The Max Planck Institute for Astronomy uses the piezobrush PZ2 for plasma activation of CFRP and glass/glass ceramic adhesive surfaces.
The surface treatment of glass with plasma technology has been established in practice for many years. Without pre-treatment glass has a typical surface energy of 47mN/m. After plasma treatment, the surface energy increases significantly. Treatment with the high-power plasma system plasmabrush PB3 achieves a surface energy of >72mN/m and with the handheld plasma unit piezobrush PZ2 a surface energy of >67mN/n. Test inks according to DIN ISO 8296 were used for the test.
A typical application example is bonding glass. The following table shows the improvement of the average adhesive strength after plasma treatment compared to untreated glass substrates.
|Glass||Epoxy glue||piezobrush||5,43 N/mm²||0,37||>3,7 times|
|piezobrush||0,85 N/mm²||0,04||>3,5 times|
