Main Functions:

RT-101 Moving die rheometer is used with monolithic rotor control, which includes: host, temperature measurement, temperature control, data acquisition and processing, sensors, electrical chains, and other components. The temperature control circuit consists of a temperature control device, platinum resistance, and a heater capable of automatically tracking power and ambient temperature changes, and automatically correcting PID parameters to achieve fast and accurate temperature control. Data acquisition system and mechanical linkage to complete the rubber vulcanization process of force torch signal automatic detection, automatic real-time display of temperature and settings. After curing, automatic processing, automatic calculation, print the vulcanization curve, and process parameters. It shows curing time, curing power, and has a variety of audible alerts.

RT-101 Moving die rheometer controlled by computer, the computer setting the parameters of the direct control of test parameters rheometer. Display real-vulcanization curve and temperature curve, store test results, and different adjustable comparisons of test results in different colors.

Features:

1. This instrument is really confined mold cavity, and the United States Alpha (formerly Monsanto) has done. Repeatability and test data comparable with the Alpha. At the international leading position in the same industry.
2,.The instrument development platform is based on large databases, temperature control devices using the software to directly control, collect, and process. An instrument to overcome the general curing temperature of the shortcomings of using a temperature controller (poor accuracy). The technical leadership of international new trend.
3. This instrument has statistics, analysis, storage and comparison functions. Humanized design, easy to operate
4. Using imported high-precision sensors.

Technical parameter:

How it works:

The rubber sample into the mold cavity is almost entirely enclosed and maintained at test temperature, the mold cavity are of two parts, of which the lower part with a small linear reciprocating movement (swing oscillation), oscillatory shear specimen produced strain determination is the reaction torque of the mold cavity (force), this torque (force) depends on the shear modulus of rubber.
Curing test specimens after the start of the shear modulus increases, the computer machine real-time display and record the torque (force), when the torque (force) rose to a stable value or the maximum as well as return to the state, they get a torque ( force) and time curve, that is, curing curve (Figure 1), shape of the curve and test the temperature and plastic material characteristics.

Applicable industry：

Widely used in the rubber products industry.

RT-101 Rotorless Rheometer is used for dynamic testing of vulcanized rubber or rubber-like material. Curing curves and characteristic parameters can be obtained from MDR SOFTWARE based on the Fast Fourier Transform algorithm, such as ML, MH, ts1, ts2,  T10,  T50,  T90, S’, S”, S*, Tanδ, etc., which cover the sample’s stiffness and damping properties.
