Durch ihren hohen Anteil an organischen Lösemitteln sind sie teilweise gesundheitsschädlich und zum Teil auch feuergefährlich. Außerdem entfernen sie im wesentlichen nur Verunreinigungen öliger oder fettiger Art.For this purpose, detergents of the most varied Kind used. So-called are widely used Cold cleaner. These cold cleaners are common Solutions of surfactants or surfactant-related substances in organic solvents. Hydrocarbons are used as solvents different boiling ranges common. This Known cleaning agents have a number of Disadvantages on. Due to their high proportion of organic They are partially harmful to health and partly also flammable. They also remove essentially only oily or greasy contaminants Art.

    Es wurden daher auch Reinigungsmittel auf wäßriger Basis entwickelt. Diese Reinigungsmittel weisen jedoch häufig den Nachteil einer nur geringen Reinigungskraft auf, falls nicht mechanische Hilfsmittel, wie Hochdruckwasserstrahl oder Ultraschall unterstützend eingesetzt werden.Therefore, cleaning agents were also used in water Base developed. However, these cleaners have often the disadvantage of a low cleaning power if not mechanical aids such as high pressure water jet or used to support ultrasound become.

    Erläuterungen zu Tabelle 1Explanations to Table 1

  • 1) Der Wärmetrübungspunkt ist die Temperatur, bei der bei Lagerung des Reinigungsmittels eine Trübung des Reinigungsmittels auftritt.1) The thermal cloud point is the temperature at which turbidity when storing the cleaning agent of the detergent occurs.
  • 2) Die Reinigungswirkung wurde bestimmt, indem Substrate (Stahlblech, verzinktes Stahlblech, Aluminium, Altlackierungen, Grundierungen und Kunststoffe) mit Hochdruckfett, Vogelkot, Poliermittel und Wachsen verunreinigt und 14-16 h/20°C antrocknen gelassen worden sind. Der Reinigungsprozeß erfolgte mit einem Lappen, der mit dem Reinigungsmittel getränkt war oder mit einem Pinsel. Unmittelbar nach der Reinigung wurde ein Spülvorgang mit Leitungswasser einschließlich anschließender Nachtrocknung (Heißluftgebläse) durchgeführt, um lackierunfreundliche Rückstände (Tenside etc.) zu entfernen.2) The cleaning effect was determined by substrates (Sheet steel, galvanized sheet steel, aluminum, Old paintwork, primers and plastics) with high pressure grease, bird droppings, polishing agents and wax contaminated and dry for 14-16 h / 20 ° C have been left. The cleaning process was done with a rag with the detergent was soaked or with a brush. Right away after cleaning there was a rinsing process with tap water including subsequent Post-drying (hot air gun) performed to paint-unfriendly residues (surfactants etc.) remove.
  • 3) Die überlackierbarkeit wurde bestimmt, indem sofort nach dem Trockenprozeß das Substrat zur Beschichtung mit einem Grundfüller und Decklack auf Polyurethan-Basis kam. Nach Alterung von 1 Woche/20°C ist ein Kurzwettertest durchgeführt worden. Im Vergleich zu lösemittelhaltigen Reinigungslösungen konnte kein negativer Einfluß auf Bläschenfestigkeit und Korrosionsschutz festgestellt werden.3) The paintability was determined by immediately after the drying process Coating with a primer and top coat came on a polyurethane basis. After aging 1 Week / 20 ° C a short weather test is carried out been. Compared to solvent based Cleaning solutions could not have a negative impact for bubble resistance and corrosion protection be determined.
