Tentation indicates that the use of this developer, a penetrate and a cleaning solution which are high temperature modification liquid penetrate tests can finish the surface inspection of object which the surface temperature is 150-220DEG Cand can detect a fracture whose breadth is 0.001mm and width depth ratio is 1/60.
Description
Technical field
The present invention relates to the flaw detection on metal, compact nonmetallic material and product surface thereof, particularly a kind of high-temperature type dye check cleaning liquid that is used for material or surface of the work flaw detection and preparation method thereof.
Background technology
The liquid penetrant examination method is a kind of important method in the modern Non-Destructive Testing, originates in the World War II initial stage, is used for war industry the earliest.Become at present in the modern manufacturing industry for improve the quality of products, service equipment safely, prevent a kind of important means of industry disaster accident.This method can detect that material or surface of the work occur also in the extremely trickle fracture focus of bud.
The ultimate principle that infiltration detects is with a kind of material (overwhelming majority is a liquid, and also having a spot of is gas and solid, so claim that generally it is a bleeding agent), infilters in the microscopic checks and goes; Wipe up with the cleaning fluid bleeding agent cleaning that the next door is unnecessary then, keep the bleeding agent in the crack as far as possible; Again imaging liquid is applied to surface of the work, this reagent can very fast volatilization and stay the solid film that one deck has strong absorption affinity, the bleeding agent that stays in the microscopic checks is sucked out and is enlarged, and makes it to demonstrate the place, position in crack.
Existing penetrant flaw detection agent is made up of penetrating fluid, cleaning fluid and imaging liquid, through development for a long time, the employed penetrant flaw detection agent of liquid penetration test that has occurred multiple model in the world, but this class penetrant flaw detection agent, can only detect surface temperature and be in-10 ℃---70 ℃ workpiece.When existing penetrant flaw detection agent is applied to 70 ℃ of high temperature surfaces, can evaporates immediately, seethe with excitement, bubble, smolder, what have also can burn, can't operate as normal.But the high temperature workpiece exists really real-life, for example: carry the pipeline of high-temperature steam and high temperature fluid, boiler in the work and pressure vessel, parts after the hot-working just, electric welding weldment soon and be near the workpiece thermal source etc.
Some workpiece must at high temperature carry out penetrating inspection, and check that again reason is as follows the temperature of workpiece can't be dropped to below 70 ℃ the time:
1. some power house, particularly nuclear power station, oceangoing voyage boats and ships and chemical industry facility, they Once you begin move, can not stop, but their boiler, pipeline waited until certain time limit and needed maintenance to have only some position of determining to have and just locally after the problem stop work, repair or change parts midway.The inspection of comprehensively search property can only be under the condition of high temperature of carrying labour at them to be carried out;
2. some hot-working parts is in order to guarantee the quality of following process, process inspection in the middle of need doing, if cooling, may need the long time cycle, also to heat up again after checking and continue processing, so not only waste energy, also may be in the process of temperature one rise and one drop, change the metallographic structure of material, damaged their mechanical property;
3. some pressure vessel has the heat leak situation to exist, and in other words, it is under high-temperature condition, open because of radial pressure makes microscopic checks, can leak fluent meterial wherein, after its cooling, microfracture is closed again, leaks very not obviously, and such source of leaks has only that at high temperature check could be effective.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of high-temperature type dye check cleaning liquid that at high temperature carries out permeation flaw detection and preparation method thereof to satisfy the needs of high temperature flaw detection.
The present invention solves the problems of the technologies described above the technical scheme that is adopted:
A kind of high-temperature type dye check cleaning liquid that is used to be in the surface of the work flaw detection under the high temperature, formulated by dibatyl phithalate, strychnine and colloid silit, it is as follows that it forms proportioning:
Composition wt%
Dibatyl phithalate 50-80
Strychnine 15-25
Colloid silit 5-25
The preparation method of described high-temperature type dye check cleaning liquid comprises the following steps:
1. select technical pure or chemical pure raw material for use, comprise strychnine, dibatyl phithalate and colloid silit;
The proportioning of 2. selected high-temperature type dye check cleaning liquid, weighing step each raw material described in 1.;
3. with step 2. in peaceful, the colloid silit of institute weighing taxi and the dibatyl phithalate of part amount mix, be in harmonious proportion, form temper;
4. described temper is pulled an oar, form slurry, beating time 〉=1.5 hour;
5. with step 3. in remaining dibatyl phithalate mix with described slurry, place in the heating reactor and stir, slowly be warming up to 280 ℃ in the whipping process, stop heating then and be stirred to 180 ℃ stopping to stir;
6. filter the liquid that stirred, filtered fluid is cooled to room temperature.Promptly get high-temperature type dye check cleaning liquid;
7. the painted cleaning fluid of described high temperature modification is in bulk or fill into the aerosol jar.
The technique effect of high-temperature type dye check cleaning liquid of the present invention and preparation method thereof is:
This cleaning fluid is used with high-temperature type dye check developer and high-temperature type dye check penetration liquid, and can finish surface temperature is the flaw detection on 150～220 ℃ product surface, and detecting width is 0.001mm, and breadth depth ratio is 1/60 crack.
Embodiment
