    • A production process for a long fiber-filled thermoplastic resin composition using an apparatus having an extruder with at least two raw material feeding ports and a resin impregnating bath at the tip of the extruder, comprising the steps of feeding a resin mixture to a first feeding port provided at an upstream position of the extruder, feeding alkaline earth metals to a second feeding port provided at a downstream position of the extruder, melt-kneading to a mixture, allowing the obtained molten resin mixture to flow into the resin impregnating bath, passing a continuous fiber bundle through the molten resin mixture in the resin impregnating bath to impregnate the continuous fiber bundle with the resin mixture.
    • 一种长纤维填充热塑性树脂组合物的生产方法,该方法使用具有至少两个原料供给口的挤出机和挤出机前端处的树脂浸渍浴的装置,包括以下步骤:将树脂混合物进料到第一进料 设置在挤出机的上游位置,将碱土金属供给到设置在挤出机下游位置的第二进料口,熔融捏合到混合物中,使得到的熔融树脂混合物流入树脂浸渍浴中,通过 通过树脂浸渍浴中的熔融树脂混合物连续纤维束,以用树脂混合物浸渍连续纤维束。
