Our products are characterized by the absence of hydroxyl groups compared to epoxy resins, and the lack of ester bonds compared to vinyl esters, making them resistant to hydrolysis and erosion. This polymer material can cure at room temperature or be forced to cure at low temperatures for immediate use. It is a specially formulated polymer coating suitable for high-temperature and abrasive environments in flue gas desulfurization systems; the coating is a cross-linked organic-inorganic multi-functional polymer with high flexibility and toughness. It can withstand temperatures up to 500F (260°C), tolerate 5,000 types of solvents and oxidizers, and has excellent flexibility, wear resistance, erosion resistance, and impact resistance. Next, let's appreciate a case of this coating used for corrosion protection on a reheater tube.
The coal-fired power plant is equipped with a static precipitator and a wet flue gas desulfurization system. The flue gas after the wet dedusting and washing process can cause certain damage to the alloy structure of the reheating pipes. One obvious issue is the high chloride content in the coal, which can account for 0.03% by weight, leading to 12,000 ppm of chlorides in the flue gas after combustion. The reheating pipes are made of stainless steel at the exit location, and are affected by the chlorides in the flue gas, resulting in pitting corrosion. The water temperature inside the reheating pipes is 200°F, while the external flue gas temperature is 180°F.
