    摘要: A lacquer basin (12) for a dip coating device (10) is provided. The lacquer basin (12) comprises an inlet section (12a) arranged at a lower end of the lacquer basin (12) and adapted to receive a stream of a lacquer mixture (14) injected into the lacquer basin (12). The lacquer basin (12) further comprises a process section (12b) adjoining the inlet section (12a) at an upper end of the inlet section (12a), wherein the process section (12b) is adapted to provide a process volume for dip coating one or more objects in the stream of the lacquer mixture (14). The lacquer basin (12) is characterized in that it comprises a diversion element (22) arranged at or near a transition from the inlet section (12a) to the process section (12b) and adapted to divert at least a part of the stream of the lacquer mixture (14) such as to reduce or avoid turbulences of the stream of lacquer mixture (14) in the process section (12b). The lacquer basin (12) is characterized in that the diversion element (22) comprises two or more barrier layers (24) arranged at different levels spaced apart from each other, wherein each of the barrier layers (24) has multiple recesses (28) and intermittently covers the cross sectional area of the lacquer basin (12)

    摘要: The invention relates to a wet chemical method for coating metal surfaces with spin transition compounds by gradually applying components of the spin transition compound to the surface to be coated, characterized in that a) the metal surface is brought into contact with an organic spacer, after a pre-treatment as applicable, which organic spacer comprises at least one anchor group that is capable of binding to the surface and at least one ligand group that is capable of coordinating transitional metal ions, in order to obtain a surface coated with the spacer; b) the spacer-coated surface is brought into contact with a solution of the transitional metal ion forming the central atom of the spin transition compound, in order to bind the transitional metal ion to the at least one ligand group of the spacer; whereupon c) a solution of the remaining ligands is applied to the spin transition compound in order to form the spin transition compound in situ on the surface.

    摘要: The invention relates to a device for processing a metal strip (200) after said metal strip has exited a coating tank (300) having liquid coating material (310). Above the coating tank, the device has a blow-off apparatus (110) having an air outlet slot (112) for blowing liquid parts of the coating off of the metal strip. Arranged above the blow-off apparatus (110) is an electromagnetic stabilization apparatus (140) for stabilizing the metal strip by means of electromagnetic forces after the exiting of the coating tank and the blow-off apparatus. According to the invention, in order to design known devices for treating a metal strip to be more favorable in respect of energy and in order to increase the accessibility of said devices for an operating person, the stabilization apparatus (140) is arranged above the blow-off apparatus (110) in such a way that the distance d between the line of action of the maximum force of the stabilization apparatus on the metal strip and on the air outlet gap (112) of the blow-off apparatus (110) is limited to a range of 100 - 1200 mm.
