Static damages the material
The most common method of charge generation is triboelectric charging. Whenever materials are brought into close contact, a charge exchange may occur between the surfaces of the two materials. The magnitude of this charge exchange will depend on a number of factors, but the result is two oppositely charged objects full of charged ions when the materials are separated. Air ions are molecules of one or more of the gasses that make up air (nitrogen, oxygen, carbon dioxide, etc.) that have gained or lost electrons. In production processes, static electricity can often be a severe disruption. This can be caused by static cling, shocks and other kinds of damage. However by static elimination you can control the static in processes.
“Charges over 100 kV are not uncommon”
The Problem
Static electricity that creates a static charge on a material can build up along the process. Friction between idle rollers and film create a charge that can become severalk kilovolts. Each new friction accumulates the amount of static electricity and results in a higher charge. Charges can rapidly become very high. Charges over 100 kV are not uncommon. When a static charge exceeds a certain level, spontaneous discharges and sparks can occur causing damage to the material or electronic equipment in the vicinity.
Most common solutions to static problems can be found HERE.
The Solution
Work backwards in the process from the point where sparks have occurred. Place anti static bars prior to the idle roller. In most cases static charges are too high to be eliminated by one stage of anti static bars. Additional anti static bars are needed to control the static charge from the beginning to the end of the process.
