Abstract

The invention relates to the technical field of penetrant flaw detection, in particular to a washing type dye flaw detection penetrant taking water as a developer, and a preparation method and a use method thereof. The flaw detection penetrant comprises the following components in parts by weight: 5-15 parts of a coloring dye, 5-15 parts of an organic compound, 30-50 parts of a solvent, 20-40 parts of an emulsifier and 1-5 parts of a defoaming agent, the organic compound is a natural terpenoid or organic resin. The problem that in the prior art, the penetrant flaw detection process is complex is solved. According to the washing type dye flaw detection penetrant, water serves as a developing agent to replace a traditional white developing agent, after the flaw detection penetrant on the surface of a workpiece is washed with water, the developing agent does not need to be sprayed after drying, a water film left on the surface of the workpiece serves as the developing agent, a coloring agent permeating into cracks is sucked to the surface of the workpiece according to the capillary principle, and whether the surface of the workpiece has defects can be observed by placing for a while.

Description

technical field [0001] The invention relates to the technical field of penetrant flaw detection, in particular to a water-washing colored flaw detection penetrant with water as an imaging agent, a preparation method and a use method. Background technique [0002] Colored flaw detection penetrant is a non-destructive flaw detection method based on the principle of capillary action to inspect the surface opening defects (cracks, pores, looseness, delamination, incomplete penetration and incomplete fusion, etc.) of dense materials, also known as PT detection. [0003] With the rapid development of my country's manufacturing industry, the variety of special performance materials is increasing (forgings, castings, weldments, machined parts, ceramics, glass, plastic powder, metallurgical parts, etc.), especially when the workpiece is overhauled in the field. The flaw detection method and the fluorescent penetrant flaw detection method cannot meet the requirements, so the colored pe...
