Abstract
A kind of penetrating fluid of flaw detection that is used for Non-Destructive Testing, it is to add illuminating colour and fluorescent dye simultaneously, and (as peregal A-20) is formulated with a certain proportion of kerosene, dibutyl phthalate, emulsifying agent.This defect detecting liquid can use down at daylight (or white light), also can use under the medium ultraviolet light irradiation of darkroom, and promptly a kind of penetrating fluid of flaw detection has both dye penetrant inspection and two kinds of functions of fluorescent penetrating inspection simultaneously.The characteristics of this defect detecting liquid are the flaw detection sensitivity height; Can find flaws 0.5 μ width; And unnecessary defect detecting liquid can more easily be cleaned.In addition, this penetrating fluid seepage force is strong, and time of penetration is short, and favorable reproducibility is to operator safety, pollution-free.
Description
The invention belongs to the penetrating inspection material that is used in the Non-Destructive Testing.
Richard in 1973, L.P. (1) once commented the effect and the principle of penetration flaw detection liquid.And U.S.4, patents such as 186,304 and U.S.3,912,653 have been reported the prescription and the performance of fluorescence flaw detection infiltration solution and dye check penetrating fluid.Two class defect detecting liquids respectively have its relative merits:
In actual detected, need above-mentioned two kinds of penetrating fluid of flaw detection to be used in combination sometimes, could finally judge alligatoring, avoid omission.Therefore, the objective of the invention is to formulate out the dual-purpose penetrating fluid of flaw detection of a kind of painted fluorescence.It can be used down at daylight (or white light), also can use under the medium ultraviolet light irradiation of darkroom, promptly a kind of penetrating fluid of flaw detection has both dye penetrant inspection and two kinds of functions of fluorescent penetrating inspection simultaneously.
Key of the present invention is to select for use painted and fluorescent dye.The composition of this penetrating fluid of flaw detection comprises: hydrocarbons, ester class, emulsifying agent and the dyestuff that meets above-mentioned purpose.Its flaw detection operating procedure comprises and workpiece is given steps such as cleaning, infiltration, cleaning, developing and inspection.
The illuminating colour that this penetrating fluid uses as Sudan IV, phloxine, propyl red, Congo red, methyl violet, oil red, candle is red, oil is blue, Oil Yellow, rhodamine etc.The fluorescent dye that this penetrating fluid uses is perylene class, naphthoyl amine, imidazoles, cumarin etc.
Use this penetrating fluid can be at the following developing of daylight (or white light), also can be under uviol lamp (darkroom) developing.In addition, can also receive following technique effect:
1. flaw detection sensitivity height.It is qualified that standard flaw detection test specimen is detected.Crackle is high-visible.Can show 0.5 μ flaws.
2. seepage force is strong.Enter in the Surface Flaw easily.
3. bright in colour.
4. required time of penetration is short, generally in 10 minutes.
5. favorable reproducibility.
6. to the workpiece non-corrosiveness.
7. clean easily, water or clean-out system clean all can.
8. environment is not polluted,, nothing corrosion non-stimulated to skin washes from skin easily.
Embodiment:
Earlier that workpiece is fully dry with the clear wash clean And of clean-out system, then defect detecting liquid is coated on working surface, or workpiece immersed in the defect detecting liquid, or defect detecting liquid injected in the sprayer spray, make defect detecting liquid infiltrate workpiece, defect, water is removed unnecessary penetrating fluid again, after to be dried, apply photographic developer (as magnesium oxide, monox or alumina powder), so that surface of the work is made in the absorption of the penetrating fluid in the defective, then the flaw detection usefulness uviol lamp under or under daylight, observe, then can see the image of defective.The prescription of used defect detecting liquid is as follows:
Material weight percentage
Illuminating colour cumarin 7%
Fluorescent dye fluorescein 6%
Kerosene 7%
Dibutyl phthalate 65%
Peregal A20 15%

Claims (3)
1, a kind of penetrating fluid of flaw detection that is used for Non-Destructive Testing is characterized in that it is with illuminating colour and fluorescent dye, and it is formulated to add kerosene, dibutyl phthalate, emulsifying agent organic solvents such as (as peregal A-20).
2, described according to claim 1, illuminating colour in the dual-purpose penetrating fluid of flaw detection of a this novel painted fluorescence is Sudan IV, phloxine, propyl red, Congo red, methyl violet, oil red, candle is red, oil is blue, Oil Yellow, rhodamine etc., and its fluorescent dye is flower class, naphthoyl amine, imidazoles, cumarin etc.
3, according in the dual-purpose penetrating fluid of flaw detection of the described painted fluorescence of claim 1, the percent by weight of its illuminating colour (as rhodamine), fluorescent dye (as cumarin) and kerosene, dibutyl phthalate and emulsifying agent (peregal A-20) is respectively 7%, 6%, 7%, 65%, 15%.
