Nano grain size cesium tungsten bronze may be used in the preparation of thermal insulation coating, so that it may be applied in many fields requiring high thermal insulation and high transparency such as building window glass and automobile window glass. With the gradual popularization of such heat insulation materials, people hope to know the performance of such material. And the best way is to test it by themselves.
Therefore, experts have provided a test method for testing the thermal insulation performance of the coating material. The insulation space is prepared by using a foam board, the design insulation space size is 5*10*10.5 (cm2), and the ordinary glass piece area is 7*12 (cm2), the coating area is 6.4*11 (cm2); the bottom of the box is covered with a black iron plate, and the red water thermometer (100°C) is placed on the surface of the black iron plate.
The specific test process? Place the glass coated with heat-insulating coating on the window of the heat-insulated space, and let the film-coated part completely cover the windows in this space. Use a 250W infrared lamp to illuminate the windows at a vertical distance of 25cm. Record the thermometer reading with the change of irradiation time. The same method is used to test the temperature change of the blank window glass with time, and the comparison between the two could obtain the heat insulation effect of the heat insulating coating.
