Weijing Li company website _http: //www.zhhy888.com: http: //www.zhhy888. com / / _ Business QQ_303949886 Beijing North Branch Green Clean Environmental Protection Technology Co., Ltd. good mood every day to treat each day can be divided quartz sand refined quartz sand, ordinary quartz sand, high-purity quartz and fused silica sand. Refining quartz sand: The quartz ore deep underground, by mechanical crushing, rolling washing crushing, sieving, acid washing, washing, drying, from the second sub-screen. More angular, high purity, free of impurities, high mechanical strength, chemical stability. Ordinary quartz sand: the use of natural quartz deposits by mechanical crushing, rolling washing crushing, washing, drying and sieving made less impurities. The factory production of quartz sand filter water treatment in strict accordance with national standards of production processing filter (CJ / 43-2005). Quartz sand is the use of silicon material to the main natural quartz ore, by crushing, washing, drying, secondary screening is made. The color white, small impurity content, more angular, high density, high mechanical strength, interception capability, anti-erosion filtration and washing process, chemical stability, water quality and stability, non-blocking, non-blocking, than the sea Sand long life cycle (1-2 cycles), is an ideal material for water purification in. Quality quartz sand quartz sandstone ore products from natural, processed by complex physical processes from silica content higher than 99%. Its high silicon content determines its hardness, since this feature quartz sand is also used in the construction industry in recent years has also been used in high quartz sand aviation industry, electronic industry and so on. With the continued development of quartz sand finishing, we believe in the future of quartz sand will enter more and more high-end industries, realize their own proper value quartz sand. High purity quartz sand SiO2≥99.5-99.9% Fe2O3≤0.005%, using high-quality natural quartz stone, carefully selected, fine processing. Mainly used in the manufacture of glass, refractories, smelting ferrosilicon, metallurgical flux, ceramics, abrasive materials, quartz sand casting molding, etc., its use in the construction of a strong acid etching medium capacity for extracting acid and acid of concrete mortar. With 5-480 mesh size range, according to user requirements, the appearance of white or crystals. Main purpose: Senior glass and glass products, refractories, smelting stone, precision casting, grinding wheel and other materials. (Mm is millimeters)
