Corrosion of concrete pipes used in flood control projects is a complex problem. Environmental factors are one of the important reasons for the corrosion of concrete pipes. The pH, salt content, oxygen content and microorganisms in the soil can cause corrosion to concrete pipes. In addition, moisture in the soil, changes in the water table, and contaminants in the soil can also cause damage to concrete pipes. The quality of the concrete pipe itself also affects the corrosion resistance of the pipe. During construction, poor pipeline connection will cause corrosion of concrete pipes.
In view of the above situation, how to solve the problem of anti-corrosion of pipelines? First, it is necessary to choose the best concrete pipe. The second is to master the connection process and not cause construction defects. Third, prepare anti-corrosion coatings for pipelines. For example, the preparation of KNM22 hydrochloric acid anticorrosive coating. KNM22 hydrochloric acid anticorrosive coating is prepared mainly using polymer as the main ingredient, in which hydrochloric acid is added to increase its resistance to corrosive environments. By using hydrochloric acid anti-corrosion coatings, we can effectively extend the service life of equipment and reduce repair and replacement costs.
