With the development of my country's national economy, the country has continuously increased its investment in infrastructure construction and accelerated the construction speed. Coatings are facing new requirements. Not only has the infrastructure design begun to develop from reinforced concrete to steel structure, but also new topics have been raised in terms of anti-corrosion protection life, material coating performance, seasonal versatility of materials, and environmental friendliness.
Current status of anti-corrosion coating development
Anti-corrosion coatings are a product that is widely used in modern industry, transportation, energy, marine engineering and other departments. According to the corrosion resistance and use requirements of the coating film layer, it is usually divided into conventional and heavy anti-corrosion types.
Conventional anti-corrosion coatings play an anti-corrosion role on metals under general conditions and protect the service life of non-ferrous metals.
Heavy anti-corrosion coatings refer to a type of anti-corrosion product that can be used in relatively harsh corrosive environments and has a longer protection period compared to conventional anti-corrosion coatings.
01 Products are developing towards multi-function
According to incomplete statistics, there are more than 1.000 varieties of anti-corrosion coatings in my country. A new generation of anti-corrosion coating systems has gradually occupied the mainstream of market research and application. Environmentally friendly anti-corrosion coatings have also been introduced one after another. While enriching the variety, they are gradually developing towards multi-function.
02 Market demand and application scope are broad
Anti-corrosion coatings are widely used. Among them, the chemical and petroleum industries have the largest demand. At the same time, the construction and maintenance of railway and highway bridges are also key areas for the application of anti-corrosion coatings. In addition, the industrial product field and marine anti-corrosion fields such as automobiles and ships are also the largest demand points in the anti-corrosion coating market.
03 Environmentally friendly anti-corrosion coatings have attracted much attention
Anti-corrosion coating companies have eliminated various prohibited coating raw materials and replaced them with more environmentally friendly raw material products to achieve the purpose of energy saving, emission reduction and environmental friendliness of products. I believe that in the next few years, anti-corrosion coatings will still be a hot spot in the market. Domestic anti-corrosion coating companies should continue to strengthen their professional level, provide high-quality products and perfect services, so as to make greater efforts and contributions to China's anti-corrosion market.
Analysis of problems in the development of anti-corrosion coatings
It is understood that the development level of heavy anti-corrosion coatings and the performance of coatings are important indicators of a country's coating science and technology level. With the rapid development of transportation, energy, construction and other industries, the anti-corrosion coating industry has also been further developed, but there are still some problems.
01 There are many manufacturers and small scale
There are many anti-corrosion coating manufacturers in my country. According to incomplete statistics, there are about 700 manufacturers, of which nearly 100 are specialized in producing anti-corrosion coatings, but the scale is not large, and only dozens of them have an annual output of more than 1.000 tons.
02 Market standardization needs to be strengthened
The standards for coating installation in offshore platform anti-corrosion, railway bridges, vehicles, shipbuilding, ship repair and container industries and naval ships are relatively sound, while the sewage treatment systems in the fields of petrochemicals, electronics, food, etc., the industry standards and supporting systems are still being formulated, and some markets have seen disorderly and irregular competition.
03 Research on construction performance and coating technology still needs to be improved
From the concept of coating and coating integration, attention should be paid to coating construction performance. Especially the coating process, surface treatment and supporting system of equipment and facilities maintenance or recoating process should be paid great attention due to different corrosion and construction environments, different damage conditions of the original coating and poor construction conditions.
Anti-corrosion coatings are moving in the direction of high performance, high efficiency, low energy consumption and low pollution. Marine coatings, chemical anti-corrosion coatings, railway, highway bridges and steel structures and other anti-corrosion coatings will remain a hot spot in the market in the next few years.
