Pyrolytic technology
About the tecnhology...
At our Debrecen site, the cleaning of metal parts is carried out in a domestically manufactured, TKA 16.35 pyrolysis furnace. The pyrolytic technology based on heat treatment results in a clean metal surface in an environmentally friendly way.
Areas of application
- Cleaning of parts used to apply paint, varnish, adhesive and other organic materials
- Paint-defected end parts
- Cleaning metal-plastic composition parts to reclaim metallic materials
- Treating parts before repainting
- Soft-cleaning parts used in plastic-molding areas (filters, tools, pulleys, nozzles)
- Cleaning complex, or uneven heat-sensitive parts
Description of the cleaning technology
The workpieces are cleaned in the sealed space of the gas-fuelled pyrolysis furnace, in a low-oxygen environment. The parts to be cleaned are placed on the loading table located on the roller conveyor in front of the furnace door.
After the table is pushed inside the furnace and the operating space is hermetically sealed, the interior space is slowly heated up by the hot air of the gas burner to 450 °C. At this temperature, organic substances decompose and their degradation products are transferred to another section of the furnace: the post-combustion chamber, that is constantly maintained at a 750 °C temperature; here, the organic substances are fully and completely incinerated.
After cooling down, the workpieces can be removed from the table and a new cycle can be initiated. The removed parts might undergo post-treatment afterwards, depending on the customer’s needs.
