Description
Technical field
The present invention relates to the flaw detection on metal, compact nonmetallic material and product surface thereof, particularly a kind of cleaning foam fluid for fault detection that is used for material or workpiece surface flaw detection and preparation method thereof.
Background technology
The liquid penetrant examination method is a kind of important method in the modern nondestructive testing, originates in the World War II initial stage, is used for war industry the earliest.Become at present in the modern manufacturing industry for improve the quality of products, maintenance facilities safely, prevent a kind of important means of industry disaster accident.
This method can detect that material or surface of the work occur also in the extremely trickle fracture focus of bud.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 Materials science, fracture mechanics shows that material will be before soon rupturing, and the critical size 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, and as radiography, A type impulse ultrasound detection method can't be obtained, according to the detection sensitivity of ray and method such as ultrasonic, it can find fissured direction size can only reach 10
-1Mm.
Through for a long time development, the employed penetrant flaw detection agent of liquid penetrant test has had the product of multiple model at present in the world, and they generally are to be that preparation of raw material forms by 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 claim that generally it is a permeate agent), infilters in the microscopic checks and goes; Wipe up with the scavenging solution penetrating fluid cleaning that the next door is unnecessary then, keep the penetrating fluid in the crack as far as possible; Again image-developing liquor is applied to workpiece surface, this reagent can very fast volatilization and stay the solid film that one deck has strong adsorptive power, the penetrating fluid that stays in the microscopic checks is sucked out and is enlarged, and makes it to demonstrate place, fissured position.
Show that on solid film microscopic checks also need solve some problems: because of the size of microscopic checks very tiny, naked eyes are difficult for seeing, in order to make human eye energy direct viewing, can be by microscopical method, but can only carry out in the laboratory, the situation that meets large-scale workpiece, the enforcement of outdoor building site is then unworkable; And existing portable magnifier because of the restriction of its magnification, also can't use.And the visual field of microscope and magnifying glass is generally all very little, seeks very difficulty of a microscopic checks vestige at huge workpiece surface.The way of the solution in penetration detection is: with penetrating fluid dyeing, its dyestuff can be cherry, also can be fluorescigenic in advance.Fluorescence dye can send very strong fluorescence under special UV-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, scavenging solution and image-developing liquor at present, and wherein penetrating fluid is the fluorescent penetrant that adds the dye penetrant of orchil or add fluorescence 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 spray 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, be applicable to anhydrous, as not have electricity field construction scene preferably by contaminating impurity.
Liquid product adopts pressure aerosol jar packaged form, and the material body of its ejection has three kinds of states:
Spray---feed liquid is the minimum liquid pearl of particle, and it is floating in air to form wet fog, scatters everywhere, as perfume, mosquitocide, reodorant etc.;
Spumescence---feed liquid show bubble is attached on by on the spray object, does not fly away in air, for example tackiness agent, hairdressing mousse, spackling, leak-checking agent, dry cleaning composition etc.;
Liquid spreads shape---and feed liquid is the thicker liquid pearl of particle, can be confined to during injection not disperse in air substantially in the less jet angle, as lubricant, rust-preventive agent, only dried agent etc.
Three of penetrant flaw detection agent spray tanks (infiltration flow container, cleaning fluid tank, video picture flow container) by analysis during spraying, have only that the video picture flow container needs certain even effect when reality is used, formed film has conforming requirement on thickness.In use, infiltration flow container and these two spray tanks of cleaning fluid tank only need penetrating fluid or scavenging solution injection are come out to get final product, and there is no the requirement of vaporific quality.It is to make penetrating fluid, scavenging solution sealed storage that penetrating fluid and scavenging solution 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 that applies in the construction.
Test the effect that these spray tanks spray with a gentle test piece in sky in construction, measuring result is as follows:
(1) about 45% flaw detection agent mixes mutually with propellent, and the formation diameter is that the aerosol of 1～50 μ m disperses in air, flies away everywhere, has caused the wasting of resources;
(2) there is 55% flaw detection agent to be ejected on the detected surface of test piece approximately, propellent has been the mixture that dissolves each other in pressure-pot with the flaw detection agent, after so this mixed solution of 55% arrives workpiece surface, about 10-20 has 35% again in second along with propellent has volatilized, form aerosol and organic steam, caused the wasting of resources once more;
(3) have only about 20% to stay workpiece surface at last, finish the infiltration task that to finish.
This shows that the reagent that applies by spraying has only staying in the test piece of less than 30%, if use on the practical work piece, some is sprinkling upon outside the detected scope.
About 70% of flaw detection agent consumption flies away in air with the form of aerosol or organic steam, and these fly away thing and have following result: a part be attached to operator hair, collar, coat and on-the-spot near object correlation on; A part is along with airiness is diffused into from operation site place far away; Another part also is a part that merits attention most, has entered operator and has been 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;
Flaw detection agent consumption is increased, cause the wasting of resources.
