摘要:
针对目前高分子原料粘度测量的常规方法，如细管法、旋转法和平板法等不能实现高分子材料成型过程中熔体粘度在线检测的难题，提出了一种在微型锥形双螺杆挤出机上检测高分子原料粘度的新方法：在微型锥形双螺杆挤出机的特定段设计一个导程的全啮合区，通过该啮合区的C形腔室容积而获得原料的流量这一重要的参数.同时，设置一回程直圆流道并在其上安置压力和温度传感器从而获得流经该流道的压力差.最后，根据非牛顿流体的力学原理和获得的相关数据即可计算出流经该流道的高分子原料的粘度.与目前常用的其他检测方法比较，该方法可以实现高分子原料在成型过程中的在线检测.
Abstract:
A new method of detecting viscosity of the polymer materials with miniature conical twin screw extruder was investigated. The new method was achieved by the following three steps: Firstly,volume of the Cshaped chamber was ascertained by setting a full engagement region in one miniature conical twin screw extruder during one lead. and flow rate was obtained by the volume of the Cshaped chamber and other known parameters. Secondly, one backhaul cylindrical channel was set inside the miniature conical twin screw extruder .Pressure difference and temperature of the backhaul cylindrical channel were detected with corresponding sensors. Thirdly, the viscosity of the polymer materials was worked out as per RobinowichMooney equation and all known parameters .Compared with the present traditional methods of detecting viscosity of the polymer materials,online detecting can be achieved merely by the new method.
