In recent years, new thermal insulation materials aerogel and its products have gradually appeared in the public's vision, and its excellent thermal insulation, fire prevention, sound absorption and other properties have been recognized by the public. Although the names of aerogel and aerogel felt look similar, there are significant differences in structure, morphology, and application.

1. Form

Aerogel is a solid material with a high pore structure and very low density, usually in the form of powder, block or particle. It is usually prepared from a gel form of a solid material, by removing the liquid in the gel, making it light and porous.

Aerogel felt is a flexible thermal insulation material made of aerogel as raw material, mixed with other materials (such as reinforced fibers, adhesives, etc.), and then pressed, dried, cut and other processes. It also has light weight, high strength and high insulation properties, but it is structurally different from aerogel.

2. Application

Aerogel has a high specific surface area and pore volume, which makes it widely used in various fields. For example, in the aerospace sector, aerogel can be used as a highly efficient thermal insulation material, absorbing and blocking the transfer of heat; In the field of chemical engineering, aerogel can be used as catalyst or catalyst carrier to improve the efficiency of chemical reaction and product purity; In the field of environmental protection, aerogel can be used for air purification and sewage treatment.

Aerogel felt has excellent thermal insulation properties and durability, and is widely used in construction, industry, aerospace, automobile manufacturing and other fields as thermal insulation and insulation materials. Due to the excellent thermal insulation performance of aerogel felt, it can effectively reduce energy consumption and waste, and help achieve the goal of energy conservation and emission reduction.

3. Summary

Although aerogel and aerogel felt have excellent thermal insulation and insulation properties, their application fields are different. Because of its high porosity and specific surface area, aerogels have wide application prospects in catalyst support, adsorbent, sensor and other fields. Aerogel felt is widely used as thermal insulation material in construction, industry, aerospace, automobile manufacturing and other fields because of its flexibility, easy cutting and inorganic fire prevention.
