防腐层抗弯曲试验仪用于色漆、清漆和相关产品涂层绕圆柱轴弯曲时抗开裂性和从底材剥落性能的

测试。

The anti-corrosion layer bending tester is used to test the crack resistance and peeling performance of the substrate when the paint, varnish and related product coatings are bent around a cylindrical axis. test.

防腐层抗弯曲试验仪可用于厚度不大于1mm的试板，只要能保证轴不发生变形，也可用于较厚的软金属如铝试板、镀锌板、塑料试板。对于厚度大于0. 5mm的试板，建议避免使用直径小于10mm的轴进行试验。

本仪器适用于GB/T6742-86JT/T374-1998《隔离栅技术条件》

JT/T281-2007《高速公路波形梁钢护栏》、

ISO1519-73 ASTMD522.

The anti-corrosion layer bending tester can be used for test plates with a thickness of not more than 1mm. As long as the shaft is not deformed, it can also be used for thicker soft metals such as aluminum test plates, galvanized plates, and plastic test plates. For test plates with a thickness greater than 0.5mm, it is recommended to avoid using shafts with a diameter less than 10mm for testing. This instrument is suitable for GB/T6742-86JT/T374-1998 "Isolation Barrier Technical Conditions" JT/T281-2007 "Highway Corrugated Beam Steel Guardrail", ISO1519-73 ASTMD522.
