In China, the start of heavy-duty anti-corrosion coatings is basically synchronized with the reform and opening up, which started late. In 2011, China's heavy-duty anti-corrosion coatings made brilliant achievements, the output and performance of coatings were greatly improved, and the application scope and service life were increased to varying degrees. However, there are still many problems to be solved in China's heavy-duty anti-corrosion coating industry.
1、 It takes environmental protection, energy saving, high performance and functionalization as the development focus of heavy-duty anti-corrosion coatings and coatings. Environment friendly long-term antifouling coatings must be developed in the next five years; Develop anticorrosive coatings based on composite phosphate Antirust Coatings to replace heavy metal anticorrosive primers such as red lead and chromate that pollute the environment; High solid, solvent-free and water-based anti-corrosion coatings gradually replace the traditional solvent-based coatings; We should also develop and promote waterborne anti-corrosion coatings and waterborne epoxy floor coatings.
2、 It is a standardized market. At present, the coating standards for offshore platform anti-corrosion, railway bridges, vehicles, shipbuilding, ship repair and container loading industries and naval ships are relatively sound, while the industrial standards and supporting systems for sewage treatment systems in petrochemical, electronics, food and other fields are still being formulated, and some markets show disorderly competition and non-standard competition. For example, the industrial floor involves a wide range of industries and is difficult to standardize. Even if the national standard is formulated, it is difficult to cover its application fields, which is easy to cause disorderly competition and hinder the normal development of the industry.
3、 It is necessary to strengthen the research on paint construction performance and coating process to ensure the reliability of products. Starting from the concept of coating integration, pay attention to the coating construction performance - the adaptability of coatings to different substrate treatment degrees, the adaptability of coatings to construction methods and construction processes, and the adaptability of coatings to construction environment. Continuously optimize and improve the comprehensive performance of products, strengthen the coating supporting system and performance evaluation, improve the scientificity and rationality of the supporting system, and adapt to the requirements of different corrosive environments. It is the coating process, surface treatment and supporting system in the maintenance or recoating process of equipment and facilities. Due to different corrosion and construction environment, different damage conditions of the original coating and poor construction conditions, it should be paid great attention.
