Magnetic Particle Testing Chemicals
Magnetic Particle testing is suitable for the surface/sub-surface testing of ferro-magnetic materials. This method is based on the principle that iron sand shall be attracted by magnet. In this method the material or part to be tested is magnetized, then apply the magnetic particles to the objective surface. The magnetic particle shall be attracted by the leakage flux formed at the detect and forms an indication. The formed indication is as 10 or more times large as the defect in its width. So, we can detect the defect easily.
There are two types of magnetic particle, one is non fluorescent for the observation under white light, the other is fluorescent for the observation under UV light. The other categorization is based on the application; those are Dry method and Wet method, magnetic particle shall be applied to the surfaces at it stands. In Wet method, magnetic particle shall be dispersed in oil or water. Some water conditioner shall be used for water suspension usage for uniformity ensuring and wettability improvement.
In magnetic particle testing, the key role of flaw detection is performed by the powder. Hence, the quality of powder being used greatly influences the quality of the test performed. FlawGlo series includes all types of magnetic particles for different applications (i.e. oil based, water based & dry application) in both visible as well as fluorescent forms.
