Abstract

A method for processing, namely recycling, a workpiece made of electroplated plastic. In which method a coating is removed from the workpiece by a fragmentation unit by applying the electrohydraulic effect to a suspension containing plastic granules and containing coating granules. The suspension is dewatered, and a magnetic separator is used to separate the plastic granules from the coating granules by means of magnetic separation.

Abstract

The invention relates to a method for breaking down and comminuting a product by means of the electrohydraulic effect, in which, in a container (4) filled with a liquid, a discharge with a pulse energy or discharge energy less than 100 J, preferably between 1 J and 50 J, particularly preferably between J and 20 J, is generated substantially in the liquid by means of a pulse current source (SQ) within an underwater spark gap between at least one first electrode (9), in particular mass electrode, and a second electrode (10), in particular high-voltage electrode, the product to be comminuted lying in the spark gap in the continuous or discontinuous container (4). The invention also relates to a device (2) for breaking down and comminuting a product.

Abstract

The invention relates to a method for recycling composite materials by means of electrohydraulic reduction, whereby a separation of different materials, such as glass, semiconductors, metals, and polymers, is possible. The invention further relates to materials separated from the composite material which can be acquired in particularly high purity according to said recycling method.

Abstract

The invention relates to a method and a device for disintegrating a recyclable item in a material-selective manner and using the electrohydraulic effect, an electric discharge being generated, in a container filled with a liquid, using a pulsed current source and within an underwater spark gab between a container base-side electrode and at least one container cover-side electrode that points towards the first electrode, with electric discharge having an average field strength of less than or equal to 5 kV/mm and a pulse or discharge energy of greater than 10 J, and being generated at least substantially in the liquid. In the container, the recyclable item lies partially in the underwater spark gab on the container base-side.
