2022-02-19

1. Immerse the workpiece in a beaker filled with 3500P fluorescent penetrant, take it out immediately, and leave it for 10 minutes. Since there will be sagging during the placement process, use a dropper to add penetrant on the way.

3. Use 3500R special emulsifier (1:4 dilution), drop the dropper on the surface of the workpiece, observe the emulsification state under a black light, rinse it off with tap water after 1 minute after the emulsification is complete (there is no fluorescent background on the surface under the black light, emulsification agent residue), shake off the surface water droplets.
