Description
Technical field
The present invention relates to a kind of penetrant flaw detection agent, and in particular to a kind of high temperature dye check agent and preparation method thereof.
Background technology
Liquid penetrant examination method is a kind of important method in modern Non-Destructive Testing, turns into raising product quality, and maintenance is set
Standby safety, prevent a kind of important means of industry disaster accident.
The general principle of Liquid penetrant testing is to infilter penetrating fluid in minute crack, then with cleaning fluid by the unnecessary penetrating fluid in side
Clean up, ensure penetrating fluid be present in only minute crack, then crack position is shown by imaging liquid.It is but existing
Conventional penetrant flaw detection agent can only detect the workpiece that surface temperature is in -10 DEG C~70 DEG C, if being applied to high temperature surface, it is formulated
In many ingredient stabilities it is low, easily there is bubble, evaporation is even smoldered the phenomenon of burning, but usually can in existing detection
High temperature workpiece is run into, original most common way was to allow workpiece to suspend from the duty originally to work, and carries out being cooled to less than 70 DEG C and is being examined
Survey.
But thering are some workpiece to carry out Liquid penetrant testing, such as power station at high temperature, petrochemical industry, once it run
Midway can not just stop, and its internal boiler, and pipeline has to periodically be overhauled, and to ensure safety, will now face
Carrying out flaw detection under high temperature.
The content of the invention
Goal of the invention：The invention aims to make up the deficiencies in the prior art, there is provided a kind of high temperature dye penetrating is visited
Hinder agent, it can meet the Liquid penetrant testing under 150 DEG C of high temperature, without equipment stop production detect, greatly improve detection efficiency and
Accuracy.

Selenium nitrogen red 1~4 part and 0.7~1.2 part of propellant.
Further, the penetrant flaw detection agent is formulated by the raw material of following parts by weight, phthalic acid di-isooctyl 40~50
Part, 8~10 parts of polyoxyethylene fatty acid ester, peaceful 30~35 parts of taxi, the parts by weight of surfactant 10~15, red 2~3 parts of selenium nitrogen
And 0.8~1.0 part of propellant.
A kind of preparation method of high temperature dye check agent, comprises the following steps：
(1) by the polyoxyethylene fatty acid ester of the mass fraction, taxi is peaceful, surfactant, and selenium nitrogen is red, propellant and
The phthalic acid di-isooctyl of partial amount mixes, and is beaten and forms slurry；
(2) the remaining phthalic acid di-isooctyl of addition in step (1), is placed in heating response kettle, is stirred at 400 DEG C
10min is mixed, then stops heating, continues stirring to being cooled to 250 DEG C and stops stirring；
(3) mixture of step (2) is filtered by the screen cloth of 200 mesh, is subsequently cooled to room temperature acquisition high temperature and
Color penetrant flaw detection agent；
(4) penetrant flaw detection agent is filled with gas tank and preserved.
Beneficial effect：A kind of disclosed high temperature dye check agent, can meet oozing under 150 DEG C of high temperature
Detection thoroughly, stop production and detect without equipment, greatly improve detection efficiency, while it can realize 1 μm of wide crack, detection essence
Exactness is high.
