Well designed high quality mdr moving die rheometer

Summary:

Moving Die Rubber 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:

Moving Die Rheometer used monolithic rotor control, which include: host, temperature measurement, temperature control, data acquisition and processing, sensors and electrical chains and other components. These measurements, temperature control circuit consists of a temperature control device, platinum resistance, heater composition, capable of automatic tracking power and ambient temperature changes, automatically correct PID parameters to achieve fast and accurate temperature control purposes. Data acquisition system and mechanical linkage to complete the rubber vulcanization process of force torch signal automatic detection, automatic real-time display of temperature and settings. After curing, automatic processing, automatic calculation, print vulcanization curve and process parameters. Show curing time, curing power Ju, also has a variety of audible alert. 

DZ-321-type non-rotor curing equipment 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.
