测定金属表面的抗开裂性和抗剥离性
将涂漆试板绕在圆柱形轴上，即可知道已知直径轴上漆膜是完好还是破坏，同时还可以进行破坏点的测试
即依次换上直径较小的圆柱轴，观测直径小到什么尺寸时漆膜发生开裂
试办宽度可达50mm,厚度可达1mm
Cylindrical Mandrel Bend Tester
Used to test the resistance of a coating of paint, varnish or related product to cracking or detachment from a metal panel, after the panel has been bent around a cylindrical mandrel. It can be used as a simple Pass/Fail test at a known diameter, or as a Point of Failure test, by using successively smaller mandrels until cracking is observed.
Accepts panels up to 50mm wide and 1mm thick.
The following stainless steel mandrels are supplied:
2, 3, 4, 5, 6, 8, 10, 12, 16, 20, 25, 32mm diameters.
