Compounds

Compounds are added to the disc finishing machines during the grinding process in order to produce clean, bright and non-corroded workpiece surfaces. With impact-sensitive workpieces, the compound creates a foam buffer betweem the workpieces and the abrasive media. The compounds supplied by OTEC not only provide the best possible finishing results, but are also easy to break down in the waste water treatement system because they do not contain strong complexing agents.

Compounds for fresh water processes

In fresh water processes, the compound is added to the water as a percentage of the water flow rate. The used water is then transported into disposal containers or goes straight to the waste water treatment process and is not reused.

SC 25 Wet grinding, wet polishing For non-ferrous metals (especially aluminum), brightening 5 1-5%

 

Compounds for recirculation processes

In recirculation systems with cleaning centrifuges, a higher concentration of compound must be used relative to processes that do not reuse the water. The compound is added during the preparation of the process water. All that remains while the system is running is to top up the compound in the centrifuge to replace what is lost in sludge removal. Recirculation compounds produce less foam and have a higher contamination-removal capacity compared to fresh water compounds.

Type Application Description pH value

), with anti-corrosive z, low foaming
9.5
SC 41 Wet grinding Universal compound with very good oil transport,
anti-corrosive, low foaming
9,1
