Henan Yu Tai Water Material Co., Ltd. Jinhua Branch to provide you with a variety of quartz sand, can be particularly produced according to customer requirements. Quartz sand Technical Requirements 1) Mechanical strength Yongkang treatment with quartz sand, broken rate and the rate of wear and should not exceed 1.5% (percentage by weight). 2) chemical stability, free of visible dirt, mica and organic impurities, filter flooding fluid does not contain toxic substances. 3) not less than the density of quartz sand 2.55g / cm3. (The use of special requirements for density except). 4) quartz sand burning weight loss should not exceed 0.7% hydrochloric acid soluble rate should not exceed 1.5% (ministerial standard). 5) The clay content should not exceed 1% of Yongkang treatment with quartz sand, density less than the content of 2g / cm3 of light materials should not exceed 0.2% (ministerial standard). 6) particle size with the management, the appearance of more angular monologue shiny crystals. Particle size range of single or dual-media Yongkang treatment with quartz sand, typically 0.5-1.2mm. Three-filter particle size range, typically 0.5-0.8mm. 7) size range smaller than the specified lower limit of the particle size, by weight, not more than 3% greater than the specified upper limit of the particle size of not more than 2%. 8) size range quartz gravel supporting layer, typically 2-4,4-8,8-16,16-32 and 32-64mm (ministerial standard). It can only be replaced. Treatment with quartz sand, sand forever 康石英, Yu Tai Yu-tai purification by the Gongyi City Water Material Co., Ltd. Jinhua Branch provided.
