Fence anti-corrosion technology

Abstract

The invention discloses a fence anti-corrosion technology, which is characterized by comprising the following three steps of descaling, paint spraying and wrapping with a heat shrinkable film: (1) descaling: removing the rust of the fence by means of a laser derusting device; (2) paint spraying: spraying epoxy anti-corrosion series paints, wherein the spraying process is as follows: A, when a brush-painting method is adopted for construction, paints should be brushed in the same direction; B, when a spraying method is used, the movement speed of the spray gun should be uniform and the nozzle should be kept perpendicular to the surface to be sprayed; (3) wrapping with a heat shrinkable film: after the anti-corrosion paints are solidified, wrapping with a heat shrinkable film, heating the heat shrinkable film by use of a flame spray gun to make the surface of the fence evenly wrapped with the heat shrinkable film. First, the method uses laser to remove rust, does not need a derusting agent, is convenient and quick to use, and does not pollute the environment; and then, the method performs a painting spraying treatment so that the original rusty part is covered with the anti-corrosionpaints and the fence can be prevented from being corroded; finally, the method covers the fence with the heat shrinkable film to block the tiny rusty points from contacting with the atmosphere, thereby preventing the corrosion of the rusty points which is difficult to observe.

Description

technical field [0001] The invention relates to the field of anti-corrosion technology, in particular to a fence anti-corrosion process. Background technique [0002] Fences are very common facilities in daily life. Existing fence structures usually include vertical bars and horizontal bars, which are generally used as protection or blocking devices. Fences are often used outdoors and are directly exposed to the environment. Although some fences have a surface After anti-corrosion treatment, but after a long time of use, its connection, bump and wear are still prone to rust. If measures are not taken in time, the corrosion rate of this part will be accelerated, thus damaging the fence. It is common to directly remove the damaged part of the fence and replace it with a new fence, which is not only time-consuming and laborious, but also causes waste of materials. Contents of the invention [0003] In order to solve the above-mentioned problems, the present invention provide...
