Sensitivity comparison of environment-friendly water-based fluorescence penetrant

Reference test blocks and artifactitious defect blocks were inspected by different type of internal and external water base fluorescent penetrant. The results of the sensitivity were analyzed and contrasted to different internal and external water base fluorescent penetrant. The advantage and disadvantage of water base fluorescent penetrant were concluded, and the feasibility about that water base fluorescent penetrant is used in aerostatical field was discussed. The result may be referred by craft brothers.
