Problems solved by technology

Although the flaw detection agent of this invention patent has certain advantages compared with traditional organic solvent-based products, it still has the following disadvantages: 1) The formula contains polluting ingredients (dyes, adsorbents, etc.), which are easy to cause environmental pollution, It does not meet the current environmental protection requirements; 2) The sensitivity to fine cracks on the surface of the workpiece is not high enough, and can only reach 0.0001mm

Embodiment 1

[0025] 1) Preparation of black wolfberry-red yeast rice mixed extract

[0026] Freeze-dry the naturally air-dried black wolfberry with a freeze dryer, then mix it with red yeast rice at a mass ratio of 5:1 (that is, 5 parts of black wolfberry and 1 part of red yeast rice), grind it to obtain a mixed powder, and add equivalent Mix ethanol with 3 times the mass of the powder, soak for 1 hour, and filter to obtain a mixed extract of black wolfberry-red yeast rice.

[0027] 2) Preparation of colorant

[0028] i. Take 20 parts of nonionic surfactant and 20 parts of black wolfberry-red yeast rice mixed extract, mix and stir evenly to prepare a colorant.

[0029] ii. Put the colorant prepared in the above step i into an aerosol can, install an aerosol valve, and then fill with 60 parts of hydrofluoroalkane to prepare the colorant.

[0030] 3) Preparation of developer

[0031] i. Get 10 parts of cellulose nanofibers, 2 parts of dioctyl phthalate, 1 part of fatty acid triethanolamid...

Embodiment 2

[0034] Different from Example 1, in this embodiment, when preparing the mixed extract of black wolfberry-red yeast rice, the mass ratio of black wolfberry and red yeast rice is 2:1, and the amount (quality) of ethanol is 1 / 2 of the mixed powder mass. 2 times, the soaking time is 1.5 hours.

Embodiment 3

[0036]Different from Example 1, in this embodiment, when preparing the mixed extract of black wolfberry-red yeast rice, the mass ratio of black wolfberry and red yeast rice is 3:1, and the amount (quality) of ethanol is 1 / 2 of the mixed powder mass. 2.5 times, soaking time is 1 hour.

[0037] Practice shows that in Example 1, the liquid output of the black wolfberry-red yeast rice mixed extract is relatively large, which is more suitable for large-scale production.

Abstract

The present invention relates to a non-destructive flaw detector which includes a colorant and a color developing agent; the colorant comprises the following raw materials by mass: 20 to 25 wt% of a non-ionic surfactant, 20 to 30 wt% of a lycium ruthenicum-red yeast rice extract mixture, and the balance of a propellant; the color developing agent comprises the following raw materials by mass: 6 to10wt% cellulose nanofiber, 2 to 3wt% of a plasticizer, 1 to 2wt% of a surfactant, 7 to 10wt% of an adsorbent, 30-40wt% of ethanol, and the balance of the propellant; the non-destructive flaw detectoris not only environmentally-friendly, but also has the advantage of high detection sensitivity; moreover, the colorant and the color developing agent of the non-destructive flaw detector are ejectedby means of the propellant to the surface of a workpiece to be detected, and the non-destructive flaw detector has the advantage of simple and convenient operation.

Description

technical field [0001] The invention relates to the technical field of nondestructive flaw detection, in particular to a nondestructive flaw detection agent. Background technique [0002] Non-destructive testing refers to the use of changes in thermal, sound, light, electricity, magnetic and other reactions caused by abnormal internal structures or defects of materials without damaging or affecting the performance of the tested object and the internal organization of the tested object. , by means of physical or chemical methods, with the help of modern technology and equipment, to inspect the structure, nature, state and type, nature, quantity, shape, position, size, distribution and changes of the internal and surface of the test piece and test methods. Non-destructive testing is an indispensable and effective tool for industrial development, which reflects the industrial development level of a country to a certain extent. The importance of non-destructive testing has been...
