Anti-settling silicon micro-powder
Anti-settling silicon micro-powder is produced by grinding high-purity natural quartz ore with iron-free pollution-free process and high-precision classification. It is a non-toxic, odorless, and pollution-free high-white mineral powder with excellent properties such as anti-settling effect, acid and alkali corrosion resistance, high insulation, low expansion, stable chemical properties, and high hardness.
Silicon micropowder has the characteristics of high hardness, high thermal conductivity, low linear thermal expansion coefficient, and good insulation performance. When used as filler in epoxy resin, it can enhance the hardness, heat resistance, wear resistance, and mechanical strength of composite materials, reduce the internal stress of cured products, prevent cracking and deformation of the products, and lower the temperature rise of electromechanical products.

3. Introduction to Anti-settling Silicon Micro-powder:
To address the urgent demand for anti-settling performance in silicon micropowder for specialized applications, our company has developed a unique processing technology that enhances the product's compressive, tensile, and impact strength. This improvement also optimizes the mechanical, electronic, and chemical properties of the mixture and filling system. Without compromising the original performance, the silicon micropowder now exhibits superior anti-settling properties, reduced viscosity, and improved fluidity, thereby increasing mechanical strength. The product effectively prevents delamination in curing systems and can be combined with epoxy resin and curing agents without accelerating or hindering their curing reaction rates, nor affecting performance during casting. This significantly improves the interfacial cross-linking effect between epoxy resin and silicon micropowder, ultimately reducing production costs and enhancing economic efficiency.
4. Brief Analysis of Characteristics and Properties of Anti-settling Silicon Micro-powder:
The surface treatment and particle size distribution of silicon micropowder, as well as the viscosity and gel time of the system, all affect the settling rate of silicon micropowder. Under certain conditions, a small amount of gaseous SiO2 can be added to reduce the settling rate of silicon micropowder, thereby better improving the product performance degradation caused by silicon micropowder settling.
Anti-settling silicon micro-powder is produced from premium natural quartz through our proprietary processing technology. This high-purity white powder transforms the molecular structure from ordered to disordered arrangement, exhibiting a colorless, odorless appearance with exceptional anti-settling properties. Key characteristics include:
1. The anti-sedimentation effect is improved.
2. Improve the compressive, tensile and impact strength of the product.
3. Shorten the vulcanization time of product, increase the output and save energy.
4. The demolding yield rate of the product is high.
5. Enhance the vibrancy of the product's surface color.
6. Most importantly, it can increase the filling capacity and reduce production costs.
