Inorganic nano-powder due to the fine particle size of inorganic nano-powder, large specific surface area, high surface energy, increased number of surface atoms, lack of atomic coordination and high surface energy, making these surface atoms have high activity, extremely unstable, it is easy to agglomerate together to form a number of connected boundaries The size of the surface is larger. This agglomeration of nanoparticles may It takes place during the synthesis stage, the drying process and the subsequent processing. The formation of these agglomerates makes the nanoparticles can not be uniformly dispersed with their single nanoparticles, and can not exert their due nanoparticle effect, which has a negative impact on the application performance of the nanopowder, so that in many cases there is no obvious difference between the application performance of the better dispersed microparticles. Therefore, the dispersion performance of inorganic nano-powder is very important.

In addition, both in inorganic matrix composites(such as multi-phase ceramics), metal matrix composites, polymer matrix composites, or inorganic nano-powder materials used in coatings, dyes, etc., there are also compatibility problems with the base material (including other inorganic components, metal base materials, polymer base materials, etc.). Good compatibility is one of the important conditions for obtaining high-performance nanocomposites.

Therefore, it is necessary to improve or enhance the compatibility between nano powder and other substances by surface modification or surface modification.Usually through the honeycomb mill modified machine to solve these problems, honeycomb millSpecifically for ultrafine powder particlesSurface modification or surface treatment coating,LordIt is composed of deagglomeration wheel, discharge door, air inlet, classifier, main engine, feed inlet, multi-channel surface dispersant inlet and feeder. The main engine consists of an air volume chamber, a mixing chamber and a number of crushing chambers. The structure and working principle of the machine can completely meet the technical requirements of good dispersion of powder and surface modifier, and equal opportunity of contact or action between powder and surface modifier.
