Embodiment 1

[0015] Embodiment 1, under the condition of normal temperature and pressure without open flame, weigh by weight ratio: take 20 kg of curing agent 650 type low molecular weight polyamide resin liquid, 20 kg of adhesive 6101 type epoxy resin liquid, and 300 mesh zinc of conductive medium Powder 35kg, 300-mesh aluminum powder 15kg and solvent xylene 10kg, put them into the explosion-proof mixer one after another, after stirring evenly, it becomes a conductive repair function glue, brush it evenly on the surface of the iron tower component, put the component into In the pressure tank, cover and inflate, stop inflating when the air pressure is 5kg, exhaust after 50 minutes, open the cover, take out the components, and form a film at room temperature. Then weigh according to the weight ratio, take: 90kg of tung oil, 0.1kg of methyl silicone oil, and 9.9kg of xylene solvent, put them in an explosion-proof mixer under normal temperature and pressure, and without open flames, and stir t...

Embodiment 2

[0017] The manufacturing process is the same as in Embodiment 1. When the air pressure in the pressure tank is adjusted to 3kg, only 60% of the pores, pinholes, and gaps in the galvanized layer of the component are filled, and it is still air-permeable, water-permeable, and has the electrochemical protection function of zinc and the self-healing protection of aluminum oxide film. The function has not been repaired, and the problems of porous corrosion, crevice corrosion and layered corrosion still occur, and the purpose of anti-corrosion and prolonging the service life of the iron tower cannot be achieved.

Embodiment 3

[0019] The manufacturing process is the same as in Embodiment 1. When the air pressure in the pressure tank is adjusted to 4kg, 98% of the pinholes, pores, and gaps in the galvanized layer of the component are filled, and the protective function of the zinc and aluminum coating on the component is basically restored.

Abstract

The invention relates to an anti-rusting method of a galvanized iron tower member. The anti-rusting method is mainly used for solving the problems that, the galvanized iron tower member is not corrosion-resistant, easy to get rusty and short in service life, the structural strength is reduced, the potential safety hazard is generated, and collapse and power outage accidents of an iron tower are further caused in the prior art. The process of the method according to the invention is as follows: brush-coating a conductive glue solution with the repair function on the surface of the assembled galvanized iron tower member, further pressing the glue solution into gas holes, hair eyes, gaps and exposed scars in a galvanized layer through the high pressure method for tamping, blocking and sealing, spray-coating anti-aging, water-repellent and dirt-resistant clear lacquer on the surface of a glue film after the glue film is hardened, brush-coating a silicon rubber layer at the part which is 1m away from the member at the root part of the iron tower after the lacquer forms a film, and further preparing the product prepared by the method according to the invention. The anti-rusting method of the galvanized iron tower member is scientific, simple in process and convenient to use, and can save the material cost, the implementation can be followed after the galvanization process of a galvanization workshop, and the product has the advantages of corrosion resistance, rustless property, friction resistance, water resistance, pollution prevention, long service life of 30 years, maintenance-free updating, safety, reliability and significant economic benefits and can be widely used on land and in water.

Description

Technical field [0001] The invention relates to a corrosion-resistant method for galvanized iron tower components. Background technique [0002] At present, iron towers in domestic and foreign electric power, communication and other departments have been blackened and corroded to varying degrees, and the structural strength has decreased, resulting in potential safety hazards. For this reason, collapses and power outages caused by corrosion continue to occur in our country every year, especially in China. The season of wind, snow and ice is the most serious, causing huge direct or indirect economic losses, which has become a major problem at home and abroad. In order to solve this problem, the relevant departments have adopted the method of on-site anti-corrosion engineering of iron towers and replacing new iron towers. These methods have problems in varying degrees, such as: the anti-corrosion construction of iron towers is a high-altitude operation, which is very dangerous...
