Description
Technical field
The present invention relates to a kind of shear wave couplant, specifically a kind of station boiler steel pipe inner wall oxide film high frequency ultrasound wave measurement shear wave couplant and preparation method thereof.
Background technology
Ultrasonic detecting equipment adopts up-to-date high-performance, low-power microprocessor technology, based on Ultrasonic Pulse-Echo principle, can measure the thickness of metal and other multiple material, can also measure the velocity of sound of material.When the ultrasonic pulse launched when popping one's head in arrives material interface by testee, pulse is reflected back toward the thickness that the time of propagating in the material by accurately measuring ultrasound wave of popping one's head in determines measured material.Ultrasonic detecting equipment can carry out thickness measure to pipeline various in production equipment and pressure vessel, monitor they in use corroded after thinning degree, also can do accurately to measure to various sheet material and various processing parts.In prior art, ultrasound examination is divided into compressional wave and shear wave, and compressional wave refers to that the sound wave that the direction of vibration of sound bearing medium particle is consistent with sound direction of wave travel, shear wave then refer to the perpendicular sound wave in the particle vibration direction of sound bearing medium and Acoustic Wave Propagation direction; As a rule, in ultrasound examination, the normal probe that adopts carries out compressional wave detection more, adopts angle probe to carry out shear wave detection.As everyone knows, in ultrasound examination, the compressional wave that shear wave detects ratio detects, shear wave is under same frequency about the short half of wavelength, more easily produce surface disturbance, as beginning ripple accounts for wide increasing, clutter increases, therefore when couplant effect is roughly the same, need the surface smoothness of an examined workpiece grade higher than compressional wave.Considering workpiece shapes, section thickness and in the situation such as the bearing of trend that may produce defect, because wavelength is shorter, the surperficial acoustical energy losses therefore caused by surface roughness affect is larger than compressional wave.This just requires that testee end face flatness is higher, more extensive in order to make ultrasonic transverse wave detection method apply, and also just requires that shear wave couplant can be applicable to the surface of different surface roughness.
Couplant is a kind of water soluble polymer colloid, and it is used to get rid of the air between probe and testee, makes ultrasonic wave energy effectively penetrate measured object and reaches effective testing goal.Couplant is divided into two kinds, is respectively coupling agent for medical use and industrial couplant.Coupling agent for medical use is a kind of curable product be made up of aqueous high molecular gel of new generation.Industry couplant is used to get rid of the air between probe and testee, ultrasonic wave energy is penetrated effectively product that workpiece reaches testing goal.At present, in commercial Application, in order to reduce production cost, general industrial couplant is mainly with machine oil, transformer oil, railway grease, glycerine, water glass (sodium silicate Na
2siO
3) or industrial glue, chemical paste, or the special couplant of commercial Ultrasonic Detection, mostly be liquid; Solid-state is less, such as aluminium foil.But the coupling tightness degree of solid-state couplant under low-stress is very poor, and the scope of application is too small; And when adopting the couplant of industrial glue, chemical paste, these liquid state of machine oil, due to viscosity reason, although can pass through compressional wave, not by most of high-frequency shear wave, it is only applicable to compressional wave and detects.The more important thing is, because compressional wave detects less than the scope of application of shear wave detection, therefore shear wave detects the defect being more conducive to finding object under test than compressional wave detection, is the development and study direction of ultrasound examination.But up to the present, the limitation (namely shear wave testing requirement testee end face flatness is higher, and when namely detecting, the viscosity of shear wave couplant is enough large) detected due to shear wave is domestic not to be had producer and can produce and a kind ofly can reach the above-mentioned shear wave couplant more easily carrying out shear wave detection.
