Technical Field

[0001] The present invention relates to the technical field of penetrant flaw detection devices, in particular to a copper material penetrant flaw detection device and a use method thereof. Background Art

[0002] Penetrant testing is a widely used, cost-effective non-destructive testing method, mainly used to detect open defects on the surface of non-porous materials such as metals (including copper and copper alloys), ceramics, and plastics. These defects may include cracks, pores, looseness, folds, cold shuts, etc. Penetrant testing technology originated in the early 20th century. In the early days, the "oil-white method" was used to detect surface defects of metal parts such as railway axles. With the increasing demand for non-ferromagnetic materials in the aviation industry, Americans improved the detection sensitivity by adding coloring dyes and fluorescent agents. Penetrant testing equipment is a combination of a series of equipment, materials and chemical reagents designed for implementing penetrant testing methods. For copper materials, it is an efficient, sensitive, economical and relatively easy-to-operate surface non-destructive testing method. It is widely used in the manufacturing process quality control of copper and copper alloy components, in-service equipment maintenance and safety assessment, helping to timely detect surface defects that may lead to failure, thereby ensuring product quality, equipment safety and operational reliability.

The positively charged penetrant or developer is finally sprayed toward the copper material by the nozzle. Since the copper material and the components connected to it are grounded, the penetrant or developer is negatively charged relative to the positively charged penetrant or developer. Due to the attraction of positive and negative charges, the penetrant or developer is better and more fully adsorbed to the front, side, and even to a certain extent, back (grooves, edges, etc.) of the copper material to be inspected, thereby improving the dead angle problem that is difficult to cover with traditional spraying and improving the flaw detection effect.

The penetrant or developer entering the fifth connecting tube 14121 will be positively charged when passing through the honeycomb ionization plate 14122. The positively charged penetrant or developer is finally sprayed toward the copper material by the nozzle 14124. Since the copper material and the parts connected to it are grounded, the penetrant or developer is negatively charged relative to the positively charged penetrant or developer. Due to the attraction of positive and negative charges, the copper material is better and more fully adsorbed to the front, side and even to a certain extent the back (grooves, edges, etc.) of the copper material to be inspected, thereby improving the dead angle problem that is difficult to cover with traditional spraying and improving the flaw detection effect.
