JZ-6029 Type转子lessSulfur AnalyzerUsed for analyzing and measuring performance indicators such as scorch time, normal cure time, curing rate, viscoelastic modulus, and curing flat period during the rubber curing process, this testing instrument is stipulated by the national regulations for developing new products, researching rubber compound formulations, and inspecting product quality.
Manufacturers of rubber products can use a curing meter to test the reproducibility and stability of their products, as well as design and inspect rubber formulations. Producers can conduct on-site testing on the production line to ensure that the curing characteristics of each batch, and even at every moment, meet the requirements of the products. It measures the curing characteristics of uncured rubber compounds by oscillating the rubber within a mold cavity, obtaining a torque versus time curing curve, and scientifically determining the three key elements of curing time, temperature, and pressure, which 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 blending consistency, workability, to the physical properties of the finished product (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 production. In addition, the sulfur meter is also used for quality control, supervision during production, and the identification of product quality.
No rotorVulcanometer, FDR (Flat Die Rubber Vulcanometer), measures the torque change of rubber vulcanization under specified temperatures by placing the rubber between upper and lower flat plate molds and applying a sinusoidal torque vibration. The test instrument determines vulcanization characteristics by analyzing changes in torque, minor torque, scorch time, vulcanization time, and other factors like viscoelasticity. The precision and reproducibility of experimental results are achieved due to the cone rotary drive mechanism capable of generating the correct sinusoidal vibration and four heaters.
Due to the overall design of various components, a rubber vulcanizing tester with a compact structure suitable for various testing sites is used.

The principle of the rubber curing tester in determining the curing characteristics of uncured rubber: A sample of uncured rubber is placed into a sealed or nearly sealed mold cavity and maintained at a set test temperature. The mold cavity has upper and lower sections, with one section oscillating slightly. This oscillation induces shear strain in the sample, measuring the reactive torque (force) of the sample against the mold cavity. This torque (force) depends on the shear modulus, which continuously changes with curing time during the curing process of the rubber. Starting from when the rubber enters the mold, the curing tester automatically records the torque values reflecting the shear strain of the rubber. Consequently, a torque-time relationship curve, known as the curing curve, is obtained. Its shape is related to the set test temperature and the characteristics of the rubber.
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 method for obtaining rubber 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, causing the torque of the rotor's oscillation to increase proportionally. The variation in torque values is converted into signals by the sensors within the instrument and sent to the recorder for amplification and recording. The curve showing the torque's change over time is the curing characteristic curve.
The mouse buttons clicked on the rubber vulcanization instrument computer have the same function as the buttons on the main unit panel, facilitating user operation. The computer's software interface is extremely user-friendly and easy to use. Users can measure the scorch time, curing time, curing index, and low torque, making it an ideal device for the rubber industry to control rubber material quality, rapid testing, and fundamental rubber research.
