Description

Technical Field

[0002] Building energy-saving materials refer to materials used in construction projects that can improve building energy utilization, reduce energy consumption, and reduce environmental impact. As the global energy crisis becomes increasingly serious, the research and application of building energy-saving materials have become increasingly important. Common building energy-saving materials include thermal insulation materials and heat preservation materials. These materials have good thermal insulation properties and can effectively prevent heat conduction and radiation, reduce the temperature difference between the inside and outside of the building, reduce building energy consumption, reduce the energy consumption of air conditioning and heating systems, and improve the energy-saving performance of the building.

[0003] Thermal conductivity is an important parameter for measuring the thermal insulation performance of materials. The smaller the thermal conductivity, the better the thermal insulation performance. A higher thermal conductivity will affect the energy-saving effect. When measuring the thermal conductivity of energy-saving materials, the temperature difference measurement method is usually used. However, when the energy-saving materials are placed in the device, it is inconvenient to clamp and fix the device, and the device is prone to tilt and fall. Moreover, when the energy-saving materials are taken out after the test, due to the high surface temperature of the energy-saving materials, there is a safety hazard of burns when taking them out manually. Therefore, improvement is urgently needed. Utility Model Content
