Abstract

The invention relates to a two-way extrusion capillary rheometer. The rheometer comprises two charging barrels and a capillary which is arranged between the two charging barrels in a detachable manner, wherein one charging barrel is provided with a feeding device; two ends of the capillary are respectively communicated with the inner cavities of the two charging barrels; and a plunger which is matched with each charging barrel and used for extruding a material to be detected, and a drive system which is used for driving the plunger to move are arranged in each of the two charging barrels. According to the two-way extrusion capillary rheometer, the aim of multiple tests by once feeding can be achieved due to the structure that the two charging barrels are arranged at two ends of the capillary, so that the complicated physical labor can be simplified, the testing efficiency can be improved, materials can be saved, the work for cleaning charging barrels and capillary can be omitted; and tests for different materials to be tested can be implemented by selecting different capillaries to different materials to be tested.

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 rheological testing, in particular to a 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 years, i...
