This paper looks to investigate the effects of any deviation from the required method in every aspect of the test. Each aspect is examined in turn, the results tabulated and the potential effect on a valid adhesion test result is discussed.JF Fletcher...
拉开法--测试方法Pull-offtestforadhesion 1)用砂皮打磨测试表面，使其平整，并清洁表面。2)试验用dolly表面用砂皮磨平，并清洁。3)在dolly的表面涂布胶水，放置于要测试的表面，并用胶带固定 4)等待足够的时间让胶水固化(但组分胶水1小时，环氧胶水1天)5)用工具切割dolly的四周.3-2用拉拔试验仪器拔下dolly并记...
