Title
(EN) COMPOUNDING EXTRUDER FOR PRODUCING POLYPROPYLENE COMPOSITION
(FR) EXTRUDEUSE DE COMPOUNDAGE POUR LA PRODUCTION D'UNE COMPOSITION DE POLYPROPYLÈNE
Abstract
(EN) Compounding extruder for producing a propylene-based polymer composition, comprising a) a melting section (100) comprising ai) a first elongated cylindrical tube having an end portion having a first inlet port (101) and an end portion having a first outlet port (102), and aii) a first screw arranged in the first elongated cylindrical tube and having a first length L1, a first outer screw diameter Do1 and a first inner screw diameter Di1, b) a mixing section (200) comprising bi) a second elongated cylindrical tube having an end portion having a second inlet port (201), an end portion having a second outlet port (202) and a side inlet port (204, 205, 206) between the second inlet port and the second outlet port, and bii) a second screw arranged in the second elongated cylindrical tube and having a second length L2, a second outer screw diameter Do2 and a second inner screw diameter Di2, wherein the first screw and the second screw are operable at different screw speeds, wherein Do1 is 0.82 to 1.2 x Do2.
(FR) L'invention concerne une extrudeuse de compoundage pour la production d'une composition de polymère à base de propylène, comprenant a) une section de fusion (100) comprenant ai) un premier tube cylindrique allongé ayant une partie d'extrémité ayant un premier orifice d'entrée (101) et une partie d'extrémité ayant un premier orifice de sortie (102) et aii) une première vis disposée dans le premier tube cylindrique allongé et ayant une première longueur L1, un premier diamètre de vis externe Do1 et un premier diamètre de vis interne Di1, b) une section de mélange (200) comprenant bi) un second tube cylindrique allongé ayant une partie d'extrémité ayant un second orifice d'entrée (201), une partie d'extrémité ayant un second orifice de sortie (202) et un orifice d'entrée latéral (204, 205, 206) entre le second orifice d'entrée et le second orifice de sortie, et bii) une seconde vis disposée dans le second tube cylindrique allongé et ayant une seconde longueur L2, un second diamètre de vis externe Do2 et un second diamètre de vis interne Di2, la première vis et la seconde vis pouvant fonctionner à des vitesses de vis différentes, Do1 étant de 0,82 à 1,2 x Do2.
