Description
Technical field
The present invention relates to a kind of couplant, specifically a kind of couplant and preparation method thereof.
Background technology
Couplant is used to get rid of the air between the probe of ultrasonic measurement instrument and testee, makes ultrasonic wave energy effectively penetrate workpiece and reaches testing goal.If select kind or using method improper, will cause error or coupling mark glimmer, cannot measure.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.Due in the daily indagation of people, often need to widely apply ultrasound investigation, therefore the application of couplant in medical science widely.State Food and Drug Administration of China ratifies and issues the pharmaceuticals industry standard YY0299-2008 implementing and be entitled as " medical ultrasonic coupling agent ", in this standard, product composition is required to include for the technology (safety and effectiveness) of couplant, (under short-time contact condition, product is to skin no cytotoxicity for biocompatibility, without sensitization, non-stimulated), performance (the velocity of sound, acoustic characteristic impedance, acoustic attenuation and pH value), outward appearance (colourless or light-coloured transparent gel, without or only have a small amount of bubble, without insoluble foreign body), (there is not layering in 1 year in product to stability, go mouldy or abnormal flavour).The pH value of existing 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.As the medical ultrasonic coupling agent that Chinese invention patent CN102107012B provides, in weight percent hundred containing aminopolysaccharide 0.1 ~ 10%, glycerol 5 ~ 15%, this coupling agent for medical use have high-effective disinfecting sterilization, no cytotoxicity, without hypersensitive, non-irritating characteristic.And for example Chinese invention patent CN102178963B discloses a kind of medical ultrasonic couplant and preparation method thereof, and this medical ultrasonic coupling agent comprises Polyhaxemethylenguanidine Hydrochloride 0.02 ~ 0.2%, viscosity-controlling agent 0.1 ~ 3.2%, glycerol 2 ~ 7%.Sodium hydroxide 0 ~ 0.6, all the other are distilled water, and described medical ultrasonic coupling agent has good coupling, and use comfort strong, ultrasonoscopy is clear, and bacterial virus does not develop immunity to drugs to it, avoids the cross infection on Clinical practice; And for example the Chinese invention patent such as CN102600486B, CN102580122B, CN103432600B, is the coupling agent for medical use that Chinese medicine or industrial chemicals are made all.As mentioned above, the production cost of these coupling agent for medical use is too 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, grease, glycerol, waterglass (sodium silicate Na
2siO
3) or industrial glue, chemical paste, or the special couplant of commercial ultrasound 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 altofrequency 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 sonic 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 ultrasound 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, handwashing liquid 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.
In sum, existing coupling agent for medical use can not possess cheap, the simple and easy to get and advantages such as avirulence of raw material simultaneously; Commercially available industrial couplant can not have the advantages such as cost is low, Detection results good, easy to clean concurrently.
