Reclaimed Rubber Curing Tester EquipmentUsed for analyzing and measuring the scorch time, optimum curing time, curing rate, viscoelastic modulus, and curing plateau period, etc., of the rubber curing process, this testing instrument is stipulated by the national regulations for the development of new products, research of rubber compound formulations, and quality inspection of rubber products.
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 inspections on the production line to ensure that the curing characteristics of each batch, and even at each moment, meet the requirements of the finished products. 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 are ultimately critical to product quality. It can also measure the physical properties of compounded rubber blends. Quality management of raw materials, processing, and finished products:
One - The vulcanization curve allows for the understanding of the relevant properties of rubber during the vulcanization process. From the mixing consistency of rubber, its 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 research 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.
Reclaimed Rubber Vulcanization Tester EquipmentThe FDR (Flat Die Rubber Deterioration Rheometer) is a testing instrument that measures the torque change of rubber during curing at a specified temperature, by mixing rubber between upper and lower flat plate molds and applying a sine wave torque vibration. The curing characteristics can be determined based on changes in torque, minor torque, burn time, curing time, and other factors such as viscoelasticity. Due to the cone rotary drive mechanism capable of achieving accurate sine wave vibration and four heaters, the instrument ensures precision and reproducibility of experimental results.
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 vulcanization tester in determining the vulcanization characteristics of unvulcanized rubber compounds: The unvulcanized rubber compound sample is placed into a sealed or nearly sealed mold cavity and maintained 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 reactive torque (force) of the sample against the mold cavity. This torque (force) depends on the shear modulus of the rubber compound during the vulcanization process, which varies continuously with the vulcanization time. Starting from the moment 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.
Rubber vulcanization meters 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 Meter) specifies the temperature control range, the range for recording the vulcanization curve (torque vs. time curve), and the method for obtaining rubber material constants such as shear values and time values from the curve.
Reclaimed Rubber Vulcanization Testing EquipmentOperating Principle
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 change in torque values is converted into signals by the sensors inside the instrument, which are then amplified and recorded on the recorder. The curve showing the torque variation over time is the curing characteristic curve.
The mouse button clicked on the rubber vulcanization instrument computer has the same function as the button on the main unit panel for user convenience. The computer's software interface is very user-friendly and extremely easy to use. Users can measure burn time, curing time, curing index, and small torque, making it an ideal device for the rubber industry to control rubber material quality, rapid testing, and basic rubber research.
