• Separating The Plastics By Flotation

Separation of waste plastic resulting from electrical

Aug 09, 2021The separation of four waste plastic samples - Polyvinyl chloride (PVC), Acrylonitrile butadiene styrene (ABS), Polycarbonates (PC), and Polyamides (PA) resulting from electrical products in three bicomponent plastic mixtures (PVC-ABS, PVC – PA, and PVC - PC) was performed by using four different flotation solutions (5%, 10%, 20%, and 30% concentration) of CaCl 2.

Clarifier

Clarifiers are settling tanks built with mechanical means for continuous removal of solids being deposited by sedimentation. A clarifier is generally used to remove solid particulates or suspended solids from liquid for clarification and/or thickening. Inside the clarifier solid contaminants will settle down to the bottom of the tank where it is collected by a scraper mechanism.

The plastic sorting challenge

Once plastics are separated, the labels are carried off on a separate airstream. Initially the project's fluorescent markers were developed by selectively recovering rare earths from used fluorescent tubes and lamps: a new chemistry to extract and restructure them was developed with Imperial College London and Brunel University in the UK.

Sink

A sink-float tank is often used in a plastic recycling line as a washing machine. With paddles rotating at the water level, in-feed materials scramble and rinse in the tank. Mingled materials are scattered apart and got wet. A majority of contaminants can be eliminated when the material goes through the ups-and-downs of rotating paddles.

How Do You Separate Sand, Salt and Iron Filings?

Apr 07, 2020Spread the sand, salt and iron mixture on a flat surface. Wrap the magnet in the paper towel. Use the magnet to remove the iron by pulling it across the surface of the mixture. The filings stick to the magnet while the sand and salt are left behind. Remove the paper towel from the magnet to collect the filings. Use warm water to dissolve the salt.

Selecting chemicals for separation of ABS and HIPS in WEEE

Froth flotation allows for separating particles by the differences in their surface characteristics by selective wetting agents. The common chemicals are ethanol and acetic acid to depress the plastics. The process with 20% weight of ethanol was able to produce a recovery concentrate of HIPS with 98% and ABS with 96%.
