The plant’s circulating cooling system provides cooling water for the units. The waste heat generated during industrial production processes is generally removed using cooling water. A certain amount of water is drawn from natural bodies of water such as rivers, lakes, and seas as cooling water. The cooling equipment absorbs waste heat, which raises the temperature of the water, before it is discharged back into these rivers, lakes, and seas. This type of cooling method is known as direct flow cooling. When direct current cooling is not available, a cooling tower is required for cooling. The function of a cooling tower is to enable the cooling water carrying waste heat to exchange heat with air inside the tower, thereby transferring the waste heat to the air and releasing it into the atmosphere. For circulating cooling water pumps used in power equipment, it is necessary to have corrosion and wear resistance, especially when transporting seawater or reclaimed water that contains certain levels of chloride ions. According to relevant information, the assessment of water quality regarding steel corrosion is as follows: when PH is between 3 and 11, and the concentration of Cl- + SO42- is 410 + 420 = 830 mg/l, which is greater than 500 mg/l, the corrosion level is considered moderate. The standards for protective measures require the use of coating layers and anti-corrosion layers to isolate the steel from water. Using polyurethane-sprayed elastomers as an anti-corrosion layer provides better protection against Cl- and SO42- ions, and it also has wear-resistant properties that help protect conveying equipment from abrasion. Flue gas desulfurization in thermal power plants is the main method for controlling sulfur dioxide emissions. Flue gas desulfurization in power plants includes dry desulfurization, spray desulfurization, ash desulfurization, and wet desulfurization. Regardless of the desulfurization method used, the inner walls of the slurry pipelines, pumps, and other components need to be coated with anti-corrosion and wear-resistant materials in order to extend the service life of the equipment and ensure the economic viability of the power plant! Glass flakes are widely used in its anti-corrosion and wear-resistant coating, as they can prevent water vapor and chemical solvents from eroding the underlying material. The degree of chemical resistance of the substrate or coating varies depending on the glass raw material used. Glass flakes made of C-glass exhibit excellent chemical durability, a low coefficient of thermal expansion, low cost, and good temperature resistance. The use of glass flake lining increases its heat resistance by 20–40°C compared to similar resin coatings, and therefore it is often used in oil transportation pipelines, hot water pipelines, and heat-resistant chemical processing equipment. However, due to the relatively high coefficient of expansion of glass flakes compared to base materials such as steel and cement, the resin layer tends to crack and peel off under thermal shock, resulting in poor impact resistance. In addition to the aforementioned advantages, polyurethane spray elastomers have better temperature resistance and impact resistance compared to those with peeling scales. It can operate normally over a long period at temperatures ranging from -57°C to 93°C; special models can withstand high temperatures up to 170°C. In a submerged state, its wear resistance is 8 times that of cemented carbide steel and 7 times that of vulcanized rubber. However, the price of polyurethane is higher than that of glass flake.
