Rubber Moving Die Rheometer

. Equipment overview:

Rotorless vulcanization instrument is the most widely used instrument in rubber processing industry to control rubber quality, rapid inspection and rubber basic research, which provides accurate data for rubber optimization formula combination, and can accurately measure the scorch time, positive vulcanization instrument time, vulcanization index and maximum and minimum torque parameters.

2. Main features:

1, no rotor vulcanization instrument adopts the latest version of the most advanced software, with fast heating (within 3 minutes), high temperature control accuracy.

2, no rotor vulcanization instrument adopts alpha closed mold cavity structure, in the international leading position.

3, no rotor vulcanization instrument adopts advanced alpha force sensor technology: (sensor accuracy up to 0.001N.m)

4, no rotor vulcanization instrument adopts advanced alpha closed cavity structure, the rotating cavity and the fixed cavity are closed through the imported sealing ring, and the structure of the closed cavity and the general open cavity is completely different, and its accuracy and requirements and advancement are not comparable. Closed cavity repeatability is completely consistent, in the international leading position.

Working principle:

The rubber sample is put into an almost completely closed mold cavity and kept at the test temperature. The mold cavity has two parts, the lower part moves in a small linear reciprocating motion (oscillating oscillation), and the oscillation causes the sample to produce shear strain. The reaction torque (force) of the sample to the mold cavity is determined.

After the vulcanization test begins, the shear modulus of the sample increases, and the computer displays and records the torque (force) in real time. When the torque (force) rises to the stable value or maximum value or even the return state, a curve of the relationship between torque (force) and time is obtained, that is, the vulcanization curve (Figure 1). The shape of the curve is related to the temperature of the test and the characteristics of the rubber material.

4. Standards:

The rotor-free vulcanization test instrument meets the requirements of GB/T16584 "Rubber - Determination of vulcanization characteristics with rotor-free vulcanization instrument", ISO6502 requirements and the data of T10, T30, T50, T60 and T90 required by Italian standards. ASTM-D5289, ISO-6502.

5. Application Industry:

It is the most important testing instrument stipulated by the state for the development of new products, the research of rubber formula, the control of rubber quality and the basic research and application of rubber. Widely used in all walks of life of rubber products.
