Selection of highly dispersed fillers and compounding agents
The selection of fillers and compounding agents with high dispersibility is the basis for optimizing the dispersion of rubber mixing. Some fillers and compounding agents with high dispersibility include silica, calcium silicate, highly active zinc oxide and so on. These fillers and compounding agents can significantly improve the dispersibility and physical properties of rubber.

Optimize the formulation design to reduce the interaction between compounding agent and filler
Formulation design is one of the key factors affecting rubber dispersibility. Through reasonable formulation design, the interaction between compounding agent and filler can be avoided or reduced, and the condensation risk can be reduced. For example, auxiliaries and lubricants can be used to improve the dispersion of fillers and compounding agents to achieve a better mixing effect.
-
Increase the mixing temperature and improve the dispersion of fillers and mixtures
Temperature is another important factor affecting the dispersion of rubber. Increasing the mixing temperature can increase the dispersion of fillers and mixtures and reduce the risk of condensation. At the same time, properly increasing the temperature can also help to improve the mixing efficiency.
-
Mixing equipment with high mixing speed and high shear force
The mixing equipment with high mixing speed and high shear force can effectively disperse fillers and mixtures and improve the dispersibility and physical properties of rubber. For example, the use of high shear equipment such as internal mixers and extruders can promote the dispersion of fillers and mixtures.
-
Use dispersants and lubricants to improve the dispersibility of fillers and mixtures
The use of dispersants and lubricants is also an effective means to optimize the dispersion of rubber mixing. Dispersant can reduce the surface tension between filler and compounding agent and improve its dispersibility, while lubricant can improve the wettability of filler and compounding agent in rubber matrix and further improve the dispersion effect.
-
Control mixing time and pressure to ensure that compounding agents and fillers are fully dispersed
Controlling mixing time and pressure is also an important measure to optimize the dispersion of rubber mixing. By reasonably controlling the mixing time, the full dispersion of fillers and compounding agents can be ensured; at the same time, appropriate pressure can also promote the dispersion of fillers and compounding agents and reduce the risk of condensation.
-
Ensure sanitary and environmental conditions in the production process
The sanitary and environmental conditions in the production process are also one of the important factors affecting the dispersion of rubber. Ensuring the sanitary and environmental conditions in the production process can effectively reduce the problems of agglomeration and uneven distribution, and further improve the dispersion and quality of rubber. For example, regular cleaning of equipment and strict control of humidity in the production environment all help to optimize the dispersion of rubber mixing.
To sum up, the dispersion of rubber mixing can be optimized by selecting highly dispersed fillers and compounding agents, optimizing formulation design, increasing mixing temperature, adopting mixing equipment with high mixing speed and high shear force, using dispersants and lubricants, controlling mixing time and pressure, and ensuring sanitary and environmental conditions in the production process. Improve the quality and performance of the final rubber products. In the actual production process, it can be selected and applied according to specific needs and conditions.
