通过对普通螺杆和低剪切螺杆在不同的机头压力和螺杆转速下的对比试验得出,在胶料粘度较低时,螺杆转速和胶料种类是影响低剪切螺杆挤出功率的重要因素。在同一条件下,低剪切螺杆的挤出温度高于普通螺杆,机头压力低于普通螺杆,从而进一步了解了低剪切螺杆的塑化和混合性能,为螺杆的设计参数的确定提供了依据。
Through comparing the normal screw and low shear screw under different head pressure and screw speed, it is found that screw speed and compound type are important factors to influence the low shear screw extrusion power when the viscosity of compound is low. factor. Under the same conditions, the extrusion temperature of the low-shear screw is higher than that of the ordinary screw, and the head pressure is lower than that of the ordinary screw, thereby further understanding the plasticization and mixing performance of the low-shear screw and providing the design parameters of the screw in accordance with.
