               Cenosphere

Product introduce:

Made up of silica, iron and alumina, cenospheres have a size range from 1 to 500 microns with an average compressive strength of 3000+ psi. Colors range from white to dark gray. They are also referred to as microspheres, hollow spheres, hollow ceramic microspheres, micro-balloons, or glass beads....

Cenosphere is able to float on the surface of fly ash hollow ball, pale, thin-walled hollow, very light weight, bulk density 720kg/m3 (heavy), 418.8kg/m3 (light), particle size of about 0.1 mm , closed and smooth surface, thermal conductivity is small, refractoriness ≥ 1610 °C, is an excellent insulating refractory castable used in the production and light oil drilling areas. The chemical composition of floating beads of silica and alumina-based, with fine particles, hollow, light weight, high strength, wear resistance, high temperature, heat insulation, fire-retardant insulation and other functions, now widely used in One of refractory materials.

 

Applications:

Cenosphere applications offer many benefits over mined materials,primarily cost and weight reduction. Of their many uses, microspheresare used as light weight aggregate in oil well cements, sound proofing,thermal insulation, interior and exterior paints, injection molding ofplastics,automotive brake linings, and are even used by NASA in the nose of the Space Shuttle.
Desirable properties include: controllable density for buoyancy, improved flow, excellent thermal insulation, light weight, and high strength. Environmentally friendly and 100% they aid not only the coal fired power plants control their pollution, but make their use earth conscious...

Advantages:

(1) Reduced Raw Materials Cost
(2) Improved Flowability
(3) Reduced Resin Demand
(4) Improved Insulation Values
(5) Reduced End Product Weight
(6) Resistant to Resin Absorption
