Abstract

Here the description of the possibility of processing technogenic waste polystyrene in binder materials for foundry is provided. The possibility of dissolving polystyrene foam in acetone. Regardless of the amount of acetone that was analyzed, polystyrene absorbs it in a 1:1 ratio, with the formation of a swollen precipitate. The obtained data of the study “polystyrene–acetone” have been successfully used as the basic elements of technology for cellular polystyrene models with implants. Here the prime factor imposing is the kinetics of polystyrene foam in acetone swelling and the swollen foamy polystyrene precipitate composition. The precipitate can be used as a binder for molding compounds. The kinetics of swelling of polystyrene foam and beaded polystyrene in acetone was studied. The data obtained in the study of the system “polystyrene foam–acetone” was used in the manufacture of polystyrene models with implants. The technology for producing polystyrene foam models with implants includes the need to use a special binder for fixing implanted granules on the surface of implanted granules. The research results allowed to propose a new technology for producing foam polystyrene models with implants without using a special binder.
