Currently, it makes microwave radar, infrared, radar or other electromagnetic wave radar and acoustic detection system shield absorbing materials have been widespread concern in the military field. Near infrared reflective material can be used in aviation, aerospace, building materials, vehicles, weapons and other fields.
Cenospheres powder density is small, the metal surface after its treatment, can be substituted for the denser metal electromagnetic wave absorbing powder (RAM) or prepared electromagnetic shielding (EMI) material.

Hollow glass beads, high temperature, corrosion resistance, low creep, good quality of light and chemical stability, excellent mechanical properties and thermal physical properties, get in the building materials, plastics, rubber, paint, and other fields are widely used. Through the hollow glass microspheres surface modification, plated with a layer of metal that can make it conductive or electromagnetic wave absorption performance.

Chemical plating method in the surface of hollow glass microspheres silver plated layer of metal, it is possible to have good conductivity, the conductive rubber can be used as an electromagnetic shielding conductive filler.

The mixture of hollow glass beads:
The hollow glass microballoon filled quantity generally between 5% and 20%. Hollow glass beads are easily mixed with resin, the general advice under the mixing speed of slower in the last stage of the hybrid hollow glass beads. If you must use the high pressure pump, it must be determined in advance the strength of the hollow glass microballoon whether meet the requirements.

Light weight; bulky
Hollow glass microspheres density of about one dozen points of traditional filler particle
density, after filling can greatly reduce the weight of the base product, alternative and
save more resin production, reduce product cost.

Has organically modified (lipophilic) surface
Hollow glass beads wetting and dispersing readily be filled in the most thermosetting
thermoplastic resin, such as polyester, epoxy, polyurethane and the like.

High dispersion, mobility
Since the hollow glass microspheres are tiny balls, the liquid resin than the sheet-like,
acicular or irregular-shaped filler even with good fluidity, so that excellent filling
performance. More importantly, such a small bead is isotropic, it does not produce a
result-oriented in different parts of the shrinkage caused by inconsistent ills, ensure
that the product is dimensionally stable and will not warp.

Insulation, sound insulation, insulation, low water absorption
Internal hollow glass microspheres is rarefied gas, so it has the characteristics of noise,
heat, and is used as a variety of insulation, excellent sound insulation filler products.
Thermal insulation properties of hollow glass microspheres can be used to protect the product
is subjected to alternating between heat and quench emergency conditions caused by thermal
shock. Higher specific resistance, low water absorption so that it can be widely used in
processing the cable insulation.

Low oil absorption
Spherical particles determines the minimum specific surface area and low oil absorption,
use of the process can significantly reduce the amount of resin, even under the premise of
a high added amount of the viscosity is not increased much, greatly improved the production
operating conditions, production efficiency increased by 10% to 20%.

Academy of fine glass beads by using self-developed surface modification agents and complex process, so that the hollow microspheres can be uniformly dispersed in the polymer matrix, microbeads and a substrate with good interfacial bonding, resulting in overall performance high ultrafine hollow microsphere / polymer composite.

It is understood that, with 20% of cenospheres modified PP compared with pure PP, notched impact strength increased by 80% to 100%, tensile modulus, flexural modulus of more than 50 percent, also improved flexural strength only tensile strength remained unchanged or a slight decline. Ultrafine inorganic hollow microsphere belong, wear resistance than polypropylene. In addition, it has a reflex action of ultraviolet, UV can improve performance composites.

Made of Soda Lime Borosilicate Glass , is hollow microsphere which grain size is 10-250microns , wall 2 microns

Specification :

High-performance hollow glass microsphere is a kind of ultra-lightweight inorganic non-metallic material (powder) with

structure(microsphere),and it is a versatile and high-performance new lightweight material developed in recent years .

The new composite (mainstream)materials at twenty-first century . Its true density is 0.20-0.60g/cm3with 2-120um in

diamong features with light weight, large bulky , low thermal conductivity , high compressive strehgth , smoothly mobility etc .

Reflective powder is the high refractive index glass microsphere hemisphere aluminum, provides self-reflection layer, and less to others such as aluminum paste base, so that the beads have a self-reflective function, reflective way more effective than a bottom aluminum paddle method 4-5 times, widely used in reflective paint, reflective ink and screen printing.
High refractive glass microsphere having predominantly retroreflective properties. The so-called return reflection is an optical phenomenon, when the light shines on an object like a lens, focusing refracted, and then they return light refracted through the lens focus from reflection direction.After the products using high refractive index glass beads and a half after the surface of aluminum as the reflector, with a strong reverse retro-reflective properties, making 85% of the light directly reflected back toward the source.Reflective retroreflective brightness caused by the driver and the night allows workers with a light source in case of poor vision at night or circumstances clearly see pedestrians and obstacles to the goal, to ensure that both safety.

Hollow glass beads is a small density, glass microspheres lightweight, high strength. The main ingredient is Sio2 and Al2o3, because of its unique chemical properties, physical properties, and hollow spherical, compared with ordinary glass beads, light weight, low density, good heat insulation performance characteristics, is thermal insulation coatings the main raw material. Because of its smaller particle size, equal to or greater than the ordinary paint fineness of the filler, which can be added directly to the filler coating systems, the coating having a cured coating film formed by thermal insulation properties.

Hollow glass beads grout
Hollow glass beads slurry mainly cement, hollow glass microspheres, reinforcing and supporting the additive composition, according to cementing needs, choose a different additive system, the design of different density slurry formulations.
In addition to the strength of the grout and cement and cement formulations label the outside, depending on the size of the water-cement ratio of cement. Select the appropriate water-cement ratio, it can be grout with good flow properties, while other properties are easy to adjust. Whether water-cement ratio is too large or too small, for slurry properties are unfavorable. Too large, floating glass beads, Strength grout; too small, poor water slurry rheological properties, not easy to pumping operations.
Hollow glass beads formulated low-density slurry, poured into the conservation atmospheric consistometer 20min at 45 ℃ condition, and then six-speed rotational viscometer rheological properties, it can be seen, hollow glass beads grout good rheological properties, rheology power-law model in line, show the grout can form a stable royal space structure, to ensure the stability of slurry.
Hollow glass beads low density, high compressive strength, good compatibility with cement additive performance, which can effectively reduce the slurry density; hollow glass slurry system performance and stability, good rheological properties meet the coalbed methane wells cementing security; hollow glass beads slurry filtration system is small, coal-bed methane wells can play a good protection.

Hollow glass microspheres in the application of the cementing cement

Pure cement generally be used on most traditional drilling, but in exceptional circumstances regulate cement density is the key to successful completion and long-term isolation.
There are several methods of adjusting the slurry density has been used. These methods can be used alone or integrated use.
