Description

technical field [0001] The invention relates to the technical field of mold production and processing, in particular to a penetrant flaw detection agent used in a penetration flaw detection process. Background technique [0002] The processing technology of the mold includes the following steps: gouging → flaw detection (excluding inclusions and cracks) → scanning → preheating the mold → welding → post-weld heat treatment → scanning → grinding → inspection out of the warehouse. Among them, the flaw detection process is the process operation of detecting cracks or defects inside metal materials or components. Commonly used flaw detection methods include: X-ray flaw detection, ultrasonic flaw detection, magnetic particle flaw detection, penetrant flaw detection, eddy current flaw detection, gamma ray flaw detection and other methods. [0003] The existing patent number is CN201310078214.6, and the Chinese invention patent titled "Fluorescence Penetrant Flaw Detection Agent fo...
