Magnetic Particle Inspection "MAGNATRON"
Magnetic particle inspection materials
MAGNATRON gives a good contrast of any defects against the background and has high sensitivity. The desired one can be selected out of abundant types. And also, BLENDEX and MAGNATRON OIL can suspend magnetic particles very well.
Magnetic particles
Fluorescent magnetic particles
Fluorescent magnetic particles show brilliant fluorescent under black light. Even a lower concentration of suspension, 1g/liter, achieves higher sensitivity.

Aerosol type
Aerosol cans in which a correct amount of fluorescent magnetic particle is suspended in an oil. Simply spraying detects any defects quickly. Three types of particles are provided: SY-7500, SY-7500Special,SY-8000, and SY-8000XB. In addition, Water-based SY-8000W is offered.

To use magnetic particles in water, any conditioner should be applied. Be sure to prepare particles and the conditioner, Blendex, into a paste form before putting into water.
You can see it by scrolling horizontally.
| TYPE | APPEARANCE | RECOMMENDED CONCENTRATION | FEATURES |
|---|---|---|---|
| Blendex-B | Light milky white, viscous liquid | 0.5-2.0% to water | Regular type, Well suspended. |
| Blendex-D | Non-foaming, use when bubbles foaming during circulation of magnetic particle solutions. | ||
| Blendex-RH | 3-5% to water | Strong rust-prevention. Can paint directly the parts without cleaning after inspection. |
MAGNATRON OIL(Oil for particle suspension)
Use this oil product instead of kerosine to suspend magnetic particles in oil. Due to its flash point of above 94℃, it is less flammable than kerosine at normal temperature and even odorless.
Resmine(Antirust )
Adding this rust preventive product to a magnetic particle water solution prevents the tested objects from rusting for several days after inspection. (Adjust the amount depending on your requirement.)
Resmine・・・・・Used for general steel materials. Add 1-5% to magnetic particle suspension.
Resmine-C・・・Suitable for casting materials. Add 0.5-5% to magnetic particle suspension.
