Abstract
Mixing is the most important production process in rubber production and processing. Essentially, mixing is the technique of uniformly dispersing fillers and small materials in raw rubber, which directly determines the performance and durability of rubber products. This study focuses on overcoming the limitations of the batch mixing technique by combining the wet mixing and continuous mixing techniques, such that their advantages complement each other. In addition, this paper proposes a full formula wet mixing technique, wherein wet continuous mixing used full formula of carbon black to resolve the issue of carbon black flying, which occurs due to the small size of carbon black particles and causes pollution in the air and harmful effects in humans. Based on experimental datasets, it can be inferred that there is desirable mutual synergy between the full formula wet process and the continuous mixing technique, which can simplify the process of adding small materials during the mixing process and improve the quality of mixed rubber as well as promote continuous rubber production. Furthermore, the basic physical properties such as tensile and tear and dynamic mechanical properties of the produced rubber are significantly improved compared with those of the rubber produced by conventional mixing.
