Compared with traditional materials, aerogels can achieve better results with a lighter weight and smaller volume. Aerogels have the advantages of heat insulation, high temperature resistance, noise reduction, explosion prevention, adsorption, corrosion resistance, catalysis, light transmission, low dielectric constant, etc. They can be widely applied in aerospace, military, integrated circuits, chemical industry, new energy and other fields.
1. Heat insulation, high temperature resistance
Due to the existence of nearly infinite nano pores in aerogels, the heat flow in the solid can only be transmitted along the walls of the pores. The nearly infinite number of pore walls form an "infinite long path" effect, reducing the solid's heat conduction ability to nearly the lowest limit. Aerogel mats can be used for insulation in fixed places such as warehouses, refrigeration rooms, and specially designed tents, and can also be used for insulation in mobile places such as battlefield command vehicles, constant temperature transportation boxes, locomotive heat sources, and precision instrument storage boxes. Aerogel can be made into aerogel mats or fabrics with different properties in terms of insulation, strength, flexibility, and extensibility, which can be applied in armored tanks, aircraft cockpits, extreme environment camp tents, boiler heat sources, bedding clothing, helmet inner linings, military uniforms for winter, and fire-fighting clothing, etc.
Ⅰ. Spacecraft cabin building materials, which can achieve heat insulation, heat preservation, impact prevention, radiation prevention, static electricity prevention, and corrosion prevention, and can effectively reduce the weight of the spacecraft itself; the outer coating of the return capsule can achieve heat insulation effect when returning through the atmosphere.
2. The production of spacesuits, achieving heat preservation, impact prevention, radiation prevention, etc.
3. Materials for planet exploration vehicles, protection of precision components of extraterrestrial exploration equipment (radiation prevention).
4. Adsorption and capture of space particles.
The same characteristics can also be applied in the military field. The aerogel from Keyuan can be used in:
1. Outer materials for aircraft, ships (boats), tanks, missiles, etc. (radiation prevention, absorption of infrared and diffuse reflection waves, achieving stealth function by avoiding detection; shielding own electronic signals to achieve anti-spy. ) Internal parts (static electricity treatment, insulation and heat preservation system) External equipment (control cabin glass, tracks, tires, etc. explosion treatment.)
2. Aerogel composite perlite insulation houses, fighter aircraft bulletproof shelters, composite fiber insulation tents.
Ⅱ. Explosion prevention
By taking advantage of the characteristics of aerogels, we can apply aerogels in environments that require explosion-proof, such as tanks, armored vehicles, aircraft, storage facilities, power facilities, etc. In fact, in recent years, foreign armies have begun to gradually apply aerogels in heavy vehicles such as tanks and armored vehicles. Aerogel composite bulletproof clothing, infrared-avoiding clothing fabrics (invisible clothes), etc.
Ⅲ. Purification
The adsorption effect of aerogels can be manifested in forms such as absorption, repulsion, and purification.
For example, combining aerogel with anti-toxic charcoal, the combined anti-toxic charcoal adsorption effect is greatly improved due to the nano mesoporous structure of aerogel. At the same time, the stable chemical properties of aerogel make it very advantageous as a catalyst carrier, and various types of catalysts can be used, and various types of anti-toxic masks can be made according to needs.
Ⅳ. Noise reduction, noise suppression
Aerogels are filled with nano pores that are open at both ends and connected to the surface, and it is a relatively ideal acoustic coupling material and stealth material for ultrasonic detectors. If applied in the military field, it can achieve sound insulation and noise reduction for aircraft, ships (boats), tanks, etc., especially for submarines' sound insulation and noise reduction; sound insulation and noise reduction for mobile and fixed command posts and other military facilities; and it can also be used to manufacture stealth coatings for stealth aircraft, vehicles, etc.
Ⅴ. Other
Aerogels can also be used in the manufacturing of components for supercomputers, satellite detection systems, electronic control systems, etc.; to extend the service life of lead-acid batteries (used in aircraft, ships (boats), tanks, etc.).
