Apparatus for evaluating thermal insulation effect of powder materials and its application method

Abstract

The invention provides a powder material heat insulation effect evaluation device and an application method thereof and relates to material testing conducted through heat conduction testing. A test main body of the device comprises a thermotank and a test box, temperature controllers are installed on the thermotank, the test box is divided into an upper part and a lower part, a sample tank is installed in the middle of the test box, a powder material to be tested can be directly placed into the sample tank for measurement, a stable test environment is provided, detection deviation caused by the environment temperature, pressure, airflow, coating formulas and other external factors is avoided, and the test result can have stability and repeatability. The invention further provides a corresponding evaluation method, in other words, heat insulation effect evaluation of the corresponding powder material is obtained according to the measured temperature through the evaluation method. By means of the powder material heat insulation effect evaluation device and the application method thereof, the defects that in the prior art, powder material heat insulation effect evaluation devices are unstable in constant temperature environment setting, inconvenient to carry and long in test cycle, and requirements are difficult to meet are overcome.

Description

technical field [0001] The technical solution of the present invention relates to testing materials by testing heat conduction, in particular a device for evaluating heat insulation effects of powder materials and a method for using the same. Background technique [0002] With the development of science and technology and the improvement of people's living standards, thermal insulation materials are widely used in production and life. Insulators are materials or composites that exhibit significant resistance to heat flow. Building thermal insulation is an important aspect of saving energy, improving the living environment and using functions. Building energy consumption generally accounts for 30-40% of the total energy consumption of human beings, most of which are heating and air conditioning energy consumption, so building energy conservation is of great significance. An effective way to reduce building energy consumption is to reduce the transfer of heat energy. For exa...
