橡胶塑料转矩流变仪  系统组成

计算机控制转矩流变仪由密炼转矩流变仪、挤出式毛细管流变仪、毛细管测试模头、数据采集测量系统、电子计算机、操作软件等部分组成。

橡胶塑料转矩流变仪  适用范围

转矩流变仪可以用来研究热塑性材料的热稳定性、剪切稳定性、流动和塑化行为，其最大特点是能在类似实际加工过程中连续准确可靠地对体系的流变性能进行测定，还可以完成热固性材料的固化特性测试。

橡塑材料在加工成型的过程中，几乎都要涉及其流动性。例如，在挤出、注模、吹膜、压延等工艺中，材料的流动行为都是十分重要的。材料的流动性不但影响加工行为，还会影响最终产品的力学性能。例如，分子取向对模塑产品，薄膜和纤维的力学性能都有很大影响。而分子取向的类型和程度主要是由加工过程中流动场的特点和材料的流动行为所决定。

system composition

The computer-controlled torque rheometer consists of a mixing torque rheometer, an extrusion capillary rheometer, a capillary testing die, a data acquisition and measurement system, an electronic computer, and operating software.

Applicable scope

The torque rheometer can be used to study the thermal stability, shear stability, flow and plasticization behavior of thermoplastic materials. Its biggest feature is that it can continuously, accurately and reliably measure the rheological properties of the system in similar actual processing processes, and can also complete the solidification characteristic testing of thermosetting materials.

In the process of processing and forming rubber and plastic materials, their fluidity is almost always involved. For example, in processes such as extrusion, injection molding, blow molding, and rolling, the flow behavior of materials is very important. The fluidity of materials not only affects processing behavior, but also affects the mechanical properties of the final product. For example, molecular orientation has a significant impact on the mechanical properties of molded products, films, and fibers. The type and degree of molecular orientation are mainly determined by the characteristics of the flow field during the processing and the flow behavior of the material.

application area

1. Research on Processing Performance and Material Development of UPVC

2. Development and Processing Performance Research of Thermoplastic Materials

3. Research on the Curing Performance of Crosslinked and Thermosetting Resins

4. Teaching and research applications

It can be widely used in scientific research and production, and is an important instrument for conducting scientific research and guiding production. Compared with the general instrument for studying material flowability - viscometer, this rheometer provides a dynamic measurement method that is closer to actual processing. It can continuously, accurately and reliably measure the rheological properties of materials in situations similar to actual processing, such as the mixing of multi-component materials, crosslinking and curing of thermosetting resins, and vulcanization of elastomers, The dynamic stability of materials and the influence of screw speed on the processing performance of the system.

Internal mixing torque rheometer:

The internal mixing torque rheometer mainly consists of imported servo motors, high-precision dynamic torque sensors, gearboxes, mixing chambers, temperature modules, measurement modules, computers, measurement and control software, and other parts.

A closed mixer is equivalent to a small internal mixer, consisting of an infinity shaped detachable mixing chamber and a pair of rotors rotating in opposite directions at different speeds. In the mixing chamber, the rotor rotates in opposite directions and applies shear to the material, forcing it to be mixed in the mixing chamber; The two rotors have different speeds and exhibit dispersed mixing in their gaps.

The overall appearance of this machine is beautiful, and the main sheet metal adopts a color scheme of milky white and blue, which can also be processed according to the user's requirements. The stainless steel part adopts SUS304 stainless steel.

Computer software has functions for data collection, storage, calculation, analysis, and output, and can print test reports according to user requirements.
