The Institute of Chemistry of the National Autonomous University of Mexico is studying a new method for recycling foam. This new method, known as "precipitation precipitation," uses an aqueous solvent to restore waste polystyrene foam to the original pellet state.
At present, the world mainly uses “melting granulation method†to recover foam plastics, which is melted and pressed into filaments after being melted at high temperature, and then cut into recycled plastic beads. However, the performance of the recycled beads is obviously better than that of the new balls. Pearl difference. The ball obtained by the new method is exactly the same in performance as the nascent ball after the foaming treatment, and can be immediately used in the production of a stamper.
According to the person in charge of the research project, the collected Styrofoam is put into a reusable commercial solvent, and the resulting mixed solution is dropped into water. The Styrofoam dissolved in it will be again Polymerization becomes a clean and easy separation of the original ball, these balls can be re-formed into a foam plastic products. At present, the research has entered the final stage of the extraction experiment. The institute will establish a small experimental plant to verify the practicality of the recovery method and determine the production parameters for commercial promotion.
