Silicon Fume (Microsilica or Silica Fume), also called Microsilica Fume, is technically known as "Silica Fume". It is collected and treated by special collecting devices during the high-temperature smelting of industrial silicon and iron silicon by industrial electric furnaces. Microsilica or Silica Fume is a special collection device that collects and deals with the Fume emitted by industrial electric furnaces during the high-temperature smelting of industrial silicon and ferrosilicon. In the escaped soot, SiO2 content accounts for about 90% of the total soot, the particle size is very small, the average particle size is almost nano level, so it is called silica powder.
Properties of silicon powder
(1) Good insulation: due to the high purity of silicon powder, low impurity content, stable performance, excellent electrical insulation performance, so that the cured material has good insulation performance and arc resistance.
(2) it can reduce the exothermic peak temperature of epoxy resin curing reaction, reduce the linear expansion coefficient and shrinkage rate of the cured material, eliminate the internal stress of the cured material and prevent cracking.
(3) Corrosion resistance: silicon powder is not easy to react with other substances, and can not react with most acid and alkali. Its particles uniformly cover the surface of the object, and it has strong corrosion resistance.
(4) Reasonable particle size distribution, use can reduce and eliminate precipitation, stratification phenomenon; It can enhance the tensile strength and compressive strength of the cured material, improve the wear resistance, and increase the thermal conductivity of the cured material, increase the flame retardant performance.
(5) The silicon powder treated by silane coupling agent has good infiltration, good adsorption performance, is easy to mix, and no agglomeration phenomenon for all kinds of resins.
(6) Silicon powder as filler, added to the organic resin, not only improves the performance of the cured material but also reduces the cost of the product.
