Closed Type Rotorless Rheometer (open Mode)

This machine is suitable for analyzing and measuring the performance indicators of rubber vulcanization process, such as scorch time, positive vulcanization time, vulcanization rate, viscoelasticity, and vulcanization flatness period. It is one of the key testing instruments used in the rubber industry for developing new products, researching rubber formula, and inspecting product quality When testing with a vulcanizer, place the rubber sample in a closed, pressurized container, and oscillate the lower mold with a sine wave to apply strain to the sample; The upper mold is connected to a sensor that reflects torque to measure torque. Our company's production adopts the principle of a servo driven eccentric wheel, which drives the lower mold to oscillate at a fixed frequency and angle. The upper mold is connected to a torque element to measure the torque during the motor oscillation process. The amplifier collects and processes raw data, correctly decomposes the full torque, and obtains characteristic parameters such as rubber viscosity, elasticity, and viscoelasticity ratio.
