Wet continuous mixing technique based on full formula of carbon black

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.

Wet continuous mixing technology and extrusion rheological properties of carbon black/natural rubber composites

“…Since some volatile organic gasses can be produced with the reactions between compounding ingredients, an exhaust section is set up to discharge the gases. These components not only ensure the continuity of the mixing but also further improve the degree of dispersion and distribution of the filler, achieving a high‐quality continuous mixing process, providing technical guidance for the preparation of high‐performance rubber composites 31 …”

Continuous conveying and mixing characteristics of high‐viscosity materials under acoustic vibration excitation

“…Continuous mixing process can achieve the homogeneity of the components while conveying the material, thereby enhancing mixing efficiency and reducing the time consumed by stopping, loading, and unloading 2 . This approach has found wide applications in the chemical, food, and pharmaceutical industries, 3 where efficient and precise mixing is essential for product quality. The viscosity characteristics of fluids are a major determinant of the mixing and conveying efficiency of continuous mixing systems, making it a critical factor in their performance 4 .…”
