The unique physical and chemical properties of quartz sand make it a pivotal position in aviation, aerospace, electronics, machinery, and today’s rapidly developing IT industry, especially its intrinsic molecular chain structure, crystal shape and lattice changes. Regularity, it has high temperature resistance, small thermal expansion coefficient, high insulation, corrosion resistance, piezoelectric effect, resonance effect and its unique optical properties. Then, Xiaobian will introduce the use of quartz sand and the characteristics of quartz sand.
Use of quartz sand
Quartz sand is usually used as a filter material to intercept particulate impurities such as colloidal particles in the water. In the process, the tail water is filtered to remove pollutants, and the pollutants gradually increase through the quartz sand filter material. Ordinary quartz sand filter is mainly used for the treatment of sewage, generally no problem for three to five years, mainly to prevent the amount of quartz sand from decreasing. Contaminated water During processing, the dirt can be oxidized better by the quartz sand filter, which will degrade the contaminants in the sewage. The refined quartz sand filter is used for pure water treatment and is usually replaced in the filter for two to three years. Quartz sand encased by contaminants does not provide better filtration and new functions are replaced. It is currently the most widely used and most used clean water material in the water treatment industry.
Characteristics of quartz sand
1. Compact structure: The device integrates coagulation reaction, filtration and continuous cleaning. Simplified water treatment process, small footprint, simple structure, flexible and convenient installation and operation. The energy consumption and labor management costs of the multi-step process of raw water treatment are reduced, and the operation difficulty is reduced.
2, the effect of coagulation reaction is obvious: the application of coagulation reaction mechanism and settlement mechanism, effectively remove suspended solids and colloidal substances in water, is conducive to further reduce the effluent turbidity in the sand filter area.
3, continuous self-cleaning filter: filter media automatically cycle, continuous cleaning, backwash without stopping.
4. To reduce the suspended solids (SS) content of raw water: With the micro-flocculation device, various industrial water, urban domestic sewage and industrial water are used as the reuse water, and the removal rate is ≥ 90% to achieve perfect filtering effect.
5, selected materials, long service life.
The use of quartz sand
1. Glass for the use of high-purity quartz sand: flat glass, float glass, glass products (glass cans, glass bottles, glass tubes, etc.), optical glass, glass fiber, glass instruments, conductive glass, glass cloth, and special rays The main raw materials such as glass
2. Electronic use of high-purity quartz sand: high-purity metal silicon, communication fiber, etc.
3, the use of high-purity quartz sand rubber, plastic: filler (can improve wear resistance)
4. Coatings for the use of high-purity quartz sand: Fillers (can improve the weatherability of coatings). 9. Metallurgical industry: Raw materials or additives for silicon metal, silicon-iron alloy and silicon aluminum alloy, flux X, aviation, aerospace: its intrinsic molecules The chain structure, crystal shape, and crystal lattice variation pattern make it have high temperature resistance, small thermal expansion coefficient, high insulation, corrosion resistance, piezoelectric effect, resonance effect, and its unique optical characteristics.
5. Ceramics and refractories used for high-purity quartz sand: raw materials and glazes for porcelain, raw materials for high-silica bricks for furnaces, ordinary silicon bricks, and silicon carbide. Metallurgy: raw materials or additives for silicon metal, ferrosilicon alloy, silicon aluminum alloy, flux, flux, concrete, concrete, road building materials, artificial marble, cement physical properties test materials
6. Machines for the use of high-purity quartz sand: The main raw materials for casting sand, abrasive materials (blasting, hard abrasive paper, sandpaper, emery cloth, etc.)
