Inorganic non-metallic material Silicon Micropowder


What is Silicon Micropowder?

Silicon micropowder is a non-toxic, odorless, and pollution-free material. "It has excellent dielectric properties, low coefficient of thermal expansion, and high thermal conductivity. The silicon micro powder series products are made from pure quartz powder through an advanced ultra-fine grinding process. They have the advantages of high whiteness, fine particles, reasonable particle size distribution, large specific surface area, excellent suspension performance, and high purity. They are widely used in coatings, paints, adhesives, silicone rubber, precision casting, high-end ceramics, epoxy resin potting materials, and ordinary electrical appliances." Insulating casting of high-voltage components, plastic and potting materials for integrated circuits, powder coatings, protective layers for welding electrodes, and other resin fillers. Silica powder is gray, with spherical particles and beautiful particles. The smallest particles are less than 0.01 UM, with an average particle size of 0.1-0.3 UM. It is easy to form loose lumps under moderate temperatures and has high gelling and adsorption capacity. It is widely used in hydropower engineering, refractory materials, highways, bridges, tunnels, chemical ceramics, rubber, and other industries.

Properties of Silicon Micropowder

Silicon micro powder is an inorganic non-metallic functional filler with excellent performance. Silicon micro powder is a micro powder produced by processing natural quartz (SiO2) or fused quartz (amorphous SiO2 after natural quartz is melted and cooled at high temperature) through multiple techniques such as crushing, ball milling (or air flow milling), flotation, acid washing purification, and high purity water treatment. Silicon dioxide powder material processed through multiple processes has excellent acid and alkali corrosion resistance, wear resistance, and low linear expansion coefficient. Due to its superb filling properties, silica fume is widely used in silicone rubber, potting adhesives, floor coatings, and industrial coatings. Adding silica fume can improve the surface hardness of materials, resist scrubbing, and reduce filling costs. With the development of the industry, in some industrial fields, fillers need to meet the following characteristics: high filling ratio, good storage stability, and low viscosity when used. However, using the previous methods of using silica powder raw materials have yet to meet the current requirements of these industrial products.


Application of Silicon Micropowder in Coatings

The main functions of silicon powder in coatings are 1—barrier effect. During the coating process, the paint film is spread out due to the development of surface tension before curing, automatically forming a specific silicon powder coating layer to play a protective role; Improve scrub resistance. The Mohr hardness of silicon powder is around 7. After the paint film is dried, it can effectively improve the hardness of the paint film. In addition, silicon powder is an oxide powder with partial hydroxyl distribution on the surface, which can form a better hydrogen bond with the substrate or system to improve scrub resistance; Insulation: Silicon powder itself has a high volume resistivity and no free ionic impurities, which can effectively improve the surface resistance of the paint film and improve insulation; Fire-resistance, the component of silicon powder is silicon dioxide. When added to the organosilicon resin or organosilicon boron resin, eutectic reactions will occur at high temperatures to form new ceramic phases, protecting the substrate; Silica powder for coating is a new type of functional green environmental filler. Due to its unique chemical inertness and mineral properties, it can effectively improve the paint film's weather, wear, and fire resistance. In addition, it is an inorganic filler, free of organic and ionic impurities, matching the future development trend of green environmental protection of coatings.
