Abstract
The invention relates to the technical field of metal product manufacture, in particular to a metal surface anti-corrosion treatment method. The method comprises the following steps of 1) primary rinsing treatment for cleaning dust and metal chips on a metal surface in a rinsing tank; 2) degreasing treatment for cleaning greases on the metal surface in cleaning fluid; 3) secondary rinsing treatment for cleaning metal many times by utilization of clean water so as to remove the cleaning fluid from the metal surface; 4) drying treatment for removing water stains from the metal surface in a drying manner; 5) coating treatment for uniformly spraying anti-corrosive paint on the metal surface. The metal surface anti-corrosion treatment method has the beneficial effects of simple operation and capabilities of effectively improving anti-corrosion property of metal products and improving the service lives of the metal products.
Description
Technical field
The present invention relates to metallic article manufacturing technology field, particularly relate to a kind of anticorrosion treatment method for metal surfaces.
Background technology
Manufacture in process at metallic article, after completing metal turning operation, need the emulsion being bonded at surface of workpiece, greasy dirt, aluminium bits and other impurity etc. to clean up, and want guarantee fund's metal surface dry and comfortable, next procedure can be proceeded to, way in the past first directly sets up sprinkler head at the leading portion of metal pipeline, metal washes away totally by ejection cold water or hot water, then sets up high-power heater and large blower at the back segment of metal pipeline and dried up by metal.Existing matting is complicated, and cleaning performance is poor, can not meet the production requirement of special metal, and in the use procedure of metallic article, usually can be subject to the corrosion in extraneous external environment, affect the service life of metallic article.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of anticorrosion treatment method for metal surfaces simple to operate.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of anticorrosion treatment method for metal surfaces, comprises the following steps:
Step one, first time washes process, washes down dust and the metal fillings of metal surface in rinsing bowl;
Step 2, grease removal process, the grease on clean metal surface in cleaning fluid;
Step 3, second time washes process, utilizes clear water repeatedly to wash down metal, removing metal surface cleaning liquid;
Step 4, dry process, removes the water stain of metal covering by the mode of drying;
Step 5, coating film treatment, at metal surface even application anti-corrosive paint.
On the basis of technique scheme, the present invention can also do following improvement.
Further, in described step one, the temperature of washing trough inner water is 30-40 DEG C, and scavenging period is 1-3min.
Further, in described step 2, described cleaning fluid is the mixing material of water, concentrated type cleaning agent and surfactant, and the free alkali point concentration of described mixing material is 10-20.
Further, in described step 2, described cleaning fluid is organic solvent or dissolves solvent.
Further, in described step 3, the method for cleaning is spray, the number of times of cleaning showers is three times, the temperature of the water that first time sprays is 30-50 DEG C, sprays: 0.1-0.2MPa, spray time 0.5-1.5min, the temperature of the water of second time spray is 70-80 DEG C, spray: 0.3-0.6MPa, spray time 0.5-1.5min, the temperature of the water that third time sprays is room temperature, spray: 0.1-0.3MPa, spray time 0.5-1min.
Further, in described step 5, dry in dryer after anticorrosion with painting erosion paint, bake out temperature is 120 DEG C, and drying time is 10 minutes.
The invention has the beneficial effects as follows: the present invention is simple to operate, effectively can improve the anticorrosive property of metallic article, improve the service life of metallic article.
