PROCEDE DE FABRICATION DE MELANGES DE MATIERES SYNTHETIQUES THERMOPLASTIQUES ET DE MATIERES DE REMPLISSAGE MINERALES OU ORGANIQUES ET DISPOSITIF POUR SA MISE EN OEUVRE

DANS CE PROCEDE LES MATIERES DE REMPLISSAGE SONT CHARGEES ELECTRIQUEMENT OU ELECTROSTATIQUEMENT AVEC LES MATIERES SYNTHETIQUES AVANT ETOU PENDANT LE MELANGE.LES MATIERES SYNTHETIQUES PEUVENT ETRE EGALEMENT CHARGEES ELECTRIQUEMENT OU ELECTROSTATIQUEMENT AVANT ETOU PENDANT LEUR MELANGE AVEC LES MATIERES DE REMPLISSAGE.LA CHARGE OBTENUE RESTE STABLE PENDANT UNE LONGUE DUREE, CE QUI PERMET D'APPLIQUER UN TRAITEMENT PREALABLE ET SEPARE A LA MATIERE DE REMPLISSAGE AVANT LE MELANGE, AINSI QU'UN STOCKAGE INTERMEDIAIRE. L'INVENTION CONCERNE EGALEMENT UN DISPOSITIF COMPRENANT UN REACTEUR DE CHARGE ET DE MELANGE CONTINU 50, 51 DANS LEQUEL EST MONTE UN DISPOSITIF 57, 59 PERMETTANT D'OBTENIR UN FORT FROTTEMENT DES MATIERES CONTENUES A L'INTERIEUR. In a method for producing mixtures of thermoplastic synthetic materials and mineral or organic charge materials, the materials are vacuum mixed and compressed. According to the invention, the mixtures of synthetic materials and charge materials are already homogeneous in a powder state. They are also resistant without granulation to disaggregation, they are stable and can be shaped as products. Moreover, the rigidity must be obviously high but without fragility. The values of the resistance must approach those of the pure synthetic material. Finally, commercial advantages must be attained. To these purposes, the charge materials must be electrically or electrostatically charged before and/or during the mixing with the synthetic materials. As an alternative, this can also be achieved with the synthetic material and even, for instance, through a continuous stirring within an electric field. The charge remains stable during a long period allowing a previous treatment and a storage of the charge material separated from the mixing operation. A combined loading and mixing reactor, together with an installation (57) for producing a strong grinding of the content, is also part of the invention.
