Reflective additive for paint
In recent years, a new type of material has been developed, which is hollow glass beads with both light weight, low thermal conductivity and high strength.
Hollow glass beads in reducing the weight of products and thermal insulation effect is obvious, is widely used in the manufacture of composite materials, such as fiberglass reinforced plastic, artificial marble, artificial agate and so on.
More unexpectedly, hollow glass beads can also play a unique anti-cracking properties in the process of product reprocessing, and can even be used in aviation, aerospace, navigation and other fields.

Reflective additive for paint
1) Application in the field of composite materials
Composite materials field on the strength of the product, dimensional stability, insulation and other high performance requirements, and hollow glass beads can just meet the performance requirements in this regard.
As an example, hollow glass beads of low density, high strength, good insulation, when used in place of epoxy resin synthetic foam blocks, people are surprised to find that it can significantly increase the strength of synthetic foam blocks, bending load up to 2500kg, is the strength of ordinary engineering plastics 3 times.
Not only that, hollow glass beads also improve the dimensional stability of synthetic foam blocks at high temperatures. In addition to synthetic foam blocks, in the repair of resin putty, the manufacture of lightweight core material, spraying glass fiber reinforced plastic, pultrusion process and other composite materials in the field, but also common hollow glass beads.
(2) Applied in the field of oil well cement
With the continuous exploitation of mankind, resulting in deepening the depth of oil wells, the more severe geological conditions, the urgent need for low density, high strength and non-absorbent raw materials as a mitigating agent, to make low-density oil well cement.
Hollow glass beads have been awarded international patents in the production of low-density cement, and when extended to the field of oil well cement, hollow glass beads have unsurprisingly played an irreplaceable advantage, and can be used to synthesize and produce solid cement slurries and drilling fluids.
As a new type of cementing slurry mitigation material, hollow glass beads can be used to formulate solid cement slurry with compressive strength up to 82MPa and density between 0.80 and 1.50 g/cm3, which can reduce cementing cost while improving the fluidity of cementing slurry, and enhance the construction efficiency and quality.
As a mitigating agent, hollow glass beads can also be used to make drilling fluid. In practical application, it is found that hollow glass beads can seal the liquid to avoid contamination of the coal seam, and the chemically stable hollow glass beads can also tolerate alkaline drilling fluid slurry, with stable performance, which can significantly improve the drilling yield.
3) Application in the field of solid buoyancy materials
We all know that when diving, the deeper the depth of the signature, the greater the pressure received by the human body, the same is true for solid buoyancy materials.
Hollow glass beads can be used to synthesize and produce high-strength, low-density solid buoyancy materials by enhancing the dispersed stress and load bearing of the composite material to enhance the strength of the composite material, which is capable of performing the task of underwater deep-diving at the level of 1,000 meters.
4) Application in the field of coatings
Paint is usually applied to the surface of automobiles, ships or brick walls, which are exposed to outdoor environments for a long time and corroded by direct sunlight and rain.
In order to save the maintenance cost of the paint, it is necessary to make the paint at the same time with waterproof, anti-fouling, anti-corrosion, high temperature resistance and other properties. The thermal conductivity of hollow glass beads is between 0.03 and 0.07 W/(m-K), which is both waterproof, corrosion-resistant and weather-resistant, making it an excellent water-based thermal insulation coating.
Different specifications of hollow glass beads also has flame retardant, noise reduction and other characteristics, can be combined with different application needs to synthesize high-performance coatings to meet the requirements.
