Abstract

The invention discloses a fluorescent oil-based magnetic suspension liquid. The fluorescent oil-based magnetic suspension liquid consists of 45-65wt% of solvent oil, 25-40wt% of 10# machine oil, 4-10wt% of emulsifier, 0.1-0.25wt% of fluorescent magnetic powder and 2-6wt% of defoamer. The oil-based magnetic suspension liquid prepared from a regulator provided by the invention meets the technical requirements of the non-destructive testing technology on the magnetic suspension liquid related to magnetic powder inspection completely: 1, the workpiece after being subjected to flaw detection is free from rusting; 2, the fluorescent magnetic powder in a carrier liquid is excellent in suspension property; and 3, massive foam which affects the flaw detection effect is not formed during spray due to the using of the defoamer.

Description

technical field

[0001] The invention relates to a fluorescent oil-based magnetic suspension.

[0002] Background technique

[0003] When the present invention is applied to fluorescent magnetic particle flaw detection, the fluorescent magnetic suspension accumulated at defect parts can display yellow-green fluorescent display through the excitation of ultraviolet light, and inspectors can directly observe. The fluorescent magnetic particle flaw detection used in the past required inspectors to use many kinds of additives on site, and then weighed and proportioned, which was very troublesome for the inspectors, and the concentration and suspension of the proportion were difficult to control, and often failed to obtain foreign supervisory inspections. staff approval.

[0004] Contents of the invention

[0005] The purpose of the present invention is to provide a fluorescent oil-based magnetic suspension that is more convenient to use.

[0006] In order to solve the above...
