Wax coating is a kind of high-temperature coating, which is mainly used in the internal protection of tanks, anti-corrosion coatings for cooling towers and other fields. The following are the application areas of wax-based coatings:
Tank internal protection: Wax coating can effectively protect the inner wall of the tank and prolong the service life.
Cooling tower anti-corrosion coating: Wax coating is a commonly used cooling tower anti-corrosion coating, which can effectively form a dense shielding barrier layer to prevent chloride ions, SO2, SO3, H2S, CO2, microorganisms and other corrosive media from eroding concrete and causing corrosion.
Shipbuilding and marine engineering: Wax coatings can be applied to anti-corrosion coatings in ships, marine engineering and other fields, which can effectively isolate the oxidation and corrosion of seawater, oxygen and other substances on the substrate.
Pipelines, storage tanks, oil tanks: Wax coatings can be applied to anti-corrosion coatings in pipelines, storage tanks, oil tanks and other fields, which can effectively isolate the oxidation and corrosion of air, water, oxygen and other substances on the substrate.
Other fields: Wax coatings can also be applied to some high-temperature equipment, stoves, ovens and other fields of anti-corrosion coatings, which can effectively isolate the oxidation and corrosion of the substrate in a high-temperature environment.
The function of wax coatings in the anticorrosive coating of cooling towers is to form a dense shielding barrier layer to prevent corrosive media such as chloride ions, SO2, SO3, H2S, CO2, and microorganisms from eroding the concrete and causing corrosion.
Specifically, wax coatings can effectively penetrate into the concrete capillaries, produce an anchoring effect, close the capillaries of the concrete substrate, and increase the surface strength of the matrix, thereby preventing the oxidation and corrosion of concrete by moisture, oxygen and other substances. In addition, the film-forming agent in wax coatings can form a thin film to effectively isolate the oxidative corrosion effect of air, water, oxygen and other substances on concrete, so as to achieve the purpose of anti-corrosion.
Therefore, wax coating is a very important anti-corrosion material in the anti-corrosion coating of cooling towers, which can effectively protect the service life and safety of cooling towers.
The application of wax coatings in anticorrosive coatings for cooling towers is mainly used as a kind of heavy anticorrosive coatings. Among them, Dilling 441, Diling 4941, Diling L142, Diling 1000 inorganic anticorrosive coatings are commonly used wax coatings, which can react quickly with iron atoms on the surface of steel structures to produce inorganic polymer anticorrosive coatings with physical and chemical dual protection and firm bonding with the matrix through chemical bonds. This kind of coating has no pollution to the environment, long service life, anti-corrosion performance has reached the international advanced level, is a high-tech replacement product that meets the requirements of environmental protection, and is also a good anti-corrosion coating on the cooling tower. In addition, the corrosion resistance of Dilin heavy anticorrosive wax anticorrosive coating is not only better than that of organic coatings, but also the service life will reach more than 10 years, which is an ideal repair material, which can increase the surface strength of concrete and the durability of the coating, and improve the permeability resistance of the coating. Therefore, wax coatings are an important application in anti-corrosion coatings for cooling towers.
