Method of controlling static electricity in thermal shock test chamber

1. thermal shock test chamber Inhibit the generation of static electricity: Since the source of static electricity is friction or separation between objects, it is necessary to suppress these functions as much as possible. For example, it is a good way to reduce the speed in operations such as liquid pipeline transportation, dust air transportation or plastic extrusion. In fact, this will affect the efficiency of the operation. The safe flow rate of oil is less than 1m/s. The amount or polarity of electrostatic charge varies from substance to substance. Therefore, a feasible measure is to avoid the use of insulating materials that are easy to charge, and use materials that are easy to generate static electricity through combination.

2. Promote charge leakage: In thermal shock test chamber disaster countermeasures, the simpler method is grounding. This method is to make the electric charge disappear quickly to the earth through the metal conductor. However, with this method, if the charged body is a conductor, it can be simply eliminated, while insulators such as plastic, chemical fiber, petroleum, etc., because the charge of the charged part is difficult to move, the effect is not great.

3. Another method is to thermal shock test chamber add conductive material to the object to leak the charge. Including adding metal powder or carbon black to tires or operator's boots and floor materials of chemical plants, and using hydrophilic oil in chemical fibers or plastics to prevent electrification. If the relative humidity in the air is increased, a water-absorbing layer will be formed on the surface of the object, which will enhance the conductivity, and it will hardly be charged when the humidity is above 80%. Therefore, where there is a possibility of electrification, you can increase the humidity by adjusting the humidity device or sprinkling water. But the problem is that people may feel uncomfortable or have an adverse effect on equipment and products.
