In the field of materials science, aluminum nitride demonstrates great potential in electronic industrial applications such as semiconductor substrates and structural packaging materials due to its excellent overall performance, especially its outstanding thermal conductivity. However, the extremely hydrophilic nature of aluminum nitride powder makes it very reactive with hydroxyl groups in water at room temperature, forming aluminum hydroxide and releasing ammonia, with a large amount of oxygen integrating into the aluminum nitride lattice, leading to a reduction in its thermal conductivity. Therefore, enhancing the water resistance of aluminum nitride powder has become key to expanding its application range.

In the aluminum nitride modification processing, the workflow of the honeycomb mill is efficient and precise. First, the material is rapidly dispersed by the shear force, frictional force, and centrifugal force generated by powerful air flow.Dispersed.Crushed and depolymerized back to the original particle size or natural crystalline form.Then.In the air, it intertwines and combines with the atomized modifier.,Forming a layer of nano-coating.After completing the coating modification, the finished product leaves the mill through the air flow and is transported to a reverse blow bag filter for collection. Throughout the process, the honeycomb mill also has a drying function. When the process gas is heated by a hot air generator, the honeycomb mill can turn into an efficient dryer. By controlling the outlet temperature, the drying degree of the product can be controlled. The drying process mainly breaks the hydrogen bonds on the surface of the nanoparticles, adsorbs moisture bridges and other chemical bonds, preventing the particles from sticking together, laying the foundation for subsequent surface treatment and spheronization. Deep drying can reduce the moisture content of the powder to. 0.05%.The aluminum nitride powder modified by the honeycomb mill.Has good chemical stability, and the pH value of the solution. Basically remains unchanged.

Under normal conditions, the honeycomb mill can apply more than two types of coating media, with a coating rate of up to. 99.2%, and an activation rate of 99.8%. The honeycomb mill can operate continuously, with a minimum processing capacity of 0.05 tons/hour and a maximum of 15 tons/hour, with a maximum moisture evaporation of 3 tons.And.Depending on the diversity of materials, different materials can be used inside the honeycomb mill equipment, retaining the advantages of color and purity of the materials. In the process of modifying aluminum nitride, it will not damage other excellent properties of aluminum nitride itself, maximizing the retention of the original performance advantages of aluminum nitride, allowing it to still meet the needs of various high-end applications after modification.
