Embodiment 1

[0017] A treatment method for cable anticorrosion, the method comprising the following steps:

[0018] (1) Surface treatment: Use ethanol as a solvent to remove oil and grease on the surface of the cable, then use electric tools to remove loose rust and scale on the substrate, and keep the substrate clean and dry. In order to prevent re-oxidation and rust, Apply as soon as possible after cleaning;

[0019] (2) Apply epoxy zinc-rich paint evenly once, the dry film thickness is 0.04 mm, and wait for hard drying (about 24 hours), the theoretical dosage is 314g / m 2 ;

[0020] (3) Apply epoxy zinc-rich paint evenly once again, the dry film thickness is 0.04mm, wait for hard drying (about 24 hours), the theoretical dosage is 314g / m 2 ;

[0021] (4) Apply epoxy topcoat evenly once, the dry film thickness is 0.05mm, wait for hard drying (about 24 hours), the theoretical dosage is 122g / m 2 ;

[0022] (5) Apply the epoxy topcoat evenly once again, the dry film thickness is 0.05mm, ...

Abstract

The invention relates to a treatment method for corrosion prevention of a cable. The method comprises the following steps of: performing surface treatment: removing oil stains and grease on the surface of the cable by adopting ethanol as a solvent, then removing rusty stains and an oxide skin on the surface, further sequentially coating two layers of epoxy zinc-rich paint and two layers of epoxy finish paint on the surface of the cable, and finally coating silver powder paint and performing zinc supplement appearance treatment. Compared with the prior art, the cable obtained by the treatment method disclosed by the invention has a corrosion prevention function, a protection layer laid on the outer side can well protect the cable in the protection layer from being corroded so as to expand the range of applications of the cable, and the treatment method is particularly suitable for occasions with harsh environments and inconvenience in replacement, such as a tunnel and the like.

Description

technical field [0001] The invention relates to a method for anticorrosion treatment, in particular to a treatment method for cable anticorrosion. Background technique [0002] With the continuous expansion and renewal of the power grid, in order to meet the needs of the development of the power system, the voltage level of the urban network transmission line is continuously improved, and the cross-section of the cable is also continuously increased. Since the tunnel does not occupy the ground space and can be constructed in advance, it is ready for the future cable laying facilities, solves the problem of road damage during multiple constructions, and is conducive to the improvement of city appearance and environment. The design and application of power cable tunnels are increasing day by day. [0003] Due to the long and narrow space of underground power tunnels and many obstacles, high-temperature and dense smoke tends to accumulate in the event of a fire, making it diffi...
