From April 26-27, 2023, relyon plasma will present the piezobrush® PZ3-i at the 43. ak-adp workshop in Leipzig as part of the #ZukunftADP 2021.
If surfaces are to be painted, printed or glued, they require good wettability of the surface for good adhesion. Many surfaces show insufficient wettability even in a clean state, which is intensified by impurities. As a result, the liquids roll off adhesives and inks. This can be prevented by plasma activation. Plasma activation of a surface increases the surface energy of the surface and creates deposition points for the applied liquid. This allows it to adhere very well.
The highlight of this year’s trade show appearance at Bondexpo is the presentation of the compact integration solution piezobrush® PZ3-i for the first time ever. The cold plasma device is designed for integration into existing production lines and is therefore compact, safe, and efficient. Thus, it is ideally suited for pre-treatment prior to gluing, printing, and laminating.
Surface energy Determination of surface energy by means of test inks and contact angle measurement, enhancement through plasma treatment Wettability is of major importance for all kinds of surface treatments like printing, varnishing and gluing. It describes the behaviour of liquids on solid surfaces which is dependent on the surface tension of the liquid and […]
Plastics are usually characterized by inert surfaces with surface energies between 20 and 40 mN/m. In order to wet a surface, however, the surface energy of the polymer must exceed the one of the paint or the adhesive. This condition can be achieved through a plasma treatment of the surface and is called "activation“ in plasma technology.
The high temperatures which are reached in most plasma applications make many users wonder about process safety, especially when highly sensitive materials are treated. This article addresses open questions concerning temperature and heat conduction during plasma applications and cites critical examples which substantiate the suitability of plasma for temperature-critical processes.
Our Plasmabrush® system, particularly the PS2000 high voltage unit, supplies meaningful digital process data from which valuable process information can be gained based on our years of expertise. In close collaboration with you, we define the operating points for your production steps and provide a working area designed to achieve the desired results.
