According to statistics, the weight of steel products that cannot be used due to corrosion or rust in the world each year is equivalent to about 10% to 20% of the annual metal production. Metal corrosion can cause increased maintenance and early replacement of machinery and equipment. Corrosion of metal products can reduce the accuracy and sensitivity of the equipment, affect the use of equipment, and even cause the equipment to be scrapped. With the accelerating process of economic globalization, Chinese companies are facing enormous opportunities in both domestic and foreign markets, bringing unprecedented opportunities for development in China's manufacturing equipment industry. However, the problem of metal corrosion has been plaguing product processing and transportation in the manufacturing industry. , storage, etc. The economic losses caused by corrosion are considerable. According to statistics, in 1998, the United States directly lost $137.9 billion due to corrosion; in 1997 Japan caused a loss of 3938.0 billion yen, accounting for 0.77% of the GNP. China’s machinery industry’s losses in terms of rust accounted for about 7.2% of the total value of the machinery industry, and it was estimated at between 500 and 60 billion yuan last year. The direct and indirect losses caused by metal corrosion cannot be ignored. For a long time, in order to avoid corrosion and reduce losses, people have adopted various methods. One of the most common methods is to use anti-rust oil with an oil-soluble corrosion inhibitor to protect metal products.
Antirust Oil Development at Home and Abroad
Anti-rust oil in industrialized countries has developed into a thin layer and an ultra-thin layer. It not only has a good hand feeling and is easy to remove oil film, but also does not affect the appearance of used parts. It can adapt to the needs of large-scale production of steel products and has strong competitiveness. At the same time, it can also develop highly targeted anti-rust products to meet the special needs of users according to different locations.
China's anti-rust oil products have formed a scale, and the annual output has exceeded 20,000 tons. However, the quality and variety of products cannot meet the needs of users. Yan Guofei, Director of Lubrication Marketing at Anmei, pointed out that the main problem with domestic rust prevention products is that the corrosion resistance of rust preventive oil is not ideal during storage of steel products, and the oil layer is too thick, which seriously affects the appearance. After China's “6th Five-Year Plan†and “Seventh Five-Year Plan†researches, there are now a number of rust-proof materials equivalent to the US Army P Series and Japan NP Series, and on this basis, China's own rust-prevention material series has been initially formed. Most of the factories and industries have formulated anti-rust process regulations and rust prevention management systems that are in line with the actual conditions of the industry and the factory, and some are still relatively advanced. And self-made or introduced a number of cleaning, rust, packaging production line. There have been a number of manufacturers of rust-proof technology equipment and can produce test equipment manufacturers that meet the requirements of the standards. In 1988, the National Standardization Technical Committee for Metals and Non-metal Coatings (cs.BTS/TC57) rust prevention sub-committee was set up to uniformly plan and repair and establish standards. Most of the petrochemical and light industrial systems have developed standards for products and test methods, and mechanical systems have been formulated with mostly process and basic standards. At present, domestic rust-proof materials are low, mid-range, and high-grade, and the overall level needs to be improved. From 1989 to 1990, 73 oil samples were evaluated across the country, of which 75% were national standards and benchmarks, and 7.81% were corporate standards, and 17.19% were unqualified products that failed to meet corporate standards. Anti-rust technology development is not balanced, large and medium-sized plant rust prevention technology is generally Lg, 'b plant high, and some local small factories, product production, storage and transportation process without any rust prevention measures. Unbalanced development of the industry, high levels of rust prevention in bearings, tooling, machine tools, automotive and heavy machinery industries, and the introduction or development of a number of advanced anti-rust technology and management methods; and agricultural machinery, general parts, mining machinery and engineering The rust prevention technology of machinery, large plates, coils, strips and other industries is still relatively backward. The research and development of rust-proof packaging technology for large-scale complete sets of equipment has not attracted enough attention. Anti-rust technology equipment compared with advanced industrial countries, the gap is relatively large, mainly reflected in the automation of rust-proof packaging and material quality control automation. The development of automated anti-rust process equipment, rapid and accurate test methods and equipment should be strengthened. At present, 60% to 70% of domestic processes are rust-proof, and 30% to 40% are semi-automatic, which is equivalent to the level of advanced countries in the late 1960s and early 1970s. At present, the United States, Japan, Germany and other countries have developed closed-end computer-controlled automatic line of rust-proof packaging technology and equipment, nearly 90% of single-machine cleaning, drying, anti-dry, rust and packaging. China's product rust-proof packaging technology and equipment, 20% to 30% using a single machine cleaning, degreasing, there is no fully enclosed automated production line. Bearings, measuring tools and the automotive industry have installed and used some automated production lines in recent years, such as the feeding, demagnetization, cleaning, drying, and oiling automation lines of bearings, but the level is quite different from that of advanced countries.
Anti-rust oil development trend
Anti-rust oil has the advantages of good use effect, convenient use, low cost, easy construction, easy operation and easy removal, and has been widely used at home and abroad. With the continuous development of anti-rust technology, the development of anti-rust oil in recent years presents the following trends:
1 Versatility
With the continuous improvement of market requirements, in recent years, there has been a multi-function anti-rust oil on the market, which can adapt to the protection and use requirements of metal products under a variety of conditions. In addition to having a good anti-rust function, it also has other functions and functions, such as lubrication, cleaning, vibration reduction and other effects. The lubricating and rust-preventive dual-purpose oils that have been developed have been widely used in the internal combustion engine and military industry, and can be used directly without removing the film, and the market demand for such rust-proof oils is also growing.
2 thin film thickness
The thickness of anti-rust oil film used in industrialized countries is very thin, and thin and ultra-thin layers of rust preventive oils have appeared successively. The thickness of the oil film can reach several micrometers, the appearance of the used parts is beautiful, and there is no sticky feeling when touched by hand. This will not only save a lot of anti-rust oil, reduce the cost of use, but also play a role in reducing other losses. In China, the oil film of general anti-rust oil can reach more than 20m, not only affects the appearance of the coating, limits the scope of use, but also caused a lot of waste and loss.
3 Low viscosity
When the conditions of use are met, the viscosity of the rust preventive oil should be minimized. Low viscosity and easy coating, and can effectively reduce the thickness of the oil film, can achieve the purpose of saving and reducing damage.
4 Higher environmental requirements
With the increasingly stringent requirements of environmental protection regulations and people’s increased awareness of environmental protection, the requirements for the composition and use of rust preventive oils are also put forward. Therefore, rust-proof materials that meet environmental protection requirements are used to develop biodegradable protection. Rust oil has gradually become the mainstream of antirust oil development.
