Abstract
Steel structure is widely used in modern buildings, its anticorrosive coating construction technology and performance evaluation is of great significance to ensure structure safety and prolong service life. In this paper, the key links of anticorrosive coating construction technology for steel structure are discussed, including surface treatment, coating selection, coating process and construction environment control, etc., and the evaluation methods and standards of anticorrosive coating performance are deeply analyzed, aiming at providing scientific basis for the construction and quality control of anticorrosive coating for steel structure. In terms of construction technology, this paper emphasizes the importance of surface treatment of steel structure, pointing out that rust removal is the first step of anti-corrosion coating construction, and must reach the specified rust removal grade to ensure a good combination of coating and substrate. At the same time, the choice of coating is also the key, should be based on the use of steel structure environment, anti-corrosion requirements and economic factors such as comprehensive consideration, choose the appropriate anti-corrosion coating. In terms of coating process, this paper introduces a variety of coating methods, such as brushing method, rolling coating method, air spraying method and high pressure airless spraying method, and elaborates their advantages and disadvantages and applicable conditions. In addition, the control of the construction environment is also a factor that cannot be ignored, and it is necessary to ensure that the construction environment temperature, humidity and ventilation conditions meet the requirements of the coating product manual. In terms of performance evaluation, this paper introduces several evaluation methods such as coating thickness test, adhesion test, visual inspection, salt spray test, weather resistance test and chemical resistance test. These evaluation methods can fully reflect the performance characteristics of anti-corrosion coatings, including coating thickness, adhesion, corrosion resistance, weather resistance and chemical stability. Through these evaluation methods, the problems existing in the coating can be found in time, and the corresponding remedial measures can be taken to ensure the quality of the anti-corrosion coating of steel structure. The construction technology and performance evaluation of anti-corrosion coating on steel structure is an important link to ensure the safety of steel structure and extend the service life. By optimizing construction technology, strengthening quality control and scientifically evaluating coating properties, the anti-corrosion effect and service life of steel structures can be significantly improved, providing a strong guarantee for the safety and sustainable development of modern buildings.
