Rigid polymers
Clean as a whistle: pure polymers thanks to excellent washing results
Challenge
Polymer waste is often contaminated with organic materials that can give off strong odours. It also often contains admixtures of other polymers, which makes cleaning more difficult. Finally, due to the complex surface structure of 3D particles, there are numerous places where impurities can develop.
Solution
Effective cleaning of 3D plastic particles must achieve three main goals. First, it is necessary to clean contaminated indentations on the surface of the particles. This can be done very efficiently thanks to the hydrodynamic friction generated by our HydroCleaner. Second, a classification step is required to remove foreign polymers. This is where our AeroSeparator comes in. Third, any recontamination of the plastics by contaminated process water must be prevented. Separate water circuits, ultrafiltration and our HydroDyn firewall ensure that the polymers remain clean.
In a nutshell
the outstanding features of HydroDyn technology
Deep Cleaning
The hydrodynamic friction generated by the HydroCleaner removes dirt even from surface indentations.
Smart Process Water
Separate water circuits, ultrafiltration and the HydroDyn firewall guarantee the outstanding purity of the recyclate. This minimises recontamination from process water and also reduces water loss.
Cold Wash
The principle of hydrodynamic friction ensures clean separation of film parts and unparalleled cleanliness, even in the case of adhesive contamination – and without the need to wash using hot water.
