Common quartz sand

Common quartz sand is a kind of water treatment filter, which is composed of natural quartz ore by crushing, washing, drying, and drying two times. SiO2 > 90 - 99%Fe2O3 less than 0.06 - 0.02%, refractoriness of 1700 degrees, large particles in appearance, and yellow skin Capsule on the surface. The filter material has the characteristics of no impurity, no calibration angle, high density, high mechanical strength, long loading capacity and long service life, and is an ideal material for chemical water treatment.
Ordinary quartz sand filters play the role of filtering, just as water permeates the sand into the ground, blocking the suspended objects in the water, mainly for the fine suspended matter. Quartz sand technology has reached the leading level in China.
The application of ordinary quartz sand as filter material: quartz sand is combined with filter container, which is used to intercept particles of suspended particles in water, and thus play the role of filtering.
If it is used in sewage treatment, ordinary quartz sand is generally used in 35 years, so long as the quartz sand is prevented from the loss of quartz sand, it is not tight, because in the sewage treatment, the sludge can be aerobic or anaerobic respiration to degrade the pollutants in the sewage.
If it is used in pure water treatment, most of the refined quartz sand, in the sand filter, generally 2 to 3 years to change, usually contaminated, pollutants wrapped in quartz sand can not be a good filtering effect, can only be replaced.
The unique physical and chemical properties of common quartz sand make it play an important role in the aviation, space, electronics, machinery and the rapid development of IT industry, especially its internal molecular chain structure, crystal shape and lattice change law, so that its high temperature resistance and thermal expansion coefficient are small and high. Insulation, corrosion resistance, piezoelectric effect, resonance effect and its unique optical characteristics play an increasingly important role in many high-tech products.
Common quartz sand is an important industrial mineral raw material, non chemical dangerous products, widely used in glass, casting, ceramics and refractory materials, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical, plastic, rubber, abrasive and other industries. It can be transported, transported by train, and transported by water. Industrial production is generally 50KG or 25KG packaging and export ton bag packaging. Common specifications: 0.5-1.0mm 0.6-1.2mm 1-2mm 2-4mm 4-8mm 8-16mm 16-32mm. (mm for millimeter units)
