Anti-corrosion spraying process based on polytetrafluoroethylene material

Abstract

The invention discloses an anti-corrosion spraying process based on a polytetrafluoroethylene material. The anti-corrosion spraying process based on the polytetrafluoroethylene material comprises thefollowing steps that 1, the surface treatment is carried out on a rolled steel, specifically, the cleaning treatment is carried out on the surface of the rolled steel firstly, sundries and stains on the surface of the rolled steel is washed and cleaned by using pressure water of 290 Kpa, and the time length is 10-15min; then an abrasive paper is used for grinding treatment, projections on the surface of the rolled steel is polished uniformly, and the roughness of the surface of the rolled steel reaches about 20 microns; a fluorocarbon diluting agent is used to wipe the surface of the rolled steel cleanly, and exposing and airing are carried out to obtain the clean and polished rolled steel. According to the anti-corrosion spraying process based on the polytetrafluoroethylene material, through the multiple spraying step process and the anti-corrosion function of the polytetrafluoroethylene material, the adhesiveness of the coating rolled steel is improved, the coating is not prone to fall off in use, and the quality of the rolled steel is improved; and meanwhile, the combination degree among primer, finish paint and the rolled steel is improved, the gap condition is avoided in the coating, the anti-corrosion property and the wear resistance of the rolled steel are greatly improved, and a good application prospect is realized.

Problems solved by technology

[0002] With the development of the economy, various industries such as chemical industry, petroleum, shipbuilding, power plants, public utilities, etc. have increasingly urgent requirements for corrosion protection of pipelines and pumps, and their grades have been continuously improved. Specifically refers to polytetrafluoroethylene, and the anti-corrosion spraying process refers to spraying coatings on items to achieve anti-corrosion effects and avoid items being rusted; while the existing anti-corrosion spraying process based on PTFE materials, PTFE materials are used in other The spraying effect is not uniform during the spraying process, and the anti-corrosion time is short during use, which may cause shedding. At the same time, the adsorption effect is not good, so that there is a gap between the topcoat and the primer, resulting in corrosion, which affects the quality of the product. Service life, for this reason, we propose an anti-corrosion spraying process based on PTFE material
