Discussion on the Safety of Aerogel Insulation Materials and Their Applications

Hits: 26 img

Aerogel insulation and heat preservation material is based on inorganic materials such as silica and alumina. These components remain stable under normal conditions and do not decompose or release harmful substances, thus being regarded as non-toxic. Through sophisticated manufacturing processes, including sol-gel method and supercritical drying method, these materials are meticulously made into nano-scale porous solids. The internal pores are mainly occupied by air, making aerogel insulation and heat preservation materials a high-quality material that is environmentally friendly and harmless to the body. 
01 Safety Performance Advantages
Non-toxic and Odorless
Unlike some traditional insulation or decorative materials that may release volatile organic compounds such as formaldehyde and benzene, aerogel materials remain non-toxic and odorless during use. Its unique nanoscale porous structure not only has high adsorption capacity but also effectively purifies particles and toxic gases in the air, thereby improving indoor air quality.
For example, choosing aerogel as insulation material during interior decoration can ensure that occupants are free from the annoyance of pungent odors and enjoy a healthier and more comfortable living environment.
Excellent Chemical Stability
Aerogel exhibits outstanding chemical stability and is not prone to chemical reactions with air, moisture, etc. This stability enables it to maintain stable performance over a long period of use, ensuring that it does not pose potential risks to human health. 
02 Precautions During Use
Although the aerogel material is generally safe, during its processing and preparation, the following points still need to be noted to ensure safe use: 
Processing procedure
During the processing of aerogels, improper additives or processes should be avoided to prevent the introduction of potential harmful substances. To ensure the safety of the selected products, it is recommended to purchase aerogel products from reputable manufacturers that have undergone quality inspections. 
For instance, some inferior aerogel sheets may release harmful substances during use due to excessive addition of adhesives. 
Preparation process
During the preparation and installation stages of the aerogel, precautions must be taken to prevent the generation of dust and volatile organic compounds, which may have an impact on the health of construction workers. Therefore, construction workers should be equipped with personal protective equipment such as masks and gloves to reduce the risk of inhaling dust and harmful gases. After the construction is completed, ensure adequate ventilation to guarantee that the indoor air quality meets the standards.
Aerogel insulation and heat preservation materials, this new type of insulation material, is playing an increasingly important role in various fields such as construction and industry. Usually, aerogel materials do not release harmful substances to the human body. However, to ensure its safe use, we still need to choose regular products when purchasing and use and maintain them properly.
