摘要
太阳反射比是表征建筑热反射涂料的重要指标,由于检测设备体积庞大,多数检测在实验室完成,急需能够在现场即时检测热反射涂料反射率的仪器。通过U-4100分光光度计和便携式分光光度计对试件进行检测,得出:新型研发的便携式分光光度计能够覆盖350～2500 nm波段,可在现场方便地对已施工完毕的建筑热反射涂料进行反射率检测,并能输出反射率数据,为建筑热反射涂料的验收提供了保证。
Solar reflection ratio is an important factor for evaluation of heat reflection coating for building. But the testing equipment is very huge, so most of the tests are carried out in laboratory and instrument for site test of heat reflection coating is in urgent demand. The test is carried out by using U-4100 spectrophotometer and portable spectrophotometer, and it is found that the newly-developed portable spectrophotometer is applicable to 350-2500 nm wave band, it could be conveniently used to test the reflectivity of heat reflection coating for building after construction and could feed back reflectivity data to guarantee the successful acceptance of heat reflection coating for building.
