The rotorless vulcanization tester is the most widely used instrument in the rubber processing industry for controlling rubber quality, rapid testing, and basic research on rubber. It provides accurate data for optimizing rubber formulation combinations, and can accurately measure parameters such as scorch time, positive vulcanization time, vulcanization index, and maximum and minimum torque. Lixian specializes in producing rubber vulcanizers such as rotor less vulcanizers.

working principle:

 

Put the rubber sample into a nearly completely closed mold cavity and maintain it at the test temperature. The mold cavity has two parts, the upper part and the lower part, which move in a small linear reciprocating motion (oscillating oscillation). The oscillation causes the sample to generate shear strain. Measure the reaction torque (force) of the sample on the mold cavity, and the magnitude of this torque (force) depends on the shear modulus of the rubber.

 

After the start of the vulcanization test, 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 a stable or maximum value or even returns to the state, a curve of torque (force) versus time is obtained, namely, the vulcanization curve (as shown in Figure 1). The shape of the curve is related to the temperature of the test and the characteristics of the rubber compound.

 

Application industry:

 

It is the most important testing instrument specified by the state for the development of new products, the study of rubber formulations, the control of rubber quality, and the basic research and application of rubber. It is widely used in various industries of rubber products.

 

Criteria met:

 

The rotorless vulcanization tester meets the requirements of GB/T16584 "Rubber - Determination of vulcanization characteristics using a rotorless vulcanization tester", the requirements of ISO6502, and the T10, T30, T50, T60, and T90 data required by Italian standards.

Main features:

 

1. The rotorless vulcanizer adopts the latest version of the most advanced software in China, featuring fast temperature rise (within 3 minutes) and high temperature control accuracy.

 

2. The rotorless vulcanizer adopts an alpha sealed mold cavity structure, which is internationally leading.

 

3. The rotorless vulcanizer adopts advanced alpha force sensor technology: (sensor accuracy reaches 0.001 N.m)

 

4. The rotorless vulcanizer adopts the advanced alpha closed mold cavity structure, and the rotating cavity and the fixed cavity are sealed through the imported seal ring. Moreover, the closed mold cavity is completely different from the general open mold cavity in structure, and its precision, requirements and progressiveness are incomparable. The repeatability of the closed mold cavity is completely consistent, leading the world.
