Section IISilicone vulcanization testerAnalytical instruments used for measuring the scorch time, optimal curing time, curing rate, viscoelastic modulus, and curing flatness period in the rubber vulcanization process, as stipulated by the national regulations, are essential for developing new products, researching rubber compound formulations, and inspecting product quality.
Manufacturers of rubber products can use a curing analyzer to test the reproducibility and stability of the products, as well as design and inspect rubber formulations. Producers can conduct on-site inspections on the production line to ensure that the curing characteristics of each batch, and even each moment, of rubber 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-time curing curve based on the reactive torque (force) of the mold cavity. This scientifically determines the three key factors 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 and processability 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 research of raw materials and formulations, providing data for processing production. In addition, the sulfur analyzer is also used for quality control, supervision during production, and the identification of product quality.
Section 3: The FDR (Flat Die Rubber) vulcanometer is a testing instrument that determines the vulcanization characteristics of rubber by measuring the torque change during vulcanization, under specified temperatures, when rubber is placed between upper and lower flat plate molds and subjected to sinusoidal torque vibration. It calculates vulcanization properties based on changes in torque, minor torque, burn time, vulcanization time, and other factors like viscoelasticity. The instrument achieves precision and reproducibility of experimental results due to its conical rotary drive mechanism capable of producing accurate sinusoidal vibrations and four heaters. The vulcanometer features a compact structure designed for various testing environments, thanks to the overall design of its components.

The principle of the rubber vulcanization tester in determining the vulcanization characteristics of unvulcanized rubber compounds: A sample of unvulcanized rubber is placed in a sealed or nearly sealed mold cavity and maintained at a set test temperature. The mold cavity has two parts, upper and lower, with one part oscillating slightly. 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 of the rubber compound, which varies continuously with vulcanization time during the vulcanization process. Starting from when the rubber compound enters the mold, the vulcanization tester automatically records the torque values reflecting the shear strain of the rubber compound. Consequently, a torque-time relationship curve, or vulcanization curve, is obtained. Its shape is related to the set test temperature and the characteristics of the rubber compound.
Silicone Rubber VulcanometerThere are mainly two types: 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 Vulcanometer Method) specifies the temperature control range, the range for recording the vulcanization curve (torque vs. time curve), and the method for obtaining胶料常数 such as shear values and time values from the curve.
Five,Silicone Rubber Vulcanization TesterOperating Principle
Inside the studio (mold), a rotor continuously oscillates at a certain frequency (1.7-0.1 Hz) with a slight angle (3). The rubber material surrounding the rotor gradually increases in vulcanization degree and modulus under specific temperature and pressure, causing the oscillation torque of the rotor to increase proportionally. The changes in torque values are converted into signals by the sensors inside the instrument, sent to the recorder for amplification and recording. The curve showing the torque's change over time is the vulcanization characteristic curve.
The mouse button clicked on the rubber curing instrument computer has the same function as the button on the host panel, for easy user operation. The computer's software interface is quite user-friendly and very convenient to use. Users can measure the scorch time, cure time, curing index, and low torque, making it an ideal device for the rubber industry to control rubber material quality, rapid inspection, and fundamental rubber research.
