Quartz sand is a natural quartz ore as raw material, crushing, washing fine sieve and processed, is currently the most widely used in water treatment industry, the largest water purification materials, free of impurities, compression wear, mechanical strength high chemical stability, and cutting pollution capacity, high efficiency, long life cycle, applicable in single-layer, double-filtration ponds, filters and ion exchange, all targets were achieved (CJ/T43-2005) standard. The processing of refined quartz sand, pure quartz sand, acid treatment agent, quartz sand, to meet the needs of different users. Common Specifications :0.5-1 .0 mm0.6-1.2mm1-such as 2 mm2-4mm4-8mm8-16mm16-32mm. What is quartz sand, natural quartz ore by crushing, screening, washing and other processing by the. The appearance of multi-prism, spherical, pure white, with a high mechanical strength, sewage interception capability, and good acid resistance. Quartz sand quartz sand filter is the use of natural quartz ore by crushing, washing, screening, pickling, drying, and the second filter made of a water treatment filter; common quartz sand, there are two main a common quartz sand, the other is refined pickling sand. Quartz sand: hardness, good corrosion resistance, high density, high mechanical strength, sewage interception capability, long cycle characteristics, an ideal material for chemical water treatment. Play a filtering role of quartz sand, like water through sand and gravel seep into the ground, blocking off the water, suspended solids, mainly for those fine suspended solids. Quartz sand classification and application of quartz sand in the field of application as a filter material, quartz sand combined with the filter container for interception water suspended matter colloid particles, such as impurities, which play a filtering role. Can be divided into the following categories: (1) ordinary quartz sand filter: mainly used in sewage treatment, with 2035 no problem, as long as to prevent the loss of quartz sand on the line, is contaminated does not matter, because sewage treatment, sludge can be aerobic or anaerobic respiration, the degradation of pollutants in the sewage. 2 refined quartz sand: used in water treatment, sand filters, usually 2-3 years to be replaced, surround the quartz sand is often contaminated, contaminants can no longer play a filtering role , only to be replaced. Quartz sand Iso9001-2000 quality system certification. High-definition picture of refined quartz sand are stable in neutral and value in the range of acidic water, slightly soluble in alkaline water, chemical water treatment the SiO2 increment does not exceed 2 mg / L. Common Specifications :0.5-1 .0 mm0.6-1.2mm0.8-1.6mm1.0-2.0mm2.0-4.0mm4.0-8.0mm8.0-16mm16-32m refined quartz sand physical and chemical analysis: analysis of the project identification data analysis, project identification data analysis, project identification data SiO2 content of 99.5% bulk density 1.75t/m3 0.4% of the rate of hydrochloric acid soluble Mohs hardness of the wear rate of 0.3% acid resistant to acid boiling point 2550 ° C broken rate of 0.35% alkali-alkali resistance melting point 1750 ° C ash rate 0.25% Zn content of 0.005% the proportion of 2.65 porosity 43% metal content does not exceed national standards for drinking water applications: quartz sand is an important industrial mineral raw materials, non-hazardous chemicals, widely used in glass casting, ceramics and refractories, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemicals, plastics, rubber, abrasive and other industries. May Automotive, train transportation. As follows: Glass: flat glass, float glass, glass products (glass jars, glass bottles, glass tubes, etc.), optical glass, glass fiber, glass apparatus, conductive glass, glass cloth and anti-rays specialty glass, etc. The main raw material. , Ceramics and refractories: the billet and glaze of the porcelain furnace with a high silica common silica and silicon carbide and other raw materials. , Metallurgy: silicon metal, ferrosilicon alloy and silicon aluminum alloys and other raw materials or additives, flux. Construction: concrete, cementitious material, road building materials, artificial marble, cement, physical performance test materials (ie cement standard sand). Chemical: silicon compounds and water glass and other raw materials, sulfuric acid tower filler, amorphous silicon dioxide. Machinery: the main raw material for foundry sand, abrasive material (sand blasting, hard abrasive paper, sand paper, emery cloth, etc.). Electronics: high purity silicon metal, communication optical fiber. Eight, rubber, plastics: filler (which can improve the wear resistance). Nine, paint: fillers (can increase the acid resistance of the coating). 10, aviation, space: its intrinsic molecular chain structure, the crystal shape and the lattice variation, it has high temperature, thermal expansion coefficient is small, highly insulated, corrosion resistance, piezoelectric effect, resonance effect, as well as its unique optical properties. The quartz sand production base in Hebei the Lingshou processing quartz sand base, the manufacturers: the Lingshou BAIXIN quartz sand processing plant Lingshou quartz sand processing plant in Gongyi City, Henan new Water Industry Co., Ltd. quartz sand packing and storage: quartz sand woven bag, net weight 50KG, 25KG or t-bags. Quartz sand should not be stacked and supporting materials and other media with Quartz sand and other media should not be together with other toxic and hazardous materials contaminated items stacked. Can not be missed days of storage, storage of dust pollution prevention, the general warranty period of ten years. Quartz sand filter criteria: the Ministry of Construction of the quartz sand ministerial standards: natural quartz deposits as raw materials, the mining, crushing, washing, screening and processing (by pickling of high-purity quartz sand), high mechanical strength, chemical stable performance in line with the standards of the Ministry of Construction (CJ/T43-1999). Quartz sand quartz sand processing process industry raw material grade is getting lower and lower to meet the industrial needs through the beneficiation process to improve its taste. Mainly in the following purification methods: 1, scrub off the mud. Scrub refers to the use of mechanical force and grit grinding stripping force to remove the quartz sand surface film of iron, bonded and clay impurities, minerals and further SAA unpaired monomer mineral aggregates, then the grading operations to achieve further purification of quartz the effect of the sand. Stick friction washing and mechanical scrubbing. The main factors affecting the scrubbing effect of the structural characteristics of the scrubbing machines and configurations; a secondary factor for the scrub time, scrub concentration (scrub concentration is generally 50% -60% is appropriate). 2, the magnetic separation. The magnetic separation is mainly used to remove the quartz sand in the magnetic minerals, such as by the strong magnetic machine to remove weakly magnetic mineral hematite, limonite, biotite, and strong magnetic minerals such as magnetite by low intensity magnetic separation machine removed. 3, the flotation. Flotation is used to remove the quartz sand, feldspar, mica and other magnetic separation can not be removed impurities, and further enhance its purity. 4, the acid leaching. Acid leaching is the use of quartz does not dissolve in acid (HF acid excluded), and other impurities in minerals can be acid dissolution of the characteristics can be further purified on quartz. 5, microbial leaching. Refers to the use of microbial leaching in addition to the quartz sand particles the surface film of iron or disseminated iron, which is a newly developed iron removal technology.
