Pebbles and natural pebble, HeLuanShi pebbles, as a kind of natural stone material, from experienced million years ago after the crust movement produced by ancient riverbed uplift freestone mountains, experiencing flash floods impact, water handling continuous extrusion, friction. In the tens of thousands of years vicissitudes of life evolution process, they drew water blunt weather-beaten wave motion, be gravel collision friction lost irregular edges, and sediment a were buried deep underground silent millions of years. Pebbles main chemical compositions is sio2, followed by a small amount of ferric oxide and trace of manganese, copper, aluminum, magnesium and elements and compounds. They itself has different pigment, such as iron, blue for the latosolic red person for copper, purple, yellow translucent person for manganese silica gel for stone pulp, emerald green containing green minerals, etc. Because these pigment ions into the silica hydrothermal varieties and contents of different, thus showing shade, depth of ever-changing colour, the pebbles show black, white, yellow, red, blackish green, walked etc lubricious department. Pebbles products are: natural colors, the mechanism of HeLuanShi, extend pebbles, dry spray brush sticky stone, stone, and made JingShi, petrified wood, culture stone, natural color lidan meters and other building decoration materials and interior decoration with advanced dyeing sand, non-toxic, tasteless, nondiscolouring. Quality hard, bright and lustrous is simple and unsophisticated, with compressive, wear-resisting corrosion resistant properties of natural stone, it is a kind of ideal green building materials. The purpose: pebbles are widely used in public building, villa, courtyard architecture, paved roads, park rockery, miniascape filling materials, garden art and other senior superstructure. It is disseminating ancient Oriental culture, and embodies the western classical, elegant, piao guizhen art style. Pebble for water, sewage treatment, electric power, gardens and so on a project to provide the high quality material. Also for ceramics, precision casting, papermaking, spray grinding, chemical, monocrystalline silicon, national defense and provide raw and auxiliary materials.
