Waste plastics are usually contaminated with various oils, dust, sand and garbage to varying degrees. These external impurities attached to the plastic surface must be cleaned to improve the quality of the recycled products. There are two types of cleaning methods: manual cleaning and mechanical cleaning. Cleaning and drying of toxic drug packaging bags and windows: lime water cleaning (neutralization and disinfection) → brushing → cold water rinsing → drying Reed Switch Fuel Level Sensor, also called float fuel level senosr, it is done by sealed reed switches positioned inside the main shaft of the sensor. A float with built-in magnets then triggers the reed switch relays, generating a potential-signal with resistance, current, or voltage value that increases or decreases according to the fluid level, then give the signal to the gauge via wires, which shows the right level reading by pointer. In the whole reed switch level sensors,the float is the only moving part of the sensor,thereby minimizing potential mechanical failures to get the precision measurement.

The variety of waste plastics is different from the degree of pollution, and the specific cleaning methods are also different.
Cleaning and drying of agricultural film and packaging materials: alkaline water cleaning (removing oil) → brushing → cold water rinsing → drying
