Nowadays there are still a lot of people for the silicon powder of some basic information is not understood, so as a manufacturer, it is also necessary for us to briefly explain, in fact, silicon powder is a new raw material, the appearance of grey or pure white powder, refractoriness>1600 ℃. Bulk density: 200-250kg/m³. Widely used in the refractory industry.
It has an important role in the improvement of unshaped refractories, and can replace pure alumina mud as refractory materials. Silica powder should be stored in a dry, rain-proof, sun-proof environment. Micro-silica powder will agglomerate and lose its activity when it meets water, and prolonged exposure to the sun is strictly prohibited to prevent the bag from weathering, resulting in product spillage. In short, it is good insulation, of course, due to the high purity of silica powder, low impurity content, stable performance, excellent electrical insulation properties, hardened products have good insulation properties and arc resistance.
The use of silicon powder can reduce the exothermic peak temperature of the epoxy resin curing reaction, reduce the coefficient of linear expansion and shrinkage of the cured material, eliminate the internal stress of the cured material to prevent cracking. Of course, silicon powder also has good corrosion resistance. Silica powder is not easy to react with other substances, and does not react chemically with most acids and alkalis. The particles cover the surface of the object uniformly and have strong corrosion resistance.
In addition, reasonable particle grading can be carried out to reduce and eliminate precipitation and delamination in the process of use; it can improve the tensile and compressive strength of the cured object, improve the abrasion resistance, and increase the thermal conductivity of the cured object. Flame retardant performance. Silica micropowder treated with silane coupling agent has good wettability for various resins, good adsorption performance, easy to mix, no lumps. Silica vapour as a filler added to the resin, both to improve the performance of the cured material, but also to reduce the cost of the product.
