Title
(EN) SURFACE ENERGY MODIFIED PARTICLES, METHOD OF MAKING, AND USE THEREOF
(FR) PARTICULES MODIFIÉES PAR ÉNERGIE DE SURFACE, PROCÉDÉ DE FABRICATION ET LEUR UTILISATION
Abstract
(EN)
An apparatus and a process for modifying the surface energy of particles using a reactive gas or reactive energetic species generated in an excited and/or unstable gas stream is provided. The apparatus and process incorporates a process container, a portion of which is movable and having a shape in which the particles are tumbled during exposure to the energetic species. The resulting surface treatment allows the energy modified particles to be more easily dispersed in a liquid medium with a reduction in the occurrence of particle agglomeration or flocculation.
(FR)
L'invention concerne un appareil et un procédé pour modifier l'énergie de surface de particules à l'aide d'un gaz réactif ou d'une espèce énergétique réactive générée dans un flux de gaz excité et/ou instable. L'appareil et le procédé comprennent une cuve de traitement, dont une partie est mobile et ayant une forme dans laquelle les particules sont culbutées pendant l'exposition à l'espèce énergétique. Le traitement de surface résultant permet aux particules modifiées par énergie d'être plus facilement dispersées dans un milieu liquide avec une réduction de l'occurrence d'agglomération ou de floculation de particule.
