The Purpose of Surface Treatment of Aluminum Hydroxide Powder

Powder surface modification refers to the modification of the surface of powder materials by physical, chemical, mechanical and other methods. The surface and physical and chemical properties of powder materials are purposefully changed according to the needs of the application, such as surface composition, structure and functional groups, and surface energy. , Surface wettability, electrical properties, light properties, adsorption and reaction characteristics, etc., to meet the needs of the development of modern new materials, new processes and new technologies.

1. Change the physico-chemical properties of the filler surface, improve its dispersibility in resins and organic polymers, improve the compatibility between the basic interface of fillers and resins, and then improve the mechanical properties of materials such as plastics and rubber. The main purpose of surface modification of minerals as fillers.

2. The main purpose of changing the mineral surface of paper-making fillers is to change the surface charge properties of the particles and increase the bonding strength with the oppositely charged fibers, thereby improving the paper strength and the retention rate of the filler during the paper making process.
