Technical Field

The invention relates to the technical field of metal corrosion prevention, in particular to a corrosion prevention process of an iron art railing.

Background

The railing is widely applied in daily life and mainly plays a role in decoration and protection. Along with the improvement of aesthetic value of people, the requirements on the shape and the shape of the handrail are more and more, when the handrail with complex pattern and special shape is produced, the phenomenon of uneven surface is easily generated due to the bending deformation of materials and the like, so that the situation that the handrail is not processed in place easily during the rust prevention and corrosion prevention treatment is easily generated, when the handrail is applied, particularly applied outdoors, the handrail is easily corroded again under the condition of rainwater erosion, the appearance is influenced, and the danger is also caused under the condition of serious corrosion.

Taking an iron art rail as an example, at present, in order to make anticorrosion treatment, the surface of the iron art rail is generally subjected to treatment processes of polishing, derusting, coating with antirust paint and paint. In the treatment process, equipment is needed to spray a cleaning agent on the surface of the handrail, and then rust is cleaned. The spraying equipment is generally large in scale, and a transport vehicle and the like need to be sprayed close to the railing; meanwhile, when spraying equipment is used for spraying on the surface of the handrail, the surface of the handrail often flows downwards in a water flow shape, and the spraying uniformity is poor, so that the surface of the handrail is not thoroughly rusted and cleaning agent waste is generated; in addition, in order to pursue beauty, the shapes of the conventional railing are different, and when a cleaning agent is sprayed by using spraying equipment, the penetration of the cleaning agent into a crack position cannot be guaranteed, which is another factor causing incomplete cleaning; these factors lead to the disadvantage of poor corrosion resistance during subsequent application of the rust inhibitive paint, which in turn affects the aesthetics of the balustrade.
