Many people hear or see just a “cenosphere” is the word, is not very familiar with, there are a lot of people do not understand this, you do not even have heard of the “cenosphere” There is a lot of misunderstanding, in order to make the majority of customer base to more clearly understand the “cenosphere,” the word for everyone on our “cenosphere” in a deep knowledge summary. The following is the “cenosphere,” the relevant product knowledge.
I. The cenosphere overview:
A cenosphere can float on the surface of the fly ash hollow ball, pale, thin-walled hollow, light weight, bulk density 250-720kg / m3, particle size of about 0.1 mm, surface sealing and smooth, small thermal conductivity, refractoriness ≥1700 ℃, is an excellent refractory insulation, widely used in oil drilling and production aspects of lightweight castable.
The chemical composition of cenosphere of silica and alumina-based, with fine particles, hollow, light weight, high strength, wear resistance, high temperature, thermal insulation, fire-retardant insulation and other functions, is now widely used various industries.
Cenosphere most sold specifications: 20 mesh, 30 mesh, 40 mesh, 50 mesh, 60 mesh, 80 mesh, 100 mesh, 150 mesh, 200 mesh, we can also be processed according to customer requirements.
II.The cenosphere features:
1.High refractoriness: cenosphere with high refractoriness, generally up to 1600-1700 degrees celsius, making it an excellent high performance refractories.
2.Light weight, thermal insulation: cenosphere thin-walled hollow, not only lightweight, but also excellent thermal insulation, which play an active role in its field of lightweight thermal insulation material foundation.
3.High hardness, high strength: because hard vitreous silica-alumina oxide minerals are cenosphere phase formation, Ta Mok’s hardness 6-7, the true density of 2.10-2.20 g / cm3, therefore, has a high cenosphere strength.
4.Fine grain size, surface area: size cenosphere natural form 1 to 250 microns. The specific surface area 300-360g / cm2, and cement almost. Thus, the floating bead without grinding, can be used directly. Fineness can meet the needs of a variety of products.

III.The cenosphere purposes:
1.Fire-resistant insulation materials: sintered refractory bricks such as light, light unburned bricks, pipe insulation shell, fireproof insulation coatings, lightweight insulation wear-resistant glass and steel.
2.Building materials: steel fiber and cenosphere with the same purpose, can be used as a construction material.
3.The oil industry: oil well cementing, anti-corrosion pipe insulation, undersea oil fields, flotation devices, oil well drilling muds reducing agent, oil and gas pipelines and other aspects.
4.Insulation material: plastic activation fillers, insulators and other high temperature and pressure.
5.The paint industry: paint, ink, adhesives, insulating paint, anti-corrosion paint, high temperature fire retardant paint, insulation coatings, floor paint, putty and other cars;
6.Aerospace and space development: satellites, rockets and other surface composite materials, marine equipment, ships, submarines, and other deep-sea;
7.The plastics industry: such as automobile accessories, appliance housings, fans, speakers, castings, gears, structural parts, zippers, tubes, plates and so on.
8.FRP products: a variety of glass products, artificial marble, glass and steel ships, crafts, etc;
9. Packaging materials: transformer potting materials, electronic packaging materials.
