RM-200C挤塑式转矩流变仪

实验室单螺杆挤出机由测控主机和单螺杆挤出平台组成，根据加工物料的不同多种结构、直径、长径比、压缩比的螺杆可选，在实验室环境下进行多种功能性实验。配不同模具及其他辅机设备可实现模拟挤条、挤片、挤管、压延、流延、吹膜等加工过程，从而评价物料的加工性能以及优化加工工艺参数。

Laboratory Single Screw Extruder can be integrated by main unit and single screw extrusion unit. The screw with different structure,diameter, length-diameter radio and compress ratio can be chosen depending on the sample material. Integrating different extruding dies and other auxiliary equipment, the system could simulate many functional experiments in the laboratory.

配以毛细管模具，挤出系统可以像其他毛细管流变仪一样测定一定范围内剪切速率下的熔体粘度，用挤出机测量熔体压力的优点是更真实地模仿了材料的挤出过程。通过改变挤出机转速和更换不同长径比模芯，获得不同转速下的熔体流量和入口压力，并通过软件（HPVisco1.2）进行口模校正和非线性校正，可获得剪切速率和粘度的关系。

Equipped with capillary dies, the extrusion unit could be used to measure the melt viscosity over a usual shear rate range. This so called extruding capillary Rheometer could obtain the viscosity information closed to extruding process. The melt flow and die pressure can be obtained under different rotation speed, by changing the screw speed and die cores with different length-diameter ratio, the relation between shear rate and melt viscosity can be calculated with software after dies entrance pressure calibration and nonlinear calibration.
