First, the nature of quartz sand, raw materials and applications: quartz sand in China is currently using a very wide range of media. I produced the quartz sand, natural quartz ore crushing, screening, washing made diamond shape, color white, no impurities, the density of 2.66, the silicon content of 99.9%, the mechanical strength of 7.5 degrees. At present, some areas use natural river sand, sea sand to do media, although the low cost, but the use of short cycle, mechanical strength poor, broken easily. Quartz sand 3-4 times longer than the natural sand cycle. The filtered water quality and stability in the long run the economic perspective, quartz sand than the river sand and sea sand is much lower. Quartz sand filter is mainly used in sewage treatment, three to five years with no problem, as long as the quartz sand to prevent the loss of the line, is contaminated does not matter, because the sewage treatment sludge can be aerobic or anaerobic respiration, the wastewater The degradation of pollutants. Widely used in glass, foundry, ceramics and refractories, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemicals, plastics, rubber, abrasive, media and other industries. Second, the technical indicators: Item Unit analysis Item Unit analysis of silicon oxide Mohs hardness of 99.9% clay content of 7.5% hydrochloric acid soluble rate 0.05% 0.02 specific gravity g / c 2.66 Acid resistance wear rate% 0.03% 98% porosity? 43 Broken rate% 0.35 density g / c 1.75 Second, quartz sand What precautions:? 1, quartz sand filter and a triangular supporting material during transport and storage bags should prevent damage to avoid leakage or mixed with debris . 2, quartz sand not with supporting materials and other media, material stacked together. 3, quartz sand must be filled in before the filter (filter) inside cleaned. 4, to lay evenly on each filter, when it reaches the calibration thickness must be raked media. 5, quartz sand long run there will be wear and tear, improper operation will run if material, to that end need to regularly check the filter status and, if the case of loss of material need to replenish. Note: If the running time is too long quartz sand, water quality and long-term is unclear, or filter layer occurs turbostratic, you need to replace or re-distribution change.
