| 摘要 | A method for producing particles, including: bringing a compressive fluid into contact with a pressure plastic material, so as to plasticize the pressure plastic material; applying a shear force to the compressive fluid and the plasticized pressure plastic material, between which an interface exists, in the presence of a surfactant to granulate the pressure plastic material in the compressive fluid, so as to produce particles. | ||

| 主权项 | 1. A method for producing particles, the method comprising: contacting a compressive fluid with a pressure plastic material to plasticize the pressure plastic material, thereby obtaining a plasticized pressure plastic material, and applying a shear force to the compressive fluid and the plasticized pressure plastic material, with an interface therebetween, in the presence of a surfactant to granulate the pressure plastic material in the compressive fluid and to produce particles. | ||
