Title (EN) MILL MIXING PROCESS FOR COMPOUNDING GAS-PHASE PRODUCED ELASTOMERS
(FR) PROCEDE DE MELANGE EN LAMINOIR POUR L'ELABORATION EN PHASE GAZEUSE D'ELASTOMERES MELANGES
Abstract:
(EN) There is provided a preferred process for continuous mill mixing which comprises: (i) blending a gas-phase produced elastomer and one or more other compounding ingredients in a dry blender (distributive mixing), (ii) feeding the blend to an open roll mill for compounding into sheets or strips (dispersive mixing). A vulcanizing system can be introduced in either the dry blending (i) or mill mixing compounding (ii) step, but is preferably introduced during dry blending.
(FR) L'invention concerne un procédé préféré pour le mélange en laminoir continu, qui consiste (i) à mélanger un élastomère élaboré en phase gazeuse et un ou plusieurs autres éléments de mélange dans une machine à extrusion dry blend (mélange par distribution), (ii) à fournir le mélange à un mélangeur ouvert pour l'élaboration de feuilles ou de bandes (mélange par dispersion). On peut introduire un système de vulcanisation au stade de l'extrusion dry blend (i) ou du mélange en laminoir (ii), mais ledit système est introduit de préférence au stade de l'extrusion dry blend.
