Problems solved by technology
Due to its own composition and structure, bitumen will crack after a long time of use, and the tape itself is not strong enough and easy to break
Therefore, when bitumen tape is used for anticorrosion of metal pipelines laid in the natural environment, the anticorrosion safety is often not guaranteed.

Embodiment
[0008] Embodiment: first smear with rust anti-corrosion paint on the metal pipeline, then evenly smear epoxy bitumen adhesive on the rusty paint, wrap a layer of glass fiber cloth evenly on the epoxy bitumen adhesive, Then apply epoxy bitumen adhesive evenly on the glass fiber cloth, and then evenly cover and wind the glass fiber cloth of the same specification on the adhesive, so that it can be wound back and forth for 10 layers, and it can be cured at room temperature.

An anticorrosion process for wrapping metal pipeline with glass fiber reinforced plastics includes coating a layer of anticorrosive paint around the metal pipeline, painting adhesive and covering with wound glass fiber bundle or glass fiber fabric repeatedly for 5-20 layers, and curing at normal temperature. Thus formed glass reinforced plastics coating has high anticorrosive effect and high strength and can raise the anticorrosive effect and prolong the service life the metal pipeline effectively.
Description
technical field [0001] The invention relates to a method for anticorrosion of metal pipelines by covering metal pipelines with glass cloth to form FRP coating. Background technique [0002] Metal pipelines are often used for the long-distance transport of various substances. Some transmission metal pipelines are erected in the air, some are laid in trenches, and some are buried underground. Either way, metal pipelines will be corroded when in contact with surrounding substances, which will affect the life of metal pipelines and the safety of transmission. [0003] In the past, bitumen tape was mainly used for anticorrosion of the outer surface of metal pipelines. Due to its own composition and structure, bitumen will crack after a long time of use, and the adhesive tape itself is not strong enough and easily damaged. Therefore, when bitumen tape is used for anticorrosion of metal pipelines laid in the natural environment, anticorrosion safety is often not guaranteed. Co...
