Aerogel Thermal Coating

 

Key Properties：

1. A variety of heat transfer barrier: the aperture of the aerogel insulation coating is generally concentrated at 50nm, and the average free path of air molecules is less than 70nm, and the air molecules in the pores lose the free flow ability to avoid the convective heat transfer of air; The multi-nanopore structure makes the heat flow transfer in the solid only along the pore wall, forming a long thermal conduction path, which prevents the solid heat conduction. Each pore wall inside the material acts as a heat shield, reducing the radiation heat transfer to a near minimum limit.

 

2. Sound absorption and noise reduction: the pore structure can absorb and scatter sound, effectively reduce noise. For example, in some places with high acoustic environment requirements, such as concert halls and recording studios, the use of aerogel thermal insulation coating can improve the acoustic effect and reduce noise interference.

 

3. Safe and reliable: aerogel thermal insulation coating has good electrical insulation performance, which can effectively prevent the conduction of current and improve the safety during use. In the heat insulation protection of some electrical equipment and electronic devices, it can not only play the role of heat insulation, but also ensure the electrical insulation performance.

1. Aircraft thermal insulation: It can effectively prevent the invasion of external thermogens such as cosmic radiation and solar radiation to the inside of the spacecraft, reduce the heat loss from the inside of the spacecraft to the outside space, and ensure the stability and safety of the internal temperature of the spacecraft.

2. Engine heat insulation: Aerogel heat insulation coating can withstand thermal shock in high temperature environment, effectively isolate the thermal impact of high temperature gas generated by the engine on the surrounding structure, and protect the core components such as the engine housing from high temperature damage.

3. Engine cabin insulation: It can reduce the internal temperature of the engine cabin, improve the efficiency of the engine, reduce energy waste, and protect other components in the engine cabin from high temperature.

4. Exhaust pipe heat insulation: can effectively block the heat emitted by the exhaust pipe, prevent heat transfer to other parts of the body, reduce the interior temperature, improve ride comfort, but also reduce the thermal impact on the vehicle surrounding environment.

5. Heat dissipation and insulation: aerogel thermal insulation coating can help reduce the temperature of electronic products, improve their performance and reliability, such as in mobile phones, computers and other equipment, can prevent heat accumulation, extend the service life of the equipment.

6. Battery protection: In new energy vehicles and energy storage systems, the application of aerogel thermal insulation coating to the thermal insulation layer design of the battery pack can effectively block the heat generated inside the battery pack, prevent thermal runaway, and improve the safety and service life of the battery.

1. How is the compatibility with different base materials?
It can be combined with a variety of base materials, such as metals (steel, aluminum, etc.), ceramics, glass and plastics. For the metal matrix, the coating can be tightly attached by chemical bonding or physical adsorption. On ceramic and glass substrates, the active groups on their surfaces can be used to form a firm bond. For the plastic matrix, by choosing the right binder, the coating can be well attached to its surface, and will not have an adverse effect on the performance of the matrix material.

2. Can the supplier provide construction technical support?
Able to provide construction technical support. This includes the provision of detailed construction instructions, which cover the surface treatment before construction, the construction method (such as the specific operation points of spraying, brushing), the construction environment requirements (temperature, humidity range), coating thickness control, etc. In addition, some suppliers can also provide on-site technical guidance, or train the buyer's construction personnel to ensure the best construction quality.

3. What special shapes or structures can it be applied to?
It can be applied to a variety of complex shapes of objects, such as curved parts of pipes, irregularly shaped equipment enclosures and so on. This is because it can be constructed by spraying and other methods, can be uniformly covered on the surface of the object, and the thickness of the coating can be adjusted according to the shape of the object, so as to effectively achieve the purpose of heat insulation.

4. What should I pay attention to during storage and transportation?
When storing, it should be stored in a dry, cool and well-ventilated warehouse to avoid direct sunlight and wet environment to prevent the coating from being spoiled by moisture. At the same time, keep away from fire sources and combustible materials, because some coating components may have a certain degree of flammability. During transportation, ensure that the package is intact, avoid collision, extrusion and jolting, and prevent breakage and leakage of coated containers. For long-distance transportation, it is also necessary to pay attention to the control of temperature and humidity, and appropriate protective measures can be taken if necessary, such as the use of refrigerated trucks or moisture-proof packaging.

5. What are the main raw materials? What effect do these raw materials have on coating properties?
The main raw material is aerogel, usually silica aerogel, and also includes binders, additives, etc. Aerogel is a key component that determines the thermal insulation performance of the coating, and its nanoporous structure gives it a very low thermal conductivity, which can effectively block heat transfer. The role of the binder is to bond the aerogel particles together and make the coating firmly adhere to the surface of the substrate, and the performance of the binder will affect the adhesion and durability of the coating. Additives can improve some properties of the coating, such as fire resistance, water resistance and so on.
