Silicon Powder A special trapping device is used to collect and process smoke and dust escaping from an industrial electric furnace during the smelting of industrial silicon and iron-silicon. Silicon fume is the name given to the smoke and dust that escapes from an industrial electric furnace. It contains 90% SiO2, the particles are very small and average size is near nanometers. Performance and usage of silicon powder
The fine processing of silicon powder involves crushing, purifying and grinding quartz (also known as silica dioxide). It is characterized by its high purity, its white color, and a good particle size distribution. It has unique characteristics and is widely used.
Silicon Powder Performance
(1) Good insulation is achieved by silicon powder: Due to the high purity and low impurity levels of the powder, its stable performance and good electrical insulation, the cured products have good insulation and arc resistance.
(2) Silicone powder can reduce exothermic peak temperatures of epoxy resin curing reactions, and reduce linear expansion coefficients and shrinkage rates of the cured products, eliminating internal stresses and preventing cracked surfaces.
Silicon powder does not react easily with other substances. Silicon powder also doesn’t chemically react to most acids or alkalis. The particles are uniformly distributed on the surface and exhibit strong corrosion resistance.
The silicon powder particle size is a reasonable one. This allows for a reduction in precipitation, delamination, and wear resistance. Improve flame retardant properties.
(5) Silicon powder with silane coupling agent is easy to blend, has excellent wettability, and good adsorption.
(6) Silicone powder The organic resin is filled with this filler, which improves performance while reducing the product’s cost.
Preparation silicon powder
The preparation of silicon using blocks of silicon as the raw material can be done in many ways. There are four methods that produce better results and have a wider application: the Raymond method (also called the roller mill), the disc grinding method and the punching-and-spinning method. The Raymond method is used, as well as the roller mill, disc (also known vertical mill), and the punching and spinning methods. According to the milling principle, the first 3 are extrusion crushers, while the last are impact crushers. The structure of each mill is very different. Each has its advantages and disadvantages.
