If there is a problem such as corrosion or damage to nuclear power equipment, it may not be able to ensure the normal and stable operation of nuclear power plants, and even lead to environmental problems. The improvement of anti-corrosion performance of nuclear power equipment can greatly extend the service life of nuclear power equipment, increase its operation stability and safety, and anti-corrosion rubber lining can be widely used in seawater desalination, nuclear power, hydropower, wastewater treatment, flue gas desulfurization, food, chemical and mineral processing equipment and other fields. Therefore, taking into account the advantages of rubber anti-corrosion lining technology, such as reliability, economy, safety and life, nuclear power technology can be combined with rubber anti-corrosion lining technology, so that nuclear power equipment can be more safe and stable power generation.
Seawater contains many electrolyte ions such as sodium ions, chloride ions, etc., which makes seawater corrosive to equipment. In seawater desalination equipment, in addition to the characteristics of elasticity and low permeability, rubber's special molecular structure allows it to be coated in the outer layer of nuclear power equipment to increase the corrosion resistance of nuclear power equipment. At present, anti-corrosion rubber replaces coating and mortar as the protective lining of equipment, so that the equipment can maintain stable operation for a long time without interference from the corrosive sea water. Therefore, the use of anti-corrosion rubber lining can extend the service life of the equipment to a certain extent, and increase the safe operation rate and reliability rate of the unit. The main rubber with anti-corrosion function are neoprene rubber, butyl rubber, natural rubber, ethylene propylene rubber and fluorine rubber. According to the different use environment and equipment materials, rubber varieties that meet the requirements can be selected. In addition, different nuclear power equipment has certain requirements for the mechanical properties and adhesion of anti-corrosion rubber, so it is necessary to modify anti-corrosion rubber to a certain extent. For example, graphene has excellent chemical stability, adding an appropriate amount of graphene to the anti-corrosion rubber can prepare a new type of anti-corrosion rubber, it not only has the cathodic protection in the original rubber, and its water resistance and hardness are also higher, so the overall anti-corrosion performance has been improved. In addition, a series of improvements and innovations to the rubber preparation process can also improve the performance of rubber to a certain extent.
