At the beginning of the new year of 2004, the successful development of functional epoxy powder coating curing agent technology from Suzhou Shengjie Specialty Resins Co., Ltd. marked the protection of reinforced steel cables and cable-stayed bridges and the anti-corrosion of oil and gas pipelines. Special motor insulation protection coatings are expected to be widely applied in China.
In addition to the solvent-free environmental features, functional powder coatings perform well in the protection of building steel. The steel in the concrete of a building will be corroded by alkaline cement on the one hand, and acid gases such as carbon dioxide in the humid air will also be eroded through the cement voids. If not protected, the service life of the building will be damaged due to the reinforcement. And shortened. In response, developed countries have long passed legislation to develop standards for the protection of building steel bars, and regulations stipulate the steel bars used in buildings. Special powder coatings must be sprayed before use. At present, the protection of reinforced concrete coatings for concrete buildings in China has not yet started. Instead, the protection of steel cables of cable-stayed bridges has gradually shifted from grease protection to functional coating protection. However, the products used are imported. The reason for this status quo is that the cost of imported products is too high. On the other hand, the domestic technology is not enough, and the concept of application is behind.
Pure epoxy resin functional powder coatings require high technical performance, and must have excellent flexibility, ductility and chemical resistance, so as to ensure that the building steel is not damaged during the process of bending, stretching and impact; It is required to have “cohesion†adhesion with steel and cement at the same time so as not to cause hidden troubles such as shelling and blistering when combined with one or both parties “not closeâ€; its quality index must be 100% compliance, because in the entire building, If there is a point that does not meet the protection requirements, it will affect the overall strength of the building. At present, there are only a handful of multinational corporations internationally that can meet this technical requirement.
Suzhou Shengjie Specialty Resins Co., Ltd. strives to reduce costs while technically researching. The product price is 60% to 70% of that of similar foreign products, providing good conditions for large-scale promotion of pure epoxy functional powder coatings in China. It is reported that the Ministry of Construction and the General Administration of Quality, Technology, and Supervision, Inspection and Quarantine of the People's Republic of China have now embarked on the formulation of the standards for the protection of building steel bars and will enforce them in high-rise buildings within the next two or three years.
In addition, excellent properties make functional powder coatings versatile. For example, the advantages of anti-corrosion on the inner wall of oil and gas pipelines are not comparable to other traditional products. Because of its good flame-retardant properties, it is a good product for the motor industry to replace flammable enameled wires, and has broad application prospects.
