Abstract

The present invention relates to a vertical bidirectional extrusion capillary tube rheometer, which comprises two material cylinders and a capillary tube detachably arranged between the two material cylinders, wherein one material cylinder is provided with a feeding device, both ends of the capillary tube are respectively communicated with inner cavities of the two material cylinders, and plungers matched with the material cylinder and provided for extruding a measured material and drive systems for driving the plunger to move are respectively arranged inside the two material cylinders. According to the vertical bidirectional extrusion capillary tube rheometer, the two material cylinders are arranged on both ends of the capillary tube so as to achieve a purpose of multiple tests through one time feeding, simplify tedious physical labor, improve test efficiency, saving the material, and eliminates works of material cylinder cleaning and capillary tube cleaning. In addition, with the present invention, different capillary tubes can be selected based on different measured materials so as to achieve tests on different measured materials.

Description

[0001] This application is a divisional application with application number "2011104439315", application date: 2011.12.27, and invention name "bidirectional extrusion capillary rheometer and parallel bidirectional extrusion capillary rheometer". technical field [0002] The invention relates to the technical field of rheology testing, in particular to a vertical bidirectional extrusion capillary rheometer. Background technique [0003] Capillary rheometer can be used to measure the fluidity and solidification speed of thermosetting materials, draw the stress change curve and plasticizing curve of thermoplastic materials, and measure the temperature of softening point, melting point and flow point. It can measure the viscosity and viscous flow activation of polymer melt, and also study the process conditions of melt spinning. The traditional capillary rheometer, whether it is a single-tube capillary rheometer or a double-tube capillary rheometer that has appeared in recent ye...
