荧光磁粉 这是一种在紫外线(黑光) 照射下进行磁痕观察的磁粉。荧光磁粉有水性和油性两种。

Fluorescent magnetic powder This is a kind of magnetic powder that can observe magnetic marks under ultraviolet (black light) irradiation. Fluorescent magnetic powder has water and oil properties.

它是以磁性氧化铁粉、工业纯铁粉、羰基铁粉等为核心,再在外面粘合一层荧光染料树脂制成。在紫外光的照射下,能发出波长为510~550nm ·为人眼接受的最敏感的鲜明的黄绿色荧光,与工件表面颜色形成很高的对比度。荧光磁粉具有很高的检测灵敏度,可见度及与工件表面的对比度都远大于非荧光磁粉,容易观察,能提高检测速度,使用范围也很广泛。

It is made of magnetic iron oxide powder, industrial pure iron powder, carbonyl iron powder, etc. as the core, and a layer of fluorescent dye resin is adhered on the outside. Under the irradiation of ultraviolet light, it can emit the most sensitive bright yellow-green fluorescence with a wavelength of 510 ~ 550 nm, which is accepted by human eyes, forming a high contrast with the surface color of the workpiece. Fluorescent magnetic powder has high detection sensitivity, visibility and contrast with workpiece surface are much higher than non-fluorescent magnetic powder, easy to observe, can improve detection speed, and has a wide range of applications.
