Nano-micro-porous insulation boards are a type of high-performance insulation material, with their insulation performance being 34 times that of traditional fiber materials. This material is made from special nano-inorganic refractory powders. Due to the extremely small contact points between the nano particles, the heat conduction and heat transfer effects are low, resulting in a very low thermal conductivity of the material. Nano particles form a large number of nano-sized pores, with an average pore diameter of 20nm, while the average free path of stationary air molecules at room temperature is 60nm. The stationary air molecules in these pores hardly undergo convective heat transfer, so the thermal conductivity of the product is even lower than that of stationary air. 
When using nano-microporous insulation boards, the following points should be noted: 
Packaging integrity 
The nano-microporous insulation board is produced by powder pressing during the manufacturing process. Therefore, during use, there may be powder shedding. To maintain the insulation performance of the product, it is necessary to ensure that the packaging is intact and undamaged. Avoid damaging the packaging during transportation or storage. If the packaging is damaged, appropriate measures should be taken promptly for repair or replacement to prevent powder from scattering and affecting the insulation effect. 
2. Moisture-proof and waterproof 
The main component of the nano-microporous insulation board is a hydrophilic material, which readily absorbs water. Once water is absorbed, the thermal conductivity of the material will significantly increase, thereby affecting the insulation effect. Therefore, during use and storage, the product should be avoided from coming into contact with damp environments or liquids. If it is necessary to use it in a humid environment, it is recommended to take additional waterproof measures, such as using waterproof films or coatings for protection. 
3. Installation Precautions 
When installing the nano-microporous insulation board, one should operate carefully to avoid damaging the product due to excessive force. During the installation process, it is necessary to ensure that the surface of the insulation board is flat and there are no cracks or gaps to guarantee the insulation effect. If any damage or deformation is found in the insulation board, it should be replaced immediately to ensure the overall insulation performance. 
4. Storage conditions 
Nano microporous insulation boards should be stored in a dry and well-ventilated environment, avoiding prolonged exposure to damp or high-temperature conditions. It is recommended to use sealed containers or packaging during storage to prevent the intrusion of moisture and dust. Regularly check the storage environment to ensure the integrity of the materials. 
Summary
Nano microporous insulation boards have been widely used in various fields due to their excellent insulation properties. However, to ensure their long-term performance and service life, it is necessary to pay attention to packaging integrity, moisture-proof and water-proof measures, installation operations, and storage conditions during use. By following these precautions, the insulation effect of nano microporous insulation boards can be fully utilized, improving energy utilization efficiency, and providing reliable insulation solutions for industrial and construction sectors.
