Abstract

Procedimiento para el mezclado continuo, homogéneo de poliolefina en polvo, con aditivos, caracterizado porque se mezcla el polvo y los aditivos con una potencia de 370 hasta 1.280 Wh/m3, preferentemente de 400 hasta 500 Wh/m3 de polvo por medio de cuchillas rotatorias con una frecuencia de sucesión de cuchillas de 100 hasta 300 por segundo, preferentemente de 250 hasta 300 por segundo y en tal caso se conduce el polvo a través de una zona con una densidad de disipación de energía de 200 hasta 350 W/litro de volumen de mezclador.
