Visible Dye Penetrant Testing Kit JB/T7523 Solvent Removable High Sensitivity

1. Pre-cleaning: Thoroughly clean all contaminants (scale, rust, grease, etc.) from the surface of the workpiece being inspected using a detergent.
2. Penetration: Allow the workpiece and test block to dry for 5-10 minutes before applying the penetrant. Hold the nozzle 20-30mm from the workpiece and test block. Penetration should be performed according to the instructions, typically for 5-15 minutes. During this time, the inspection surface should be fully moistened with the penetrant.
3. Cleaning: Use detergent or water (water pressure ≤ 1.5 kg/cm²) to scrub the penetrant off the workpiece surface.
4. Development: After thoroughly mixing the developer, spray it evenly at a distance of 300mm from the workpiece being inspected. Defects can be observed shortly after application.
5. After inspection, remove the developer by scrubbing with detergent or water.
6. Process and store the workpiece according to process requirements.

• Rapid penetration and rapid imaging;
• Suitable for solvent cleaning or water pre-cleaning followed by solvent re-cleaning;
• Lower fluorine, chlorine, and sulfur content than other similar products, suitable for inspecting ordinary austenitic stainless steel components;
