  1. LUOGANYINSU

  排氣式螺桿多采用多階設計,此設計的優勢在于排氣口處為常壓,物料不致流出。有一個排氣口的擠出機廠家要求有 2 階螺桿,有 2 個排氣口需要 3 階螺桿。每 1 階有常壓段、壓縮段及計量段,第 1 階起始段為常壓加料段,第 2 階為常壓排氣段,也就是排氣口所在的位置。對于排氣式擠出機螺桿設計有 2 個主要的問題:第一,在到達排氣段時,物料必須全部熔融,以排出揮發份;第二,第 2 階螺桿的送料量必須大于第1階螺桿,以使第 2 階起始處螺槽未充滿,這樣就可使排氣口處保持常壓。當第 1 階螺桿的送料量比第 2 階螺桿大時,擠出機中的熔體就會發生倒流。要解此決此問題,就得減少第 1 階的送料量或增加第 2 階的送料量。

  排氣式螺桿是否冒料,與擠出工藝、塑料性能以及螺桿及排氣口的設計有直接的關系,所以擠出機廠家在使用排氣式擠出機進行生產加工時,要對加工工藝、樹脂特性以及設備性能作詳盡的了解,才能使排氣式擠出機正常穩定運行。
