rely on plasma technology PiezoBrush PZ3 Effective plasma handheld device

Effective plasma device for manual use PiezoBrush PZ3 has been designed as a compact plasma handheld device for use in laboratories, predevelopment and assembly of small series. With a maximum power consumption of 18 W, the Piezoelectric Direct Discharge (PDD®) technology is used to generate cold active plasma at a temperature of less than 50°C. Plasma is used to increase the surface energy of many materials with high efficiency, as well as to reduce germs and odors. ◊ Joining technology ◊ Development and optimization of production processes ◊ Research facilities and laboratories ◊...

Introduction to surface treatment For processing and end use of materials, their surface properties are of vital importance. These can be positively influenced by selective surface treatment with plasma to achieve an ideal end result. For example, the cleanliness and wettability of a surface are of decisive importance for adhesion in bonding, printing, painting or coating processes. Even in a clean state, many surfaces exhibit insufficient wettability, which is further worsened by contamination. As a result, liquids such as glue or ink will bead off and cannot adhere. This state is referred...

Optimized adhesive bonding with plasma If a surface is functionalized with plasma before bonding, the following bonds show a significantly improved adhesion. Plasma can be used on a variety of materials: Metals, glass, ceramics and even natural materials such as wood, natural fibres and textiles react very well to plasma treatment. The adjoining table shows a comparison of the ultimate tensile strength of 2K epoxy bonds between untreated plastics and bonds between the same plastics with previous plasma treatment. The comparison shows a significantly improved adhesion. Ultimate tensile...

Plasma activation with PiezoBrush PZ3 Plasmatreatment prior to printing Plasma treatment improves adhesion of printing inks and varnishes on the surface, thus significantly enhances the print quality. The illustration shows a droplet of ink applied to a surface and below the subsequent print result. The first droplet has a high contact angle of more than 90° and therefore wets the surface poorly, which causes the ink to contract on the surface and is not distributed evenly. The best result is achieved when the contact angle is 0° - the ink wets the surface optimally and creates an even...

Which materials can be treated? In principle, all materials can be treated with atmospheric pressure plasma from the PiezoBrush PZ3 handheld plasma device. This surface treatment with atmospheric-pressure plasma hardly causes any temperature input on the material, which also has the advantage that there is no risk of overtreatment even with temperature-sensitive materials such as plastics. Plastics and composites Metals and metal alloys Glass, ceramics, natural stone Natural leather, artificial leather Natural fibre, wood, paper The following diagrams give an overview which materials are...

Exchangeable modules and display Different surfaces have to be activated with the appropriate accessories to achieve an ideal result. Currently two different exchangeable modules are available for the PiezoBrush PZ3 plasma handheld device. The PDD technology used to generate the cold plasma in PiezoBrush PZ3 is based on the discharge of high electric fields. Therefore, the electrical conductivity of the component to be treated is of decisive importance when choosing the modules. Module Standard This module is designed for the surface treatment of non-conductive substrates such as plastics,...
