PreparationThe purpose of ultrafine aluminum hydroxide powder is to reduce the particle size of aluminum hydroxide to micron or even nanometer level to improve its physical and chemical properties. By grinding, aluminum hydroxide particles can be refined to increase its specific surface area, thereby improving its surface activity, reactivity and adsorption. This helps to improve the application of aluminum hydroxide in various fields such as flame retardant performance, filling performance, reinforcement performance, etc..
The grinding method of aluminum hydroxide mainly includes two categories: physical method and chemical method. Physical methods rely mainly on grinding equipment, such as vertical mills(cell mill), ultra-fine mill, jet mill, etc. These devices can break up aluminum hydroxide solid blocks or particles into finer particles by crushing, shearing, grinding, etc. Chemical methods involve chemical reactions or modification of the surface of aluminum hydroxide to change its surface properties,
In the physical grinding method, the vertical grinding machine（cell milling）It is a commonly used equipment.The cell mill is a kind of ultra-fine grinding equipment consisting of a stationary cylinder filled with grinding media and a rotating stirrer. It is composed of feeding system, grinding cylinder, grinding disc, transmission system and electric control system. The working mode of vertical arrangement, lower feeding and upper discharging enables the cell mill to fully use the mill body to support the power and transmission system, saving the pressure of the slurry sealing device and the feeding port, and the equipment occupies a smaller area.This equipment has the advantages of simple process, low cost, convenient operation and maintenance of output.
Typically, cell mills can grind materialParticle size range of 1 micron and below 100 nm.In many applications, the total cost of the user can be reduced to a minimum, to meet the production process at the same time, significantly improve the user's efficiency.
