Waste plastics are often stained with various oils, dust, silt, and rubbish, to varying degrees, and these external impurities attached to the plastic surface must be cleaned to improve the quality of recycled products. Cleaning methods include manual cleaning and mechanical cleaning.
The type of waste plastic is different from the pollution level, and the specific cleaning method is also different.
Cleaning and drying of agricultural film and packaging materials: alkaline water cleaning (oil removal) → brushing → cold water rinsing → air dry.
Toxic pharmaceutical packaging and window cleaning and drying: Lime washing (neutralization) → Brushing → Cold water rinsing → Drying.
