the efficiency of the work. The safe flow rate of petroleum is below 1 m/s. Static electricity is charged or polarized depending on the substance. Therefore, a feasible measure is to avoid the use of an easily charged insulator, and to use a material that is difficult to generate static electricity by combination.
2, laboratory equipment to promote the occurrence of charge leakage: in disaster countermeasures, the easiest way is to ground. The method is to cause the generated charge to quickly disappear into the earth through the metal conductor. However, with this method, if the charged body is a conductor, it can be easily eliminated, and an insulator such as plastic or chemical fiber or petroleum is difficult to move due to the electric charge of the charged portion.
3, laboratory equipment to eliminate the charged charge: in the case of suppressing charge generation, causing charge leakage, still with static electricity, should actively eliminate the static electricity. A destaticizer can be used for this, and various destaticizers are currently being developed and sold. The static elimination device currently developed uses ion to remove electricity. According to the ion generation method, there are three types: self-discharge type discharger, voltage-added type discharger, and radioisotope type discharger.
4, laboratory equipment, electrostatic protection, grounding
Where flux, powdered materials or other flammable products are handled, hazardous potentials are often present because static electricity builds up on the equipment, on the treated material, and even on the operator. The electrostatic charge of laboratory equipment is discharged to the ground or other equipment. When it encounters flammable or explosive substances, it will inevitably cause fire and explosion, resulting in many casualties and a large amount of property loss every year.
