Ultrafine silicon powder can be used for PVC flooring, polyethylene and polypropylene films and other plastics, as well as electrical insulation materials. Polyvinyl chloride floor tiles added with silicon powder can improve the wear resistance of the product. In the PVC floor, a floor made of quartz powder with a fineness of 320 mesh and a filling amount of 160-180 pieces can meet the requirements of gb4085-83. The floor surface has good smoothness and good scratch resistance.

When the filling amount of 400 mesh quartz powder is 10%-15%, compared with other fillers, the viscosity is lower, the fluidity is better, the processing performance is better, and the product is suitable for extrusion molding. The polyethylene (pe) film is filled with silicon micropowder with a specific surface area greater than 600 mesh and high activity to improve the physical and chemical properties and optical properties of the product. Filling with polypropylene can improve the mechanical properties of the product. Yu Zhiwei studied the application of powdered quartz in polyethylene film. After ultra-fine, grading, purification and surface modification, powdered quartz was filled into polyethylene film. The use of quartz has the effect of blocking infrared rays and slowing the heat of plastic greenhouses. Loss, improve its thermal insulation performance.

When the addition amount of ultrafine quartz powder is 8%-12%, the mechanical properties of the polyethylene film are close to that of the pure resin film, exceeding. In epoxy molding compounds, high-purity silica powder is the main raw material. Because silica has stable physical and chemical properties, good light transmission and linear expansion, and excellent high-temperature performance, silica is Epoxy molding compound filling material is also the substrate material of semiconductor integrated circuit.

The above is a small series, telling you about the application of ultra-fine silicon powder in plastics, rubber and coatings, you can briefly understand. The content is for reference only, please contact us if you need to understand.
