| description | To make pellets with a low defect rate by cutting heat resistant thermoplastic.SOLUTION: Heat-resistant thermoplastic resin is heated above its glass transition temperature to a molten state and extruded through a die having a plurality of pores, and method for producing pellets of heat-resistant thermoplastic resin, comprising a cutting process in which the heat-resistant thermoplastic resin in a molten state extruded from the pores is cut by a plurality of rotating blades and fed into cooling water. The rotating blades are formed from steel having a Rockwell hardness (HRC) of 62 or greater. The width of the die contact surface of the cutting edge in the rotary blade is between 0.2 mm and 1.0 mm.SELECTED DRAWING: Figure 3
【課題】耐熱性熱可塑性樹脂を低い不良率でカットしてペレットにする。【解決手段】耐熱性熱可塑性樹脂をガラス転移温度以上に加熱して溶融状態とし、複数個の細孔を有するダイスから押し出す工程と、前記細孔から押し出された溶融状態の前記耐熱性熱可塑性樹脂を複数の回転刃で切断し、冷却水に投入する切断工程とを有する耐熱性熱可塑性樹脂ペレットを製造する方法であり、前記回転刃がロックウェル硬さ（ＨＲＣ）が６２以上である鋼材から形成されるものであり、前記回転刃における刃部のダイス接触面の幅が０．２ｍｍ以上１．０ｍｍ以下である。【選択図】図３ |
