What should be the air gap between the electrodes?

The air gap between the electrodes varies from 1mm to 2.5mm according to different materials, but the gap between the electrodes must be constant. We recommend setting the pitch to 1.5mm. However, if the material is quite thick or the part to be spliced or thick at the tail is thicker, the spacing can be increased appropriately.

The minimum pitch is 1mm. If the distance between the store and the ground roller is small, pay attention to cooling the electrode and ensure that its temperature does not exceed the safe operating temperature.

Please refer to the machine manual for the procedure of correcting the gap. If you need an instrument to measure the electrode gap, please contact us and we will provide you with a meter for free.

What is the life of the electrode?

With proper cooling and processing, ceramic electrodes can be used continuously for two years. The key to extending its life is cooling. Overheating is the primary cause of electrode failure after physical damage. As long as ceramics are completely used as the dielectric material of the electrodes, the electrodes can provide stable performance day after day and year after year. Ceramics provide a dielectric or buffering effect to prevent arcing directly to ground.

Can the electrodes be repaired when needed?

If the ceramic is broken or small holes appear, the electrode cannot be repaired. If the high-voltage wire or fixing sleeve is broken but the ceramic tube is intact, the electrode can be repaired.

When summer comes, how can we ensure that the production of surface treatment machines is optimized?

The biggest problem with the corona processing system is machine failure. Power problems are the root cause of machine failure. Dust, humidity buildup, and film residues cause a comprehensive destructive effect and cause high voltage failures. Heat-dissipating components are blocked, and electrode insulators and accumulations on high-voltage components are potential problems that can cause failure. The best way to ensure reliability is to keep these places clean.

Will there be vibration feedback after the system's unit is turned off?

But the electric shock is the stored electrical energy acting on the raw material through electrostatic form. When the power of the corona processing system is turned off, the electrodes will not be charged. It is common for static electricity to be generated and discharged during film processing. There are many factors in a corona processor that can generate static electricity. A simple movement of the substrate on the roll can also generate static electricity. If the roll does not rotate ... or if the speed is slower than the substrate moves ... it will double the static electricity generated. Environmental conditions such as temperature and dew point in the air are factors that can cause static electricity to double. There are various commercial devices that can reduce or eliminate static electricity.

Which factors need to be given priority during the installation of the debris removal system?

Each system requires a specific exhaust air volume and static pressure to cool the electrodes, and the ozone generated in the corona is also removed. The equipment required for the specified exhaust system is listed in the machine installation sketch. The diameter of the ventilation pipe needs to meet the minimum loss of air flow. Another need to consider is to reduce the length of the pipe and the number of bends, or to connect to the outdoor unit when changing direction. If there are any problems related to the piping system, you can contact Q & E Static Services to review the installation.
