Silicon Powder A special trapping device is used to collect and process smoke and dust that escapes with waste gases during the smelting of industrial silicon and iron-silicon in an electric industrial furnace. Silicon fume is the name given to the smoke and dust that escapes from an industrial electric furnace. It contains 90% SiO2 and is made up of very small particles. 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, white colour, and reasonable distribution of particle sizes. 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 performance.
(2) Silicone powder can reduce exothermic peak temperatures of the curing reaction, and reduce linear expansion coefficients and shrinkage rates of the cured products, thereby eliminating internal stress in the cured products and preventing them from cracking.
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 in a reasonable range, which reduces and eliminates precipitation, delamination, and wear. It also increases the tensile, compressive, and thermal conductivity strength of the finished product. Improve flame retardant properties.
(5) Silicone treated with silane coupling is wettable to resins of different types, has good performance in adsorption, and can be easily mixed.
(6) Silicon powder The organic resin is filled with this filler, which improves performance while reducing the 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. Equipment is used for the Raymond mill, roller mill, disc (also called vertical mill), as well as punching and spinning. 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 mill has its own unique characteristics and its own advantages and drawbacks.
