What is a Capillary rheometer?
A capillary rheometer is a device used to evaluate the viscosity characteristics of fluids, particularly for measuring the flow properties of polymer materials and plastics. This device operates by extruding the fluid through a narrow capillary tube and measuring the pressure and flow rate. The testing procedure is as follows:
First, the sample is loaded into the cylinder and heated to a specified temperature. Then, a piston is used to extrude the fluid through the capillary tube at a constant speed or pressure. By measuring the pressure difference between the inlet and outlet of the capillary tube and the amount of fluid that flows, the viscosity and flow properties of the fluid can be calculated. The main feature of a capillary rheometer is its ability to perform high-precision measurements over a wide range of shear rates. This allows for detailed analysis of the non-Newtonian flow properties of the fluid, providing information such as shear viscosity, dynamic viscosity, and viscoelastic properties.
Capillary rheometers are used in a wide range of industries, including plastics, polymers, food, cosmetics, and pharmaceuticals. They play a crucial role in material processing and quality control of final products. Capillary rheometers are essential tools for evaluating material performance and developing new materials.
Application of Capillary rheometer
A capillary leometer is a device used to evaluate fluid substances. Since it can be heated to a high temperature, it is also used for evaluation of plastics that are solid at room temperature. Capillary leometer is a device for rheology evaluation Capillary leometers can evaluate rheological properties related to viscosity, external pressure, and fluidity when temperature is applied. Solid samples, such as plastic, are first heated in the device until they become liquid. The heated sample is then sent to a thin tube called a capillary and extruded at various speeds. The capillary leometer measures the melt viscosity for this extruded speed. It is used in the plastic industry because it can evaluate the viscosity when heated to a high temperature.
