Thanks to its flexible process adaptability, the coating and modification machine is widely used in various fields such as mining, building materials, energy, and chemical industries. It offers customized processing solutions tailored to the functional requirements of different materials, making it a versatile upgrade tool for the multifunctional materials industry. 。

In the field of new-energy battery materials, this equipment can achieve spherical coating of graphite anodes and stability modification of high-nickel cathodes. For natural graphite, high-speed shear and collision forces induce plastic deformation of flaky graphite, forming a spherical structure. At the same time, an amorphous carbon layer is coated onto the surface, effectively preventing intercalation-induced delamination of the layered structure caused by electrolyte penetration, improving ion diffusion performance, and enhancing both the battery’s rate capability and cycle life.

In the field of thermal interface materials, our equipment effectively addresses the challenge of thermal-conductivity powder settling. For high-density powders such as alumina and boron nitride, we employ a polymer coating to create a density-buffering layer, thereby optimizing the apparent density of the powders to match that of the organic matrix. At the same time, leveraging the steric hindrance effect and chemical bonding provided by the coating, we firmly lock the powders within the three-dimensional polymer network, preventing oil-powder separation during storage and ensuring the integrity of the thermal conduction path, thus maintaining long-term stability in thermal conductivity. The modified thermal-conductivity powders can be widely used in products such as thermal silicone grease and potting compounds, significantly enhancing the thermal management reliability of end-use devices.

In the field of non-metallic mineral fillers, the equipment can perform surface modification on materials such as calcium carbonate, kaolin, and talc powder, thereby enhancing their compatibility with organic matrices like plastics, rubber, and coatings. The modified fillers not only significantly increase the filler loading capacity and reduce production costs but also improve the mechanical strength, wear resistance, and corrosion resistance of composite materials. Moreover, they can impart special functionalities to the materials—for instance, modifying talc powder and using it in plastic films can enhance the films' barrier properties and processing flowability. In addition, for conductive metal powders that are prone to oxidation and agglomeration, the equipment forms a dense coating layer to create a protective barrier, reducing surface energy and improving dispersibility and stability, thus ensuring long-term and reliable electrical conductivity.
