The use of various auxiliary materials must be handled with care and should never be done 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 specifications outlined in the coating guidelines. High-viscosity, thick-film coatings are typically applied using high-pressure airless spraying equipment. This method results in a more effective anti-corrosion coating compared to brushing. Therefore, logistics companies like Shanghai to Guiyang must choose the appropriate construction techniques based on the specific 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 performance of the final coating. These materials include thinners, driers, curing agents, moisture-proof agents, defoamers, plasticizers, and leveling agents. Their primary purpose is to enhance coating performance, prevent defects, and improve application characteristics. However, they must be used correctly; otherwise, they can cause adverse effects. For example, each type of coating requires a specific thinner, and using them interchangeably can lead to problems. For instance, when nitrocellulose lacquer is mixed with chlorinated lacquer, the perchloroethylene resin may precipitate. Similarly, using an amine-cured epoxy with ester-based solvents can slow down the curing process, affecting the final film properties. Hence, the use of auxiliary materials must be cautious and not done without proper understanding.
Third, large-scale port machinery and equipment often require high-quality coatings due to their massive investment. The cost of such equipment ranges from several million to tens of millions of yuan. Once in operation, maintenance and repainting are difficult because these machines are critical to production, making it challenging to schedule downtime. Onshore equipment maintenance can also disrupt berth usage, which can span 20–30 meters or even up to 60–70 meters. Moreover, the large size of the equipment and poor on-site conditions make it hard to achieve satisfactory coating renewal. As a result, the initial coating becomes increasingly important. It is now expected that the coating will last over 10 years, with a minimum of 5 years without requiring any maintenance. During this time, the steel structure of the equipment should remain protected without needing additional coatings.
