My country has successfully developed a variety of industrial anti-corrosion coatings, which play an important role in the anti-corrosion of metal structures. However, so far, the development of heavy anti-corrosion coatings in my country still cannot meet the needs of large-scale engineering construction. High-tech anti-corrosion coatings are far from the actual needs in terms of variety and quality. The problem of short validity period is common. Anti-corrosion coatings with special properties, especially high solids and solvent-free heavy anti-corrosion coatings, cannot meet the long-term anti-corrosion needs of a large number of offshore and coastal facilities, water conservancy projects, petrochemical projects and metallurgical construction projects in my country. It is necessary to strengthen the research and development of protective coating systems with long service life to meet the needs of heavy anti-corrosion coatings for major engineering construction in my country. Severe corrosion under high temperature is difficult for general anti-corrosion coatings to meet the requirements, and the service life is also very short, causing a lot of waste to the industrial economy. Recently, Beijing Zhisheng Weihua Chemical Co., Ltd., located in Dongtieying, Fengtai District, has successively developed and produced ZS-821 ceramic anti-corrosion coatings and ZS-822 composite ceramic high-temperature resistant anti-corrosion coatings. The author understands that these two ZS anti-corrosion coatings are the best in anti-corrosion coatings. ZS anti-corrosion coating materials are made of inorganic nanopowders that have been treated with ultra-high temperature and ultra-high pressure - alumina, boron carbide, rare earth oxides, etc. These powders will form an inorganic spinel single-layer structure after ultra-high temperature and ultra-high pressure treatment. The lattice of the material is repaired, and the synergistic effect of the material's internal anti-corrosion is greatly increased. This ensures that the coating can form a ceramic anti-corrosion coating after being heated at a relatively low temperature. The coating has a dense structure of a cross-linked glass phase, has excellent anti-corrosion effect, high hardness and wear resistance, can withstand corrosion from acidic and alkaline liquids and corrosive gases for a long time, and can even withstand corrosion and friction from strong acids and alkalis.
The author summarizes the advantages of Zhisheng Weihua ZS ceramic anti-corrosion coating compared with other anti-corrosion coatings:
1. High temperature resistance: ZS ceramic anti-corrosion coating has high temperature resistance, and the composite ceramic high temperature resistant anti-corrosion coating can withstand temperatures up to 1400°C, while the maximum temperature resistance of general anti-corrosion coatings is only about 400°C;
2. High hardness: ZS ceramic anti-corrosion coating can form a dense ceramic structure at high temperature, with a hardness of 5-6H, wear resistance and impact resistance, and its hardness is twice as high as that of traditional anti-corrosion coatings;
3. Wide range of acid and alkali resistance: Zhisheng Weihua ceramic anti-corrosion coating can withstand weak acid and alkali corrosion, strong acid and alkali corrosion, waterproof and moisture-proof. Zhisheng ceramic anti-corrosion coating can also prevent acid and alkali gas corrosion, with a wide range of pH resistance, wider application range than traditional anti-corrosion coatings, higher corrosion resistance, and longer service life;
4. Water based environmental protection: ZS ceramic anti-corrosion coatings are all processed from pure inorganic materials, which do not produce any VOCs, are environmentally friendly, do not pollute the environment, and are harmless to human health. They have incomparable environmental protection compared to traditional anti-corrosion coatings/paints.
High temperature reaction vessels in industry are highly corrosive, and the temperature is high, making it difficult for general anti-corrosion coatings to resist. Ceramic anti-corrosion coatings can be used for a long time with good anti-corrosion effects. The irreplaceability of ceramic anti-corrosion coatings. With the development of the economy and the improvement of anti-corrosion requirements, there are higher requirements for the performance of anti-corrosion coatings. The author believes that ceramic anti-corrosion coatings will have broad application prospects.
