    • A method and system are provided that efficiently compound high levels of inorganic filler, processing fluid and silicone polymer at a commercial rate into homogeneous filled and devolatilized silicone compositions. In the method, filled silicone compositions are compounded by compounding a filler, processing fluid and silicone polymer in a first compounding apparatus to produce a first dispersed composition and simultaneously compounding a filler, processing fluid and silicone polymer in a second compounding apparatus that shares a common extruder shaft with the first compounding apparatus to produce a second dispersed composition. The system comprises a first compounding apparatus and a sequential second compounding apparatus that shares a common shaft with the first compounding apparatus. An extruder transition section of the system includes an enclosed discharge chamber defined by a first sectioning wall, a second sectioning wall and a contoured lower wall that transitions toward a discharge port and a shaft extends through the first sectioning wall, traverses the chamber and extends through the second sectioning wall.
    • 提供了一种方法和系统,其以商业速率有效地将高含量的无机填料,加工流体和硅氧烷聚合物复合到均匀的填充和脱挥发份的硅氧烷组合物中。 在该方法中,填充的硅氧烷组合物通过在第一配混装置中混合填料,加工流体和硅氧烷聚合物来混合,以制备第一分散组合物,并且在共享共同的第二配混装置中同时混合填料,加工液和硅氧烷聚合物 挤出机轴与第一配混设备产生第二分散组合物。 该系统包括与第一混合装置共用公共轴的第一混合装置和顺序第二混合装置。 系统的挤出机过渡部分包括由第一分段壁,第二分段壁和轮廓下壁限定的封闭排放室,该下壁朝向排放口转变,并且轴延伸穿过第一分段壁,穿过室并延伸穿过 第二分段墙。
