Rubber Rheometer Moving Die Rheometer

 Rubber Rheometer Moving Die Rheometer

Summary:

Rubber Rheometer Moving Die Rheometer widely used in rubber processing industry, rubber quality control and basic research rubber, For optimize formula of rubber provide accurate data, It can accurately measure the scorch time, rheometer time, sulfide index, the maximum and minimum torque and other parameters.

Main functions:

The Rubber Rheometer Moving Die Rheometer measures the change in stiffness of a rubber sample. The sample is compressed between two heated platens and by an applied oscillating force. The degree of vulcanization determines the cure characteristic of the sample as it is heated and compressed. Our Moving Die Rheometer offers affordable testing and stunning results. We offer sealed die and un-sealed die type configurations to suite your application. The Servo driven system provides extremely steady oscillation frequencies as well as low noise to ensure test accuracy, convenience and increased lifespan of the machine. Operated with a remote computer via RS-232, we can analyze results taking data at 100,000 readings per second. The machine allows for selectable times and torques during setup or in testing to accommodate limitless configurations. You can monitor the test from the computer or large LCD displays on the front for in test evaluation. The design features Modular internal parts for in house servicing and overall easy maintenance.
DZ-321 Rubber Rheometer Moving Die Rheometer controlled by computer, the computer setting the parameters of the direct control of test parameters rheometer. Display real-vulcanization curve and temperature curve, store test results, different adjustable comparison of test results and in a different color.

Applicable Industries: 

Moving Die Rheometer widely used in rubber industries.

Work Principle:

The rubber sample into the mold cavity is almost entirely enclosed and maintained at test temperature.

the mold cavity are of two parts, of which the lower part with a small linear reciprocating movement (swing oscillation), oscillatory shear specimen produced strain determination is the reaction torque of the mold

cavity (force), this torque (force) depends on the shear modulus of rubber.

Curing test  specimens after the start of the shear modulus increases, the computer machine real-time

display and record the torque (force), when the torque (force) rose to a stable value or the maximum

as well as return to the state, they get a torque ( force) and time curve, that is, curing curve (Figure 1),

shape of the curve and test the temperature and plastic material characteristics.
