Corrosion Protection System
MUCHEN’s anti-corrosion coating products mainly include inorganic zinc-rich coating, organic zinc-rich coating, silicone coating, epoxy coating, acrylic coating, polyurethane coating, fluorocarbon coating, polysiloxane coating and other types of anti-corrosive coatings, which can be divided into land industrial heavy-duty anti-corrosion coatings and marine heavy-duty anti-corrosion coatings according to different application scenarios. According to the material to realize anti corrosion and fight against corrosion mechanism, the coatings can be divided into steel structure anti-corrosion coatings and non-steel structure anti-corrosion coatings.
Among them, the land heavy-duty anti-corrosion coatings are mainly used in the field of petrochemical equipment and structures, including various equipment in the petrochemical production process, such as petroleum refining equipment, chemical reactors, storage tanks, and supporting steel frames and support structures. These facilities are often exposed to harsh working environments and are susceptible to corrosion. Corrosion control measures are critical to extending the structural life of equipment and ensuring work safety and production quality.
Marine anti-corrosion coatings are mainly applied to the field of steel structure corrosion protection for transport ships, containers, sea bridges, port machinery, oil pipelines, offshore oil platforms and other large facilities, marine anti-corrosion products for non-steel structures are mainly anti-corrosion coatings for marine concrete structures.
Characteristics of Anti-Corrosion Coatings
① Good physical properties.
Good impermeability to corrosive media and good adhesion to steel surface;
② Good mechanical properties.
Resistant to seawater scouring, sea ice collision, and abrasion from ship docking.
③ Excellent chemical properties.
Resistant to seawater, salt spray, oil, chemicals and ultraviolet rays.
④ Good compatibility with electrochemical protection systems.
Coatings in the splash zone and full immersion zone should be resistant to cathodic disbonding;
⑤ Good workability;
The coatings should be able to be used for high-quality application on different structures under various environmental conditions;
⑥ Compliance with health, environmental protection and safety requirements.
The coating is required to have a high solid content and volatile organic compound (VOC) content that meets the requirements of national or international standards;
⑦ Compliance with other special requirements.
For examples, fresh water tank coatings are required to be non-toxic and meet the requirements of national health certification; the filterable chlorine content of the coating used for stainless steel surface should not exceed 200 mg/kg, and should be zinc-free; ship ballast tank coatings should meet the requirements of the Performance Standards for Protective Coatings issued by the International Maritime Organization (IMO); coatings below the waterline of the ship are required to prevent the adhesion of marine organisms.
