Application of Molten Silicon Micropowder in Six Major Industries (II)

4、 Application of silicon micro powder as polishing and washing abrasive in the industry

With the development of modern technology, higher and more precise surface treatment of materials is also required, and its application in the abrasive industry is becoming increasingly widespread. Silicon micro powder, due to its nearly circular particles, is prepared by ultrafine and graded ultrafine powder. After modification treatment, it is a good washing abrasive for metal parts. If used in washing bearings, the smoothness can reach 3.0 or above, which is superior to similar products in displays.

In addition, it is used for polishing in the semiconductor industry, precision valves, hard disks, magnetic heads, and automotive polishing agents, all of which have good effects.

5、 Application of Silicon Micropowder in Coatings

By utilizing the unique functionality of silicon micro powder, it can replace precipitated barium sulfate and talc powder in the formulation of mixed paints, primers, and anti stripping paints (with an addition amount of 6-15%). It not only plays a filling and capacity increasing role, but also has significant effects on improving paint fineness, leveling performance, paint film hardness, shortening paint grinding time, water resistance, rust prevention, anti-corrosion performance, pigment dispersibility, and paint storage stability. Furthermore, the melt film coating composed of silicon micro powder, water, surfactant, and water in a certain proportion has become a high-quality coating in precision casting due to its low viscosity, no sagging phenomenon, and convenient use.

Used for cabinet decoration, it has excellent decorative effect and corrosion resistance.

6、 Application of Silicon Micropowder in Electrical Insulation Packaging Materials

Electrical grade silicon micro powder is an active silicon micro powder used as an epoxy resin insulation sealing filler for electrical products. It not only significantly increases the filling amount, but more importantly, it plays a beneficial role in reducing the viscosity of the mixture system, improving processing performance, enhancing the permeability of the mixture to high-voltage electrical coils, reducing the expansion coefficient and shrinkage rate of the cured material, feeding the thermal tension difference between the mixture and the coil, and improving the thermal, electrical, and mechanical properties of the cured material.
