Abstract
A reaction type coloring and flaw detection developer using for defect detection on work piece surface, such as minute crack. Its component and weight percentage is material component wt%, glycol isomethylether 35-82, diformate methyl ester 10-40, celestite S 4-15, sedimentation silicon oxide 4-10. It is a kind of white soliquoid and changes into red when it meets reaction type coloring and flaw detection penetrant. In order to avoid the coloration of work piece, the hand of handlers, work clothes, tool, table and wall, ensure them separate with each other. It and the said reaction type coloring and flaw detection penetrant and remover use together can detect 0.5/10000mm minuteness crack.
Description
Technical field
The present invention relates to engineering flaw detection, relevant with metal works surface microscopic checks, a kind of reactive dye check developer and preparation method thereof particularly.
Background technology
Through development for a long time, the product of many kinds of models has appearred in the employed penetrant flaw detection agent of liquid penetration test, but all be in penetrating fluid, to add dyestuff to dissolve, infilter along with liquid in the microscopic checks of surface of the work to be detected and go that then that outside surface is unnecessary penetrating fluid is removed by it.Be sprayed at the surface with a kind of imaging liquid again, stay the film of one deck white after solvent evaporates, that penetrating fluid in the crack can be sucked out, spreads, it is become can observed extremely trickle crack vestige.This method has following 2 deficiencies:
1, sensitivity is subjected to certain limitation, and the dye molecule in the penetrating fluid is generally all very big, can not enter than going in the little crack of its size, and dye molecule advances not go, and also just can't show its existence;
2, pollution is difficult to clean, the dyestuff that uses in the current penetrating fluid, no matter be fluorescent dye, or orchil, they are all very strong to " dyeing capacity " of nonmetallic materials.Every operator's who is infected with hand, working cloth, instrument, worktable, ground, wall etc. are red, yellow mark everywhere, and extremely difficulty cleans up.Also do not find a kind of dyestuff now, should clean easily that its form and aspect, color depth, vividness, solubleness etc. all meet the flaw detection requirement again.
Summary of the invention
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of response type penetration defects detection developer and preparation method thereof is provided, reactive dye check developer and supporting reactive dye check penetrating fluid (separate case application) meet, the generation cerise that reacts immediately clearly shows the red vestige of defective at the bottom of the back of the body of white.
Technical scheme of the present invention is as follows:
A kind of reactive dye check developer that is used for defect detections such as surface of the work microscopic checks, its composition and percentage by weight are as follows:
Material composition wt%
The different methyl ether 35-82 of ethylene glycol
Dioctyl phthalate methyl esters 10-40
Reddish black S 4-15
Precipitated silica 4-10.
The preparation method of described reactive dye check developer comprises the following steps:
1. select for use the different methyl ether of ethylene glycol, dioctyl phthalate methyl esters, reddish black S and the precipitated silica of chemical pure or the above purity of chemical pure to make raw material;
2. select the percentage by weight of each raw material, and take by weighing each raw material in this ratio;
3. at normal temperatures, the 1/10 material cylinder of putting into hollander of powder consumption with other composition consumption mixed, pulls an oar, beating time is no less than 2 hours;
4. the slurry that 9/10 again that all the other compositions are remaining consumption is beaten in 3. going on foot with the together adds in the reactor, the airtight stirring of normal temperature, and mixing time is more than 1 hour;
5. after stirring end, promptly get the imaging liquid finished product through 100 purpose screen filtrations.
Described reactive dye check developer finished product is packed into and is done in the head tank of propellant with nitrogen, makes aerosol jar product.
Technique effect of the present invention is:
1. the present invention adds the absorption developer in solvent, is a kind of suspension of white, and when it and reactive dye check penetrating fluid (separate case application) when contacting, the reaction back generates bright-coloured redness, clearly shows the red vestige of defective at the bottom of the back of the body of white;
2. as long as the response type dye penetrant does not contact with the painted imaging liquid of response type, just can not produce color, so note the cleaning of per pass operation during operation, just can avoid unnecessary color stain, make operating personnel's hand, working cloth, work-yard etc. keep clean, also reduced environmental pollution;
Though reactive dye check developer 3. of the present invention also can be complementary with other type dye-penetrant inspection penetrating fluid, can finish the flaw detection task, can not embody the advantage of response type.
4. reactive dye check developer of the present invention and described reactive dye check penetrating fluid and the supporting use of reactive dye check cleaning liquid can detect the microscopic checks of 0.5/10000mm on the workpiece.
The composition and the number percent of described reactive dye check cleaning liquid are as follows:
Material composition wt%
Denatured alcohol 46-82
Carbonate propanediol 10-40
Hydrogenation dodecane alcohol ether 8-14;
The composition and the number percent of described reactive dye check penetrating fluid are as follows:
Material composition wt%
Hydrogenation modification ethanol 30-80
Isoamyl formate 12-45
Winestone acid benzyl ester 7-20
Antipyrine DAM 1-5.
Embodiment
Below in conjunction with specific embodiment the present invention is described in further detail.
Reactive dye check developer of the present invention is formulated by the different methyl ether of ethylene glycol, dioctyl phthalate methyl esters, reddish black S and precipitated silica.
The composition proportioning of the reactive dye check developer described in the embodiment 1 is as follows:
Ingredient w t%
