Henan quartz sand filter manufacturer classification and application areas

Quartz sand classification and application areas quartz sand is made from natural quartz ore, by crushing, washing, screening, pickling, drying, secondary screening made of a water filter; common quartz sand There are two, one is ordinary quartz sand, the other is a refined pickling sand. Quartz sand: a big hardness, good corrosion resistance, high density, high mechanical strength, long lines carrying sewage capacity cycle characteristics, it is an ideal material for chemical water treatment. The appearance of a diamond shape, spherical, pure white, high mechanical strength, interception capability, good acid resistance and other characteristics. Play the role of quartz sand filter, like water infiltration into the ground through the gravel, like those suspended solids in the water block down, mainly for those fine suspended solids. Quartz sand as filter material applications, quartz sand is combined with the filter container for trapping suspended solids in water colloidal particles of impurities, which play a filtering effect. Can be divided into the following categories: 1. Ordinary quartz sand: mainly used in sewage treatment, three to five years with no problem, as long as the quartz sand to prevent the loss of the line, is contaminated does not matter, because the sewage treatment sludge It can be aerobic or anaerobic respiration, the degradation of pollutants in sewage. 2. Refining quartz sand: used in water treatment, the sand filter, generally two to three years to be replaced, usually after being contaminated, contaminants wrap quartz sand filter can no longer play a good role in the It can only be replaced. Quartz sand through Iso9001-2000 quality system certification. Are stable in neutral and acidic water in the range of values, but there is little dissolved in alkaline water, chemical water treatment SiO2 increments of not more than 2mg / L. Common Specifications: 0.5-1.0mm 0.6-1.2mm 0.8-1.6mm 1.0-2.0mm 2.0-4.0mm 4.0-8.0mm 8.0-16mm 16-32m refined quartz sand physical and chemical analysis: Data analysis project identification project identification data Analysis of project identification data density SiO2 content of 99.5% 1.75t / m3 hydrochloric acid soluble rate of 0.4% 7 Mohs hardness of the wear rate of 0.3% acid resistant to acid boiling point 2550 ℃ crushing rate of 0.35% alkali alkali resistance good ash melting point 1750 ℃ flour yield 0.25% Zn content of 2.65 specific gravity of 0.005% porosity 43% quartz sand packaging and storage: quartz sand is woven bag, weight 50KG, 25KG or tons of bags. Quartz sand should not be stacked with supporting materials and other media. Quartz sand and other media should not be stacked with other hazardous materials polluting goods. Can not be missed days storage, dust pollution prevention storage, general warranty period of ten years. Quartz sand filter criteria: quartz sand Construction ministerial standards: natural quartz deposit as raw materials, mining, crushing, washing, screening and other processing (high-purity quartz sand pickling), high mechanical strength, chemical stable performance in line with the Ministry of Construction (CJ / T43-1999) standard.
