Apparatus and a method is disclosed for treating particulate materials (e.g., plastic resins) so as change the surface characteristics of the particulate materials comprising a work chamber receiving a quantity of the particulate material to be treated, a power supply, and a capacitor energized by the power supply, where the capacitor generates a capacitive plasma which is used to treat the particulate material such that when objects are formed from the treated particulate material, such objects will have enhanced surface characteristics. Further, a quantity of a gas may be introduced within the work chamber to facilitate the generation of a plasma within the particulate material.
l'invention concerne un dispositif et un procédé de traitement de matériaux particulaires (tels que des résines plastiques) destiné à modifier les caractéristiques de surface de ces matériaux. Ce dispositif comprend une chambre de travail recevant une quantité de matériau particulaire à traiter, un source d'énergie et un condensateur qui, soumis à l'excitation de la source d'énergie, génère un plasma capacitif. Ce plasma sert à traiter le matériau particulaire afin que les objets formés présentent des caractéristiques superficielles améliorées. On peut aussi introduire une certain volume de gaz dans la chambre de travail pour faciliter la génération de plasma à l'intérieur du matériau particulaire.
