In the process of modern industrial development, surface modification technology for inorganic powders is becoming increasingly important. It is a targeted treatment based on the specific performance requirements of powders for various industries. It not only meets the development requirements of new materials, new processes, and new technologies, but also significantly improves the performance of existing products, enhances production capacity and efficiency, therefore receiving considerable attention in the powder processing industry.

Currently, the surface modification methods for inorganic powders mainly include the following six categories:

Physical Coating Method This method uses polymers or resins to treat the surface of the powder. It can generally be divided into two processes: cold process and hot process.

Chemical Coating Method This method utilizes the functional groups in organic molecules to adsorb or chemically react on the surface of inorganic powders, thereby achieving coating of the particle surface. This method usually has two operation methods: dry method and wet method. In addition, it also includes surface coating modification using free radical reactions, chelation reactions, sol adsorption, etc.

Precipitation Reaction Method By carrying out precipitation reactions of inorganic compounds on the surface of particles, a single or multiple layers of “coating” are formed on the particle surface. This method can effectively improve the surface properties of the powder, such as gloss, coloring power, covering power, color retention, weather resistance, and electrical, magnetic, and thermal properties, while also having a certain improvement effect on bulk properties.

Mechanochemical Method Using ultrafine pulverization and other high-intensity mechanical actions to specifically activate the powder surface. To a certain extent, it can change the crystal structure, dissolution performance (showing surface amorphization), chemical adsorption, and reaction activity (increasing surface active points or active groups) of the particle surface.

Intercalation Modification Method Given that the bonding force between the crystal layers of layered mineral powder particles is relatively weak (such as molecular bonds or van der Waals forces), or the presence of exchangeable cations, the interfacial properties and other related properties of the powder are changed through ion exchange reactions or chemical reactions.

High-Energy Surface Modification Method This refers to the method of using high-energy means such as ultraviolet rays, infrared rays, corona discharge, plasma irradiation, and electron beam irradiation to modify the surface of powders.

The ideal equipment for processing these modification methods is the honeycomb mill. It is a continuous powder surface modification machine specially designed for surface modification or surface treatment coating of ultrafine powder particles. The equipment mainly consists of depolymerization wheels, discharge ports, air inlets, classifiers, main bodies, feed ports, multiple surface dispersant inlets, and feeders. Its unique structure and scientific working principle can fully ensure that the powder and surface modifier achieve a good dispersion effect, and make the powder and surface modifier have equal contact or interaction opportunities, fully meeting the relevant technical requirements. In practical applications, with its excellent performance, it provides an efficient and reliable solution for the surface modification of inorganic powders, helping various industries achieve better results in the field of powder processing.
