Rigid waterproof casing how to anti-corrosion

A kind of rigid waterproof casing is used to protect and limit the pipeline through the wall. Since the pipeline is corrosive, rigid waterproof casing has an important significance for the corrosion of the pipeline. In the process of pipeline corrosion protection, in addition to ensuring the quality of pipeline materials, it is also necessary to ensure its construction method and construction process. Therefore, in the pipeline anti-corrosion construction, the quality of pipeline materials should be guaranteed to be reliable, and reasonable construction methods and construction techniques should be adopted to ensure that their construction methods and construction techniques meet the requirements stipulated in the current standards. To ensure that the pipeline anti-corrosion construction is carried out smoothly must deal with the anti-corrosion layer of the pipeline itself, such as: the quality of the painting process and construction quality should be strictly controlled when painting the anti-corrosion layer. In addition, it is necessary to ensure that the pipeline material in the anti-corrosion construction does not seriously affect the normal operation of the pipeline.
In the pipeline coating construction, it is necessary to ensure that the pipeline coating surface is free of bubbles, pockmarks, porosity, oxidation skin and other defects and delamination. After the pipeline coating construction is completed, the pipeline coating surface should be sandblasted to ensure that the pipeline surface is smooth, flat and free of defects such as pockmarks. After the pipeline coating construction is finished, the pipeline surface also needs to be sanded. Generally, the surface of the pipeline will have a certain depth. When its surface roughness is large or there are obvious pockmarks on the surface of pipeline material, the construction personnel should sand the pipeline surface. The grinding process can make the surface roughness of the pipeline smaller, and the surface of the pipeline will not have defects such as cracks.
The main measure of pipeline corrosion protection is to use electrochemical and chemical leaching treatment technology, but for different environments such as between the pipe and the pipe, between the pipe and the concrete and between the concrete and the concrete to apply, it is necessary to choose the corresponding treatment method according to the specific situation. Between the pipe and the pipe body, the main anti-corrosion method is electrochemical leaching, the main principle of which is that the current forms a polarization current in the pipe, so that chemical corrosion occurs inside the pipe under the influence of potential difference. Specifically, an electric current is introduced inside the pipe, which is directly related to the quality and chemical corrosion condition of the pipe. Between pipelines, the main corrosion protection methods are chemical leaching and electrochemical descaling. Chemical leaching is the chemical leaching method to achieve the protective effect on the anticorrosive coating.
