Cenosphere：light weight and high strength, a diversified choice for industrial application

Cenosphere are a kind of light nonmetallic mineral particles extracted from fly ash in thermal power plants. They are hollow, closed-celled, light, heat-insulating, high-temperature resistant and corrosion resistant, and have a wide range of applications.

In the industrial field, it is a high-quality refractory material, which can be made into lightweight refractory bricks and fire-retardant coatings to improve heat insulation performance and reduce energy consumption; In the petroleum industry, it is used for cementing and plugging, reducing the specific gravity of mud, or as a pipeline insulation material to adapt to the high temperature oil well environment. In the construction industry, Cenosphere are efficient thermal insulation materials, which can be used to prepare thermal insulation coatings and thermal insulation mortar for external walls or roof thermal insulation projects.

In terms of material modification, cenosphere can be used as light fillers of plastics and rubber to replace part of resin, which can reduce the cost and improve the strength and high temperature resistance of materials. In the foundry industry, it is used to make thermal insulation risers to reduce the shrinkage defects of castings. In addition, its insulation is suitable for high-voltage cables and electronic packaging materials, and the hollow structure can also be used for the preparation of sound-absorbing materials.

With the characteristics of light weight and high strength, the cenosphere are also involved in the fields of aerospace composite materials and deep-sea exploration buoyancy materials, helping to reduce the weight and improve the performance of equipment. Its resource utilization has both environmental protection value and economic benefits, and it has become a typical representative of high-value application of industrial solid waste.
