Abstract

The invention relates to Sudan IV dye penetrant, which is particularly suitable for dye inspection of castings. The Sudan IV dye penetrant contains the following components by weight percent: 0.9g / 100ml Sudan IV, 30 percent of acetone and 70 percent of kerosene. The Sudan IV dye penetrant can satisfy the requirements on the practical use in casting inspection and has no harmfulness to human bodies, so inspectors can use the Sudan IV dye penetrant conveniently and safely.

Description

Technical field [0001] The invention relates to a sudan No. 4 colored penetrating agent, which is especially suitable for casting color inspection. Background technique [0002] Coloring inspection is basically the same as fluorescent inspection in terms of materials and methods except that visible light is used instead of fluorescent coloring in the penetration process. Its advantage is that defects can be found under general white light. This method is to infiltrate the colored penetrant into the surface defects of the casting, then remove the excess penetrant, and apply the developer to the casting. Due to capillary action, the colorant is sucked up from the surface to color the developer, so , to determine the position and approximate shape of the defect from the color-changed image. [0003] The colorant formula is very important, and the colorants generally formulated in the market often cannot meet the requirements for use. Contents of the invention [0004] The i...
