Heavy-duty anti-corrosion coating: refers to a type of anti-corrosion coating that can be applied in a relatively harsh corrosive environment compared with conventional anti-corrosion coatings and has a longer protection period than conventional anti-corrosion coatings.

　　 Features of heavy-duty anticorrosive coatings:

  ①It can be used under harsh conditions and has a long-lasting anti-corrosion life. Heavy-duty anti-corrosion coatings can generally be used for 10 or 15 years in the chemical atmosphere and marine environment, even in acid, alkali, salt and solvent media, and Under a certain temperature, it can be used for more than 5 years.

　　②Thick film is an important sign of heavy-duty anti-corrosion coatings. Generally, the dry film thickness of anti-corrosion coatings is about 100μm or 150μm, while the dry film thickness of heavy-duty anti-corrosion coatings is 200μm or more than 300μm, and there are 500μm-1000μm, even as high as 2000μm.

　　The main application areas of heavy-duty anti-corrosion coatings:

　　①Emerging ocean engineering: offshore measures, coastal and gulf structures, offshore oil platforms;

　　②Modern transportation: highway guardrails, bridges, boats, containers, trains and railway measures, automobiles, airport measures;

　　③Energy industry: hydraulic equipment, water tanks, petroleum refining equipment, petroleum storage equipment (oil pipes, oil tanks), power transmission and transformation equipment, nuclear power, coal mines;

　　④Large industrial enterprises: papermaking equipment, medical equipment, food chemical equipment, inner and outer walls of metal containers, pipelines of chemical, steel, petrochemical plants, storage tanks, mining and smelting, cement plant equipment, floors with corrosive media, cement components for walls;

　　⑤Municipal measures: gas pipelines and measures (such as gas tanks), natural gas pipelines, drinking water measures, garbage disposal equipment, etc.
