INSPECTION AND RESEARCH ON SITE REFLECTIVITY OF HEAT REFLECTION COATING FOR BUILDING

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.
