2. Basic requirements and challenges of thermal insulation materials in nuclear energy facilities

The insulation materials of nuclear energy facilities play a crucial role in ensuring the safe operation and high efficiency of the facilities. These materials not only need to have excellent insulation properties, but also meet a series of strict safety and performance requirements. First, insulation materials must have excellent high temperature resistance to cope with the high temperature environment generated by nuclear reactors. Secondly, the material needs to have good radiation stability and be able to maintain its physical and chemical properties under long-term exposure to high doses of radiation. In addition, insulation materials should also have excellent mechanical strength and durability to withstand various mechanical stresses and environmental erosion during facility operation.

In practical applications, thermal insulation materials of nuclear energy facilities face many challenges. High temperature environments may lead to thermal degradation and degradation of the material, which will affect the insulation effect and facility safety. High doses of radiation may cause radiation damage to the material, causing changes in its physical and chemical properties, which in turn affects its long-term stability. In addition, the complex operating environment of nuclear energy facilities, such as humidity, chemical corrosion, etc., also puts forward higher requirements on the performance of insulation materials.

To meet these challenges, researchers and engineers continue to explore and develop new insulation materials. As a new material, DMAEE dimethylaminoethoxy has shown significant advantages in thermal insulation materials for nuclear energy facilities due to its unique chemical and physical properties.
