Quartz sand has unique physical and chemical properties that make it play an important role in the aviation, aerospace, electronics, machinery and rapidly growing information technology industries. In particular, its internal crystal morphology, molecular chain structure and lattice change rules make it have piezoelectric effect, corrosion resistance, high insulation, low thermal expansion coefficient, high temperature resistance, resonance effect and unique optical properties. It is used in many high-tech products. play an increasingly important role.
quartz sand
1. Glass industry. The main raw materials include flat glass, float glass, glass products, optical glass, glass fiber, glass instruments, conductive glass, glass cloth and special radiation-proof glass.
2. Ceramics. As well as ceramic refractory porcelain blanks and glazes, high silica bricks, ordinary silica bricks, silicon carbide and other raw materials for kilns. Raw materials or additives for metallurgical silicon, ferrosilicon alloys, and silicon-aluminum alloys, such as flux concrete, cementitious materials, road construction materials, artificial marble, cement physical property testing materials, etc.
3. Chemical industry. Quartz sand is suitable for sand cleaning, rust removal, strengthening, molding, stress relief, surface cleaning and painting of various profiles, roughness pretreatment before electroplating, stone cutting, magnetic shot casting, and as a refractory material for heavy concrete and blast furnaces. Additives to increase wear resistance and high temperature resistance in the fields of casting, forging, machinery, metallurgy, heat treatment, steel structures, grid structures, containers, ships, repairs, bridges, mines and other fields. The surface treatment of granite and marble uses high-quality quartz sand as raw material and is specially designed and produced for sports venues. It has the characteristics of high hardness, high specific gravity, uniform particle size, small edges and corners, and natural color. It does little damage to artificial turf and can protect the grass hair and make the turf more durable. It is used in many domestic university gymnasiums. Quartz sand is an ideal material for modern track and field, football fields, golf courses and other artificial venues.
4. Water treatment filter materials. Since the particle size of the quartz sand in the three-layer filter bed is smaller than that of the double-layer filter bed, and there is a layer of finer heavy anthracite filter material under the quartz sand layer, under the same other conditions or even when the filtration speed is high, the three-layer filter bed The quality of filtered water is better than that of double-layer filter bed. When using quartz sand, try to use it together.
5. Quartz sand filter. The sewage tailwater enters the bottom of the filter through the water inlet pipe. After being evenly distributed by the water distributor, it passes through the filter material layer from top to bottom. The tail water is filtered to remove pollutants in the water. During this process, the content of pollutants in the quartz sand filter material increases at the same time, and the level of pollutants in the lower filter material layer is higher than that in the upper filter material layer. At this time, lift the lower quartz sand filter material to the sand washer on the top of the filter for cleaning by turning on the air lift pump located in the center of the filter. The cleaned sand is returned to the filter bed, while the pollutants produced by cleaning are discharged. The quartz sand filter material moves from top to bottom under the action of the lifting pump, which can stir the tail water. The filter material in the filter can be cleaned in time and has strong resistance to pollution load impact. Due to the special internal structure and operating characteristics of the quartz sand filter, coagulation, clarification and filtration can all be completed in the same tank.
