熒光磁粉

Fluorescent magnetic powder

熒光磁粉 這是一種在紫外線(黑光) 照射下進行磁痕觀察的磁粉。熒光磁粉有水性和油性兩種。

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.

它是以磁性氧化鐵粉、工業(yè)純鐵粉、羰基鐵粉等為核心，再在外面粘合一層熒光染料樹脂制成。在紫外光的照射下，能發(fā)出波長為510~550nm ·為人眼接受的最敏感的鮮明的黃綠色熒光，與工件表面顏色形成很高的對比度。熒光磁粉具有很高的檢測靈敏度，可見度及與工件表面的對比度都遠大于非熒光磁粉，容易觀察，能提高檢測速度，使用范圍也很廣泛。

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.
