Cenosphere/Fly ash cenosphere/Floating Beads/Ceramic Hollow Ball
The chemical composition of floating beads is mainly silicon dioxide and aluminum oxide. It has many characteristics such as fine particles, hollow, light weight, high strength, wear resistance, high temperature resistance, thermal insulation and flame retardant. It is widely used in One of the raw materials for the refractory industry.
function of Cenosphere powder :
Low Density: Density ranging from 0.50 g/cm3 to 0.80 g/cm3. Compared to most ground minerals and other resins,Cenospheres are 30-85% lighter.
Low resin demand/High loading potential: spheres have the lowest surface area to volume achievable with their spherical shape,cenospheres produce less viscosity.
High Compressive Strength: Cenospheres can greatly improve the weariness properties of the
end products.
Low Shrinkage: Cenospheres are one of the few products in the filler industry today that can meet the the requirements for low shrinkage.
Low Thermal,Electrical and sound Conductivity: Cenospheres are extremely resistant to heat and typically have a melting point in excess of 13000c. As cenospheres are hollow they have a relatively low co-efficient of thermal conductivity,typically 0.09w/mu
Inertness: Cenospheres can be utilized in solvents,organic chemicals water,acids and alkalies while maintaining their integrity.
Thermal stability: As cenospheres are formed in the boilers ,they are thermally stable in temperature exceeding 10000C
Insulation: Cenospheres can be used in electric filling and sealing materials ,instruments boards,
switches etc.
Cost effectiveness :Cenospheres are 50~200% less expensive than man made hollow glass speheres,in comparison to less expensive fillers.
