Chemical composition of magnetite magnetite filter Fe3O4, crystal is equiaxed oxide minerals, crystals often has octahedron and rhombic dodecahedron, collection of grainy or lumpy. Intact monocrystalline octahedral or rhombic dodecahedron, was when rhombic dodecahedron, parallel stripes of the diamond crystal surface often face long diagonal direction. Compact block or granular aggregates. Color iron black, streak black, semi-metallic luster or metallic luster, opaque, no cleavage, Mohs hardness 5.5-6, specific gravity 4.8-5.3. First, magnetite filter characteristics magnetite filter media filter is a three essential materials. It has a filtering speed, interception capability, long life cycle and so on. Magnetite media, the appearance of spherical, high mechanical strength, non-toxic and hazardous substances, the proportion of 4.5g / cm3, the capacity of 2.95g / cm3 British hardness 5.5-5.6. Magnetite filter pipe big resistance to water distribution systems. In the three-filter usually it anthracite filter media, quartz sand with, is a better ingredients procedures, backwash easily blended, improve the supporting layer and the water system has a good adaptation performance, multi-layer filter essential filter, filtration rate up to the advantages of 30-40 m / when. So magnetite is an important filter media products. Second, the technical indicators magnetite filter (1) magnetite filter test project Technical indicators density / g? Cm ≥ 4.5 clay content /% ≤ 2.5 size range / mm 0.25 ~ 0.5 (three) particle size less than the lower limit of the particle /% ≤ 3 size greater than the upper limit of the particle /% ≤ 2 (2) magnetite project supporting material testing Technical indicators density / g cm ≥ 4.4 clay content:? particle size of less than 2mm /% ≤ 2 particle size greater than 2mm /% ≤ 1 size range / mm 0.5 ~ 1; 1 ~ 2; 2 ~ 4; 4 ~ 8 particle size less than the lower limit of the particle /% ≤ 5 size greater than the upper limit of the particle /% ≤ 5 Third, magnetite media Purpose: Domestic water supply, filtration and purification treatment of industrial water supply, sewage treatment. Fourth, magnetite media packaging and storage of packaging and storage: durable fabric bags, particle size less than o.5mm magnetite media, pull up sleeves should be added to the inner bag, net weight 40kg. Packaging to prevent breakage, avoid leakage or mixed with debris, filter and supporting material should not be stacked together, not stacked with other materials.
