Quartz sand according to the different raw materials and SiO2 content, can be divided into a number of different kinds of products, so its application range is very wide, in glass, chemical, machinery, electronics and other industries have its role performance, mainly has the following uses:
1, ceramics and refractory materials: used for porcelain embryo and glaze, kiln with high silicon bricks, silicon bricks and silicon carbide and other materials.
2, glass: Quartz sand can be used as flat glass, float glass, glass products (glass jars, glass bottles, glass tubes, etc.), optical glass, glass fiber, glass instruments, conductive glass, glass cloth and special anti-ray glass materials.
3, metallurgy: silicon metal, ferrosilicon alloy and silicon aluminum alloy and other materials or additives, flux, can be used as the metal surface rust removal shot blasting, sandblasting.
4, construction: concrete, cementing materials, road construction materials, artificial marble, cement physical function inspection materials (i.e., cement sand), magnesite manhole cover, etc.
5, chemical industry: quartz sand can be used for silicon compounds and water glass and other materials, sulfuric acid tower filler, amorphous silica powder.
6, machinery: the essential materials of casting sand, grinding materials (sandblasting, hard grinding paper, sandpaper, emery cloth, etc.).
7, electronics and aerospace: its internal molecular chain structure, crystal shape and lattice change rules, so that it has high temperature resistance, small thermal expansion coefficient, high insulation, corrosion resistance, piezoelectric effect, resonance effect and its optical properties, can be used in electronic fillers, high purity metal silicon, communication fiber, circuit board, aerospace industry.
8, Rubber and plastics: fillers (forward wear resistance).
Nine, paint: can advance paint acid resistance.
