Discussion on in-situ test method of graphite XPS external thermal insulation composite systems
This dissertation addresses the discrepancy between the results of laboratory tests and field tests of Graphite-XPS exterio rinsulation system,by analyzing and studying the test results of mechanical properties of Graphite-XPS board and its exteri-or insulation system under the different test conditions.The reasons for this discrepancy are analyzed from the point of view of the material itself,the test method and the testing instrument.The test result of the universal testing machine is higher than that of the puller.Under the same test conditions,the test result with metal frame is slightly higher than that without metal frame,and the data discretization is relatively small.When the same test equipment is used,the test result under laboratory conditions is higher than that under field conditions.
