Abstract
The present invention relates to dye-penetrant inspection technical fields, disclose a kind of safety and environmental protection colorant, are that 45%~80% ethylene glycol, 15%~30% ethyl alcohol, 3%~15% sorbierite and 2%~10% rhodamine form by percent by volume.Colorant of the present invention is free of harmful components, and safety and environmental protection is readily transported carrying, can easily remove the extra colorant of workpiece surface using washing, detect a flaw at low cost.
Description
Technical field
The present invention relates to dye-penetrant inspection technical fields, and in particular to a kind of safety and environmental protection colorant.
Background technique
Dye-penetrant inspection is five kinds of conventional lossless detection method (Liquid penetrant testing, Magnetic testing, ray detection, ultrasonic waves
One of detection, EDDY CURRENT), to detect the Surface-breaking defect of non-porous base material.With other lossless detection methods
Equally, dye-penetrant inspection is also to have premised on not destroying checked object to various engineering material, components and product
The inspection of effect, so as to evaluating their integrality, continuity and security reliability.Penetrant inspection is to realize that quality controls important
Means are indispensable component parts in product manufacturing and use and maintenance.
The basic principle of dye-penetrant inspection is capillarity principle.Dye check agent, that is, colorant is applied to work
Part surface, due to capillarity, colorant, which penetrates into all kinds of surfaces, to be had in the tiny flaw of opening, and surface is removed after infiltration
Extra colorant applies imaging agent, and the colorant in defect is bled back on workpiece surface again, and it is aobvious to form the defect being exaggerated
Show, observed under white light, fault location can take on a red color display, visually can be detected out the state and distribution of defect.
Harmful components are usually contained in existing colorant, are easy to cause damages to the physical and mental health of ecological environment and people, and
Also contain flammable material, risk is high, does not allow to carry to vehicle, ship or aircraft, causes transport inconvenient.
Summary of the invention
The purpose of the invention is to overcome the deficiencies of the prior art and provide a kind of safety and environmental protection colorant, the colorant
Without harmful components, safety and environmental protection is readily transported carrying, can easily remove the extra colorant of workpiece surface using washing,
It detects a flaw at low cost.
To achieve the goals above, the present invention provides a kind of safety and environmental protection colorant, by percent by volume be 45%~
80% ethylene glycol, 15%~30% ethyl alcohol, 3%~15% sorbierite and 2%~10% rhodamine composition.
Preferably, the percent by volume of the ethylene glycol is 70%, and the percent by volume of the ethyl alcohol is 20%, the mountain
The percent by volume of pears alcohol is 5%, and the percent by volume of the rhodamine is 5%.
Colorant of the present invention is free of harmful components, and safety and environmental protection is readily transported carrying, can easily remove work using washing
The colorant of part excess surface is detected a flaw at low cost.
Specific embodiment
The endpoint of disclosed range and any value are not limited to the accurate range or value herein, these ranges or
Value should be understood as comprising the value close to these ranges or value.For numberical range, between the endpoint value of each range, respectively
It can be combined with each other between the endpoint value of a range and individual point value, and individually between point value and obtain one or more
New numberical range, these numberical ranges should be considered as specific open herein.
Embodiment 1
A kind of safety and environmental protection colorant, by percent by volume be 45%~80% ethylene glycol, 15%~30% ethyl alcohol,
3%~15% sorbierite and 2%~10% rhodamine composition.Wherein, ethyl alcohol and sorbierite are penetrating solvent, and ethylene glycol is
Surfactant, rhodamine are fluorochrome.
In use, colorant is applied to workpiece surface, due to capillarity, penetrating colorants have opening to all kinds of surfaces
Tiny flaw in, excess surface colorant is removed after infiltration, then applies imaging agent, the colorant in defect is bled back again
Onto workpiece surface, forms the defect being exaggerated and show, issue fluorescence under ultraviolet light, can detecte out Surface Flaw
It is formed and is distributed.
Colorant of the present invention is free of harmful components, and safety and environmental protection is readily transported carrying, can easily remove work using washing
The colorant of part excess surface is detected a flaw at low cost.
Embodiment 2
A kind of safety and environmental protection colorant, is made of ethylene glycol, ethyl alcohol, sorbierite and rhodamine, the volume of the ethylene glycol
Percentage is 70%, and the percent by volume of the ethyl alcohol is 20%, and the percent by volume of the sorbierite is 5%, the Luo Dan
Bright percent by volume is 5%.
The preferred embodiment of the present invention has been described above in detail, and still, the present invention is not limited thereto.In skill of the invention
In art conception range, can with various simple variants of the technical solution of the present invention are made, including each technical characteristic with it is any its
Its suitable method is combined, and it should also be regarded as the disclosure of the present invention for these simple variants and combination, is belonged to
Protection scope of the present invention.
