Surface modification refers to the use of various types of materials or additives, the use of physical,Chemistry, etc.The surface of the powder is treated by the method, and the physical and chemical properties or physical and technical properties of the powder surface are purposefully improved according to the needs of the application, such as surface crystal structure and functional groups, surface energy, surface wettability, electrical properties, surface adsorption and reaction characteristics, etc., to meet the needs of the development of modern new materials, new processes and new technologies..

Purpose of surface modification：Make inorganic mineral filler from general extender filler into functional filler;Provide new technical methods for polymer materials and composite materials;Improve pigment dispersion in coatings or paints and improve coating performance;Make the product have good optical effect or visual effect, high added value;Improve the dispersion of particles and prevent particle agglomerationWait.

At present, there is no clear classification method for the surface modification of particulate materials. If the modification methods are classified according to the state of the modifier and the particles in the modification process, the surface modification of the particles can be divided into three categories: dry modification, wet modification and gas phase modification.

A typical powder modification coating process involves several key steps. First, the powder particles are pre-treated to ensure that they are suitable for modification. This pretreatment may include cleaning, drying, or particle sizing. Next, according to the desired performance and function, the modification is selected agent. Such a modifier may be a polymer, a surfactant, or other additives capable of improving the dispersibility, wettability, or adhesion of the powder particles. The modifying agent is then applied to the powder particles by spraying, mechanical mixing or chemical reaction.Industrial production in general use of machinery and equipment"Honeycomb mill" is modified. Honeycomb mill is an equipment specially designed for the modified production of functional materials. It can simultaneously realize grinding, drying, sorting, and surface chemical treatment with powder, and at the same time dry and depolymerize wet mill filter cake and slurry.After the modifier is applied, the powder particles are usually heated or cured to ensure the adhesion and stability of the coating. Finally, the powder particles after modification and package are tested and evaluated to verify their enhanced performance and performance.
