The main sizes of cenospheres in the main applications

1.Cenospheres in the Oilfield industry

Recommend sizes: 300microns  450microns  500microns

Cenospheres offer a unique and powerful solution to one of the oilfield's most persistent challenges: managing pressure in low-strength formations. Their ability to reliably reduce density while maintaining stability and strength makes them a go-to additive for designing advanced drilling fluids and cement slurries, leading to safer, more efficient, and more economical operations.

Cenospheres, with a particle size of 300 microns, 450 microns, 500 microns, play a crucial role in oil well cementing.

Cenospheres contribute to cement's both in low density and improve compressive strength, minimize fluid migration, and enhance thermal insulation. The applications in oil well cementing helps optimize the cement formulation, ensuring reliable and efficient wellbore integrity.

2.Cenospheres in the Paint and Coating industry

Recommend sizes: 100microns  150microns  300microns

As a functional filler, cenospheres are used in paints and coatings (primarily for fire retardant coatings, high temperature resistant coatings, thermal insulation coatings, and intumescent coatings) to significantly reduce the density of the paint, unlike irregularly shaped particles, cenospheres can easily roll over each other. This gives the system using cenospheres lower viscosity and better fluidity. The sprayability of the system is also improved.

The fine sizes 100microns 150microns making it lighter and easier to apply, ensuring better coverage. They also create better adhesion and cohesion in the coating matrix.

3.Cenospheres in the Refractory and Foundry industry

Recommend sizes: 380microns (40mesh) 180microns(80mesh) 40-80mesh and 40-100mesh

Due to their perfect spherical shape, cenospheres act like millions of tiny ball bearings within the refractory mix.This significantly improves flowability and pumpability of castables and gunning mixes. It allows for easier placement, especially in complex shapes and around embedded components, reducing labor and ensuring a more uniform installation.
Cenospheres can withstand the high temperatures of molten metal (iron, steel, aluminum).When used in mold and core washes, they enhance the refractoriness of the mold surface, protecting the sand from being fused by the hot metal and resulting in a cleaner casting surface.

The 40mesh and 80mesh cenospheres have a moderate particle size, with a naturally formed particle size of 1-250 microns and a specific surface area of ​300-360cm²/g. They can be used directly and the fineness can meet the needs of various products.
