Classification of anti-corrosion coatings

  With the development of China's national economy, the country continues to increase investment in infrastructure construction, accelerating 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. With the development of infrastructure design from reinforced concrete to steel structures, anti-corrosion coatings are facing new requirements, especially in terms of the anti-corrosion protection life of coatings, the coating performance of materials, the seasonal versatility of materials, and environmental friendliness. pose a new challenge.

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

   Today's products are widely used as raw materials in the petroleum industry, coking industry, organic synthesis chemical industry, and other industries, with increasingly higher quality and continuously expanding application scope. How to further accelerate the development of the anti-corrosion coating field, giving it a better position to serve various industries, So, anti-corrosion coatings what are the classifications ?

   Usually divided into conventional anti-corrosion coatings and heavy-duty anti-corrosion coatings, heavy-duty anti-corrosion coatings are essential in paint coatings. Conventional anti-corrosion coatings provide anti-corrosion protection for metals under general conditions and extend 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 anti-corrosion coatings has a longer protection period than conventional anti-corrosion coatings.

   By composition, they can generally be divided into: epoxy anti-corrosion coatings, polyurethane anti-corrosion coatings, inorganic anti-corrosion coatings; epoxy resin anti-corrosion coatings; polyurethane anti-corrosion coatings; polyurethanes, etc. Perchloroethylene, chlorinated rubber anti-corrosion coatings, highly chlorinated polyethylene anti-corrosion coatings;

   According to their use, they can be divided into: pipeline anti-corrosion paint, marine anti-corrosion paint, metal anti-corrosion paint, furniture anti-corrosion paint, furniture anti-corrosion paint, automotive anti-corrosion paint, anti-corrosion paint for rubber;

   According to the solvent, they can be divided into: water-based anti-corrosion coatings, oil-based anti-corrosion coatings;
