摘要:
The present invention relates to a method for powder coating a plastic or glass object, comprising the steps of forming a polar coating on the plastic or glass object, comprising the sub-step of applying a coating composition to the plastic or glass object, wherein the coating composition contains a organosiloxane, which has at least two Si-O bonds, water, an organic solvent and a pH-regulating means, selected from a Bronsted acid, in a catalytic quantity, with the proviso that the coating composition does not contain any electrically conductive additives, selected from ionic compounds, metals, metal (mixed) oxides, intermetallic compounds and conductive carbon. The method also comprises the steps of applying a powder coating to the plastic or glass object thus coated and of heating the powder coating.

The invention relates to a method for determining properties of a pipeline, more particularly the position of a branch in a waste water pipeline, in which: a sound wave transmission signal (S, S') is fed into the pipeline (1) at a predetermined infeed point and propagates in the axial direction of the pipeline (1), wherein the frequency spectrum of the sound wave transmission signal (S, S') has a frequency component or a spectral range, the maximum frequency of which is lower than the lower limit frequency (f c ) for the first upper mode; in which method components (Sr1, Sr2, Sr3, S'r1, S'r2, S'r3) of the sound wave transmission signal (S, S') reflected inside the pipeline (1) are detected as a sound wave reception signal (E, E'); and in which method, by evaluating the sound wave reception signal (E, E') in relation to the sound wave transmission signal (S, S'), the pipeline (1) is examined for the presence of reflection sites along the pipeline (1) that cause sound wave reflections (Sr1, Sr2, Sr3, S'r1, S'r2, S'r3), wherein at least the distance (I) of a reflection site from the infeed point is determined by evaluating the respective sound wave reception signal (E, E'). The invention further relates to a device for implementing said method.
