In recent years, aerogels related products have gradually appeared in the public's vision and have been widely concerned. As a new type of thermal insulation material, silica nano aerogel felt has been vigorously promoted by the country. What properties of silica nanoaerogel felt are worthy of national attention?

First, let's take a look at the basic characteristics of silica nanoaerogel felt. It is made of silica aerogels with a large number of nano-holes in the internal structure, and is made of glass fiber or pre-oxidized fiber to increase its mechanical properties. This material has a low thermal conductivity (0.015-0.025 W/(m·K)) and is able to maintain stable performance at high temperatures, while also having good compression, tensile strength and durability.

In terms of thermal insulation, silica nano aerogel felt has excellent performance. Its thermal conductivity is much lower than that of traditional thermal insulation materials, which can achieve the same thermal insulation effect at a thinner thickness. This means that in the insulation of equipment and pipelines, the use of silica nanoaerogel felt can greatly reduce the thickness of the insulation layer, reduce heat loss, and improve energy efficiency.

In addition, silica nano aerogel felt also has excellent heat resistance. Thanks to its unique nanoscale three-dimensional network structure, the material is able to maintain stable performance in high temperature environments, avoiding the problems of deformation and decreased thermal insulation performance caused by vibration of traditional materials. This makes silica nanoaerogel felt ideal for high temperature equipment, such as industrial pipes, storage tanks, high temperature steam pipes, etc.

In addition to thermal insulation and heat resistance, silica nanoaerogel felt also has good compressive strength, tensile strength and crack resistance. This makes the material not easy to deform and settle during long-term use, and can maintain a durable thermal insulation effect. In addition, silica nanoaerogel felt also has excellent waterproof properties and sound insulation and seismic functions, making it an ideal insulation material for a variety of complex environments and equipment.

It is worth mentioning that silica nano aerogel felt also has the advantages of environmental protection. As an inorganic non-metallic material, it does not contain harmful substances to the human body, and the soluble chloride ion content is very small. This allows the material to hold heat while also meeting the requirements of environmental protection and health.

In terms of transportation and storage, silica nanoaerogel felt also has obvious advantages. Due to its small size and weight, transportation and storage costs can be significantly reduced. At the same time, the lightweight, convenient and easy to cut characteristics of the material also improve the construction efficiency and adapt to various complex shape requirements.

As a new type of thermal insulation material, silica nano aerogel felt is becoming an ideal choice in the field of thermal insulation with its excellent performance and environmental protection advantages.
