Product Description
Our company has been
engaged in the refractory materials industry for many years,
focusing on the in-depth research, development, production, sales,
and service of refractory materials. Currently, we have established
a complete set of management models, production, and quality
control systems. In recent years, with the rapid development of the
refractory materials industry, the demand for quality and variety
has been continuously increasing.
Cenospheres are
grayish-white spherical in appearance and possess multiple
properties such as fine particles, light weight, high strength,
wear resistance, low thermal conductivity, high refractoriness,
thermal insulation, electrical insulation, and uniform stress and
strain. They are widely used as reinforcing fillers in fields such
as refractory and thermal insulation materials, plastics, coatings,
foundry, ceramics, and petroleum drilling. They can not only
effectively improve product performance or construction results but
also significantly reduce production costs.

III. Characteristics of
Cenospheres:
1.High refractoriness:The main chemical
components of cenospheres are oxides of silicon and aluminum. Since
the melting point of silicon dioxide is as high as ***5 degrees
Celsius, and the melting point of aluminum trioxide is ***0 degrees
Celsius, both are high refractory substances. Therefore,
cenospheres have extremely high refractoriness.
2.Lightweight, thermal
insulation: Cenospheres have thin walls and hollow
interiors, with a semi-vacuum inside the cavity, resulting in
extremely slow and minimal heat conduction. They are not only
lightweight but also have excellent thermal insulation
properties.
3.High hardness and
strength: Because
cenospheres are hard glass bodies formed by silicon-aluminum oxide
mineral phases (quartz and mullite), their hardness can reach Mohs
**7, and their static pressure strength is as high as *****0MPa,
thus having high strength.
4.Insulating and
non-conductive: The
resistance of general insulators decreases with the increase of
temperature, but high-strength cenospheres are the opposite, with
resistance increasing as temperature rises. This advantage is not
possessed by other insulating materials. Therefore, it can be made
into insulating materials with excellent
performance.
5.Fine particle size and large specific
surface area:The naturally formed particle size of high-strength
cenospheres is *****5 microns. The specific surface area is ******0
g/cm², which
is equivalent to that of cement. It can be used directly without
grinding. The fineness can meet the needs of various
products.
IV. Uses of Cenospheres:
1.Refractory and thermal insulation
materials: Such as
lightweight sintered refractory bricks, lightweight non-fired
refractory bricks, casting insulation risers, pipeline insulation
shells, fireproof and thermal insulation coatings, thermal
insulation pastes, composite thermal insulation dry powders,
lightweight thermal insulation and wear-resistant glass fiber
reinforced plastics.
2.Building
materials: Building
decoration, high-grade pavement materials, roof waterproof and
thermal insulation coatings, modified asphalt,
etc.
3.Petroleum
industry: Oilfield
cementing, pipeline anti-corrosion and insulation, offshore
oilfields, floating devices, oil well drilling mud lightening
agents, oil and gas transmission pipelines, etc.
4.Insulating materials; Plastic activated
fillers, high-temperature and high-pressure insulators,
etc.
5.Coating
industry: Paints,
inks, adhesives, stealth coatings, insulating paints,
anti-corrosion paints, floor paints, high-temperature resistant and
fireproof paints, interior and exterior wall coatings, thermal
insulation coatings, floor paints, automotive putties, atomic ash,
etc.
6.Plastic
industry: Such as
automotive trim parts, instrument panels, home appliance casings,
fans, speakers, lamp assemblies, plates, etc.
7.Glass fiber reinforced plastic products:
Various glass fiber reinforced plastic products, artificial marble,
glass fiber reinforced plastic ships, handicrafts,
etc.
8.Encapsulation materials: Transformer
potting materials, electronic encapsulation materials,
etc.
