Heat dissipation material coating equipment, dispersing equipment, coating depolymerization machine


The working principle of the coating and modification machine integrates advanced mechanical design with physicochemical principles, aiming to achieve efficient and precise surface modification of powdered materials. Taking the commonly used honeycomb mill coating and modification machine as an example, it innovatively employs a wind-sweeping system. Once the powdered material enters the device, the wind-sweeping system immediately activates, generating a powerful airflow that thoroughly breaks up the powder particles that were originally agglomerated, ensuring that each particle is completely separated and exists independently. , laying the foundation for subsequent modification treatments.

While the powder is being dispersed, the addition of the modifier and the coating process are simultaneously taking place. The modifier is transformed into tiny droplets by a specially designed atomization device, and these droplets are evenly distributed throughout the internal space of the equipment. Thanks to the high-dispersion motion of the powder particles under the action of the air-sweeping system, they come into full contact with the atomized modifier droplets, enabling the modifier to coat each powder particle surface uniformly. This uniform coating is not merely a physical adhesion; rather, it involves molecular-level interactions that result in the formation of a dense, well-ordered, single-layer nanocoating film. Throughout the entire process, the airflow from the air-sweeping system not only helps disperse the powder and convey the material but also provides the driving force for the uniform distribution and coating of the modifying agent, thereby ensuring the efficiency and consistency of the modification treatment.

The process of first deagglomeration followed by drying is one of its key highlights. Traditional powder-processing techniques typically separate the deagglomeration and drying steps, which not only complicates the process flow but also may lead to secondary contamination or re-agglomeration of the powder during different processing stages. In contrast, the honeycomb mill advocates a process that first deagglomerates and then dries—cleverly integrating these two critical steps into a continuous workflow. Once the powdered material containing a certain amount of moisture enters the equipment, it is first subjected to the high-speed rotation of a deagglomeration rotor, where agglomerated powder particles are rapidly broken apart, restoring them to their original particle size or natural crystal morphology. At this point, the hot-air system inside the equipment begins to take effect. The hot air comes into full contact with the powder during the depolymerization process, rapidly removing free water from the powder’s surface and achieving the desired drying effect. This integrated process design not only enhances production efficiency but also ensures the purity of the powder and the uniformity of its particle size distribution.

The simultaneous implementation of surface modification is another unique feature of the honeycomb mill. While the particles are being disaggregated and dried, the surface modification process is also carried out in an orderly manner. As the powder particles are dispersed and brought into a dry state, the atomized modifying agent promptly comes into contact with them and undergoes a chemical reaction, forming a stable coating on the particle surfaces. This synchronized approach eliminates the time lag inherent in conventional processes that involve stepwise treatment, ensuring that the modifying agent can fully and uniformly bond with the powder, thereby enhancing the stability and consistency of the modification effect. For example, when producing high-thermal-conductivity ceramic powders used for heat dissipation in electronic devices, the honeycomb mill can simultaneously disaggregate and dry the ceramic powder while uniformly coating its surface with a modified additive that boasts high thermal conductivity. As a result, the final ceramic powder not only exhibits excellent dispersibility but also demonstrates outstanding thermal conductivity, thereby meeting the stringent performance requirements of thermal management materials for electronic devices.
