Problems solved by technology

However, during the service process of the transmission tower, in addition to the severe corrosion damage caused by the harsh conditions of sunshine, alternating dry and wet, and weathering, it also has to bear the alternating load of the wind, which may lead to fastening In the actual process, the protective layer is partially damaged and the service life is shortened, especially in harsh environments such as coastal areas, and there may even be serious consequences of losing mechanical strength, which affects its reliability. , endangering the structural safety of transmission towers

Embodiment 1

[0027] A method for protecting fasteners of offshore power transmission poles and towers, comprising the following steps:

[0028] (1) Clean the fasteners of transmission towers, remove water and oil, and remove dust and rust;

[0029] (2) Evenly spray the primer on the fasteners. The mass parts of the primer are: 40 parts of phenolic resin, 10 parts of nano-oxide, 5 parts of methyl cellulose, 5 parts of molybdate, and 30 parts of sulfonated oil share. The paint is sprayed into a fine mist with a high-pressure injector, and the fine mist droplets are evenly mixed during the landing process, and the dispersion is wrapped on the surface of the fastener to form a uniform coating.

[0030] (3) Apply the middle paint as soon as possible after applying the primer. The mass parts of the middle paint are: 0.5 parts of graphene, 50 parts of silicone resin, 1 part of silane coupling agent, and 20 parts of asphalt. The asphalt is obtained by mixing 10# asphalt and 100# asphalt accordin...

[0043] A method for protecting fasteners of offshore power transmission poles and towers, comprising the following steps:

[0044] (1) Clean the fasteners of transmission towers, remove water and oil, and remove dust and rust;

[0045] (2) Evenly spray the primer on the fasteners. The mass parts of the primer are: 45 parts of phenolic resin, 15 parts of nano-oxide, 8 parts of methyl cellulose, 7 parts of molybdate, and 34 parts of sulfonated oil. share. The paint is sprayed into a fine mist with a high-pressure injector, and the fine mist droplets are evenly mixed during the landing process, and the dispersion is wrapped on the surface of the fastener to form a uniform coating.

[0046] (3) Apply the middle paint as soon as possible after applying the primer. The mass parts of the middle paint are: 2 parts of graphene, 60 parts of silicone resin, 3 parts of silane coupling agent, and 30 parts of asphalt. The asphalt is obtained by mixing 10# asphalt and 100# asphalt accordin...

Abstract

The invention provides a method for protecting the fasteners of offshore power transmission poles, which includes the following steps: (1) Cleaning the fasteners of power transmission poles and towers, removing water and oil, and removing dust and rust; (2) Evenly spraying the primer on the (3) Apply the middle paint as soon as possible after applying the primer; (4) Continue to coat the outer paint on the middle paint; (5) Wrap the PE protective film after the paint dries. The paint in the protection method has good adhesion to the fasteners, effectively prevents corrosion of the fasteners, and prolongs the service life.

Description

technical field [0001] The invention relates to a fastening sealing and anti-corrosion protection method for fasteners suitable for power transmission and transformation towers in coastal areas and heavy industrial areas, in particular to a protection method for fasteners of offshore power transmission towers. Background technique [0002] Fasteners are one of the key components of transmission towers, which are related to the reliability and safety of transmission towers. Due to long-term exposure to the atmospheric environment and the long-term erosion of harmful gases such as water vapor, oxygen and wind in the sea atmosphere that have a corrosive effect on the metal surface, the metal itself will inevitably rust, especially in some local atmospheres containing hydrogen sulfide, sulfur dioxide, etc. In the environment of acid gas, coupled with the mixing effect of water vapor in the atmosphere, the corrosion of metal components is aggravated. Metal corrosion will greatly...
