The use of various auxiliary materials must be handled with care and should not be applied arbitrarily. Third, for large-scale port machinery and equipment steel structures, the selection of coatings is crucial as it directly affects coating quality, application efficiency, and overall cost. The coating process must strictly follow the specified procedures. High-viscosity thick-film coatings are typically applied using high-pressure airless spraying equipment. This method produces a more effective anti-corrosion coating compared to brushing, making it a preferred choice in industrial applications. Therefore, logistics companies like Shanghai to Guiyang must choose the right construction techniques based on the specific type of coating being used.
6. Although the auxiliary materials used in coatings are not the main film-forming components, they play a significant role in the curing process and the final performance of the coating. These materials include thinners, driers, curing agents, moisture-proof agents, defoamers, plasticizers, and leveling agents. Their primary function is to enhance coating performance, prevent defects, and improve application results. However, improper use can lead to negative consequences. For example, each type of coating requires a specific thinner, and mixing them without proper knowledge may cause issues such as precipitation or reduced drying speed. For instance, using nitrocellulose lacquer as a chlorinated lacquer could result in the precipitation of perchloroethylene resin, while an amine-cured epoxy might react improperly with certain solvents. Therefore, the use of auxiliary materials must be cautious and well-informed.
Third, large-scale port machinery and equipment often involve massive investments, ranging from several million to tens of millions of yuan. Once in operation, these systems are difficult to maintain or repaint due to their critical role in production. Scheduling downtime for maintenance can disrupt operations, especially for dockside equipment that affects berth availability, which can span 20–30 meters or even up to 60–70 meters. Moreover, the challenging on-site conditions make it hard to achieve a satisfactory recoating. As a result, the initial coating becomes increasingly important. It is now expected that the coating life will exceed ten years, with a minimum of five years without any need for maintenance. During this time, the steel structure of the equipment should remain protected without requiring additional painting.
