At parts2clean in Stuttgart in October, Plasmatreat GmbH (Hall 10, Stand D52) will be presenting a solution for industrial surface cleaning that removes particularly stubborn organic and inorganic residues in equal measure. The plasma specialist has equipped its Plasma Treatment Unit (PTU) with the latest technology and is bringing this system to the trade fair. HydroPlasma, the combination of open-air plasma and distilled water, enables efficient, environmentally friendly and gentle preparation of substrates for demanding finishing processes such as structural bonding, sealing or coating.
Live demo and fluorescence analysis
Visitors can get to know the new HydroPlasma process live. The PTU is equipped with open-air and HydroPlasma. Metal parts contaminated with fingerprints or oil residues are cleaned and analyzed live. The Fraunhofer IPM's fluorescence scanner is also used here. Its analyses use before and after images to illustrate how different the surface cleanliness is before and after treatment. Visitors can bring their own flat material samples, which are cleaned on site and then analyzed by scanner.
Acid and hydrogen radicals dissolve residues on surfaces
HydroPlasma combines the physical cleaning effect of open-air plasma, also developed by Plasmatreat, with the chemical reactivity of water. By feeding distilled water into the plasma process, highly reactive oxygen and hydrogen radicals are created. These dissolve residues on surfaces into water-soluble or gaseous components that can be removed without leaving any residue. The technology works in an environmentally friendly way using water, air and electricity, without chemical solvents and is VOC-free. The water injected makes the plasma jet that hits the surface colder than usual, enabling even more temperature-sensitive materials to be treated.
