● Smooth and rounded appearance: Long-term water flow scouring and mutual collision make the surface of pebbles very smooth without sharp edges and corners.
● Rich and diverse colors: The main chemical component is silica, with small amounts of elements and compounds such as iron oxide, manganese, copper, aluminum, and magnesium. Differences in the types and contents of these pigment ions dissolved in silica hydrothermal fluid give pebbles various colors including black, white, yellow, red, dark green, and blue-gray.
● Hard and wear-resistant texture: Composed of hard minerals, it has the characteristics of compression resistance, wear resistance, and corrosion resistance, with hard quality and long service life⊃1;.
● Often used for floor and wall decoration in public buildings, villas, courtyard buildings, such as laying pebble floors and wall tiles.
● Also used in landscape creation such as park rockeries and garden art to create a natural and primitive atmosphere.
● Concrete aggregate: Pebbles have high strength, low water absorption, and good wear resistance, making them ideal aggregates for concrete. Adding pebbles can improve the strength and durability of concrete, which is widely used in construction structures, bridges, roads and other projects.
● Artificial stone: After crushing, screening and processing, pebbles can be used to manufacture artificial stone, such as artificial marble and artificial quartz stone. These artificial stones have the characteristics of beauty, durability and easy processing, and can be used in interior decoration, countertop production and other fields.
● Abrasive material: Pebbles have high hardness and can be used as abrasive materials for grinding and polishing the surface of various objects. For example, in glass, ceramics, metal and other industries, pebbles can be used in grinding equipment to perform rough grinding and fine grinding on workpieces to improve surface finish.
● Chemical packing: In some chemical reactors and towers, pebbles can be used as packing. It can increase the gas-liquid contact area, improve mass transfer and heat transfer efficiency, and promote chemical reactions. At the same time, pebbles also have corrosion resistance and high temperature resistance, and can work stably in harsh chemical environments.
● Sewage treatment: In the biological filters of sewage treatment plants, pebbles are used as filter media. When sewage passes through the pebble layer, suspended solids, organic matter, microorganisms, etc. in it will be trapped on the surface and pores of pebbles, thereby realizing the purification of sewage. In addition, pebbles can also provide attachment sites for microorganisms to grow, helping to improve sewage treatment efficiency.
● Rainwater collection and infiltration: In urban rainwater management systems, pebbles can be used to construct facilities such as rain gardens and infiltration ponds. They can slow down the speed of rainwater runoff, increase the amount of rainwater infiltration, reduce urban waterlogging, and at the same time perform preliminary filtration and purification of rainwater.
● Silicon raw material: The main component of pebbles is silica. Through a series of processing treatments, high-purity silicon can be extracted, which is used to manufacture electronic components such as semiconductor chips and solar cells. Silicon is an indispensable important material in the electronic industry. With the continuous development of electronic technology, the demand for high-purity silicon is increasing day by day.
● Electronic equipment heat dissipation: Due to the good thermal conductivity of pebbles, in the heat dissipation systems of some electronic equipment, pebbles or heat dissipation materials containing pebbles are used to help dissipate the heat generated during the operation of the equipment and ensure the stable operation of the equipment.
