Hollow Fly Ash Cenosphere for Casting/Construction/ Oil Well Cementing

Hollow Fly Ash Cenosphere for Casting/Construction/ Oil Well Cementing

Product Description:

Cenosphere, sometimes called microsphere, is a lightweight, inert, hollow sphere made largely of silica and alumina and filled with air or inert gas., typically produced as a byproduct of coal combustion at thermal power plants. The color varies from gray to almost white and their density is about 0.6-0.9 g/cm³, all these properties give it a wide application for insulation, refractory, oil drilling, coating, and construction use.

Cenosphere Specification:

SiO2 50-55%

Al2O3 28-33%

Fe2O3 2-4%

SO2 0.1-0,2%

CaO 0.2-0.4%

MgO 0.8-1,2%

Na2O 0.3-0.9%

K2O 0.5-1.1%

Product Applications:

1), Chemicals/Coating/Painting — Provide measuring tool in biology and drug research, besides added to paints

and epoxies to modify viscosity and buoyancy ;

2), Plastics — Used to decrease material density (glass and polymer);

3), Ceramics — Used to create porous ceramics used for filters;

4), Cosmetics — Used to hide wrinkles and give color;

5), Electronic paper — Dual Functional microspheres used in Gyricon electronic paper

6), Insulation — expandable polymer microspheres are used for thermal insulation and sound dampening.

7), Retroreflective — added on top of paint used on roads and signs to increase night visibility of the road stripes and signs;
