Cold active plasma system piezobrush PZ2

Is the PZ2 a corona treater?

No, the PZ2 is a jet with higher intensity and lower charging effects.

Which materials can be processed?

All Materials can be processed. For metals or conductors please avoid arcing at low working distance. Informations on working speed, working distance and surface effect, we refer to detailed application notes that you can get from our application engineers.

What is the optimum working distance?

For most of the polymers and isolators the best working distance ranges between 2mm and 5mm.

How fast should I move the PZ2 at optimum working distance?

For most of the polymers a substantial increase in wettability will be reached if the PZ2 is moved with 10mm/s to 50mm/s.

How much stronger will be my bond if I use the PZ2 before applying the glue?

The bond strength depends on material and glue. You will find many examples in our application notes.

How long does the surface activation last?

The surface energy will decrease after the treatment on a timescale of minutes to days. However the surface energy will allways remain higher than the initial value.

How can I test the surface effect with simple means?

Try to wet the surface with water or water based ink. If the ink spreads on the surface 72mN/m are reached.

Can I overtreat a component?

Typically the surface energy will quickly saturate. Overtreatment will not damage the material.

Can I use the PZ2 for cleaning off dirt?

Very thin layers of organics can be removed. Thick layers will not be removed efficiently.

Can the PZ2 kill microorganisms?

Yes, depending on the species and environment germs are efficiently inactivated or killed.

Are there special purpose nozzles for the PZ2?

Yes, specially for point treatment and conducting surfaces there are special nozzles. Please clarify your specific requirements with our application engineers.

How often should the white nozzle be exchanged?

Under normal operation the nozzle will last for much more than 100 hours. If staining or color change is visible the nozzle can be changed easily.

Does the PZ2 emit UV light?

Yes, but the UV emission using air is of low intensity and harmless.

How high is the ozone emission?

Operated with air the PZ2 produces ozone wit a maximum concentration of 10ppm and a rate of 25L/min. If used continuously, an active carbon filter or an hood should be used.

Can the PZ2 cause skin damage?

Yes, if the PZ2 is placed close to the skin, local burn pattern can cause superficial skin damage.

Can the PZ2 cause dangerous electric shock?

No, the amount of charge and the current are too low to be dangerous.

Atmospheric plasma system plasmabrush PB3

Which materials can be processed?

All Materials can be processed. For thermally sensitive materials the choice of the nozzle and suitable working speed and distance are crucial. Informations on working speed, working distance and surface effect, we refer to detailed application notes that you can get from our application engineers.
