Embodiment 1

[0029] Calculated by weight percentage, the penetrant formula provided by the invention is as follows:

[0030] Ethanol 20

[0031] Diethylene glycol ether 10

[0032] Glycerol 10

[0033] Natural fatty acid amides 1

[0034] Natural fatty alcohol polyoxyethylene ether 5

[0035] fluorescent red 1

[0036] rose red 2

[0037] Other additives 3

[0038] The remainder is water;

[0039] Its preparation method comprises the following steps:

[0040] 1. Select industrial-grade or chemically pure raw materials that meet environmental protection requirements, and weigh according to claims 1 and 2.

[0041] ②At room temperature, according to the order of the raw materials listed, add each component to the water one by one. After each raw material is added, it must be fully dissolved before adding the next one. The resulting solution was filtered through a 200-mesh sieve before testing.

[0042] ③ Conduct a sensitivity test on the solution obtained above, and if an artificia...

Abstract

The invention belongs to the detection technology method for the surface discontinuity of metal and nonmetal workpieces, and particularly relates to an environment friendly water-based coloring-fluorescent double-sensitivity penetrant and the preparation method thereof. The penetrant adopts water as the primary solvent, and the other components of the penetrant mainly comprises a penetrating solvent, fatty alcohol amide, natural fatty alcohol polyoxyethylene ether, dyes, other additives, etc. The preparation method comprises the following steps: screening the raw material; metering; distributing the raw material; filtering; checking; bottling; etc. The penetrant has the advantages of high sensitivity and double-sensitivity, allows a crack with an opening width of 0.1Mum to be detected, and is applicable to observation in sunlight or under the irradiation of a black light lamp in a dark room. Since the water is adopted as the primary solvent, the penetrant has the advantages of environment friendly material, flame resistance, non-environmental pollution, safe application, low preparation cost, etc.

Description

technical field [0001] The invention belongs to the technical field of discontinuous detection on the surface of metal and non-metal workpieces, and in particular relates to an environment-friendly water-based coloring-fluorescence dual-sensitivity penetrant and a preparation method thereof. Background technique [0002] Penetrant testing is one of the five non-destructive testing methods commonly used today. Since its development in 1934, with the development of technology, the scope of use of penetrant flaw detection has become wider and wider, and the products and equipment used have become more and more advanced, and its role in the field of workpiece surface detection has also become more and more important. At the same time, with the development of technology, the environmental protection awareness of the whole society is getting stronger and stronger, and the environmental protection requirements for various industrial products are becoming more and more stringent, an...
