Low-temperature one-step rubber refining system

1. One-step mixing of the compound improves the efficiency of mechanical shearing, resulting in more uniform dispersion of carbon black and various compounding agents. This effectively avoids carbon black gelation during mixing, reduces irreversible chemical scission of rubber molecular chains, increases the number of reversible mechanically sheared molecular chains, improves the tensile strength, abrasion resistance, and fatigue resistance of the compound, reduces Mooney viscosity, and improves other physical properties, thus enhancing the quality of both the compound and the product. 2. A kneader vulcanization system is used, with kneaders arranged in series and parallel to improve the dispersion of sulfur. 3. Energy consumption is reduced compared to traditional processes that use energy-intensive internal mixers for multi-stage mixing; energy savings are approximately 25%. 4. The production capacity of the internal mixer is also maximized. The average number of mixing stages is 1.6, meaning a 1.6-fold increase in production capacity. 5. The automation level of the final mixing line is improved. 6. The quality of the compound is uniform and stable. 7. Labor and management costs are reduced.
