Abstract
The invention discloses a cleaning agent for a high-temperature fracture surface of heat-resistant steel and application thereof. The cleaning agent is prepared by mixing each 100 milliliters of 10 to 15 percent hydrogen chloride (HCL), 3 to 20 drops of glacial acetic acid and 0.05 to 0.2 gram of sodium dodecyl benzene sulfonate completely. The cleaning agent is readily available in materials, and a preparation method is simple and convenient; and the cleaning agent is easy and convenient to operate, can remove oxides on the high-temperature fracture surface of the heat-resistant steel effectively, and has an obvious effect.
Description
Technical field
The present invention relates to a kind of cleansing composition, particularly, relate to a kind of clean-out system for high-temperature fracture surface of heat-resistant steel and application thereof.
Background technology
Use in high temperature steel high-temperature and durable or tension test process in short-term at boiler, after sample fracture, fracture surface can be by oxidation rapidly in hot environment, to the obstacle that fracture apperance is observed and composition analysis formation is larger subsequently, some present fracture cleaning methods adopt the high temperature thermokalite to boil or electrochemical method mostly, and processing condition complexity and pollution and energy consumption are larger relatively.Therefore, need a kind of relatively quick, easy cleaning reagent of exploitation.
Summary of the invention
The purpose of this invention is to provide a kind of cleaning reagent, be used for cleaning the high-temperature fracture surface of heat-resistant steel oxide compound, this clean-out system raw material is cheap and easy to get, the preparation method is easy, is applied to clean the high-temperature fracture surface of heat-resistant steel oxide compound easy and simple to handle, and is quick, cleaning performance is obvious, can remove most of oxide skin.
For realizing above purpose, the invention provides a kind of clean-out system for high-temperature fracture surface of heat-resistant steel, this clean-out system is by every 100ml 10 ~ 15%HCl, 3-20 drips glacial acetic acid and the 0.05-0.2g Sodium dodecylbenzene sulfonate mixes fully.Preferably, described clean-out system is by every 100ml 15%HCl, and 3-5 drips glacial acetic acid and the 0.1g Sodium dodecylbenzene sulfonate mixes fully.Above-mentioned clean-out system component only needs to mix fully and gets final product, and making method is easy and quick.Wherein, hydrochloric acid is used for controlling sour environment, and glacial acetic acid is used for regulating switching speed, and Sodium dodecylbenzene sulfonate is as tensio-active agent.
The present invention also provides a kind of above-mentioned application that is used for the clean-out system of high-temperature fracture surface of heat-resistant steel, this clean-out system is used for cleaning the oxide compound of high-temperature fracture surface of heat-resistant steel, concrete grammar is: with the fracture face of sample to be cleaned up, be placed in clean-out system quiet to 1-5 minute, until fracture surface has bubble to occur; Then, sample to be cleaned is taken out, adopt acetone soln, ultrasonic cleaning.
Clean-out system provided by the invention, raw material is cheap and easy to get, and the preparation method is easy, and this clean-out system uses easy and simple to handle, quick, can effectively remove the oxide compound of high-temperature fracture surface of heat-resistant steel, successful.
Description of drawings
Fig. 1 is 1500 times of microscopic appearance figure that sample to be cleaned arrives by scanning electron microscopic observation.
1500 times of microscopic appearance figure that Fig. 2 arrives by scanning electron microscopic observation for the sample that cleaned.
Embodiment
Describe the specific embodiment of the present invention in detail below in conjunction with drawings and Examples.
Embodiment 1
Amount by table 1 is mixed hydrochloric acid, glacial acetic acid and Sodium dodecylbenzene sulfonate fully, the configuration clean-out system.
The fracture surface of sample to be cleaned has blue high temperature oxidation color, as shown in Figure 1, is 1500 times of microscopic appearances by scanning electron microscopic observation sample to be cleaned, and the complete oxidized skin in surface covers.
This sample to be cleaned is placed in the clean-out system of embodiment 1 gained, fracture up, standing 5 minutes, until fracture surface has bubble to occur; Then, sample is taken out, adopt acetone soln, ultrasonic cleaning 2 minutes is taken out the sample that cleaned, can be observed sample and exposed metalluster clearly, the oxidation color disappears, and this sample is by 1500 times of patterns of scanning electron microscopic observation, as shown in Figure 2, oxide skin is removed substantially, and the matrix pattern occurs substantially.
Embodiment 2 ~ 3
Press the same method of embodiment 1, take the composition and engineering condition of table 1, process sample to be cleaned, the sample after cleaning, the oxidation color disappears, and oxide skin is removed substantially.
Composition and engineering condition and the effect of table 1: embodiment 1 ~ 3
| Agent prescription | Embodiment 1 | Embodiment 2 | Embodiment 3 |
| Hydrochloric acid | 100ml 10% | 100ml 12% | 100ml 15% |
| Glacial acetic acid | 20 | 5 | 3 |
| Sodium dodecylbenzene sulfonate | 0.02 | 0.1 | 0.2 |
| Scavenging period | 5 minutes | 3 minutes | 1 minute |
| Ultrasonic wave (acetone) | 2 minutes | 2 minutes | 3 minutes |
| Effect | The oxidation color disappears, and oxide skin is removed substantially | The oxidation color disappears, and oxide skin is removed substantially | The oxidation color disappears, and oxide skin is most of to be removed |
Can be found out by upper table 1, clean-out system raw material of the present invention is cheap and easy to get, and making method is easy, and the clean-out system that makes is used for cleaning the oxide on surface of high temperature fracture, and is convenient and swift, and treatment effect is obvious.
Although content of the present invention has been done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to limitation of the present invention.After those skilled in the art have read foregoing, for multiple modification of the present invention with to substitute will be all apparent.Therefore, protection scope of the present invention should be limited to the appended claims.
