The coating and modification machine is adaptable to a wide range of recycled materials, effectively addressing the performance shortcomings of inorganic solid wastes and overcoming compatibility challenges in polymer materials, thus enabling each type of recycled material to find high-value applications. In the field of inorganic recycling materials, steel slag generated during steelmaking, after being crushed and sorted, can be used as a substitute for natural mineral fillers following coating and modification treatment, with broad applications in rust-proof paints, construction materials, and other sectors. Positive electrode materials recovered from power batteries—containing metals such as lithium, cobalt, and nickel—can be reused in power battery manufacturing after undergoing coating and modification, thereby achieving the recycling of rare metals. In the realm of polymer recycling materials, waste polyester, nylon, spandex, and other discarded synthetic fibers, after undergoing coating and modification, can be efficiently blended with matrix materials like HDPE, making them suitable for producing automotive parts and packaging materials. Furthermore, regenerated graphite, after being coated and modified, can meet the performance requirements for lithium-ion battery anode materials, helping to reduce costs and improve efficiency in the energy storage industry.

The technological core of the coating and modification machine lies in molecular-level interfacial control, which enables the construction of a uniform and dense functional coating layer on the surface of recycled material particles. Different materials are matched with dedicated process formulations to ensure that the modification effects are stable and controllable—rather than relying on simple mechanical mixing.

For the cathode materials used in power battery recycling, the mainstream approaches involve coating with carbon materials, oxides, or polymers. Taking carbon-material coating as an example, advanced techniques such as chemical vapor deposition are employed to uniformly coat materials like carbon nanotubes and graphene onto the surface of cathode particles. During this process, the thickness and density of the coating layer are precisely controlled, which not only reduces interfacial impedance and enhances the electron-transfer efficiency between the electrolyte and the cathode material but also inhibits side reactions such as dendrite growth and oxidation, thereby preventing performance degradation during battery cycling. As for recycled graphite anode materials, a liquid-phase coating process using coal-based pitch is adopted. After air oxidation and polymer cross-linking, a high-coking-value coated pitch is prepared, forming an amorphous carbon layer on the graphite surface. The “core-shell” structure effectively prevents the expansion and pulverization of graphite layers caused by co-intercalation of the electrolyte, significantly optimizing electrochemical performance.

The coating modification machine features precise and controllable performance, enabling adjustment of coating thickness down to the nanometer level. It allows for customized coating solutions tailored to address performance defects in various recycled materials—for example, carbon material coatings focus on enhancing conductivity, oxide coatings emphasize improving thermal stability, and polymer coatings prioritize optimizing flexibility, ensuring that the modified materials precisely meet end-use requirements. Encapsulating modification machine has High efficiency and continuity—featuring a modular design that supports continuous production, this system can handle various types of recycled materials ranging from micron-sized powders to granular particles, thereby preventing secondary contamination and material loss. The coating modification machine can also achieve... Multifunctional compounding enables the simultaneous implementation of multiple functions, such as grafting coupling agents, hydrophobization, and imparting conductivity—all without the need for additional processing equipment. This simplifies the modification process for recycled materials and reduces overall production costs.
