According to my plant perennial supply of quartz sand as a filter of experience, summed up a few suggestions for early adopters of quartz sand, quartz sand there are certain technical requirements are as follows: 1, clay content should not exceed 1%, the density light material content is less than 2g / cm3 should not exceed 0.2% (ministerial standard). 2, quartz sand particle size with the management, the appearance of more angular monologue shiny crystals. Single or double filter size range, typically 0.5-1.2mm. Three filter particle size range, typically 0.5-0.8mm. 3, the lower limit of particle size less than the specified size range by weight of not more than 3%, greater than the specified upper limit size of not more than 2%. 4, mechanical strength, and wear rate of the crushing rate and should not exceed 1.5%. 5, chemically stable, free of visible dirt, mica and organic impurities, filter the water extract does not contain toxic substances. 6, should not be less than the density of quartz sand 2.55g / cm3. (The use of special requirements for density except). 7, quartz gravel supporting layer of particle size range, typically 2-4,4-8,8-16,16-32 and 32-64mm. 8, quartz sand burning weight loss should not exceed 0.7%, hydrochloric acid soluble rate should not exceed 1.5%. The above points are a few suggestions for the initial users; hope to help you choose the high quality quartz sand products. General construction of quartz sand, the main product quality and quality, complete model, with high temperatures, high melting point, good acid and alkali, insulation effect, thermal and chemical properties of a strong anisotropy, the physical properties of stable pure quartz sand, with a texture, color pure quartz sand smooth, delicate jade like silicon, and can be used as building cement concrete, sealing against leakage of new materials, mortar, concrete building with a major factor in improving the application of acid resistance, extended service life and so on. "Cost" has been advocated by people like the same floor applications, while some manufacturers focus only on low-cost and ignore the quality of this concept, the application of quartz sand production is higher than the self-leveling epoxy floor price to Ping, so now the case in the past. The fundamental reason is the high cost of materials, construction techniques and more complex. Quartz sand are a non-renewable resources, non-metallic, excellent floor would cost an increasing trend, only the rational use of every minute of quartz sand resources will make a good product for a long time to survive. Quartz sand in wastewater treatment which are indispensable role, but the problem with the sewage drain quartz sand are present, most enterprises have encountered, thus preventing the loss of quartz sand is very important. We must first set up in the sewage treatment tank interception facilities, and secondly to set the filter at each stage, to prevent the loss, the last to go with someone check, processing and maintenance 1-2 quartz sand, quartz sand in order to prevent the loss. Only prevent their loss will be thoroughly treated sewage steel with quartz sand, which we need to continue to explore the use of quartz sand process. Quartz sand filling in the fuse, the aim is to enhance the ability to fuse interrupter. Because quartz has a high thermal conductivity and insulating performance, and the arc has a large contact area, thus facilitating absorption arc energy, it is possible to rapidly cool the arc. Waterworks quartz sand, Daxing quartz sand, quartz sand filter water purification materials provided by Henan Spirit Limited. Henan Spirit Water Material Co. (www.gyssjs.com) strong, credible, in Zhengzhou, Henan water treatment chemicals and other industries has accumulated a large number of loyal customers.
