Description
Technical Field
The invention relates to a fluorescent cleaning agent, a preparation method thereof and a method for detecting parts by using the fluorescent cleaning agent.
Background
The penetrant inspection process is well known in the art and is intended to detect very small surface discontinuities and subsurface defects with surface openings in test bodies. The test body or part may be made of metal, ceramic or other material. The known method comprises a non-destructive testing penetration test procedure, a usual procedure consisting, as a first step, of immersing the test body in a penetration defect tracing liquid in which a fluorescent dye or a non-fluorescent visible dye is dissolved. Commonly used penetrant inspection tracers have been formulated as an oily liquid vehicle in which the dye is dissolved.
After soaking the test bodies in the penetrant for a suitable residence time, the test bodies are removed from the liquid and then subjected to draining, emulsifying and washing operations to remove any penetrating liquid adhering to their surfaces. However, a small retentate of permeate is still present in any surface discontinuity or subsurface defect having surface openings, even if very small. If the permeate used contains dissolved fluorescent dyes, the capture can be made visible by exposure to ultraviolet radiation. On the other hand, if the permeate contains dissolved non-fluorescent visible dyes, the capture can be seen under normal light.
The fluorescent penetrant consists essentially of an oily vehicle containing a suitable concentration of a detergent material sufficient to emulsify the oily mixture in water. The presence of detergent material penetration formulations results in an "adsorption" effect, which is difficult to clean and affects the detection effect.

The degreasing agent can quickly and efficiently remove oil stains at normal temperature, can replace organic solvents such as benzene, carbon tetrachloride and trichloroethylene to remove oil on the surfaces of cracks in fluorescent flaw detection, has small corrosivity to metal equipment and good antirust effect, enables the fluorescent flaw detection sensitivity to be higher, reduces pollution harmfulness, saves energy, protects environment, is safe, has high cleaning cost, and has good industrial practical value.
In order to solve the above technical problem, the present invention provides a method for detecting a part, including:
step (1), cleaning the surface of a workpiece to be detected;
step (2), spraying a fluorescent penetrant on the surface of the dried workpiece to be detected, waiting for 5-10 minutes to allow the fluorescent penetrant to enter and be embedded in cracks on the surface of the workpiece to be detected,
a step (3) of applying an emulsifier to the component to emulsify excess osmotic agent;
step (4), when the fluorescent penetrant is retained at the crack and the surface of the workpiece to be detected is still wet, the fluorescent cleaning agent prepared by the method is used for washing the workpiece to be detected so as to remove the emulsifier and the emulsified penetrant;
step (5), coating dry hydrophobic developer particles on the surface of the workpiece to be detected, waiting for 3-5 minutes, and removing redundant developer;
and (6) checking the fluorescent penetrant of the workpiece to be detected to seep out of the crack and enter the particles.
Further, water droplets remaining after washing are removed by the gas stream.
Further, the hydrophobic developer includes silica aerogel.
Further, the hydrophobic developer consists of calcium carbonate.
Further, excess hydrophobic developer particles were removed by air spraying.
Further, the hydrophobic developer particles have an average particle size of no more than 1 micron.
The method for detecting the parts adopts the fluorescent cleaning agent provided by the invention to wash the workpiece to be detected so as to remove the emulsifier and the emulsified penetrant; and then the workpiece to be detected is placed under ultraviolet light, and no fluorescence display is found, so that the fluorescent cleaning agent provided by the invention can completely remove residual liquid of a fluorescent penetrant, effectively avoids detection omission, enables the fluorescent flaw detection sensitivity to be higher, reduces pollution harmfulness, and has good industrial practical value.

Example 5
A method of inspecting a part, comprising:
cleaning the surface of a workpiece to be detected;
step (2) spraying a fluorescent penetrant on the surface of the dried workpiece to be detected for 5-10 minutes to allow the fluorescent penetrant to enter and be embedded in cracks on the surface of the workpiece to be detected,
step (3) applying an emulsifier to the part to emulsify excess osmotic agent;
step (4) when the fluorescent penetrant is retained at the crack and the surface of the workpiece to be detected is still wet, washing the workpiece to be detected by using the fluorescent cleaning agent prepared in the embodiment 4 to remove the emulsifier and the emulsified penetrant;
step (5) coating dry hydrophobic developer particles on the surface of the workpiece to be detected, waiting for 3-5 minutes, and removing redundant developer;
step (6), the workpiece to be detected is checked, and a fluorescent penetrant seeps out of the crack and enters the particles; it can be seen that the cracks are fully revealed. The fluorescent cleaning agent prepared by the invention can completely remove redundant penetrating fluid, reduce the influence of background, improve the detection sensitivity, and has no influence on fluorescence luminescence and detection results.
In example 5, the water droplets remaining after the washing in step (4) were removed by a gas stream.
The hydrophobic developer consists of calcium carbonate.
Excess hydrophobic developer particles were removed by air spraying.
The hydrophobic developer particles have an average particle size of no more than 1 micron.
Example 6
Examination of the cleaning performance of penetrants with the fluorescent cleaning agent prepared in example 5:
in the embodiment 5, when the fluorescent penetrant is retained at the crack and the surface of the workpiece to be detected is still wet in the step (4), the workpiece to be detected is washed by the fluorescent cleaning agent prepared in the embodiment 3 to remove the emulsifier and the emulsified penetrant; and then, the workpiece to be detected is placed under ultraviolet light, and no fluorescence display is found, which shows that the fluorescent cleaning agent provided by the invention can completely remove the residual liquid of the fluorescent penetrant.
Comparative example 1
A method of inspecting a part, comprising:
cleaning the surface of a workpiece to be detected;
step (2) spraying a fluorescent penetrant on the surface of the dried workpiece to be detected for 5-10 minutes to allow the fluorescent penetrant to enter and be embedded in cracks on the surface of the workpiece to be detected,
step (3) applying an emulsifier to the part to emulsify excess osmotic agent;
step (4) when the fluorescent penetrant is retained at the crack and the surface of the workpiece to be detected is still wet, washing the workpiece to be detected with water to remove the emulsifier and the emulsified penetrant; then, the fluorescent display is carried out under an ultraviolet lamp, and the residue of the fluorescent penetrant can be seen, so that the fluorescent penetrant is difficult to clean completely only by water.
In conclusion, the fluorescent cleaning agent provided by the invention is compounded by a plurality of surfactants, and can increase the stability, improve the decontamination capability, the defoaming property and the rinsing performance through the coordination effect. The degreasing agent can quickly and efficiently remove oil stains at normal temperature, can replace organic solvents such as benzene, carbon tetrachloride and trichloroethylene to remove oil on the surfaces of cracks in fluorescent flaw detection, has small corrosivity to metal equipment and good antirust effect, enables the fluorescent flaw detection sensitivity to be higher, reduces pollution harmfulness, saves energy, protects environment, is safe, has high cleaning cost, and has good industrial practical value.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
