Impact resistance and impact resistance testing machine
Abstract:
耐冲击性指涂膜在承受高速率的重力冲击时，能够迅速变形而不出现开裂或从基材上脱落的能力。这一特性反映了涂膜的柔韧性和附着力。耐冲击试验常用ISO 6272-1993标准和GB/T 1732—93标准进行评估。ISO 6272-1993标准中的落锤试验采用1米高度、1千克重的冲击锤，冲头直径为20±0.3厘米。而GB/T 1732—93标准中也使用1千克的冲击锤，通过测试涂膜能够承受的最大高度来评估其耐冲击性，单位为厘米。这些试验方法确保了涂膜在实际应用中的稳定性和可靠性。
Impact resistance refers to the ability of the coating film applied on the substrate to undergo rapid deformation under high-speed gravity without cracking or falling off from the metal substrate. It shows the flexibility and resistance of the tested coating film. Substrate adhesion.
ISO 6272--1993 drop weight test, the height of the impact instrument is 1m, the weight of the hammer is 1kg, and the diameter of the punch is (20±0.3)cm. For the Chinese GB/T 1732-93 impact Tester, the weight of the hammer is also 1kg, which is represented by the maximum height that does not cause damage to the paint film, and the unit is cm.
