Description
Technical field
The present invention relates to the inspection technique field, especially relate to a kind of anti-rust defect detecting liquid and preparation technology thereof.
Background technology
Flaw detection is to check whether precision parts exists the necessary check program of defectives such as crackle, scar.Its method has two kinds: a kind of is to obtain a result after by ray workpiece being scanned.The method simple and effective, but the equipment input cost is too big.Another kind is by special Magnaglo is dissolved in the oil, and workpiece is immersed wherein, and whether workpiece absorption magnetic in conduction back exists defective so that naked eyes can be distinguished.The method drops into little, most of enterprise adopts the method, but also exist obviously not enough: be carrier 1, with lightweight volatile oil such as kerosene, volatile oil has degreasing, osmosis to human body skin, very easily cause allergic, and there is very direct injury in the oil gas that evaporates to workman's respiratory tract, lung etc., and the tendency of significantly causing a disease is arranged.2, kerosene flash point has only about 60 ℃, and is careless slightly, just causes fire easily, and this type of accident is of common occurrence, and present domestic oil price is more and more higher, and the flaw detection cost is also progressively soaring.3, pollute workpiece, workpiece is difficult to be cleaned, contaminated environment, and oiliness is polluted very difficult the elimination.
Chinese patent literature discloses a kind of flame resisting fluorescent penetration flaw detection liquid and preparation method thereof [application number: 200510029684.9], the compositing formula of this defect detecting liquid is by weight percentage: the odorlessness kerosene of 30%-70%, the hydrogenation machine oil of 10%-35%, the dibasic alcohol of 10%-16%, the dibutyl phthalate of 7%-12%, the foaming agent TSHN of 2%-5% and the Baeyer fluorescein of 1%-2%, be dissolved with foaming agent TSHN in the flame resisting fluorescent penetration flaw detection liquid of the present invention, when running into higher temperature, decompose immediately, constantly emit a large amount of nitrogen, penetrating fluid is covered, isolated with airborne oxygen; Perhaps the vapor phase of combustible component is mixed in nitrogen and the fluorescent penetrant, and the shared ratio of combustible component is descended, and flash-point improves, and is nonflammable, so just can reach significant fire-retardant effect.In addition, the foaming agent TSHN that adds in fluorescent penetrant is humble poison, the minimum reagent of environmental pollution, does not also contain harmful elements such as fluorine, chlorine, sulphur, sodium, phosphorus.But this scheme still can not solve the technical matters of above-mentioned existence fully.
Summary of the invention
The objective of the invention is at the problems referred to above, a kind of infiltration, good dispersion are provided, show that the magnetic trace is clear, highly sensitive, save a large amount of oils, avoid producing and pollute, reduce the anti-rust defect detecting liquid of flaw detection cost; Solved the existing poor effect of prior art, the technical matters that use cost is high.
Another object of the present invention is at the problems referred to above, a kind of not flammable, nothing volatilization is provided, effectively ensure production safety, avoid the allergic and respiratory tract of workman, safeguard employee's physical and mental health, significant anti-corrosion defencive function, the anti-rust defect detecting liquid of rust-proof life more than a week under mal-condition; It is relatively poor to have solved the existing in prior technology security, very easily causes allergicly, and there is very direct injury in the oil gas that evaporates to workman's respiratory tract, lung etc., and the technical matters of the tendency of significantly causing a disease etc. being arranged.
For achieving the above object, the present invention has adopted following technical proposal: this anti-rust defect detecting liquid is characterized in that component and weight percentage thereof that this anti-rust defect detecting liquid comprises are respectively: carboxylic esters 0.8-5.0%; Polyvalent alcohol 2.0-20.0%; Non-ferrous metal antiseptic 0.2-1.0%; Ionic surfactant 1.0-10.0%; Alkyl phenol ring chlorine polymkeric substance 1.0-10.0%; Spreading agent 4.0-30.0%; Magnetic adsorbent 1.0-10.0%; Developer 3.0-10.0%; Foam inhibitor 0.1-1.0%; Water is surplus.
