【 摘 要 】

The steady-state calorimetry technique was used to measure the total hemispherical emissivity of thermal insulating coating, after testing the the total hemispherical emissivity of thermal insulating coatings, the result showed that with the gradual increase of the test temperature, the hemispherical emissivity of heat insulation coating decreases as a whole, and with the increase of temperature, the radiation ability of heat insulation coating is reduced.
