1. High adsorption efficiency: with huge specific surface area and nanoscale porous network structure, it provides a large number of active sites for adsorption, and can quickly and efficiently adsorb various target substances, such as the adsorption capacity of silicon aerogel for benzene, formaldehyde, acetaldehyde, ammonia and other gases is several times higher than that of granular activated carbon.
2. Adsorption selectivity: By regulating the pore size, shape and surface chemical properties of aerogel, selective adsorption of specific substances can be achieved, and aerogel adsorption coatings can be designed to absorb a certain or a certain type of substances according to different application needs.
3. Good fire and flame retardant: aerogel itself is a flame retardant substance, can effectively prevent the spread and spread of flame, in the event of fire, can delay the development of fire, for personnel evacuation and fire rescue time, improve the fire safety level of the use of places.
application
1. Building field: It can be coated on the exterior wall, roof and floor of the building, which can effectively reduce the heat transfer inside and outside the building, significantly reduce the temperature difference between indoor and outdoor, and also improve the fire resistance of the building; It can also be used to manufacture composite materials such as aerogel thermal insulation mortar and aerogel glass to improve the overall thermal insulation and energy saving effect of buildings.
2. Aerospace field: The thermal protection layer for spacecraft can prevent the invasion of external pyrogen such as cosmic radiation and solar radiation, reduce heat loss, and ensure the stability of the internal temperature of the spacecraft; It is also widely used in the design of aerospace engine insulation layer, which can withstand high temperature thermal shock and protect core components such as engine housing.
3. New energy field: In new energy vehicles, the heat insulation layer for the battery pack can prevent the battery from getting out of control, improve safety and service life, reduce the overall quality of the battery pack and increase the driving range; As a heat insulation layer in the solar collector, it can reduce heat loss and improve the efficiency of solar energy utilization. In the storage and transportation of hydrogen energy, it can block the external influence of low temperature on liquid hydrogen and reduce evaporation loss.
FAQ
1. Does the thermal insulation performance of the coating decrease over time?
It has good weather resistance and anti-aging performance, is not easy to crack, fall off, insulation effect decay and other problems, and its service life can reach more than 10-15 years, which is 3-5 times longer than that of traditional insulation materials. Of course, in extreme environments or when subjected to long-term severe physical and chemical effects, the thermal insulation performance may decline to a certain extent, but overall it is relatively stable.
2. Is the construction difficult?
Construction is relatively simple. It can be sprayed, brushed, scraped and other construction methods, which can adapt to the needs of different structures and surface forms, and easily and quickly form uniform and continuous insulation layer in equipment, pipelines and other parts, without complex fixing and splicing processes, and the skill requirements of construction personnel are not high.
3. In high humidity environment, will the thermal insulation performance of the coating be affected?
Most coatings have good hydrophobicity and can effectively resist water vapor erosion. In a high humidity environment, water is not easy to penetrate into the coating, so its thermal insulation performance is basically unaffected. However, if you are underwater or immersed in a large amount of water for a long time, there may be some challenges to the durability of the coating, and the specific situation needs to be judged according to the product characteristics.
