  • Detail

Quartz sand is a quartz particle formed by crushing quartz stone. Its color is milky white, or colorless and translucent. Its Mohs hardness is 7. It is an important industrial mineral raw material

the unique physical and chemical properties of quartz sand make it play an important role in aviation, aerospace, electronics, machinery, and today's rapidly developing IT industry. Especially its internal molecular chain structure, crystal shape and lattice change law make it have high temperature resistance, low coefficient of thermal expansion, high insulation, corrosion resistance, piezoelectric effect, resonance effect and its unique optical properties. Then, let's introduce the use and characteristics of quartz sand

use of quartz sand

quartz sand is usually used as filter material to intercept suspended solids, colloids and other particle impurities in the filter. In this process, the tail water is filtered to remove pollutants, and the pollutants gradually increase through the quartz sand filter material. Ordinary quartz sand filter material is mainly used for sewage treatment. Generally, it can be used for three to five years. It is mainly to prevent the amount of quartz sand from decreasing. In the treatment of polluted water, dirt can be better oxidized through quartz sand filter material, which will degrade pollutants in sewage. Refined quartz sand filter material is used for purified water treatment, and the filter generally needs to be replaced once every two to three years. The quartz sand wrapped by pollutants cannot play a better role in filtration, and the function is replaced with a new one. At present, it is the most widely used water purification material in the water treatment industry

characteristics of quartz sand

1. Compact structure: the equipment integrates coagulation reaction, filtration and continuous cleaning. The water treatment process is simplified, the floor area is small, the structure is simple, and the installation and operation are flexible and convenient. The energy consumption and labor management cost of multiple links of raw water treatment process are reduced, and the operation difficulty is reduced

2. Obvious coagulation reaction effect: the application of coagulation reaction mechanism and sedimentation mechanism can effectively remove suspended solids and colloidal substances in the water, which is conducive to further reducing the turbidity of effluent in the sand filtration area

3. Continuous self-cleaning filtration: the filter medium is automatically circulated and continuously cleaned without shutdown for backwashing

4. Reduce the suspended solids (SS) content of raw water: with the micro flocculation device, all kinds of industrial water, urban domestic sewage and industrial water are used as reuse water, and the removal rate ≥ 90%, achieving perfect filtration effect

5. Special material, long service life

the use of quartz sand

1. 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 ray proof special glass, etc.

2. The use of high-purity quartz sand: electronics of high-purity metallic silicon, optical fiber for communication, etc.

3. The use of high-purity quartz sand: rubber Plastics: fillers (which can improve wear resistance)

4. Coatings for the use of high-purity quartz sand: fillers (which can improve the weather resistance of coatings) IX. metallurgical industry: raw materials or additives of silicon metal, ferrosilicon alloy and silicon aluminum alloy, flux X. aviation and aerospace: its internal sub chain structure, crystal shape and lattice change law, so that it has high temperature resistance, low coefficient of thermal expansion, high insulation, corrosion resistance, piezoelectric effect Resonance effect and its unique optical properties

5. Ceramics and refractories for the use of high-purity quartz sand: embryo and glaze of porcelain, raw materials of high silicon bricks, ordinary silicon bricks and silicon carbide for kilns. Metallurgy: raw materials or additives, fluxes of silicon metal, ferrosilicon alloy, silicon aluminum alloy, etc. III. Construction: concrete [1], cementitious materials, road building materials, artificial marble, cement physical property testing materials (i.e. cement standard sand), etc.

6. Machinery for the use of high-purity quartz sand: the main raw materials of casting molding sand, Abrasive materials (sand blasting, hard abrasive paper, sandpaper, abrasive cloth, etc.)

editor's summary: This is the introduction about the use of quartz sand and the characteristics of quartz sand. I hope it will be helpful to you. If you want to know more about it, you can pay attention to the information
