Abstract
Permeating crack-detection coated film strippable developer is a kind of Non-Destructive Testing material, it is characterized in that the chemical mixture colloid by nitrocellulose, acetate fiber and solvent composition thereof.
Subsequent handling in permeation flaw detection or magnetic powder inspection, make it on the detection surface of the desire record that is verified workpiece, to form uniform film the form of the defective that this rete can write down dye penetrant inspection, fluorescent penetrating inspection and magnetic powder inspection without distortion and detected with the spraying or the method for brushing.Its sensitivity and resolution are not less than sensitivity and the resolution that above-mentioned method of detection reaches separately, and are not subjected to the influence in material, illumination condition and flaw detection place.
Use adhesive tape to strengthen the method for rete, rete is successfully separated with workpiece, for flaw detection man analysis defects property or as technology files data long preservation.
Description
The present invention relates to a kind of Non-Destructive Testing material and using method thereof, especially for the permeating crack-detection coated film strippable developer and the using method thereof of Non-Destructive Testing.
From dye penetrant inspection, fluorescent penetrating inspection and magnetic powder inspection have been widely used in as the method for Non-Destructive Testing since the inspection method of surface imperfection of various materials and all kinds of mechanical component, also do not have a kind of reliable method and material can be without distortion, the defective form found of record for good and all.Though photographic process can be used to write down the defective that dyeing inspection is found, but be subjected to the restriction and the influence of inspected object position, sometimes even can't implement, and with the ratio difference or the camera angles difference of amplifying, dwindling, the capital makes the defective distortion of record, the defective found of fluoroscopy particularly is because of it can only just can manifest under uviol lamp, so almost can't write down the defective of being found with photographic process.
But the purpose of this invention is to provide a kind of not only film forming but also peelable, can show permeating crack-detection coated film strippable developer and using method thereof easily and accurately with the various material surface defective of permanent recording form.
The object of the present invention is achieved like this: by the mass/volume ratio, with nitrocellulose (0.5-20) %, acetate fiber (0.5-10%), and the fully mixing at normal temperatures and pressures of surplus acetone promptly obtain the permeating crack-detection coated film strippable developer that the present invention will provide.When utilizing this developer to carry out detection record, at first the subsequent handling in Non-Destructive Testing is coated with this developer (preferably spraying) and is subjected to inspection surperficial to the desire record of tested object, make it to form thin film, rely on film the suction-operated of colorant, fluorescer or magnetic to be noted the defective form that is manifested, and then paste on the rete with adhesive tape (masking tape or glue are moulded band) and gain in strength, just adhesive tape and rete can be stripped down simultaneously, for the usefulness of on-the site analysis and permanent preservation.
Permeating crack-detection coated film strippable developer of the present invention confirms to have following characteristics through overtesting:
1, using permeating crack-detection coated film strippable developer of the present invention to reach with what it matched strengthens rete and adheres to the method for peeling off with adhesive tape, the form that both can manifest the defective of dye penetrant inspection, fluorescent penetrating inspection and magnetic powder inspection discovery without distortion, rete is separated with tested object, preserve as technology files.
2, the development sensitivity of rete of the present invention and resolution are not less than sensitivity and the resolution that dye penetrant inspection, fluorescent penetrating inspection and magnetic powder inspection itself reached.
3, use permeating crack-detection coated film strippable developer of the present invention not to be subjected to the influence of tested object material, be not subjected to the influence of tested object position and illumination condition, all can obtain same effect.And detect then and there, overlay film can be seen the result then and there then and there.
Claims (3)
1, a kind of permeating crack-detection coated film strippable developer is characterized in that all the other are formed by acetone by (0.5-20) % nitrocellulose, (0.5-10) % acetate fiber.
2, a kind of using method of permeating crack-detection coated film strippable developer is characterized in that:
A, permeating crack-detection coated film strippable developer is coated onto being examined on the surface of tested object, makes it to form rete;
B, paste on the rete and with adhesive tape and to peel off with rete.
3, the method for use permeating crack-detection coated film strippable developer according to claim 2 is characterized in that: step a sprays to developer to be examined on the surface.
