双螺杆挤出机组主要应用于橡塑和工程树脂的填充、共混、改性、增强、氯化聚丙稀和高吸水性树脂的脱挥处理；可降解母粒、聚酰胺缩聚、聚氨酯加聚反应的挤出，碳粉、磁粉的造粒、电缆用绝缘料、护套料、低烟低卤阻燃型PVC电缆料及各种硅烷交联料的制备等。

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。

本设备配有不同参数的螺杆，在具有一定温度的圆筒内旋转，筒的另端设有送料斗。当原料被送至筒的2/3处时逐步增塑，进入到筒的剩余部分内被均化，当所有颗粒全部溶化后即可利用毛细管挤出模具成为母料或注入模具成形，同时设备也完成对材料的表现粘度与剪切速度及剪切应力关系的测量。

挤出机可以根据不同的物料特性选择不同类型的螺杆，螺杆的压缩比不同，对物料的试验性能有很大的影响。螺杆可以方便的互换，以支持对不同物料的快速试验。

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。

挤出式毛细管流变仪主要由进口伺服电机、减速器、挤出螺杆、口模、测控模块、温度模块、压力传感器、电子计算机及测控软件组成。其原理是经由螺杆的旋转，带动物料经由口模挤出，在这个过程中测量材料的剪切速率和剪切压力，计算机物料在规定温度下的粘度。同时，挤出式毛细管流变仪也可以做为生产工艺测验的仪器，通过更换不同类型的口模，以少量物料进行实际的生产加工，在这个过程中通过控制挤出速度、熔体温度、配方比例等多种手段，对生产工艺进行验证。

A torque rheometer is an ideal device for studying the flow and deformation, plasticization, thermal shear stability, dynamic rheological properties, and plasticization behavior of polymer materials, and presenting the results in graphical forms such as torque time and torque temperature.

The twin-screw extruder unit is mainly used for filling, blending, modifying, strengthening rubber and engineering resins, as well as devolatilization treatment of chlorinated polypropylene and high water absorbent resins; The extrusion of biodegradable masterbatch, polyamide condensation polymerization, polyurethane addition polymerization reaction, granulation of carbon powder and magnetic powder, preparation of insulation materials for cables, sheath materials, low smoke and low halogen flame retardant PVC cable materials, and various silane crosslinking materials.

It 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 curing characteristic testing of thermosetting materials.

This device is equipped with screws with different parameters, which rotate inside a cylinder with a certain temperature, and there is a feeding hopper at the other end of the cylinder. When the raw materials are sent to 2/3 of the barrel, they gradually plasticize and enter the remaining part of the barrel for homogenization. After all particles dissolve, they can be extruded into the master material using capillary tubes or injected into the mold for forming. At the same time, the equipment also completes the measurement of the relationship between the apparent viscosity of the material, shear rate, and shear stress.

The extruder can select different types of screws based on the characteristics of different materials, and the compression ratio of the screws varies, which has a significant impact on the experimental performance of the materials. The screws can be easily interchanged to support rapid testing of different 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.

The extrusion capillary rheometer mainly consists of an imported servo motor, reducer, extrusion screw, die, measurement and control module, temperature module, pressure sensor, electronic computer, and measurement and control software. The principle is to rotate the screw and extrude the animal material through the mouth mold. During this process, the shear rate and shear pressure of the material are measured, and the viscosity of the material at the specified temperature is calculated. At the same time, the extrusion capillary rheometer can also be used as an instrument for production process testing. By replacing different types of molds and using a small amount of material for actual production processing, various methods such as controlling extrusion speed, melt temperature, and formula ratio are used to verify the production process.北广精仪公司电性能及橡胶塑料相关产品：
