Rotor-free vulcanizer real-Time Monitoring of Vulcanization Process
with Computer Controlled Rubber Testing Instruments
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.
Main performance features:
1. Vulcanization curve and upper and lower cavity temperature curve
can be printed at the same time;
2. Print data is complete, practical, can be stored, and has
statistical analysis function; (ML, MH, T10, T30, T50, T70, T90,
TS1, TS2, VC1, VC2, factory name, glue number, date, etc.)
3. Three main control technologies, leading position in China: (1)
Variable structure predictive control technology greatly improves
temperature control accuracy; Variable Structure Predictive Control
(VSPC) (2)Modular structure control technology to improve the
reliability and stability of the instrument; (3) The new structure
of torque measurement can eliminate all kinds of interference, keep
the curve smooth and improve the repeatability of data;
4. Test data can be exported for all kinds of researchers to write
papers.
Working principle:
Place the rubber sample into an almost completely enclosed mold
cavity and maintain it at the test temperature. The mold cavity has
two parts, the upper and lower parts, and the lower part undergoes
a small linear reciprocating motion (oscillation), which generates
shear strain on the sample. Measure the reaction force torque
(force) of the sample on the mold cavity, and the magnitude of the
torque (force) depends on the shear modulus of the adhesive. After
starting the vulcanization test, the shear modulus of the sample
increases, and the computer machine displays and records the torque
(force) in real time. When the torque (force) rises to a stable or
maximum value and returns to the state, the relationship curve
between torque (force) and time, namely the vulcanization curve, is
obtained. The shape of the curve is related to the test temperature
and the characteristics of the tape.
