The application of glass beads in the aerospace industry is mainly reflected in a number of aspects, which can be summarized as follows:

I. Sandblasting cleanup

Military use: In the military field, glass beads can be used as cleanup sandblasting, especially when cleaning precision parts such as aircraft engine turbines, blades, shafts, etc., glass beads, by virtue of their unique physical properties, are able to effectively remove dirt and impurities while reducing the damage to the parts.

II.Making Coatings

 Improvement of reflectivity and durability: In the aerospace field, glass beads (although mentioned here, considering the similarity between glass beads and glass beads in some applications and the fact that glass beads are more widely used in aerospace) are widely used to make aircraft coatings. The addition of glass beads to these coatings significantly improves the reflectivity and durability of the coatings, thereby increasing the visibility of the aircraft at night or under low light conditions and protecting the surface of the aircraft from environmental erosion.

III. Thermal insulation and heat preservation materials

Lightweight and efficient: Hollow glass beads are used to make lightweight and efficient thermal insulation and heat preservation materials due to their low density and low thermal conductivity. The application of these materials in the field of aerospace helps to reduce the weight of the aircraft, while improving the thermal protection performance of the aircraft.

IV. Composite material enhancement

Improvement of performance: Hollow glass beads can also be used as reinforcing fillers for composites, by improving the stacking performance of composites and reducing voids, making composites more dense and homogeneous, thus improving their overall performance. The application of this material in the aerospace field helps to improve the structural strength and durability of the aircraft.

V. Other applications

Microwave dielectric materials: the hollow structure of hollow glass beads gives them a low dielectric constant and loss angle tangent, so they can be applied in microwave dielectric materials, which play an important role in high-frequency and high-speed (e.g. 5G) communications.

Cryogenic liquid storage equipment: In the field of insulation materials for cryogenic liquid (e.g. liquid hydrogen, liquid helium) storage equipment, glass beads also show strong competitiveness. The use of glass beads + low vacuum insulation program can significantly reduce the thermal conductivity and improve the insulation performance.

In summary, glass beads (especially glass beads) are widely and importantly used in the aerospace industry, they not only improve the performance and safety of aircraft, but also promote the continuous development of aerospace technology.
