Abstract
The invention relates to a polishing agent applicable to boiler equipment and pipelines of power plants. The polishing agent is prepared from, by mass, 1.5-2 parts of 5% nitric acid, 1-1.2 parts of analytically pure oxalic acid, 1-1.2 parts of analytically pure hydrofluoric acid, 20-23 parts of 30% hydrogen peroxide and 15-20 parts of water. The utilization method of the polishing agent includes steps: (1) proportionally mixing the nitric acid, the oxalic acid, the hydrofluoric acid and water to obtain mother liquor; 2) proportionally mixing the mother liquor with hydrogen peroxide at a work site to obtain the polishing agent; (3) using a stainless steel tweezers for clamping medical absorbent cotton, and dipping the polishing agent to scrub a metallographic polish surface; (4) repeating the step (3) after 30s; (5) flushing the scrubbed surface with water; (6) using ethyl alcohol for scrubbing the surface flushed with water. The polishing agent is suitable for onsite metallographic chemical polishing treatment of the boiler equipment and the pipelines of the power plants, onsite polishing time is saved, and onsite metallographic inspection efficiency is improved.
Description
Technical field
The invention belongs to power equipment manufactures processing technique field, particularly one kind is applied to boiler of power plant equipment and pipeline
Polishing agent and using method.
Background technology
Boiler of power plant equipment and pipeline, carry out must being processed by shot blasting during Metallographic Analysis at the scene, to remove last
The vestige that one sand paper stays, the quality of polishing directly affects the cleaning checking face and tissue presents.The more commonly used having
Optical polishing and mechanical polishing, the time of mechanical polishing is longer, typically more than half an hour, so multiplex chemical polishing at the scene,
Chemical polishing is exactly that specimen surface is immersed in chemical reagent, to reach polishing by chemical reagent to the uneven dissolution of sample
Purpose, current chemical polishing is commonly used in the field polish of boiler of power plant equipment and pipeline, but the formula of chemical reagent
Varied, find a kind of the relatively difficult of suitable application, therefore find a kind of suitable chemical polishing reagent and be polished not
Only can make what metallographic structure became apparent to show, but also polishing time can be shortened, improve work efficiency.
Content of the invention
The purpose of the present invention is for the deficiencies in the prior art, and proposes a kind of boiler of power plant equipment and pipeline of being applied to
Polishing agent and using method.
The present invention solves its technical problem and takes technical scheme below to realize:
A kind of polishing agent being applied to boiler of power plant equipment and pipeline, comprise by mass fraction constitute following component:
And, described polishing agent is first configured to mother solution by nitric acid, oxalic acid, Fluohydric acid. and water, then mixes with hydrogen peroxide and joins
It is set to chemical polishing agent.
A kind of using method of the above-mentioned polishing agent being applied to boiler of power plant equipment and pipeline, method and step is as follows:
(1) mother solution is configured to by the proportioning of above-mentioned chemical polishing agent by nitric acid, oxalic acid, Fluohydric acid. and water；
(2) in working site, mother solution and hydrogen peroxide are mixedly configured into chemical polishing agent by the proportioning of above-mentioned polishing agent；
(3) use antimagnetic type tweezer to press from both sides medical absorbent cotton, dip in chemical polishing agent, uniformly firmly wipe the polishing surface of metallographic
10-20s；
(4) repeat after 30s to operate according to step (3)；
(5) rinse the surface after wiping with water；
(6) use the surface after the flushing of alcohol wipe water.
Advantages of the present invention and good effect are:
1st, the present invention is suitable for boiler of power plant equipment and pipeline field metallographic chemistry polishing, saves field polish institute
Time, improve the work efficiency of live metal lographic examination；
2nd, the chemical polishing agent of the present invention is easy to carry, and onsite application is convenient, low manufacture cost.
Specific embodiment
Hereinafter the embodiment of the present invention is further described: it is emphasized that embodiment of the present invention is explanation
