Rheometers have been widely used in many industries such as chemical industry, materials, pharmaceuticals, food, new energy, etc. They can be used to study the flow and deformation of samples. They are applicable from fluids to soft solid materials. They are used in material selection, product performance evaluation and quality Improvements and other aspects can provide important information; commonly used to measure viscosity-temperature curve, flow curve, creep recovery curve, yield stress, thixotropy, viscoelasticity, storage modulus, loss modulus, loss factor, etc. It is a new product development , A good tool for performance prediction, process optimization and quality control.
The rheometer is generally composed of four parts: measuring head, temperature control system, rotor system, and data acquisition and processing system. The rotor system is an important part of the rheometer, and the choice of the rotor is very important for practical applications. The rotor of the rheometer can be roughly divided into six categories: coaxial cylindrical rotor, parallel plate rotor, flat cone plate rotor, blade rotor, throwable rotor and other rotor systems.
Before we actually test the rheometer, we must not only consider the viscosity range, volatility, uniformity, particle size, amount of the sample to be tested, and whether it is easy to slip and other properties of the sample, but we must also consider more sample characteristics and project test requirements. Perform detailed understanding, comprehensively consider all influencing factors, and select a suitable rotor for corresponding testing, thereby greatly improving the efficiency and accuracy of rheological testing.
