Abstract
The invention discloses a method for measuring the depth of surface open defect by injecting high-molecular polymer. The method comprises the following three steps: firstly, respectively injecting polymer monomer, an initiator, a cross-linking agent and an accelerant into a surface open defect through a portable instrument; secondly, ensuring that the monomer performs polymerization reaction, to produce space high polymer with certain elasticity and strength; thirdly, extracting the whole polymer from the outer part of the surface of the open defect through a reeling lifting measure and indirectly measuring the depth of the surface open defect. The method has the benefits that a technology for measuring the depth of surface open cracks by injecting high-molecular polymer is designed; nondestructive testing personnel can accurately measure the depth of surface open defect (such as a crack) on site when performing on-site surface open defect (such as a crack) flaw detection; the method has significance on describing the three-dimensional size of surface open defect in engineering, improving the material formula, formulating defect treatment repair schedules, and enriching the connotation of the non-destructive testing technology.
Description
Technical field
The present invention relates to brand-new injectable high molecular polymer and measure method and the device thereof of Surface-breaking defect (such as the crackle) degree of depth, for the measurement of Surface-breaking defect (such as the crackle) degree of depth.
Background technology
Conventional lossless detection method has the methods such as ultrasound examination, ray detection, Magnetic testing, Liquid penetrant testing and EDDY CURRENT. In general, the extent of injury of the surface of special equipment and the defect on nearly surface is much bigger compared with internal flaw, and in many Surface-breaking defects that Non-Destructive Testing finds, cracks with surface openings is the defect that hazardness is maximum. Therefore, in Non-Destructive Testing process, commonly used Liquid penetrant testing, Magnetic testing and EDDY CURRENT detect Surface-breaking defect.
After finding Surface-breaking defect (such as crackle), equipment ownership unit is often desirable to nondestructive testing personnel and can measure the degree of depth of Surface-breaking defect (such as crackle), because depth value belongs to unit for equipment and overhaul unit has great reference significance, first, depth value size can be used to investigate and weigh the compatibility of material and environment, in order to designs after manufacturer and produces better product; Second it is known that be easy to after depth value specify maintenance solution, and such as wide and shallow Surface-breaking defect can pass through to polish to remove, and the Surface-breaking defect that the degree of depth is bigger (such as crackle) generally requires to take to mend by replacing a damaged part and even returns factory and office's reason. But these three conventional surface lossless detection method all can not measure the degree of depth of Surface-breaking defect (such as crackle).
In reality, find that Surface-breaking defect (such as crackle) overhaul unit afterwards often cannot determine depth of defect, carry out one-time surface Non-Destructive Testing so needing to polish after some degree of depth again, then polish again that detection is until crackle is polished off completely, so cumbersome and time consuming. The situation of worst is after nondestructive testing personnel completes contracted content and leaves scene, overhaul unit finds that original macroscopic crackle has become less obvious after polishing, just think that crackle has been polished clean and stopped polishing, actually crackle is become narrow to look less obvious to naked eyes, if but carefully recognizing or take surface nondestructive detection method just just to detect it appeared that crackle yet suffers from.In this case, if equipment continues to run with, owing to cracks stress is very big, crackle can extend rapidly, it would be possible to produces the extremely serious person and property harm.
Sum it up, existing lossless detection method cannot meet people's an urgent demand for Surface-breaking defect (such as crackle) depth survey.
In order to implement country's strict demand for safety in production, solve to be difficult to measure the difficulty of its degree of depth after working site finds Surface-breaking defect (such as crackle), the invention provides a kind of injectable high molecular polymer and measure the technology of the cracks with surface openings degree of depth, synthesis of polymer material technology and Dynamic Non-Destruction Measurement are combined, take three-step approach, the longitudinal length of the degree of depth macromolecular material of Surface-breaking defect (such as crackle) is accurately represented indirectly. The portable instrument adopted is rationally distributed, and compact conformation is reasonable in design, uses easy to operate, and the lighter in weight of complete machine is easy to carry.
Summary of the invention
When it is an object of the invention to the Non-Destructive Testing being in that to realize Surface-breaking defect (such as crackle), it is possible to measure depth of defect by the technical device of the injectable high molecular polymer measurement cracks with surface openings degree of depth at the scene.
