How to improve the corrosion resistance of the main structure of the Roof Pressure Stabilizing Pump Station through anti-corrosion treatment? ​

In the production process of the roof pressure stabilizing pump station, ensuring that the main structure has good corrosion resistance is a key link to ensure the long-term and stable operation of the equipment. In order to improve the corrosion resistance of the main structure of the pump station, a series of carefully designed anti-corrosion treatment processes will be started after the welding is completed. Each step plays an important role in improving the durability of the pump station. ​
After the welding of the main structure of the pump station, there will be problems such as uneven welds, residual welding slag and surface oxide layers caused by high-temperature welding. These defects not only affect the beauty of the structure, but more importantly, they will become weak points for the invasion of corrosive media. Therefore, the welding parts must be polished and leveled first. By using professional grinding tools, the weld and the surrounding areas are polished to a smooth and flat surface, eliminating the bumps, depressions and sharp edges on the surface. This operation can not only remove impurities left by welding, but also enable the subsequent anti-corrosion coating to better adhere to the metal surface and enhance the bonding between the coating and the substrate. ​
After the grinding and leveling is completed, the primer coating work will be carried out immediately. Primer plays a vital basic role in the entire anti-corrosion coating system. Its main function is to provide excellent adhesion and preliminary anti-rust protection. Usually, coatings with good adhesion and anti-rust properties are selected, such as epoxy zinc-rich primer. This primer uses epoxy resin as a film-forming substance and adds a large amount of zinc powder as an anti-rust pigment. Zinc powder has an electrochemical protective effect. When the coating surface is damaged or defective, the zinc powder will undergo oxidation reaction before the base metal, thereby protecting the metal base from corrosion. When the primer is applied, the coating process must be strictly controlled to ensure that the coating evenly covers the entire main structure surface to avoid defects such as missing coating and sagging. Only a uniform and complete primer coating can lay a solid foundation for subsequent coating construction. ​
After the primer is applied and dried and cured, the intermediate paint is applied next. The intermediate paint mainly plays the role of increasing the coating thickness and improving the shielding performance of the coating in the anti-corrosion coating system. As the coating thickness increases, the path for the corrosive medium to penetrate into the surface of the metal substrate becomes longer, thereby slowing down the corrosion process. There are many types of intermediate paints, the most common of which are epoxy micaceous iron intermediate paints. This type of intermediate paint contains flake pigments such as mica iron oxide. These flake pigments are arranged parallel to each other in the coating to form a multi-layer shielding structure, which can effectively block the penetration of corrosive media and further improve the anti-corrosion performance of the coating. The coating of the intermediate paint also needs to strictly follow the process requirements, and by controlling the number of coatings and the thickness of the coating, ensure that the designed anti-corrosion standards are met. ​
Finally, the topcoat is applied. The topcoat is in the outermost layer of the entire anti-corrosion coating system and is in direct contact with the external environment. Its main function is decoration and protection. When choosing the type of topcoat, it will be determined according to different use environments. For general indoor environments, acrylic polyurethane topcoat is a common choice. This topcoat has good weather resistance, wear resistance and decorative properties, which can keep the appearance of the pump station beautiful and tidy, while providing certain protection for the lower coating. In some highly corrosive outdoor environments or industrial environments, fluorocarbon topcoat is more advantageous. Fluorocarbon topcoat is based on fluorocarbon resin, which has super weather resistance, chemical corrosion resistance and self-cleaning properties. It can protect the main structure of the pump station for a long time under harsh environmental conditions and reduce coating aging and corrosion caused by environmental factors. ​
Different use environments have different challenges to the corrosion resistance of the main structure of the top plate pressure-stabilizing pump station. In a humid environment, moisture is easy to condense on the metal surface to form an electrolyte solution, which accelerates the electrochemical corrosion process of the metal. At this time, the anti-corrosion coating needs to have good waterproof properties to prevent moisture from contacting the metal matrix. In an industrial environment containing chemical media such as acids and alkalis, the coating needs to have excellent chemical corrosion resistance and be able to resist acid and alkali erosion. By reasonably selecting the combination of primer, intermediate paint and topcoat, and controlling the construction quality of each coating, the main structure of the pump station can be adapted to various complex use environments. ​
Anti-corrosion treatment can not only improve the corrosion resistance of the main structure of the top plate pressure-stabilizing pump station, but also improve the overall performance and service life of the equipment from multiple aspects. A good anti-corrosion coating can reduce the decline in structural strength caused by corrosion and ensure that the pump station always maintains stable structural performance during long-term operation. This is crucial for the main structure of the pump station that bears pressure and stress, and can effectively reduce the risk of safety accidents caused by structural damage. At the same time, it avoids the cost of equipment repair and replacement caused by corrosion, reduces the time of equipment downtime maintenance, improves the operating efficiency and reliability of the pump station, and enables the pump station to continuously and stably provide pressure guarantee services for various fields.
