In silica sand processing , the unique physical and chemical characteristics of silica sand make silica sand play an important role in the aviation, aerospace, electronics, machinery and IT industry, especially in its internal molecular chain structure, crystal shape and lattice change law, which makes it have high temperature resistance, small thermal expansion coefficient, high insulation, corrosion resistance, piezoelectric effect, resonance effect and so on. Its unique optical properties play an increasingly important role in many high-tech products. Silica sand is an important industrial mineral raw material, non-chemical dangerous goods, widely used in glass, casting, ceramics and refractories, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical industry, plastics, rubber, abrasives and other industries. It can be transported by air, by train and by water. 1.Glass: Flat glass, float glass, glass products (glass cans, glass bottles, glass tubes,
