Embodiment Construction

[0024] figure 1 A surface 1 is shown, which is covered with a layer 2 of UV-cured ink. A solvent-free cleaning agent 3 is applied to the part of the surface 1 by the spray head 5, which reduces the adhesion of the UV-cured ink layer 2 on the surface 1, which here does not dissolve. figure 2 A surface 1 to which a cleaning agent 3 is applied is shown. After about 3 minutes of action, the excess cleaning agent 3 is removed with a liquid-absorbent cloth 6 . The parts of the surface 1 treated with the cleaning agent 3 are now rinsed with water 7 and dried, for example, with a cloth 8 or a blower. After drying, such as image 3 As can be seen in , the adhesive film 4 is applied to the part of the surface 1 treated with the cleaning agent 3 . The adhesive film 4 is removed again after it has been applied to the surface 1 . In this case, the ink 2 treated with the cleaning agent 3 adheres to the adhesive film 4 and is removed together with the adhesive film 4 from the surface ...

Abstract

The present invention relates to a method of removing hardened ink or replacing paint or lacquer from a surface, wherein a cleaning agent is applied over the ink on the surface. The method is characterized in that the cleaning agent applied to the ink on the surface is substantially solvent-free and water-based and reduces ink adhesion on the surface without dissolving the ink, wherein the one-sided adhesive element is placed on the surface with the sticky side, and the substantially insoluble ink treated with the cleaning agent adheres to the sticky element when it is removed from the surface and is thus removed from the surface together without breaking apart .

Description

technical field [0001] The present invention relates to a method of removing hardened ink (or alternatively paint or lacquer) from a surface. Background technique [0002] Conventional methods for removing hardened ink, paint or lacquer layers using dissolved cleaning agents regularly lead to a stress on the surface. In order to effectively remove the ink layer, the surface is primarily additionally acted on mechanically by friction or sliding. This can lead to damage or undesired changes to the surface. Furthermore, the ink layer is only removed piece by piece. Furthermore, this can result in the smallest ink sticks, which again adhere to the surface and have to be removed in a time-consuming second cleaning step. This method of removing the ink layer has proven to be difficult especially in the case of strongly curved surfaces. [0003] A device for cleaning circuit substrates is described in EP 1875490B1. In an embodiment of said invention, the circuit substrate pass...
