Get the Best Fly Ashes from Cenosphere Exporter

Cenospheres are inert hollow silicate spheres. They are largely used to reduce the weight of Plastics, Rubbers, Resins, cement etc. used widely as stuffing lubricants in oil drilling operations under high heat and high-stress conditions down the hole. Also used as oil well cementing, mud putty and other related applications. Cenosphere exporters use it for an extended plastic compounds, as they are well-suited with plastisols thermoplastics, Latex, Epoxies, Phenolic resins, Polyesters, and urethanes. The compatibility of Cenospheres with special cement and adhesives coating and composites have been well recognized. Cenosphere is broadly used in a range of products, including sports equipment, automobile bodies, insulations, paints and fire, marine craft bodies, and heat protection devices.

Cenosphere exporter exports the cenosphere having chemical properties as:
  • Silica: 50-60%
  • Aluminum: 33-39%
  • Iron Oxide: 1.3-5%
  • Calcium: 0.5-1.5%
  • CO2 Gas: 70%
  • Manganese: 0.8-1.5%
  • Nitrogen Gas: 30%
What is the type cenosphere exporter use to export?

 Fly Ash: It is one of the residues generated in the combustion of coal. Fly ash is generally taken from the chimneys of power generation, where the bottom ash is removed from the foot of the furnace. Before, fly ash was usually released into the atmosphere with the smoke stack, but today pollution control equipment has mandated to capture the ashes earlier to release. Conditional upon the source and character of the coal being burned, the mechanisms of the fly ash produced vary significantly, but all fly ash includes generous amounts of silica (silicon dioxide, SiO2) (both amorphous and crystalline) and lime (calcium oxide, CaO).

ASTM 618F: Fly ash is defined into two classes by ASTM C618- Class F fly ash, and Class C fly ash. Both the classes differentiate each other on the basis of the amount of silica, calcium, iron, and alumina present in the ash. Thus, the chemical properties of the fly ash are generally influenced by the chemical contamination in the coal burned.

The burning of harder, older anthracite and bituminous coal typically produces Class F fly ash, whereas Class C fly ash is produced from the burning of younger lignite or sub bituminous coal, in addition to having pozzolanic properties, also has some self-cementing properties.
