Quartz sand quartz sand is the use of natural quartz ore as raw material, processed by crushing, washing fine sieve, is currently the most widely used in the water treatment industry, the largest amount of water purification materials, free of impurities, compression-resistant grinding, high mechanical strength, chemical stability, interception capability, high efficiency, long life cycle, suitable for single, double filtration ponds, filters and ion exchange, the targets are met (CJ/T43- 1999) standards. Processing refined quartz sand, pure quartz sand, acid treatment agent, ordinary quartz sand, which can meet the different needs of the user. Common specifications :0.5-1 .0 mm 0.6-1.2mm 1-2mm 2-4mm 4-8mm 8-16mm 16-32mm natural quartz sand quartz ore, crushing, screening, washing and other processing by. Appearance of a multi-prism, spherical, pure white, with a high mechanical strength, interception capability, good acid resistance. Quartz sand quartz sand is the use of natural quartz ore, crushing, washing, screening, pickling, drying, secondary screening from a water filter; commonly used quartz sand, there are two main , ordinary quartz sand, the other is refined pickling sand quartz sand: hardness, corrosion resistance, high density, high mechanical strength, the contained sewage capacity line long life cycle, chemical an ideal material for water treatment. Quartz sand to act as a filter, like water through the sand to infiltrate underground, blocking the suspended matter in the water down, mainly for those fine suspended solids. Classification of quartz sand and quartz sand as filter material applications, quartz sand filter container combination for the interception of suspended solids in water colloidal particles of impurities, which act as a filter. Can be divided into the following categories: 1. Ordinary quartz sand: mainly used in sewage treatment, 2035 no problem, as long as to prevent the loss of quartz sand, pollution does not matter, because the sewage treatment, sludge can be aerobic or anaerobic respiration, the degradation of pollutants in sewage. Refined quartz sand: used in water treatment, sand filter, 2-3 years to be replaced, usually contaminated pollutants wrap quartz sand you can not play a very good filtering effect , only to be replaced. Quartz sand by so9001-2000 quality system certification. Are stable in neutral and value in the range of acidic water, but slightly soluble in alkaline water, chemical water treatment SiO2 increment does not exceed 2 mg / L. Common specifications :0.5-1 .0 mm 0.6-1.2mm 0.8-1.6mm 1.0-2.0mm 2.0-4.0mm 4.0-8.0mm 8.0-16mm 16-32m refined quartz sand filter analysis of physical and chemical analysis project identification data analysis project identification data analysis project identification data SiO2 content of 99.5% bulk density 1.75t/m3 Hydrochloric acid soluble rate 0.4% 7 Mohs hardness wear rate of 0.3% Acid resistance resistant to acid boiling point 2550 ℃ crushing rate of 0.35% alkali alkali resistance good melting point of 1750 ° C ash rate of 0.25% Zn content of 0.005% proportion 2.65 void ratio 43% metal content does not exceed the national drinking water standards
