Quartz sand Scope: Our company produces ordinary quartz sand filter is made from natural quartz ore, crushing, screening, washing, drying, secondary screening is made. More angular, almost spherical, small impurity content, high mechanical strength, interception capability, chemical stability. Widely used in drinking water, sewage and industrial water. Quartz sand technical requirements: 1, quartz sand crushing and wear rate and the rate should not exceed 1.5% (percentage by mass, the same below). 2, quartz sand density of not less than 2.55g/cm3, the use of special requirements for density are excluded. 3, quartz sand should be free of visible dirt, mica and organic impurities, filter the water extract does not contain toxic substances. Light material content, clay content should not exceed 1%, less than 2g/cm3 density should not exceed 0.2%. 4, quartz sand of loss on ignition shall not exceed 0.7%. 5, quartz sand of hydrochloric acid soluble rate should not exceed 3.5%. Quartz sand particle size: 1, size range in a variety of quartz sand, and less than the specified lower limit of the particle size should not exceed 3%, greater than the specified maximum particle size should not exceed 2%. 2, the effective diameter quartz sand is determined by using the unit.
