20-40 mesh silican sand with 99% silicon concent for industrial mineral raw material

Slican Sand is quartz sand, it is an important industrial mineral raw material, widely used in many fields. Its main uses include:

1. Glass manufacturing. Silica sand is the main raw material of flat glass, float glass, glass products (such as glass jars, bottles, tubes, etc.), optical glass, glass fiber, glass instruments, conductive glass and special ray-resistant glass.

2. Ceramics and refractories. Silica sand is used in the manufacture of porcelain embryos and glazes, and as a raw material for refractory materials such as high-silicon bricks, ordinary silicon bricks and silicon carbide for kilns.

3. Metallurgical industry. Silica sand is used as raw materials, additives and fluxes for silicon metal, ferrosilicon alloy and silicon aluminum alloy.

4. Building materials. Silica sand enhances the hardness and strength of materials in building materials, accelerates the solidification time of materials, and improves the quality and performance of building materials.

5 Chemical industry. Silica sand is used in the manufacture of silicon compounds, water glass, etc., as well as the filling of sulfuric acid towers and amorphous silica powder.

6. Machinery industry. Silicon sand is the main raw material of casting sand, and it is also a part of abrasive materials (such as sandblasting, hard abrasive paper, sandpaper, emery cloth, etc.).

7. Electronic industry. Silica sand is used in the manufacture of high purity metal silicon, communication optical fiber and so on.

8. Rubber and plastics industry. Silica sand is used as filler to improve the wear resistance of products.

9. Coating industry. Silica sand as filler enhances the acid resistance of the coating.

10. Sports venues. Quartz sand is used for artificial turf, such as track and field, football field, golf course and other artificial venues.

Other uses. Silica sand is also used for sand cleaning, rust removal, peel removal treatment, and as an additive to heavy concrete and blast furnace refractories to increase their wear resistance, high temperature resistance and erosion resistance.
