Rotor-free vulcanizer real-Time Monitoring of Vulcanization Process with Computer Controlled Rubber Testing Instruments
Features and uses:
Rotor-free vulcanizing instrument is the most widely used instrument in rubber processing industry to control rubber quality, rapid inspection and rubber basic research. It provides accurate data for the rubber optimization formula combination, and can accurately measure the burning time, positive canation time, vulcanization index, maximum and minimum torque and other parameters. The vulcanizer includes: host, computer, temperature measurement, temperature control, data acquisition and processing, sensor and electrical chain and other parts. The measurement and temperature control circuit is composed of measurement and control module, platinum resistance and heater, which can automatically track the change of power grid and environmental temperature, automatically correct the PID parameters, to achieve the purpose of fast and accurate temperature control. The data acquisition system and the electromechanical linkage complete the automatic detection of the torque signal in the rubber vulcanization process, and the automatic real-time display of the temperature value and setting value. After vulcanization, automatic processing, automatic calculation and printing of vulcanization curve and process parameters. Show vulcanation time, vulcanation moment. The computer shows the vulcanization process in real time, and you can see the change of the "temperature" and the "time-torque" change process at a glance from the above.
Working principle:
The rubber sample into the almost completely closed mold cavity, and keep in the test temperature, the mold chamber has upper and lower two parts, the lower part with small linear reciprocating movement (oscillation), oscillation makes the sample produce shear strain, determination of the sample on the mold cavity reaction torque (force), the size of the torque (force) depends on the shear modulus of the glue. After the start of the vulcanization test sample shear modulus increases, the computer machine display and record the torque (force) in real time, when the torque (force) rise to the stable value or the maximum and return state, then get a torque (force) and time relationship curve, namely vulcanization curve, the shape of the curve and the test temperature and the characteristics of the tape.
