Carbon black, as a key industrial raw material with high specific surface area, excellent conductivity and reinforcement properties, has been deeply integrated into core fields such as rubber, coatings and inks, battery manufacturing, and plastics. In the rubber industry, it is the core reinforcing filler for automotive tires and other products, which can significantly improve the mechanical strength and wear resistance of the products; In the field of coatings and inks, it has become the core black pigment with excellent coverage and weather resistance; In lithium battery manufacturing, as a conductive agent, it can reduce battery internal resistance and improve charging and discharging efficiency. However, the surface energy of carbon black particles is extremely high, making it easy to form aggregates. The uniform mixing with the matrix material directly determines the final product performance. The SMIDA
planetary centrifugal mixer provides a professional solution for efficient mixing of carbon black with its core technology of "revolution+rotation dual power+vacuum defoaming".
Carbon black mixing has long faced common pain points in the industry: firstly, there is strong cohesive force between carbon black aggregates, and traditional mixing equipment is difficult to completely break the aggregates, resulting in uneven dispersion, such as black lumps in rubber products and discontinuous conductive networks in lithium batteries; Secondly, during the mixing process, it is easy to get involved in air, and if tiny bubbles remain, they can cause defects such as pinholes in the paint film and a decrease in the mechanical properties of rubber products; Thirdly, the viscosity of carbon black mixed systems (such as rubber carbon black, coating carbon black, battery slurry carbon black) varies greatly in different application scenarios, and traditional equipment has poor adaptability, making it difficult to ensure consistency among multiple batches of products. These problems seriously restrict the full utilization of carbon black function and affect the quality of end products.
SMIDA planetary centrifugal mixer solves the above problems from the technical root. The core dual power structure of "revolution+rotation" enables the stirring blade to rotate at high speed while revolving around the center of the stirring cylinder, forming a strong shear flow field and centrifugal force field, which can efficiently tear apart carbon black aggregates, promote the comprehensive and deep infiltration and fusion of carbon black particles with rubber, resin, solvents and other matrix materials, ensure uniform dispersion of carbon black, and fully exert its core functions such as reinforcement and conductivity. For the pain points of bubbles, the equipment is equipped with a high-precision vacuum pump system, which can maintain a stable vacuum environment throughout the mixing process. Under the dual action of centrifugal force and negative pressure, small bubbles in the mixing system are quickly captured and completely discharged, ensuring the quality of product molding from the source. In addition, the equipment can flexibly adjust parameters such as revolution/rotation speed and vacuum degree according to the viscosity characteristics of the carbon black mixing system, adapting to diverse needs from laboratory trials to industrial mass production.
Whether it is the preparation of tire rubber materials in the rubber industry, the formulation of color pastes in the coating and ink industry, or the mixing of conductive pastes in the lithium battery field, SMIDA planetary
centrifugal mixers can accurately match the needs. Through automation and high-precision mixing control, the equipment not only significantly improves the efficiency of carbon black mixing, but also ensures the consistency of product batches, helping enterprises optimize production processes, enhance the competitiveness of end products, and empower the application of carbon black in multiple high-end fields.
