Problems solved by technology

It can be seen that when using the above two flaw detection agents to detect flaws on the surface of the object under test, people need to observe the surface of the object under test in a short period of time to determine whether there are microcracks on the surface of the object under test. , it will not be possible to observe the existence of micro-cracks, which may lead to missed detection

Embodiment 1

[0029] 1) Prepare material A

[0030] Take 0.01 part of fluorescent yellow 3G, 0.02 part of fluorescent red Gg, 0.2 part of nano-titanium dioxide, 0.05 part of nano-silver, and 2.5 parts of deionized water, mix and stir evenly, and prepare material A for later use.

[0031] 2) Prepare material B

[0032] Add 30 parts of ethanol successively in the material A that makes, 1.2 parts of nano-chitosan, 0.5 part of cationic cellulose, 0.02 part of dimethyl phthalate (plasticizer), isomerism decanol polyoxyethylene ether ( Surfactant) 0.017 part, fatty alcohol polyoxyethylene ether (penetrating agent) 0.014 part, silanol nonionic surfactant (wetting agent) 0.007 part, stir well, and prepare material B for later use.

[0033] 3) Preparation of flaw detection agent

[0034] The prepared material B is equally divided into aerosol cans, and the aerosol valve is assembled, and then 40 parts of propane butane and 45 parts of hydrofluoroalkane are equally divided into each aerosol can to pr...

Embodiment 2

[0036] The difference from Example 1 is that in this example, the proportioning ratio of each raw material component is shown in Table 1.

Abstract

The invention relates-a nondestructive flaw detection aerosol. The nondestructive flaw detection aerosol comprises, by weight, 1-1.5 parts of nano-chitosan, 0.5-0.8 part of cationic cellulose, 0.01-0.02 part of a plasticizer, 0.01-0.02 part of a surfactant, 0.01-0.015 part of a penetrant, 0.005-0.008 part of a wetting agent, 0.01-0.02 part of fluorescent yellow 3G, 0.01-0.02 part of fluorescent red Gg, 0.1-0.2 part of nanometer titanium dioxide, 0.05-0.06 part of nano-silver, 2-3 parts of deionized water, 20-30 parts of ethanol, 30-40 parts of propane and 35-45 parts of hydrofluoroalkane. Compared with flaw detectors in the prior art, the nondestructive flaw detection aerosol in the invention has the advantages of specific raw material components and ratio, realization of the detection ofsurface micro-cracks of a workpiece by fluorescent dye emitting visible lights after absorbing sunshine, no combination with other products, novel and unique use mode, and convenience in use.

Description

technical field [0001] The invention relates to the field of aerosols, in particular to an aerosol for non-destructive testing. Background technique [0002] Non-destructive testing refers to the use of light, electricity, magnetism, heat and other reactions caused by internal or surface defects of the detected object to detect physical and / or chemical damage without damaging the object or affecting the performance of the object. It is a method for checking and determining the structure, nature, state, and type, shape, nature, quantity, size, position and changes of the internal and surface of the workpiece. Non-destructive testing reflects a country's industrial development level to a certain extent. At present, the mainstream non-destructive testing techniques mainly include four types: radiographic testing, ultrasonic testing, magnetic particle testing and liquid penetrant testing. Other non-destructive testing techniques include acoustic emission testing, eddy current ...
