Abstract:
本文以Defelsko品牌的几款热门拉开法附着力仪为研究对象，对它们的选型参数进行了详细对比。拉开法附着力仪主要用于检测涂层从底材上剥离的能力，通常分为数显式和机械式两种类型。对比结果显示，ATM50A-B和ATM20A-B属于数显式仪器，测量范围分别为50-560psi（0.43.8MPa）和100-3500psi（0.724MPa），精度均为±1%满量程，分辨率可达±1psi（0.01MPa）。ATM50A和ATM20A则为机械式仪器，测量范围分别为100–3000psi（0.720MPa）和0-3000psi（0~20MPa），精度同样为±1%满量程。从应用领域来看，ATM50A-B和ATM50A适用于混凝土、木材和塑料涂层的剥离检测，而ATM20A-B和ATM20A则主要用于金属涂层的剥离测试。用户可根据实际需求选择合适的仪器类型和参数设置。
