Dynisco REX 挤出流变仪

仪器简介：
Dynisco REX流变挤出系统的设计可在一个加工过程中连续取样式（样品可为高分子粉料、片板、颗粒等），并且传送到小型挤出机，再进行流变测试。此系统可连续检测高分子熔体流动速率和粘性，也可进行其他分析，以达到质量和加工控制的目的。

Rheological Analyzers

All DYNISCO Polymer test on-line rheometer with their features are connectable
CMR III (one capillary)
FCR (two capillaries)

主要特点：
1. Parctical for multiple on-line analyses. (Rheology, composition, contamination)
2. Can be installed on the manufacturing floor or outside of the production area
3. Automated pneumatic transfer of samples to conditioning extruder
4. Fast response time for process control applications
5. Simple calibration
6. Sample is tested as the "customer" will test it (pellet form, secondary melt)
7. Data input/output communication to a distributed control system (DCS) via digital or analog signals
