  • This floating rice cake-like material is a polystyrene mass itself, and can be a plastic raw material that can be used for various purposes by a simple operation. Also foam Since styrene does not dissolve, it has the distinct advantage of being very easy to separate from the excipient. In addition, when the 'concentrating agent' of the present invention is used, dust is separated without being caught in the polystyrene mass, so that a high-quality polystyrene mass can be obtained without the dust being mixed into the styrene foam mass. It also has the advantage of being able to. In this way, it is possible to regenerate plastic raw materials without requiring large equipment and costs.
  • the new styrene foam volume reducer does not dissolve the polystyrene in the solution, so it is very economical to take out the moist polystyrene mass and then replenish the solution.
  • the rice cake-like polystyrene mass does not dissolve in the new polystyrene foam reducing agent, so the new polystyrene foam reducing agent is hardly contained in the mass, and this is economical.

Abstract

L'invention concerne un agent réducteur de volume pour mousses de polystyrène n'ayant aucun effet ni sur le corps humain ni sur l'environnement et pratique. L'agent réducteur de volume est obtenu par addition à un solvant pour mousses de polystyrène d'un agent insolubilisant dans lequel les mousses de polystyrène sont insolubles mais lequel est soluble dans le solvant destiné aux mousses de polystyrène. Lors d'un contact avec l'agent réducteur de volume, une mousse de polystyrène prend la forme d'une matière grumeleuse flottant sur celui-ci sans dissolution dans l'agent réducteur de volume. En nettoyant la matière grumeleuse on peut obtenir une matière de polystyrène brute à partir de laquelle on peut régénérer une mousse de polystyrène.
