Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to the field of material detection, and in particular to a self-emulsifying fluorescent penetrant performance adjustment method. BACKGROUND
[0002] The self-emulsifying fluorescent penetrant is a solution containing fluorescent dye and having strong penetration ability. It can penetrate into surface opening defects and be adsorbed by the developer, thereby showing the trace of the defect. The self-emulsifying fluorescent penetrant is the most critical material in the water washing type fluorescent penetrant testing, and its quality directly affects the quality of the penetrant testing. The basic components of the self-emulsifying fluorescent penetrant are fluorescent dye, oily solvent, penetrating solvent, emulsifier, etc. Its characteristics are strong penetration ability, and since it contains emulsifier, it can be directly washed with water, and the cost is relatively low. The formula of this type of penetrant is relatively complex, and the formula of different types and different brands is different.
[0003] When water enters the self-emulsifying fluorescent penetrant, due to the presence of emulsifier, the emulsifier absorbs water, and the water will not directly sink to the bottom of the tank. Its water pollution resistance is weak. Especially when the water content in the penetrant exceeds the water capacity, turbidity, separation, precipitation and sensitivity decrease will occur.
[0004] The self-emulsifying fluorescent penetrant contains emulsifier, which is miscible with water, and acid and chromate are easy to react with the dye in the penetrant, affecting the sensitivity of the test. The self-emulsifying fluorescent penetrant is most susceptible to water, acid and chromate, metal chips, dust and other pollutants during the use of the penetrant testing, which directly damages its physical and chemical properties and reduces its sensitivity. In the material consistency test project, it is easy to approach or exceed the specified value or state, which seriously affects the production. SUMMARY
