Description
Technical field
The present invention relates to a kind of industrial couplant and preparation method thereof, specifically a kind of boiler tube inner wall oxide film ultrasonic measurement couplant and preparation method thereof.
Background technology
Couplant is a kind of water soluble polymer colloid, and it is used to get rid of the air between the probe of ultrasonic detecting equipment and testee, makes ultrasonic wave energy effectively penetrate object to reach 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.Due in the daily indagation of people, often need to widely apply ultrasonic inspection, therefore the application of couplant in medical science widely.The pH value of coupling agent for medical use is neutral, harmless to human non-toxic, and not easily dry, not easily become sour, ultrasonoscopy is clear, and toughness is suitable for, and without greasy, probe is easy to slide, wettable skin, and eliminate skin surface air, greasy property is good, is easy to launch; , not damaged corrosion-free to ultrasonic probe, therefore production cost is very expensive.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.
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.The more important thing is, in existing ultrasonic detection technology, because compressional wave refers to the sound wave that the direction of vibration of sound bearing medium particle is consistent with sound direction of wave travel, shear wave then refers to the perpendicular sound wave in the particle vibration direction of sound bearing medium and Acoustic Wave Propagation direction, therefore the normal angle probe that adopts carries out shear wave detection, adopts normal probe to carry out compressional wave detection.As everyone knows, in ultrasound examination, the compressional wave that shear wave detects ratio detects, and when wavelength is identical, ultrasonic detecting equipment produces horizontal wave frequency and is at half than compressional wave, and production cost is lower; But because shear wave about the short half of wavelength, more easily produces surface disturbance under same frequency, 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, namely requires that shear wave couplant can be applicable to the surface of different surface roughness.It is reported, ultrasound examination of today or thickness-measuring equipment are usually configured with normal probe and angle probe simultaneously, but because the requirement of shear wave detection method to shear wave couplant is higher, the manufacturer of Ultrasonic Detection or defect-detecting equipment also cannot produce the industrial couplant that can be applicable to different surface roughness body surface, often advises that client uses the liquid such as liquid detergent, hand cleanser as couplant.But in the metal detection process of specialty, this class I liquid I can not reach detection object; And although ultrasound examination or thickness-measuring equipment are equipped with horizontal stroke, compressional wave detection probe on the market, when determinand surface is smooth not, needs the industrial couplant being specially adapted for shear wave of purchasing price costliness, cause testing cost high; Or change the detection of employing compressional wave into, cause testing result inaccurate.Therefore the limitation of existing industrial couplant limits the application of ultrasonic detecting equipment.
As mentioned above, to so far, domestic not a kind of industrial couplant being widely used in high-frequency shear wave, therefore need one and can be applicable to ultrasound wave compressional wave and detect, also the industrial couplant that ultrasonic transverse wave detects can be applicable to, to improve the detection level of Chinese ultrasound examination.
