Supply Jizhou quartz sand

Quartz sand filter water use is the most common media filter material, widely used, large range, it can be used for drinking water and industrial process water as well as various pools shaped ordinary quick filter and water filters, water purification machinery filter, multi-media filter, integrated water purifier. Quartz sand physical and chemical indicators? Quartz sand and Physical Performance Analysis (0.5 to 1.2, for example) Item Unit analysis Item Unit analysis of clay content of hydrochloric acid soluble rate 0.05% 0.02% Density g / cm3 2.66% Acid degree 98 Wear rate% porosity 0.03% 0.35% 43 broken rate capacity g / cm3 1.75% silica 99.3 Mohs hardness of 7.5 Technical Requirements 1, broken quartz sand and wear rate and the rate of not more than 1.5% (percentage by mass, the same below). 2, quartz sand should not be less than the density of 2.55g / cm3, the use of density with special requirements are excluded. 3, quartz sand should not contain visible dirt, mica and organic impurities, filter flooding fluid does not contain toxic substances. Light material content of clay content should not exceed 1%, density is less than 2g / cm3 should not exceed 0.2%. 4, quartz sand of the LOI should not exceed 0.7%. 5, quartz sand hydrochloric acid soluble rate should not exceed 3.5%. 1 quartz sand of particle size, particle size range in a variety of quartz sand filter, a particle size less than the specified lower limit should not exceed 3%, greater than the specified upper limit of the particle size should not exceed 2%. 2, the effective diameter quartz sand is determined by the use of units. Main purpose: valveless, water plants, sewage treatment plants. Inexpensive, long life cycle, high mechanical strength, not broken, other than natural quartz sand broken pure quartz sand long cycle 3-8 times, and the quality and stability filtered.
