Vulcanization is an important process in the processing of rubber products. In this process, the rubber undergoes a series of complex chemical changes. The rubber changes from a plastic compound rubber to a highly elastic or hard cross-linked rubber, so as to obtain more perfect physical and chemical properties, to improve and broaden the use value and application range of rubber materials. Therefore, vulcanization is of great significance to the manufacture and application of rubber and its products.
The so-called vulcanization means that under heating conditions, the raw rubber in the rubber compound chemically reacts with the vulcanizing agent so that the rubber is cross-linked from linear structure macromolecules into three-dimensional network structure macromolecules. This process is called vulcanization. The process of this cross-linking reaction is completed under certain temperature, time and pressure conditions. These conditions are called vulcanization conditions. In the rubber industry, these vulcanization conditions are indispensable when people make compound formulas, understand the rubber performance and check rubber quality. How to reproduce these conditions in a laboratory? People have to develop an apparatus which can establish these vulcanization conditions of rubber to formulate and verify the required vulcanization formula and get some necessary parameters for regular production. The rubber rheometer can satisfy these needs, and It plays a vital role in the vulcanization process.
