Yuxin quartz sand is made from natural quartz ore crushing screening washing and drying pickling secondary screening made of a water filter, the main component of quartz sand is silica containing iron oxide, clay and organic impurities quartz sand appearance of multi-prism, spherical plain white hardness, good corrosion resistance high mechanical strength and density contained sewage capacity long line cycle characteristics is an ideal material for chemical water treatment filtration in single, double pools, filters and ion exchange applicable its targets were reached CJ / T43-2005 standards.

The technical requirements of quartz sand

Broken quartz sand and wear rate and the rate of not more than 1.5 percent by mass, the same below.
Quartz sand should not be less than the density of 2.55g / cm3 density use special requirements are excluded.
Quartz sand should not contain visible dirt, mica and organic impurities filter the water extract does not contain toxic substances. Clay content should not be greater than the content of a light material density is less than 2g / cm3 should not exceed 0.2.

Our national hundred electricity sector, factories, enterprises and units and other forces dedicated transformer quartz sand, all through the power administrations acceptance, praised by users.
