JZ-6029 Rubber Vulcanizing InstrumentUsed for analyzing and measuring performance indicators such as scorch time, normal curing time, curing rate, viscoelastic modulus, and curing flatness period during the rubber curing process, this testing instrument is specified by the national regulations for developing new products, researching rubber compound formulations, and inspecting product quality.
Manufacturers of rubber products can use a vulcanometer to test the reproducibility and stability of their products, as well as design and inspect rubber formulations. Producers can conduct on-site inspections on the production line to ensure that the vulcanization characteristics of each batch, and even each moment, meet the requirements of the products. To determine the vulcanization characteristics of unvulcanized rubber compounds, a torque-time vulcanization curve is obtained by reciprocating oscillation of the rubber within the mold cavity, which helps scientifically determine the three key factors of vulcanization time, temperature, and pressure – they are ultimately critical to product quality. It also allows for the determination of the physical properties of the compounded rubber. Quality management of raw materials, processing, and finished products:
One - Through the curing curve, one can grasp the relevant characteristics of rubber during the curing process. From the rubber's mixing consistency, workability, to the physical properties of the finished products (such as resistance to aging), all can be read from the curing curve. This further achieves control over rubber quality.

In addition, the sulfur tester is also used for quality control, supervision during production, and the identification of product quality.
Rubber Viscosity RecorderThe FDR (Flat Die Rubber Hardness Tester) measures the torque change of rubber during curing by placing the rubber between upper and lower flat plate molds and applying a sinusoidal torque vibration at a specified temperature. The curing characteristics can be determined by analyzing changes in torque, minor torque, scorch time, curing time, and other factors such as viscoelasticity. The precision and reproducibility of experimental results are achieved due to the cone rotary drive mechanism capable of producing accurate sinusoidal vibrations and the presence of four heaters.
Due to the overall design of various components, a rubber vulcanization tester with a compact structure suitable for various testing sites is adopted.

The principle of the rubber curing tester in determining the curing characteristics of uncured rubber compounds: The uncured rubber compound sample is placed into a sealed or nearly sealed mold cavity and kept at a set test temperature. The mold cavity consists of upper and lower parts, with one part oscillating at a slight angle. This oscillation induces shear strain in the sample, measuring the counter-torque (force) exerted by the sample on the mold cavity. This torque (force) depends on the shear modulus of the rubber compound during the curing process, which changes continuously with the curing time. Starting from when the rubber compound is placed into the mold, the curing tester automatically records the torque values reflecting the shear strain of the rubber compound. Consequently, a torque-time relationship curve, i.e., the curing curve, is obtained. Its shape is related to the set test temperature and the characteristics of the rubber compound.
Rubber vulcanization testers come in two main forms: reciprocating measurement and torsional measurement. The latter is more widely used due to its ability to provide a more complete sample. The National Standard 80V/'$%'/W/''' (Disk Oscillating Vulcanization Tester) specifies the temperature control range, the range for recording the vulcanization curve (torque vs. time curve), and the method for obtaining rubber constants such as shear values and time values from the curve.
Rubber curing testerOperating Principle
The studio (mold) contains a rotor that continuously oscillates at a certain frequency (1.7-0.1 Hz) with a small angle (3). The rubber material surrounding the rotor gradually increases in curing degree and modulus under specific temperatures and pressures, resulting in a proportional increase in the torque of the rotor's oscillation. The change in torque value is converted into a signal by the sensor inside the instrument and sent to the recorder for amplification and recording. The curve showing the torque variation over time is the curing characteristic curve.
The mouse button clicked on the rubber vulcanization tester computer has the same function as the button on the main unit panel, facilitating user operation. The computer's software interface is very user-friendly and extremely convenient to use. Users can measure the scorch time, curing time, curing index, and small torque, making it an ideal device for the rubber industry to control rubber quality, conduct rapid inspections, and perform fundamental rubber research.
