Classification of anti-corrosion coatings

With the development of my country's national economy, the state has continuously increased its investment in infrastructure construction and accelerated the pace of construction. In this process, the construction of infrastructure has also driven the development of a series of industries, and promoted the continuous progress and upgrading of various technologies. As infrastructure designs evolve from reinforced concrete to steel structures, anti-corrosion coatings face new requirements, especially in terms of the anti-corrosion protection life of coatings, coating performance of materials, seasonal versatility of materials and environmental friendliness. Come up with a new topic.

According to the data of the "China Corrosion Investigation Report", the annual loss caused by the corrosion of metal materials in my country alone is as high as 500 billion yuan, accounting for about 5% of the gross national product! Among them, the oil and gas system is about 10 billion yuan, the coal industry is about 5.5 billion yuan, and the power system is about 1.6 billion yuan. However, the total industrial output value of the entire coatings industry minus raw materials is only half of it. It can be seen that there is a lot of space for anti-corrosion coatings.

Today's products have been widely used in the petroleum industry, coking industry, organic synthetic chemical industry and other industries, as raw materials, their quality is getting higher and higher, and the scope of application is expanding. How to further accelerate the development of the field of anti-corrosion coatings, make it have a better position and serve all walks of life, then what are the classifications of anti-corrosion coatings?

Usually divided into conventional anti-corrosion coatings and heavy-duty anti-corrosion coatings, heavy-duty anti-corrosion coatings are essential coatings in paint coatings. Conventional anti-corrosion coatings protect metals under normal conditions and protect the life of non-ferrous metals. Compared with conventional anti-corrosion coatings, heavy-duty anti-corrosion coatings can be used in relatively harsh corrosive environments and have the capability of class A anti-corrosion coatings, which have a longer protection period than conventional anti-corrosion coatings.

According to the composition, it can be generally divided into: epoxy anti-corrosion coating, polyurethane anti-corrosion coating, inorganic anti-corrosion coating; epoxy resin anti-corrosion coating; polyurethane anti-corrosion coating; polyurethane and so on. Perchloroethylene, chlorinated rubber anti-corrosion coatings, high chlorinated polyethylene anti-corrosion coatings;

According to the use, it can be divided into: pipeline anti-corrosion paint, ship anti-corrosion paint, metal anti-corrosion paint, furniture anti-corrosion paint, furniture anti-corrosion paint, automobile anti-corrosion paint, anti-corrosion paint for rubber;

According to the different solvents, it can be divided into: water-based anti-corrosion coatings, oil-based anti-corrosion coatings;
