Abstract

Introducción de aditivos en una corriente lateral de un flujo de polímero fundido, tiene lugar en una bomba de engranajes planetario, conlleva un flujo de corte hacia los piñones exteriores completando externamente la dispersión con un mezclador estático, antes de reintroducirse en el flujo principal. Toda la corriente lateral abstraída, (2), o dividida en como mucho (n-1) corrientes laterales (2a-c), se entrega directamente a como mucho (n-1) de los piñones (3a-c) de una bomba de engranajes planetarios (3) con n piñones (3a-d). Simultáneamente, se suministran aditivos sin mezclar (4) directamente a otro, piñón n.º (3d). La corriente lateral, ahora mezclada con aditivos abandona la bomba desde el centro, para ser introducida en la corriente principal de polímetro fundido. Características preferidas: n es 3-8. La corriente lateral pasa a través de un mezclador estático (6) antes de ser reintroducido en la corriente principal. Los aditivos no añadidos son suministrados centralmente en una entrada de la bomba.
