| 摘要 |
A coating installation, comprising at least one apparatus for pretreating the substrates to be coated (pretreatment installation), at least one apparatus for coating the substrate with coating substances (coating apparatus), and at least one apparatus for drying and hardening the applied coating substances (hardening apparatus), wherein at least one of the pretreatment installations comprises at least one arrangement for the anodic oxidation of the deionized, i.e. fully de-mineralized, water used in the pretreatment installation with at least one electrode, the electrode having a layer (3) of diamond, on a base body (1, 2) as shown in FIG. 1, and a method for sterilizing a pretreatment installation for a coating installation, in which deionized water used in the pretreatment installation is anodically oxidized with the aid of at least one electrode, which has a layer (3) of diamond on a base body (1, 2), the voltage at the electrode during operation always being below the potential range at which relatively large amounts of oxygen are evolved at the electrode.
