In the rubber industry production process, the quality of the mixed rubber has a significant impact on the subsequent processing and the final product quality. Therefore, research on the mixing process is highly valued and many achievements have been made.

At present, the rubber mixing process of our country's internal mixer has reached a considerable level of technology. Not only can the quality of the mixed rubber be fully qualified, but the quality uniformity of the mixed rubber is also very high. For example, 90% of the fluctuation of the Mooney viscosity between batches in general mixing can be within ± 4 or ± 3 Mooney values, and the remaining 10% is also within ± 5 or ± 4 Mooney values. The dispersion degree of the two-stage mixed rubber is mostly above level 6, and the energy consumption is reduced by about 5% to 10% compared to now, and the required time is reduced by 7% to 20% compared to now. In some factories, the mixing efficiency has been improved by 22.7%.

The basic performance and applicability of the neodymium aluminate system BR have made significant technological progress in just three years, fully demonstrating the enormous potential of China's synthetic rubber and tire industries. With the rapid development of scientific and technological progress, we should learn from this experience and further research and development of nano money based BR and multifunctional money based BR are needed to improve the quality and technological content of China's tire products. Only in this way can we stand undefeated in competition.
