■ Under the stable speed of a high precision gear pump, a small part of melt with a constant volume will form pressure difference within capillary in virtue of a special viscometer. The low shear rate, accurate dynamic viscosity and melt index of the melt can be calculated according to the specific calculation formula. The value can be set into intrinsic viscosity through correction factor and empirical data.
■ The 1stgeneration viscometer used for process control in the industry has been upgraded to the 3rd generation capillary on-line viscometer after constant practices, applications and innovations. Featured by high measurement accuracy (reading accuracy: ± 0.75%), excellent repeatability (± 0.2%), and simple and safe operation and maintenance, it can be maintained online without shutdown.
■ It is widely used in the online viscosity measurement of various high-molecular polymer industries, such as PET, PBT, PBAT and PC. In consideration of shear rate, capillary viscometer is much superior to vibrating viscometer in terms of high viscosity measurement.
