JZ-6029 computer model without a rotorSulphur AnalyzerUsed for analyzing and measuring the scorch time, normal curing time, curing rate, viscoelastic modulus, and curing flat period of the rubber vulcanization process, this testing instrument is stipulated by the national regulations for the development of new products, research on rubber compound formulations, and quality inspection of rubber products.
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 at every moment, meet the product requirements. The vulcanometer is used to determine the vulcanization characteristics of unvulcanized rubber compounds by oscillating the rubber within a mold cavity, obtaining a torque versus time vulcanization curve, which scientifically determines the three key elements of vulcanization time, temperature, and pressure – these ultimately determine product quality. It can also measure the physical properties of compounded rubber blends. Quality management of raw materials, processing, and finished products:
One - Through the vulcanization curve, one can grasp the relevant characteristics of rubber during the vulcanization 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 vulcanization curve. This further achieves control over rubber quality.
The sulfur curve measured by the sulfur meter is widely used in the research of raw materials and formulations, providing data for processing and production. In addition, the sulfur meter is also used for quality control, supervision during production, and the identification of product quality.
No RotorSulfur Analyzer, FDR (Flat Disk Rubber Sulfur Analyzer), is a test instrument that measures the torque change of rubber vulcanization by placing the mixed rubber between the upper and lower flat plate molds at a specified temperature and applying a sinusoidal torque vibration. The vulcanization characteristics can be determined based on changes in torque, minor torque, burn time, vulcanization time, viscoelasticity, and other factors. The precision and reproducibility of experimental results are achieved due to the cone rotary drive mechanism capable of correct sinusoidal vibration 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 rubber vulcanization tester in determining the vulcanization characteristics of unvulcanized rubber material: The unvulcanized rubber material sample is placed in a sealed or nearly sealed mold cavity and maintained at the set test temperature. The mold cavity consists of upper and lower parts, where one part oscillates at a tiny angle. This oscillation induces shear strain in the sample, and the reactive torque (force) of the sample against the mold cavity is measured. This torque (force) depends on the shear modulus, which continuously changes with the vulcanization time, generated during the vulcanization process of the rubber material. Starting from when the rubber material enters the mold, the vulcanization tester automatically records the values of the torque reflecting the shear strain of the rubber material. Consequently, a torque-time relationship curve, or vulcanization curve, is obtained, which is related to the set test temperature and the characteristics of the rubber material.
There are mainly two types of rubber vulcanization meters: reciprocating measurement and torsional measurement. The latter is more widely used due to its ability to test samples more comprehensively. The National Standard 80V/’$%’W&’’((Disk Oscillating Vulcanization Meter Method) specifies the temperature control range, the range for recording the vulcanization curve (torque vs. time curve), and the methods for obtaining rubber material constants such as shear values and time values from the curve.
The working principle of a rubber vulcanization tester
Inside the workshop (mold), there is 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, which proportionally increases the torque of the rotor's oscillation. The change in torque values is converted into signals by the sensors inside the instrument and sent to the recorder for amplification and recording. The curve showing the change of torque over time is the curing characteristic curve.
The mouse buttons clicked on the rubber vulcanization tester's computer have the same functions as the buttons on the main unit's panel, facilitating user operation. The computer's software interface is extremely user-friendly and easy to use. Users can measure scorch time, normal vulcanization time, vulcanization index, and small torque, making it an ideal device for the rubber industry to control rubber quality, conduct rapid testing, and conduct fundamental rubber research.
