The appearance of natural quartz sand was more prism, spherical, pure white, with high mechanical strength, interception capability, acid resistance is good. 

 Heyuan, Guangdong, wholesale distribution company of high purity natural quartz sand, SIO2 content as high as 99.7%, the production process: mineral processing, crushing, screening (second screening), water mill, cleaning (special requirements of pickling), drying and packaging. With hardness, good corrosion resistance, high density, high mechanical strength, ability to set pollution characteristics of the use of long lines, is an ideal material for chemical water treatment. 

 I refined the physical and chemical analysis of quartz sand filter results: 
 Analysis of data analysis, project identification project identification project identification data in data analysis 
 SiO2 content of 99% hydrochloric acid soluble bulk density and 0.4% 1.75t/m3 
 Mohs hardness of 7 degree of wear rate of 0.3% acid-resistant acid 
 Boiling point 2550 ℃ degree of fragmentation rate of 0.35% alkali Good alkali resistance 
 Ash melting point 1480 ℃ rate of 0.25% Zn content of 0.005% 
 2.67 43% share of the other metal content of porosity does not exceed the national drinking water standards 


 Quartz sand filter to play, just like water infiltration into the ground through the gravel as the suspension of the material that the water block down, mainly for those fine suspended solids. 
 Quartz sand as the filter material application: quartz sand combined with the filter container used to retain particles in water and other impurities in colloidal suspensions, and thus play a filter role. 
 Our quartz sand for other purposes: 

 Glass: flat glass, float glass, glass products (glass jars, glass bottles, glass, etc.), optical glass, glass fiber, glass apparatus, conductive glass, glass cloth and anti-rays of the main raw material of special glass. 
 Ceramics and refractories: billet porcelain and glazes, kilns with high silica brick, silica brick, and ordinary raw materials such as silicon carbide. 
 Metallurgy: silicon metal, silicon and silicon aluminum alloy and other raw materials or additives, flux. 
 Construction: Concrete, cementitious materials, road building materials, artificial marble, cement physical properties of test materials (ie cement standard sand) and so on. 
 Chemical: silicone compounds and water glass and other raw materials, sulfuric acid tower fillers, amorphous silica dioxide. 
 Machinery: sand casting the main raw material, abrasive material (sand, hard abrasive paper, sandpaper, emery cloth, etc.). 
 E: high-purity silicon metal, communication with optical fiber. 
 Rubber and plastic: packing (can improve wear resistance.) 
 Coatings: fillers (which can improve the coating durability.)
