WEICON Rissprüfmittel 裂纹测试剂 颜料渗透测试是一种常见的、非破坏性的测试方法,可方便、快速地检测出部件和机器表面是否存在缺陷。 金属、多种塑料、陶瓷材料和玻璃等,均能通过这种方式进行安全、可靠的检测。 测试前需确保材料表面完全暴露。 该测试方法多用于检测焊缝和铸造部件,在造船、汽车、仪器制造等诸多行业广泛使用。 颜料渗透测试 颜料渗透测试的第一步骤是对被测部件进行表面清洁、去脂,然后再喷洒扩散剂。 渗透测试的原理是,利用蠕变特性出色的有色扩散剂,让其覆盖物体表面,渗透进表面裂纹和缺陷处。 依具体材质、环境温度等的不同,扩散剂渗透数分钟后,需使用特殊的清洁剂将多余的、未渗透入裂纹与缺陷的扩散剂清除。随后喷涂催化剂,它会将渗透进裂纹里的扩散剂的色素吸附至材料表面,使裂纹部位显色。 催化剂是一款细颗粒的粉末,它的毛细孔性能优越,能将裂纹和毛细孔里的扩散剂吸附至材料表面。因此,凡表面出现裂纹及缺陷的地方会呈现出线状或点状的红色,便于视觉检测。 颜料渗透测试的步骤 1、使用特殊清洁剂清洁材料表面 2、喷洒扩散剂并让其渗透数分钟 3、再次清洁材料表面 4、喷涂催化剂 5、视觉检测 Crack Testing Agent Penetrant Cleaner, Penetrant and Developer for the non-destructive material testing by way of colour penetration process Red diffusion agent with excellent penetration characteristics for the non-destructive material testing - washes off with solvent.
