The particle size of conventional magnesium hydroxide powder is usually at the micron level, and the particles are relatively coarse. And when we refine magnesium hydroxide down to the nanoscale with the help of advanced nano-grinding technology, everything becomes different. From the intuitive data, the particle size of micron-sized magnesium hydroxide may be a few microns or even a dozen microns, while the particle size of nano-scale magnesium hydroxide is precisely controlled between 1 and 100 nanometers.
The specific surface area of nanoscale magnesium hydroxide increases exponentially. An increase in the specific surface area means that the "interface" between the material and the outside world is greatly widened. When applied as a flame retardant, more active sites are able to interact quickly with the surrounding environment. When exposed to high temperatures, the atoms on the surface of nano-magnesium hydroxide can quickly capture the heat, start the decomposition reaction, release a large amount of water vapor, efficiently dilute the surrounding oxygen concentration, and inhibit the spread of flames. Moreover, due to the extremely small particle size, nano-magnesium hydroxide can be more evenly dispersed in the polymer matrix and accurately distributed in every corner, which greatly improves the flame retardant effect, and the flame retardant efficiency is significantly improved compared with micron-sized magnesium hydroxide.
In the nano grinding journey of magnesium hydroxide, cell mill is undoubtedly the core weapon. The cell mill combines two advanced technologies: gravity and fluid. When the stirring shaft rotates at high speed, the grinding balls filled in it are driven by vortex currents, and they move violently in the grinding chamber, colliding and squeezing each other. Under the impact, the magnesium hydroxide raw material is gradually crushed and refined. It lays a solid foundation for high-performance applications of magnesium hydroxide. Cell mills are mostly used in large-scale industrial milling equipment, and the output is higher than that of ordinary mills. Its efficient production capacity can meet the needs of different material processing, especially in the field of nano powder material processing, which is of great significance for large-scale production. In some large-scale material processing enterprises, cell mills can quickly process a large number of powder materials, improve production efficiency and reduce production costs.
