L Long or Long licensing Anthracite Anthracite filter water purifier is a professional manufacturer, mainly produces anthracite filter media, anthracite filter selection, treatment with anthracite, anthracite filter media, anthracite filtration water purification materials. L Long anthracite filter will not be used alone, in general, and other water purification materials, such as quartz sand used in conjunction. Currently, China is currently using anthracite filter and widely used as a filter. Anthracite commonly known as "white coal", is the deepest coal rank coal. Is a water filtration materials industry. I produced anthracite filter (Standard: People's Republic of China urban construction industry standards (CJ / T43-2005) is the choice and quality of Shanxi Jincheng Anthracite Mining Jiaozuo two as raw material crushing, screening, washing and processing. . to Anthracite filter characteristics are: high fixed carbon content, density, high strength, good appearance gloss, chemical stability, and has good ability to maintain solid particles, suspended particles can reliably improve the removal of anthracite filter does. containing toxic and hazardous substances, in acidic, neutral water, not dissolved. Anthracite compression wear resistance, there is enough surface area and particle size gradation reasonable due anthracite filter has a better ability to maintain solid particles therefore suspended particles can be reliably improved scavenging anthracite filter suitable for drinking water and industrial water filtration or Long Anthracite technical requirements: 1, anthracite filter crushing rate and wear rate should not exceed the sum of 3% (percentage by mass, the same below). 2, the average density of anthracite filter is generally not less than 1.4g / cm3, not more than 1.6g / cm3. 3, anthracite filter media should be free of visible dirt, shale and foreign debris. anthracite clay content should not exceed 3%, greater than the density of the material content of 1.8g / cm3 should not exceed 8%. 4, anthracite filter media * soluble rate should not exceed 3.5%. SHENGLONG anthracite filter media particle size: one size range for anthracite filter for drinking water: 0.8-1.2mm, 1.2-2mm; industrial water Anthracite particle size ranges: 1-2mm, 2-4mm, 4- . 6mm 2, in a variety of particle size in the range of anthracite, particle size less than the specified limit should not exceed 3%, greater than the prescribed maximum particle size should not exceed 2% or Long Anthracite technical indicators: data analysis project analysis data analysis project analysis of soluble carbon content% ≥90 * proportion rate% ≤3.5 g / cm 1.4-1.6 density wear rate% ≤1.3 g / cm 0.95 Broken rate% ≤1.5% ≤2 porosity, clay content% 43 liters Long Anthracite Packaging and storage: plastic woven bag packaging when anthracite filter Gongyi City or Long Water Material Co., Ltd.
