Problems solved by technology

But so far, due to the limitations of shear wave detection (that is, shear wave detection requires a high flatness of the end surface of the object to be tested, that is, the viscosity of the shear wave coupling agent must be large enough during detection), no domestic manufacturer can produce a product that can achieve the above Shear wave couplant for easier shear wave detection

Abstract

The invention discloses a transverse wave couplant for power station boiler steel pipe inner wall oxide-film high frequency ultrasonic measurement, and a preparation method thereof. The transverse wave couplant is prepared by honey and a mixture of one or more than one carbohydrate. Compared with the prior art, the transverse wave couplant has the advantages of: (1) cheap and easily available raw material: most common carbohydrate in the market; (2) easy cleaning: compared with a common machine oil industrial couplant, the transverse wave couplant can be cleaned only by water flushing or paper towel wiping; (3) pure natural raw material which has no poisonous effects and possesses high safety; (4) neutrality: the transverse wave couplant is difficult to corrode an ultrasonic transducer and an object for measurement, and has a wider application scope; (5) viscosity greater than 300mpa: the transverse wave couplant is suitable for various supersonic reflectoscopes; and (6) sound detection effect: the transverse wave couplant is innovative at home, greatly accelerates domestic ultrasonic wave transverse wave detection development, and has high market values and bright application prospects.

Description

technical field [0001] The invention relates to a shear wave coupling agent, in particular to a shear wave coupling agent for high-frequency ultrasonic measurement of an oxide film on the inner wall of a power plant boiler steel pipe and a preparation method thereof. Background technique [0002] Ultrasonic testing equipment adopts the latest high-performance, low-power microprocessor technology, based on the principle of ultrasonic pulse reflection, can measure the thickness of metals and other materials, and can also measure the sound velocity of materials. When the ultrasonic pulse emitted by the probe passes through the measured object and reaches the material interface, the pulse is reflected back to the probe to determine the thickness of the measured material by accurately measuring the time the ultrasonic wave travels in the material. Ultrasonic testing equipment can measure the thickness of various pipes and pressure vessels in production equipment, monitor their de...
