Function and Application of Rubber Vulcanization Tester (Vulcanization Meter Factory / Vulcanization Meter Manufacturer)

February 16, 2023

The rubber vulcanization tester (also called vulcanization instrument) is used to analyze and measure the scorch time, positive vulcanization time, vulcanization rate, viscoelastic modulus and vulcanization flat period of the rubber vulcanization process. , Research equipment for rubber compound formula and product quality inspection. Manufacturers of rubber products can use the vulcanizer to test the reproducibility and stability of the products, and to design and test the rubber formula. Manufacturers can conduct on-site testing on the production line to know whether the vulcanization characteristics of rubber in each batch or even every moment meet the product requirements. It is used to determine the vulcanization characteristics of unvulcanized rubber. The rubber reciprocates in the mold cavity to obtain a vulcanization curve of torque and time against the reaction torque (force) of the mold cavity. Scientifically determine the vulcanization time, temperature and pressure These three major factors, which are the key to ultimately determine the quality of the product, can also determine the physical properties of the compounding of the rubber compound. Quality management of raw materials, processing, and finished products:


1. Through the vulcanization curve, you can grasp the relevant characteristics of rubber in the vulcanization process. From the degree of rubber mixing, the processability to the physical properties of the product (such as anti-aging), etc. can be judged from the vulcanization curve. Further achieve the quality control of rubber.

Second, the vulcanization curve measured by the vulcanization instrument is widely used in the research of raw materials and formulas to provide data for processing and production. In addition, the vulcanization instrument is also widely used in production quality control, supervision and product quality identification.

1. Research and develop new formulas and new products: through the vulcanization instrument, you can obtain the curves generated by the rubber under different formulas, and then compare the cost, product quality ... and other items. It can effectively shorten the development time; it can evaluate the basic performance of a new formula or a new raw material.

2. Applied to the classification and identification of products: for example, natural rubber can be classified according to the results of the standard formula determined by the vulcanization instrument. The United Carbon Black Company of the United States regards the vulcanization curve as the best method to judge the quality of its carbon black, and only provides the vulcanization curve as a performance index for some products.

3. Using the vulcanization instrument to measure the positive vulcanization time is faster, more convenient and more accurate than the traditional method (that is, a group of test pieces vulcanized under different vulcanization conditions for drawing after stress and strain test), and the materials used are also Saving is indeed a quick and easy way to save. Vortex flowmeter

4. The application of scorch time can avoid the situation of dead glue, and can also judge the operability of the formula.

5. The vulcanization of thick-walled products such as tires is not an isothermal process, and the temperature of each part is very different. Using a vulcanization simulator and a vulcanization instrument controlled by a temperature process, it is possible to very realistically determine the rubber under actual heating conditions. The vulcanization process provides a strong basis for determining production and processing.

6. In terms of cost: shortened R & D time can greatly improve the efficiency of R & D funds, relatively speaking, it reduces the cost of R & D; the quality management of raw materials, processing and finished products can improve the efficiency of the use of raw materials , Reduce the waste of rubber.

Due to the accuracy and convenience of the vulcanization instrument, it has become one of the most effective means of offline (intermediate production) quality control in the production process of modern rubber plants. The relative error of the stress-strain test is usually 3% to 4%, and the vulcanization instrument is 1% to 2% or lower. Therefore, the slight differences in the raw materials or compounded rubber of each batch in the production can be easily found and play a role in quality control.

It can be seen that the accurate results of the test by the precision vulcanization instrument give an important technical basis during production, breaking the situation of ensuring quality by experience alone, thus avoiding the quality problems caused by the lack of sulfur or excessive sulfur and uneven mixing of the product. , Causing rework, saving costs, and improving production efficiency. It is fully capable to formulate formulas scientifically according to the requirements of the working conditions provided by users, and use advanced testing equipment to determine the technological parameters of vulcanization to ensure the performance of products and meet the quality requirements of users.
