Sulfurization Temperature MeasurementInstrumentUsed for analyzing and measuring performance indicators such as scorch time, normal curing time, curing rate, viscoelastic modulus, and curing plateau 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 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 each moment, meet the product requirements. The curing characteristics of uncured rubber compounds can be determined by oscillating the rubber within a mold cavity, obtaining a torque vs. time curing curve, 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 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 analyzer is widely used in the study of raw materials and formulations, providing data for processing and production. In addition, the sulfur analyzer is also used for quality control, supervision during production, and the identification of product quality.
Sulfur Temperature GaugeThe 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, burn 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 used.

The principle of the rubber curing tester for determining the curing characteristics of uncured rubber compounds: A sample of uncured rubber is placed into a sealed or nearly sealed mold cavity and maintained at a predetermined test temperature. The mold cavity consists of 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, generated during the curing process of the rubber compound. Starting from the moment the rubber compound is placed into the mold, the curing tester automatically records the torque values that reflect the shear strain of the rubber compound. Consequently, a torque-time relationship curve, known as the curing curve, is obtained. Its shape is related to the set test temperature and the properties 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 comprehensive 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 methods for obtaining胶料常数 such as shear values and time values from the curve.
Sulfurized ThermometerOperating Principle
The studio (mold) contains a rotor that continuously oscillates at a certain frequency (1.7 to 1.0 Hz) with a slight angle (3). The rubber material surrounding the rotor gradually increases in vulcanization degree and modulus under specific temperatures and pressures, causing the torque of the rotor's oscillation to increase proportionally. The change in torque values is converted into signals by the sensor inside the instrument and sent to the recorder for amplification and recording. The curve of torque changing with time is the vulcanization characteristic curve.
The mouse button clicked on the rubber vulcanization instrument computer performs the same function as the buttons on the main unit panel, facilitating user operation. The computer's software interface is highly user-friendly and extremely convenient to use. Users can measure burn time, scorch time, vulcanization index, and low torque, making it an ideal device for the rubber industry to control rubber material quality, conduct rapid inspections, and support fundamental rubber research.
