[0019] A preparation method of a water-washing colored penetrating flaw detection agent, comprising the steps of:

[0020] (1) The fatty alcohol polyoxyethylene ether of described mass fraction, dyestuff, polyoxyethylene alkylphenol ether and water are mixed, and stand-by when stirring for 5 hours;

[0021] (2) Add surfactant and emulsifier into water and stir for 1 hour, then add the mixture prepared in step (1) and continue to stir for 1 hour;

[0022] (3) Filter the mixture in step (2) through a 200-mesh screen to obtain a water-washable colored penetrant flaw detector;

[0023] (4) Fill the penetrant flaw detection agent into an air tank for storage.

Abstract

The invention discloses water-washable dye-penetrant inspection agent, which is prepared from the following raw materials in parts by weight: 10-25 parts of fatty alcohol-polyoxyethylene ether, 1-4 parts of dye, 2-8 parts of emulsifier, 2-4 parts of surfactant, 0.2-1.8 parts of polyxyethylated alkylphenol and 50 parts of water. By use of the water-washable dye-penetrant inspection agent disclosedby the invention, adopted solvent is water, so that environment is not polluted, in addition, water washing can be realized, and meanwhile, color development detection sensitivity is high.

Description

technical field [0001] The invention relates to a penetrant flaw detector, in particular to a water-washing colored penetrant flaw detector and a preparation method thereof. Background technique [0002] Dye penetrant testing is one of five conventional nondestructive testing methods (penetrant testing, magnetic particle testing, radiographic testing, ultrasonic testing, eddy current testing) to detect surface opening defects in non-porous materials. Like other non-destructive testing methods, colored penetrant testing is based on the premise of not destroying the object to be inspected, and effectively inspects various engineering materials, parts and products, so as to evaluate their integrity, continuity, safety and reliability. Penetration testing is an important means of quality control and an indispensable part of product manufacturing and maintenance. [0003] The water-washable high-sensitivity colored penetrant flaw detector is more convenient to use because it is ...
