Powder materials, as basic raw materials, are widely used in various fields such as chemical engineering, medicine, electronics, and building materials. From coatings and pigments to new energy battery materials, and from cosmetic fillers to nanoscale catalysts, the quality of powder materials directly determines the quality and performance of the end products. 。

The basic properties of powder materials are determined by their chemical composition and crystal structure, but surface characteristics also affect the material's dispersibility, fluidity, stability, and compatibility with other media. General Powders often have problems such as severe agglomeration, poor wettability, and low surface activity, making them difficult to meet the needs of high-end applications. Coating modification technology, by uniformly coating a functional material (such as polymers, metal oxides, coupling agents, etc.) on the surface of powder particles, can specifically improve the hydrophilicity, hydrophobicity, conductivity, and corrosion resistance of the powder. For example, coating organic polymers on the surface of nanoparticles can effectively inhibit particle agglomeration and improve their dispersion stability in solvents; while coating an anti-oxidation layer on the surface of metal powders can significantly extend the material's storage period.

The coating modification machine adopts a process mode that combines dynamic mixing and static reaction. Through high-speed stirring, airflow dispersion, and atomized spraying, the modifying agent is uniformly coated on the surface of the powder with a thickness of micrometers or even nanometers. The intelligent control system equipped with the equipment can monitor parameters such as temperature, speed, and material flow rate in real time to ensure the stability and repeatability of the coating process. In addition, the modular design allows the equipment to flexibly adjust parameters according to different powder characteristics and process requirements. Whether it is surface modification of high-hardness ceramic powders or coating of heat-sensitive pharmaceutical raw materials, efficient and safe production can be achieved.

In the production of lithium battery anode materials, graphite powder modified by coating can significantly improve the battery's charge-discharge efficiency and cycle life; in the coatings industry, surface-modified pigment particles can enhance the hiding power and weather resistance of the paint film; and in the plastic filling field, modified inorganic powders can effectively improve the mechanical properties of composite materials and reduce resin usage, reducing production costs.
