OSCILLATING DISK RHEOMETER: HIWA 100

The HIWA 100 Rheometer is used for measuring the curing characteristics of rubber vs. time at constant temperature . In Hiwa 100 Rheometer , rubber paste is placed inside cavity under constant temperature and mechanical deformation is continously applied to it by an oscillating rotor . The oscillation of rotor can be adjusted mechanically at angles ±1°, ±3°, ±5° . Before test execution , cavity and rotor is heated up to predefined temperature . After placing of specimen , two die semi cavities are closed by a pnumatic cylinder. Rubber starts to cure and rotor starts to oscillate . The necessary torque for oscillating motion is increased gradually by curing of rubber paste . The magnitude of torque is measured by electronic system and simultaneously the torque - time curve is monitored by computer. After ending of test the two semicavities are opened by pnumatic cylinder and the cured specimen can be drawn out easily . The machine is fully controlled by a software via a computer attached to the machine . The software is so designed that training can be done in very short time and It is userfriendly.
