Description
Technical field
The present invention relates to a kind of method for anticorrosion treatment of workpiece for making guardrail.
Background technique
Guardrail is seen everywhere, and plays protection, buffer action, and common guardrail is welded using carbon steel, then again
Apply protective layer.Due to installing outdoors, solarization rain and dew, long duration of action is easy corrosion, and present some guardrails use stainless steel
Make, anti-corrosion effect is fine, but stainless steel surface is bright, generates light pollution, it is therefore desirable in stainless steel surface painting, be formed
Matt layer, but because stainless steel surface is too smooth, coating is easily peeled off.
Summary of the invention
The purpose of the present invention is to provide a kind of production method of outdoor guardrail, solves guardrail in the prior art and become rusty with easy
Erosion, the flaky technical problem of surface covering.
To achieve the goals above, the invention patent technical solution is as follows:
A kind of method for anticorrosion treatment for the workpiece making guardrail, production guardrail are made of stainless steel square steel, at anti-corrosion
Science and engineering skill includes the following steps:
Step 1: carrying out wire drawing process to workpiece, surface forms strain line, carries out coarse processing to surface, improves in subsequent
The film adsorptivity of formation；
Step 2: workpiece is completely immersed in pickling solution, pickling time is 20-30 minutes, and the dirt after removing wire drawing is miscellaneous
Object；
Step 3: the workpiece of pickling is cleaned, scavenging period is 3-5 minutes；
Step 4: workpiece is completely immersed in phosphating solution, workpiece surface forms phosphating coat, and phosphating time is 10-30 minutes.
Phosphorating treatment have the effect that 1), workpiece corrosion resistance can be improved.Though phosphating coat is thin, since it is one layer nonmetallic
Non-conductive separation layer can make the excellence conductor of surface of workpiece be changed into non-conductor, inhibit surface of workpiece micro cell
Formation, and then effectively prevent the corrosion of film.2) it, improves workpiece substrate and applies the adhesive force of interlayer.On the one hand, phosphating coat with
Metal works are a compact overall structures.On the other hand, phosphating coat has porosity, and coating is allow to penetrate into this
Among some holes gap, coating is combined closely with phosphating coat, and adhesive force improves.3), clean surface is provided.Phosphating coat is only in no greasy dirt
Could be grown with the surface of workpiece of no rusty scale, therefore, by parkerized metal works, can provide cleaning, uniformly,
The surface of without grease and non-corroding.
Step 5: drying, drying temperature is 110-120 degree, and drying time is 30 minutes, solidifies phosphating coat；
Step 6: electrostatic powder coating, forms zinc coat in workpiece surface, thickness of coating is 60-80 μm.Electrostatic Spraying of powder Coatings
The working principle of coating and the electrostatic spray of general liquid coating are nearly identical, the difference is that powder spray is
Dispersion, rather than be atomized.It is the coating to gush out by electrostatic powder paint gun, keeps powder particle band negative while dispersion
Charge, electrically charged powder particle are applied by the effect of air-flow (or other active forces such as centrifugal force) and electrostatic attraction and arrive workpiece
On；
Step 7: being baked, baking temperature is 180-200 degree, and baking time is 30 minutes, and heating consolidates spraying molten
It is melted into film.
By above-mentioned technique, so that stainless steel work-piece surface is formed the very strong galvanized anticorrosive layer of one layer of adhesive force, is not easy to peel off,
And brightness is low, solves the problems, such as light pollution.
It is further improved, in the step 2, pickling solution is the mixing of 30% dilute hydrochloric acid or 20% dilute sulfuric acid or the two
Liquid
It is further improved, in the step 3, wash number is three times, to clean 3 minutes every time, cleaning solution is clear water.
It is further improved, in the step 4, phosphoric acid,diluted that phosphating solution is 20%.
It is further improved, flat-crushing type wire drawing is used in the step 1.
The present invention has technical effect as is evident below by adopting the above technical scheme:
By above-mentioned technique, so that stainless steel work-piece surface is formed the very strong galvanized anticorrosive layer of one layer of adhesive force, is not easy to peel off,
And brightness is low, solves the problems, such as light pollution.
