Transverse wave couplant and preparation method thereof

Abstract

The invention discloses an industrial couplant for metal thickness measurement and a preparation method thereof. The industrial couplant for metal thickness measurement is prepared from raw materials of mixture of honey and one or more carbohydrates. Compared with the prior art, the industrial couplant for metal thickness measurement is advantaged in that (1), the raw materials are cheap, easily available and are the mostly common carbohydrates in market; (2), cleaning is easier compared with other industrial couplants taking machine oil as an example, and the industrial couplant which is for metal thickness measurement and is prepared from the carbohydrate mixture can be cleaned through only water or wiped through paper to accomplish cleaning work; (3), the raw materials are natural, is nontoxic and has high safety; (4), the couplant is neutral, has no corrosion effect on ultrasonic transducers and to-be-detected objects and can be widely utilized; (5), viscosity is greater than 300mpa.s, and the industrial couplant is applicable to various ultrasonic testing instruments; and (6), the detection effect is good, blanks of couplants in domestic are filled, an ultrasonic transverse wave detection development speed in domestic can be accelerated, and the industrial couplant has quite large market values and application prospects.

Description

technical field [0001] The invention relates to an industrial coupling agent for metal thickness measurement, in particular to an industrial coupling agent for metal thickness measurement 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 degree of thinning after being corroded during u...

Problems solved by technology

[0005] 1412mPa·S to 142mPa·S, when the temperature is low, it can barely be applied on the vertical surface; The coating on the back and the front, and the follow-up cleaning work is more troublesome. The engine oil is mineral oil, which does not meet the current environmental protection requirements; Vaseline: can be applied to the front and back, but the follow-up cleaning is troublesome; hydroxymethyl cellulose Although the viscosity can be adjusted according to different needs, there are fine air bubbles that are difficult to eliminate, and the existence of air bubbles will greatly reduce the coupling effect; gel is the optimal viscosity component at this stage, which is non-toxic and harmless, and has a pure and transparent appearance No air bubbles, adjustable viscosity, easy to remove, good rust resistance, stable storage, good sound permeability, etc.
