Descriere

Washing sets that clean plastic step by step, from coarse pre-washing to hot and intensive washing. The chain generally follows this order: pre-washing, for soil, stones, sand and paper; friction washing, which mechanically strips the dirt film and dehydrates; hot washing, which dissolves oils, adhesives and label glue in hot water, with detergent if necessary; density separation (sink-float), which removes unwanted polymers from the stream, PE/PP floating and PET/PVC sinking. The choice of steps depends on the type of contamination, the material (thin film, rigid, PET), temperature and detergent requirements, the cleanliness target and water recovery by filtration and recirculation. Equipment offered: friction washers, pre-washing, hot washing and intensive turbine washing units, sink-float separation tanks.
