Thermal Insulation Performance Analysis of Aerogels
Aerogels have excellent thermal insulation performance, and their thermal conductivity is about 100 times smaller than that of silica glass. Therefore, a large number of aerogel composites have been developed and are widely used in many fields such as building insulation and industrial insulation. As one of the most critical performances, thermal insulation performance provides basic data support for the application of aerogels and aerogel composites. Alfa Chemistry is at the forefront of the research and development of aerogels. Our team consists of experienced scientists who have a deep understanding in the thermal insulation performance of aerogels and their potential applications. We look forward to being your project partner.
Calculation Methods
Thermal conductivity represents the thermal insulation performance of aerogels. The lower the thermal conductivity, the better the thermal insulation performance. Our methods for calculating the thermal conductivity of aerogels include the decoupling method, equivalent circuit method and numerical simulation method. The disadvantages and advantages of these calculation methods are briefly summarized in table 1. No matter which method is used, we will also modify the mathematical models for different working conditions of aerogels.
Table 1. The disadvantages and advantages of the above three calculation methods.
| The Common Methods | Disadvantages | Advantages |
| Decoupling method | The porous structure of aerogels is ignored. | The method is simple in form and convenient in calculation. |
| Equivalent circuit method | For different aerogels, the structural model needs to be rebuilt. | This method can reflect the influence of material structure on thermal conductivity. |
| Numerical simulation method | The calculation method is complicated and only discrete numerical results can be obtained. | The method is accurate enough to take into account the influence of various factors on heat transfer. |
Test Methods
In order to verify the accuracy of the thermal conductivity calculation model of aerogels, correct test data are required to modify the model. Our test methods mainly include heat conduction heating test method, infrared radiation heating test method, and convection heating test method. The disadvantages and advantages of these methods are briefly summarized in table 2. We will choose the best test method based on the actual situation of your project.
