Abstract
The invention relates to a chemical polishing agent which is applicable to tower material polishing, and comprises the following components mixed in parts by weight: 1-1.5 parts of analytical pure oxalic acid, 1-1.5 parts of analytical pure hydrofluoric acid, 15-20 parts of water, and 17-23 parts of 30% hydrogen peroxide. A use method of the chemical polishing agent which is applicable to the tower material polishing comprises the steps that (1), mother liquor is prepared by oxalic acid, hydrofluoric acid and the water; (2), the mother liquor and hydrogen peroxide are mixed to form the chemical polishing agent; (3), a metallographic grinding surface is wiped by the chemical polishing agent; (4), the metallographic grinding surface is wiped by the method the same as in Step (3) after 30s; (5), the wiped surface is washed by the water; and (6), the surface washed by the water is wiped by alcohol. According to the chemical polishing agent, the on-site polishing time is saved, and the on-site metallographic examination working efficiency is improved.
Description
Technical field
The invention belongs to power equipment and manufacture processing technique field, particularly a kind of chemical polishing agent and using method that is applicable to the polishing of tower material.
Background technology
The in-service electric power pylon of power system, lightning rod steel tower, when carrying out metallurgical analysis, scene must carry out polished finish, purpose is to remove the cut that last one sand paper stays, and to obtain smooth and bright like a mirror flour milling, cleaning and tissue that the quality of polishing directly affects plane was seized present.To be abrasive material by dissolving in polishing fabric reach the polishing purpose to the shear action of sample in traditional mechanical polishing, generally make is flannelette, abrasive material is aluminum oxide or silicon carbide, during polishing, by abrasive material, be suspended in uniformly on fabric, firmly evenly, less exerts pressure, and in-service electric power pylon, the processing of lightning rod steel tower field polish need the time about half hour.
Chemical rightenning is exactly that specimen surface is immersed to chemical agent, the uneven dissolution of sample is reached to the order of polishing by chemical agent, chemical rightenning at present is at electric power pylon, lightning rod steel tower, although scene carries out also using in polished finish work, but the formula of chemical agent is varied, finds a kind of more applicable chemical agent formula to carry out polished finish work and still seem very necessary.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, a kind of chemical polishing agent and using method that is applicable to the polishing of tower material is provided.
The present invention solves its technical problem and takes following technical scheme to realize:
A kind of chemical polishing agent that is applicable to the polishing of tower material comprises the following component that the mark ratio mixes by weight:
And described chemical polishing agent is first by oxalic acid, hydrofluoric acid and water are configured to mother liquor, then with hydrogen peroxide, are mixedly configured into chemical polishing agent.
A kind of using method that is applicable to the chemical polishing agent of tower material polishing, the method step is as follows:
(1) by oxalic acid, hydrofluoric acid and water are made mother liquor by the proportioning of above-mentioned chemical polishing agent;
(2) in job site, mother liquor and hydrogen peroxide are mixedly configured into to chemical polishing agent by the proportioning of above-mentioned chemical polishing agent;
(3) use the polishing surface of chemical polishing agent wiping metallographic;
Interval after 30 seconds again with step (3) same procedure with the polishing surface of chemical polishing agent wiping metallographic;
(5) water rinses the surface after wiping;
(6) the surface after rinsing with alcohol wipe water.
And (3) described step with the concrete grammar on the polishing surface of chemical polishing agent wiping metallographic is: use antimagnetic type tweezer folder medical absorbent cotton, dip in chemical polishing agent, evenly the polishing of wiping metallographic surface 10-15 second firmly.
Advantage of the present invention and positively effect are
1, the present invention is suitable for in-service electric power pylon, the on-the-spot metallurgical analysis chemical rightenning of lightning rod steel tower is processed, and has saved the field polish time used, improves on-the-spot metallographic examination working efficiency.
2, chemical polishing agent of the present invention is easy to carry, and on-the-spot easy to use, cost of manufacture is low, is applicable to application.
