What is silica powder used for?

Overview of spherical silica powder

Spherical silica fume is a non-toxic, odorless, non-polluting inorganic non-metallic material. ), flotation, acid washing purification, high-purity water treatment and other processes. In short, ultra-fine grinding and purification are two important links in the preparation of silicon micropowder. Natural quartz minerals contain a large number of inclusions and cracks. The number of cracks and defects can be greatly reduced by using ultra-fine grinding technology. Combined with the purification process, the content of harmful impurities can be better reduced. As far as the current pulverization technology is concerned, the equipment available for natural quartz minerals includes ball mills, mixers, jet mills and vibration mills. Ball mill and vibration mill plus classifier system, the product particle size is small, and the system adjustment is more flexible.

Nano-silica SiO2 Nano-silica particles can improve the coating's adhesion, scrub resistance, weather resistance, strength, hardness, toughness and elasticity, aging resistance, UV resistance and other properties, and significantly improve the coating's self-cleaning properties , waterproof and water permeability, wear resistance, corrosion resistance, color retention and other properties, has a good effect in the modified coating. After surface treatment, it is hydrophilic and lipophilic.

Application of spherical silica powder

The spherical silica powder technology is based on natural high-quality powdered quartz minerals as the basic raw material. It is made by two main processes: 1. Using sol-gel technology, in the presence of dispersant and spherical catalyst, high-purity spherical nano-amorphous silicon powder that meets the requirements of electronic packaging materials is prepared; 2. Using flame method or It is melted into spherical amorphous silicon powder by ion flame method. In the high-end user market, such as integrated circuit packaging, the second process is used.
