Overview

1.1Product Features

During the processing and molding of rubber and plastic materials, their flowability is almost always involved. For example, in processes such as extrusion, injection molding, blown film, and rolling, the flow behavior of materials is crucial. 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 and the flow behavior of the material during the processing.

image1 Internal torque rheometer

A closed mixer is equivalent to a small internal mixer, consisting of a The detachable mixing chamber in the shape of an "∞" and a pair of rotors rotating in opposite directions at different speeds. In the mixing chamber, the rotors rotate in opposite directions, applying shear to the materials and forcing them to mix in the mixing chamber; The two rotors have different speeds, resulting in 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 color requirements. The stainless steel part adoptsSUS304stainless steel.

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

ØExtrusion capillary rheometer:

The extrusion capillary rheometer is mainly composed of 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 that through the rotation of the screw, the animal material is carried throughoral modelExtrusion is the process of measuring the shear rate and shear pressure of a material, and calculating the viscosity of the material at a specified temperature. simultaneouslyThe 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 and processing, various methods such as controlling extrusion speed, melt temperature, and formula ratio are used to verify the production process.

The core part of an extrusion capillary rheometer is a set of delicate capillaries with different aspect ratios (usuallyL/D =10/1，20/1，30/1，40/1By conducting comparative experiments with different aspect ratios of mouth molds (keeping other conditions constant, such as temperature, etc.), different pressure values were obtained, and the viscosity of the material was calculated.

This device is equipped with screws of different parameters that rotate inside a cylinder with a certain temperature, and a feeding hopper is located at the other end of the cylinder. When the raw materials are sent to the cylinder2/3The material gradually plasticizes and is homogenized in the remaining part of the cylinder. When all particles are melted, it can be extruded into a mother material using a capillary extrusion mold or injected into a mold for forming. At the same time, the equipment also measures the relationship between the material's apparent viscosity, shear rate, and shear stress.
