cenosphere的意思|示意

'

The word 'cenosphere' is derived from two Greek words, 'kainos' and 'sphaira', meaning “new” and “sphere” respectively. It refers to a type of lightweight material made up of mostly hollow particles, consisting of micro-size glass-like beads of various size and color. It is a type of manufactured microspheres derived from the burning of coal in power plants, and is composed mostly of silicon dioxide (SiO2), alumina (Al2O3) and iron oxide (Fe2O3).

Cenospheres have many uses due to their low density and lightweight properties, including waterproofing and fireproofing products, coatings, insulation materials, fillers, additive materials, paint and plastics, and other construction materials. Furthermore, they are great for lightening the weight of concrete, gypsum and mortar. They are also often used in water filtration systems and as adsorbents.

Cenospheres are available in a variety of sizes and colors, ranging from 1 to 1000 microns. The smaller particles can be used as a reinforcing agent in elastomeric coatings and polymers, while larger particles are suitable for use in heavy-duty coatings, liners and insulation materials.

In conclusion, cenospheres are a versatile, lightweight material with a variety of applications, such as waterproofing and fireproofing products, coatings, insulation materials, fillers, additive materials, paint and plastics, and other construction materials. They are available in a wide range of sizes and colors, from 1 to 1000 microns.
