Can SHERWIN permeate be used on steel? How to clean Sherwin permeate?
2023-09-21 17:39:35
SHERWIN penetrants can be used in aluminum, magnesium, brass, copper, cast iron, steel, stainless steel, carbides, Stellite, certain plastics and ceramics. The main points of the method are: penetration of the dye penetrant to the defect - removal of excess penetrant from the surface - display indication - check. Dark red indicates that defects will be marked.
The surface should be free of foreign objects and paint. Grease, oils, etc. prevent penetration and should be pre-cleaned with detergent/remover or solvent degreasing removal. Scale, sand, dirt, etc. trap the penetrant and impede removal, so a wire brush or similar pre-cleaning is required. Paint must be removed from the area to be tested.
Osmotic solution cleaning:
1. Apply detergent/remover to the parts or parts to be inspected.
2, let the cleaner stay on the part long enough to dissolve dirt or film.
3. Dry with a clean cloth.
4. Repeat as necessary.
5, after the final cleaning and wiping, leave time to dry before using the penetrant.
6. Check the day of cleaning.
Application penetrant:
1, spray or brush the parts or parts to be inspected, so that the surface is covered with penetrant.
2. If the penetrant returns as a drop, stop and clean the part again.
3, let the penetrant stay on the parts for 10-30 minutes.
4. Locating extremely fine-grained discontinuities may require longer penetration times.
Penetrant removal:
1. When sufficient penetration time is allowed, wipe the surface clean with a clean towel or cloth.
2. Repeat as necessary. Some surfaces just need to be wiped.
3. However, in general, excess surface penetrant is removed using a clean cloth that has been pre-moistened with a cleaner/remover.
4, do not wash the surface with detergent/remover, as this will weaken the sensitivity. Repeat this process with additional wipes until the remaining surface penetrant is removed.
