The performance of the viscometer mainly includes the following aspects:
Measurement accuracy and repeatability: The measurement accuracy of the viscometer can usually reach 0.01mPa.S, and it has good repeatability, which can ensure the stability and reliability of the test results.
Ease of operation: The viscometer is simple in design, the operation steps are easy to master, and no complicated sample preparation is required. It is suitable for various types of fluids, such as oil, juice, resin and adhesive, etc.
Data recording and analysis function: Modern viscometers are usually equipped with data recording and analysis software, which can record the changes of viscosity over time, speed or rotor, and temperature in real time, which helps to gain a deeper understanding of the rheological properties of the fluid.
Temperature control: The viscometer is usually equipped with a temperature probe, which can monitor the sample temperature in real time, ensure that the test is carried out at a constant temperature, and improve the test accuracy.
Scope of application: The viscometer is suitable for various types of fluids, including Newtonian fluids and non-Newtonian fluids. Although the Mooney viscometer is mainly suitable for polymer materials such as rubber and plastic, it is easy to operate, fast to test and has good reproducibility of results.
Working principle of viscometer: The viscometer calculates the viscosity of the fluid by measuring the speed at which the fluid passes through a standard viscosity hole. The speed at which the fluid passes through the hole is related to the viscosity of the fluid, so the viscosity is calculated by measuring the time required for the fluid to pass through the hole.
Performance differences between different types of viscometers: For example, the digital viscometer has a humanized and personalized design, supports 7500 stepless shear rate settings, and can simultaneously display multiple parameters such as shear stress, shear rate, speed, viscosity, time and temperature.
The laboratory viscometer uses a unique viscosity probe design to measure the absolute viscosity value of the fluid using magnetic field suspension motion, and has the characteristics of high precision and high-frequency reciprocating motion.
