Natural pebbles variety of water plants dedicated

Cobblestone products are: Advanced stained sand natural color mechanism pebble, river gravel, stone, dry Nien, stencilled stone, landscaping stone, petrified wood, culture stone, natural color marble rice and other decorative building materials and interior decorative non-toxic, tasteless, non-marking. Quality of hard, sharp color quaint, with compression, wear resistant properties of natural stone, is an ideal green building materials. As a natural pebble stone, from experienced crustal movement of millions of years ago after the old riverbed gravel mountain uplift produced, experiencing the impact of flash floods, water removal process of continuous extrusion, friction. Tens of thousands of years of tremendous evolution, they tormented waves flush the movement, the collision was gravel friction lost irregular edges, and sediment has been buried in an underground silence of millions of years. Cobblestone main chemical composition is silicon dioxide, followed by a small amount of iron oxide and small amounts of manganese, copper, aluminum, magnesium and other elements and compounds. They themselves have different colors, such as crimson by iron, blue by copper, manganese violet person, colloidal silica stone translucent yellow marrow, emerald color with green mineral and so on; since these ions into dioxide pigment Silicon hydrothermal type and content of different, thus showing shades, ever-changing shades of color, the pebbles showing black, white, yellow, red, dark green, and other colors pebbles schungite uses: cobblestone are widely used public buildings, villas, garden buildings, paved roads, parks rockery, bonsai filling materials, garden art and other senior superstructure. Carry forward the ancient oriental culture, but also reflects the Western classical, elegant, artistic style of getting back to basics. Pebbles also water, sewage treatment, electricity, garden items of projects to provide high-quality materials. Also ceramics, precision casting, paper, sprayed grinding, chemicals, silicon, national defense, such as raw and auxiliary materials. Pebbles, gravel supporting layer filter water purification process is indispensable supporting materials, natural pebbles, spherical high mechanical strength, moderate density, chemical stability, non-mica, shale and other impurities, white and variegated points two kinds. Cobblestone supporting layer media, points (natural) pebbles and (machining) Two quartz gravel. Natural pebbles is the result of natural river excavation. Water. Screening from, and the surface is smooth, nearly spherical shape, quartz gravel is selected using the quartz ore processing, chemical stability, high mechanical strength, a water filtration process The following media must support layer, common specifications: 2-4mm.4-8mm.8-16mm.16-32mm.32-50mm. Gravel (gravel) filter gravel (gravel) filter, commonly known as the supporting layer filter or filter, points (natural) pebbles and (machining) two cushion quartz gravel. Natural pebbles is the result of natural river dredging, washing, screening made nearly spherical, and smooth surface. Quartz ore crushing gravel finishing. Widely used in water treatment supporting layer of water, mechanical filter, anion and cation exchange.
