Abstract: front page image
(EN)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.
(FR)Dans un procede pour la fabrication de melanges de matieres synthetiques thermoplastiques et de matieres de charge minerales ou organiques, les matieres sont melangees sous vide et comprimees. Selon l"invention, les melanges de matieres synthetiques et de matieres de charge sont deja homogenes dans un etat pulverulent. Ils sont aussi resistants sans granulation a la desagregation, stables et faconnables en produits. En outre, la rigidite doit etre manifestement elevee mais sans fragilite. Les valeurs de la resistance doivent approcher celles de la matiere synthetique pure. Finalement, les avantages commerciaux doivent etre atteints. A ces fins, les matieres de charge doivent etre chargees electriquement ou electrostatiquement avant et/ou pendant le melange avec les matieres synthetiques. Dans une variante, cela peut aussi etre realise avec les matieres synthetiques et meme, par exemple, par un brassage continu dans un champ electrique. La charge reste stable pendant une longue periode ce qui permet un traitement prealable et un entreposage de la matiere de charge separes de l"operation de melange. Un reacteur combine de charge et de melange, avec une installation (57) pour produire un broyage energique du contenu, fait aussi partie de l"invention.
