Title
(EN) Method of carrying out continuous preparation process on tightly meshing extruders rotating in the same sense
(ZH) 在同向旋转的紧密啮合式挤压机上实施连续制备过程的方法
Abstract
(EN)
In a method of carrying out continuous preparation processes on tightly meshing extruders rotating in the same sense such as twin-screw and multi-shaft screw-type extruders, the extruder is operated at a screw speed of rotation of at least 800 rpm, accompanied with a simultaneous increase of the so-called 'torque density'(Md/a3) of at least 11 Nm/cm3 and a volumetric ratio (Da/Di) of at least 1.5.

(ZH)

本发明涉及一种在同向旋转的紧密啮合式挤压机如双螺旋和多轴螺旋式挤压机上实施连续制备过程的方法,挤压机在螺旋转速为至少800rpm的条件下运行,与此同时提高可引入的所谓“扭矩密度”(Md/a3)为至少11Nm/cm3和体积比(Da/Di)为至少1.5。
