中文摘要:
      红外低发射率涂层容易产生鼓泡、脱落、磨损、划痕、积污等问题。为了保证红外低发射率涂层具有较长的使用寿命,需要对红外低发射率涂层在使用过程中的性能状态进行及时测量评估。采用便携式红外发射率测量仪和便携式红外热像仪对5种温度条件下的脱落、划痕和积污涂层进行对比测试,研究发现:脱落和积污对红外低发射率涂层的影响较大,划痕也将使得红外低发射率涂层的发射率增大,划痕宽度和划痕间距对发射率的影响程度需要及时定量地测量及评估;基于反射法的便携式发射率测量仪受测量区域的涂层粗糙度等表面状态影响较大,而便携式红外热像仪测量结果受温度影响较大。
英文摘要:
      With low infrared emissivity coating (LIREC) being easy to get bubble, shedding, wear out, scratch, dirt and other problems, the performance state of LIREC should be measured and evaluated in time to ensure the long service life of the LIREC. A portable infrared emissivity measuring instrument and a portable infrared thermal imager used to test the emissivity of shedding, scratching and fouling coating areas at 5 kinds of temperature are adopted. The result shows that the influence of shedding or fouling on the LIREC is comparatively larger, the scratching and the fouling also make the emissivity of LIREC larger. Therefore, the influence degree should be timely and quantitatively measured and evaluated. The measurement results tested by portable infrared emissivity tester are affected by the surface conditions of the measurement area such as surface roughness and so on. The measurement results tested by portable infrared thermal imager are more affected by temperature.
