BGD 561 铰链式圆柱芯轴弯曲试验机

描述

It is used to assess the pliability of the paint film through the capability that the paint film deforms with bottom material and does not get damage at the specified standard conditions. It is expressed with the minimum shaft stick diameter which does not cause the paint film to crack when the test plate moves around the shaft stick of 180° within 1-3 seconds at the specific conditions in the standard. It confirms to ISO 1519 ,ASTM D 522,DIN 53152.

This tester consists of eight hinges and each hinge has different diameter axis. Put the test panels into hinge then fold it and test panels then have finished 180° bend.
可以进行测试：

—作为“通过/失败”测试, 通过使用单个指定尺寸的心轴进行测试, 评估是否符合特定要求;

—或者通过使用连续较小的心轴重复该过程来确定第一个心轴的直径，在该直径上涂层会破裂和/或与基材分离.
