Cobblestone as a natural stone, from the tens of millions of years ago, experienced the crustal movement after the uplift produced by the ancient river bed of gravel in the mountains, experiencing the impact of flash floods, water transportation in the process of constant pressure and friction. Tens of thousands of years of vicissitudes in the course of evolution, which suffered waves of water will hit the campaign was lost gravel collision friction irregular edges and corners, and sand was a deep silence of millions of years underground. Cobblestone main chemical composition is silicon dioxide, followed by a small amount of iron oxide and traces of manganese, copper, aluminum, magnesium and other elements and compounds. They themselves have different colors, such as red for iron, copper for blue, purple for manganese, silica gel for the semi-transparent yellow pulp stone, jade green color with minerals and so on; as a result of these ions into dioxide pigment Hydrothermal Si in the type and content, thus showing a bias, changing the color depth, so that the stone showing a black, white, yellow, red, Molv, color, and other Qinghui.
The cobblestone derivatives:
Cobblestone products: natural color of the stone mechanism, the river gravel, stone, dry stone sticky, Penshua stone, landscape stone, petrified wood, rock culture, natural colors, such as Marble meters of construction and interior decoration materials used in high-staining sand , Non-toxic, tasteless, non-decolorization. Hard quality, vivid color, simplicity, with resistance, wear-resistant corrosion-resistant properties of natural stone, is an ideal green building materials.
The cobblestone purposes:
Pebbles are widely used in public buildings, villas, garden construction, laying roads, parks rockery, bonsai-filled materials, garden art and other high-level the superstructure. Both carry forward the ancient oriental culture, in turn, Western classical, elegant, artistic style of getting back to basics.
Pebbles for water purification, sewage treatment, electricity, etc. garden project has provided high-quality materials. Also ceramics, precision casting, paper, abrasion, chemical, silicon, national defense, such as the provision of raw and auxiliary materials.
Material cobblestone physical parameters: 95% of the silicon dioxide (SiO2), as well as other trace elements.
Performance: 98% of the surface finish and strength in more than 600 Kg/M2.
