Title
(EN) INTENSIVE MIXING TOOL FOR PRODUCING ELASTOMER-BASED COMPOSITES
(FR) OUTIL DE MÉLANGE INTENSIF POUR LA PRODUCTION DE COMPOSITES À BASE D'ÉLASTOMÈRE
Abstract
(EN)
A system is provided for producing an elastomer-filler masterbatch. The system includes an elastomer emulsion stored in a liquid phase in an emulsion reservoir; a slurry solution stored in a liquid phase in a slurry reservoir; and an intensive mixing tool (10) in fluid communication with each of the emulsion reservoir and the slurry reservoir. The intensive mixing tool includes a mixing unit (12) having a central body (14) and an injector inlet (22) that extends normally from each of a pair of opposed side surfaces (14c) of the central body such that at least a pair of injection inlets are located symmetrically and in opposing manner relative to a central axis of the central body. Each injector inlet establishes fluid communication between one of an elastomer emulsion reservoir and a slurry solution reservoir such that simultaneous injection of the elastomer emulsion and the slurry solution into the mixing chamber, each as a continuous flow under pressure, forms a vortex therein.

L'invention concerne un système pour produire un mélange maître d'élastomère-charge. Le système comprend une émulsion élastomère stockée dans une phase liquide dans un réservoir d'émulsion; une solution de suspension stockée dans une phase liquide dans un réservoir de suspension; et un outil de mélange intensif (10) en communication fluidique avec chacun du réservoir d'émulsion et du réservoir de suspension. L'outil de mélange intensif comprend une unité de mélange (12) ayant un corps central (14) et une entrée d'injecteur (22) qui s'étend normalement à partir de chacune d'une paire de surfaces latérales opposées (14c) du corps central de telle sorte qu'au moins une paire d'entrées d'injection sont situées symétriquement et de manière opposée par rapport à un axe central du corps central. Chaque entrée d'injecteur établit une communication fluidique entre un réservoir d'émulsion d'élastomère et un réservoir de solution de suspension de telle sorte que l'injection simultanée de l'émulsion d'élastomère et de la solution de suspension dans la chambre de mélange, chacune sous la forme d'un écoulement continu sous pression, forme un vortex à l'intérieur de celle-ci.
