Description

Foam type dye check penetration liquid and preparation method thereof
Technical field
The present invention relates to the flaw detection on metal, compact nonmetallic material and product surface thereof, particularly a kind of foam type dye check penetration liquid that is used for material or surface of the work flaw detection and preparation method thereof.
Background technology
The liquid penetrant examination method is a kind of important method in the modern Non-Destructive Testing, originates in the World War II initial stage, is to be used for war industry the earliest.Become at present in the modern manufacturing industry for improve the quality of products, service equipment safely, prevent a kind of important means of industry disaster accident.
This method can detect the extremely trickle fracture focus that is in the embryonic stage of material or surface of the work appearance.The rupture failure accident that promptly will take place for various machineries such as boats and ships, aircraft, bridge, boilers has the effect of forecast.The result of study of material science, fracturing mechanics shows that material will be before soon rupturing, and the critical dimension of microscopic checks is generally 10 -4The order of magnitude of mm, as surpassing this numerical value, the intensity of the anti-stress of material will sharply descend, and rupture because of supporting moment.The detection sensitivity of liquid penetrant examination can detect 10 at present -5The microscopic checks of the mm order of magnitude that is to say, the liquid penetrant examination method can be sent urgent early warning before parts rupture.This is other lossless detection methods, as film radiography, A type impulse ultrasound detection method institute can not and, according to the detection sensitivity of ray and method such as ultrasonic, its direction size that can find the crack can only reach 10 -1Mm.
Through for a long time development, the employed penetrant flaw detection agent of liquid penetration test has in the world had the product of multiple model at present, and they generally are to be that raw material is formulated with some organic solvents, and application performance has his own strong points.But all there are some common shortcomings in they: volatile, easy firing, certain toxicity is arranged and environment is caused certain pollution because of volatilization.Also the someone works out some hypotoxicities, oligosaprobic prescription at present, but also fails thoroughly to solve penetrant flaw detection agent these shortcomings in construction so far.
The ultimate principle that infiltration detects is with a kind of material (overwhelming majority is a liquid, and also having a spot of is gas and solid, so generally be called bleeding agent), infilters in the microscopic checks and goes; Wipe up with the cleaning fluid bleeding agent cleaning that the next door is unnecessary then, keep the bleeding agent in the crack as far as possible; Again imaging liquid is applied to surface of the work, the very fast volatilization of this reagent and stay the solid film that one deck has strong absorption affinity sucks out the bleeding agent that stays in the microscopic checks and is enlarged, and makes it to demonstrate the place, position in crack.
Show that on solid film microscopic checks need solve some problems: because of the size of microscopic checks very tiny, naked eyes are difficult for seeing, in order to make naked eyes energy Direct observation, can be by microscopical method, but can only this method can only carry out, meet on large-scale workpiece, the outdoor building site then unworkable in the laboratory; And existing portable magnifier because of the restriction of its enlargement factor, also can't use.And the visual field of microscope and magnifier is generally all very little, seek very difficulty of a microscopic checks vestige at huge surface of the work, the way of the solution in penetration detection is: with penetrating fluid dyeing, its dyestuff can be cherry, also can be fluorescigenic in advance.Fluorescent dye can send very strong fluorescence under special ultraviolet light, also can send dazzling fluorescence under the common white rayed.With the most use on the current engineering is that penetrating fluid is dyed redness, and it and snow-white video picture film form very high contrast background, are easy to observe extremely trickle crack vestige.
Summary is got up, and penetrant flaw detection agent is made up of penetrating fluid, cleaning fluid and imaging liquid at present, and wherein penetrating fluid is the fluorescent penetrant that adds the dye penetrant of orchil or add fluorescent dye.
In current engineering is used, in order to be applicable to construction sites such as field, high-altitude, penetrant flaw detection agent generally all is made into the atomisation pressure jar of 500ml, this preserving type can fine sealing be preserved the flaw detection agent, make that it is non-volatile, do not gone bad, can store for a long time and be convenient for carrying by contaminating impurity, be applicable to anhydrous, as not have electricity field construction scene preferably, quite being subjected in the industry, personnel welcome.By analysis when reality is used, three aerosol cans of penetrant flaw detection agent (infiltration flow container, cleaning fluid tank, video picture flow container) have only the video picture flow container when spraying, need certain even effect, formed film has consistent requirement on thickness.As for infiltration flow container and these two aerosol cans of cleaning fluid tank, in use, only need penetrating fluid or cleaning fluid injection are come out to get final product, there is no the requirement of vaporific quality.It is to make penetrating fluid and cleaning fluid sealed storage that penetrating fluid and cleaning fluid are taked canned advantage, non-volatile, not contaminated rotten; Other three kinds of defect detecting liquids are all made onesize jar, pack easily, be easy to carry and store, and spray the high efficiency of using in the construction.
Test the effect that these aerosol cans spray with a gentle test piece in sky in construction, measurement result is as follows:
(1) about 45% flaw detection agent and propellant mix mutually, and the gasoloid that forms diameter and be 1 μ m~50 μ m disperses and flies away everywhere in air, has caused the wasting of resources;
(2) there is 55% flaw detection agent to be ejected on the surface of detected test piece approximately, propellant has been the mixture that dissolves each other in head tank with the flaw detection agent, after so this mixed liquor of 55% arrives surface of the work, about 10-20 in second, there is the flaw detection agent about 35% to volatilize again with propellant, form gasoloid and organic steam, caused the wasting of resources once more;
(3) have only about 20% to stay surface of the work at last, finish the infiltration task.
This shows that the reagent that applies by spraying has only the flaw detection agent of less than 30% to stay in the test piece, if use on the practical work piece, some is sprinkling upon outside the detected scope in the middle of this.
About 70% of flaw detection agent consumption flies away in air with the form of gasoloid or organic steam, and these fly away thing can cause following result: a part be attached to operating personnel hair, collar, coat and on-the-spot near object correlation on; A part is along with circulation of air is diffused into from operation site place far away; Another part also is a part that merits attention most, enters operating personnel and is in the scene or near other staff's lung by respiratory tract, sticks in vivo, deposits and be absorbed.This shows the existence of flaw detection agent steam and aerosol, following shortcoming arranged:
1. suck the human lung, stick skin, directly be detrimental to health;
2. aggregate concentration acquires a certain degree in air, very easily causes the generation of fire;
3. no matter be indoor, still certain environmental pollution all can be caused in the field;
4. increase the consumption of flaw detection agent, cause the wasting of resources.
