Passes a 400-mesh screen, with an average particle size of approximately 6 to 8 micrometers.
Available in YC-2, 400 mesh, and NY-20, 500 mesh, for fluorescent magnetic-particle inspection of surface and near-surface defects in ferromagnetic workpieces.
Fluorescent magnetic particle is an inspection material for ferromagnetic materials. After a workpiece is magnetized, leakage fields form around surface or near-surface defects. Magnetic particles in the suspension gather at these leakage fields and form clear fluorescent indications under long-wave ultraviolet illumination.
This series includes YC-2 and NY-20. The two models differ in particle fineness, suspension concentration, carrier liquid and preparation method. Select the product according to the inspection process.

Fine 500-mesh particle suitable for water-based fluorescent magnetic-particle inspection.
Add 5 to 8 g of NY-20 fluorescent powder per liter of water suspension.
This model is for water suspension only and is not intended for oil suspension.
Measure the powder accurately according to the model, carrier volume and recommended concentration.
Add the powder to dispersant or a small amount of water so it becomes fully wetted.
Mix thoroughly until a uniform paste without obvious dry clumps is formed.
Add water slowly, then start agitation and spray circulation after adding the mixture to the tank.
Check the tank, pipes and suspension paths for foreign matter. Start agitation and spray circulation and inspect the returning water or oil. Clean the system immediately if contamination is present.
Prepare the suspension at the recommended concentration for YC-2 or NY-20. First make a paste with a small amount of carrier, then dilute it gradually and add it to the equipment tank.
Start agitation and spray circulation so the particles remain uniformly dispersed. Maintain suitable circulation throughout the inspection.
Select the magnetization method, field direction and magnetizing current according to the material, dimensions, shape, surface condition, defect direction, inspection method and effective inspection area.
Place an A-type test piece closely against the workpiece surface with the grooved side facing the workpiece. Do not cover the grooves with adhesive. Continue inspection only when the circular and cross indications are clearly visible.
Observe fluorescent particles under long-wave ultraviolet illumination that meets the inspection requirements. Warm up the ultraviolet lamp and wait for stable output before inspection.

Actual inspection and acceptance should follow the currently applicable standards and process documents for the user's industry and workpiece type.
Choose YC-2 when water-based or oil-based suspension is required. NY-20 is a 500-mesh product for water suspension only and requires no additional additive.
Wet the powder with YF-1 dispersant, mix it into a paste, gradually add the required water and mix thoroughly.
Mix the powder into a paste with a small amount of FM-3 inspection carrier, then add the remaining carrier and mix thoroughly.
No. NY-20 is intended for water suspension only.
No. A concentration that is too low may miss small defects, while a concentration that is too high may increase background and reduce the clarity of defect indications.
It verifies the combined sensitivity of the magnetic powder, suspension, magnetizing equipment and inspection process before formal inspection begins.
