Embodiment Construction

[0019] The preferred embodiments of the present invention are described in detail below, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0020] A solvent-removable colored penetrant flaw detection agent in this embodiment includes a penetrant and an imaging agent, and the components of the penetrant include: 34.4 parts of absolute ethanol, 12 parts of dioctyl phthalate, and 15 parts of rhodamine , 33 parts of kerosene and 3.2 parts of triethanolamine. Adding triethanolamine improves the cleaning performance of the penetrant, making the penetrant easier to clean. The components in the developer include: 80 parts of absolute ethanol, 12 parts of titanium dioxide, 5 parts of gas-phase powder, 3 parts of calcium carbonate and 1.2 parts of triethanolamine. Adding triethanolamine improves the cleaning performance of the developer and ...

Abstract

The invention discloses a solvent removal type dye penetrant flaw detection agent and a preparation method thereof. The solvent removal type dye penetrant flaw detection agent comprises penetrant anddeveloper, wherein the penetrant comprises absolute ethyl alcohol, dioctyl phthalate, rose essence, kerosene and triethanolamine, and the developer comprises absolute ethyl alcohol, titanium dioxide,gas phase powder, calcium carbonate and triethanolamine. By adding the components, a flash point of the penetrant is increased, problems of strong taste and pungent smell are solved, wettability of the penetrant is further improved, so the penetrant is easy to clean when flowing on the skin, the developer is easy to clean and remove when flowing on a surface of a workpiece, and use of the dye penetrant flaw detection agent is facilitated.

Description

technical field [0001] The invention relates to the field of penetrant flaw detection, in particular to a compound solvent-removable colored penetrant flaw detection agent and a preparation method thereof, which are used for detecting opening defects on the surface of workpieces and belong to the technical field of non-destructive detection colored penetrant flaw detection. Background technique [0002] Conventional non-destructive testing methods are generally divided into five types: penetrant testing, magnetic particle testing, radiographic testing, ultrasonic testing, and eddy current testing. Colored penetrant testing is a method of penetrant testing, which is used to detect surface opening defects of non-porous materials. Dyeing penetrant inspection is based on the premise of not destroying the inspected object, and effectively inspects various engineering materials, parts and products, so as to evaluate their integrity, continuity, safety and reliability. Dyeing penet...
