The causes of engine corrosion in various environments are related to the design of the material and the anti-corrosion structure on the one hand, and the anti-rust quality by the manufacturing process level and maintenance. As can be seen from the manufacturing process of the engine, the anti-rust protection process is an important process throughout. The application of anti-rust technology prevents the metal parts of the engine from rusting during the production process to ensure the assembly quality and service life of the car.
According to the structure, the engine can be divided into two parts: rust prevention of parts and rust prevention of the whole machine; according to the production process sequence, it can be mainly divided into three parts: anti-rust between processes, anti-rust during transportation and anti-rust.
There are also various methods for preventing rust. Commonly used metal rust prevention methods include paint, rust preventive oil, rust preventive liquid, vacuum packaging, and gas phase rust prevention. So how to find a way to suit your actual situation in so many anti-rust methods is not very easy to work.
Shenyang Anti-rust Packaging Materials Co., Ltd. has accumulated rich experience in the field of anti-rust of automobile engines, and has done many successful cases. It is here to share with you and hope to bring you some inspiration.
In 2005, an engine factory in Shenyang.
The factory mainly produces 4G6, 4A9 series engines, with an annual production capacity of 400,000 units, supporting more than 20 domestic automakers. The engine has been exported to the United States, Italy, Egypt, Australia and other international markets with the whole vehicle, and the quality is highly recognized by the international market.
However, it is such a factory that has experienced serious corrosion problems, which has affected the company's reputation. After learning about the rust prevention in Shenyang, the technicians were sent to the site for investigation and analysis. It was finally found that the residual water in the cooling system was the main cause of corrosion. Originally, the engine before the factory was hot-tested using tap water to cool, and the water remaining in the water channel often could not be drained, resulting in serious corrosion of the product at the customer. After scientific analysis and trial and error, Shenyang anti-rust proposed a solution to inject water-based anti-rust solution after the test. The water-based anti-rust liquid refers to a rust preventive agent which can be diluted with water during use, and the main component thereof is composed of a water-soluble anti-rust compound, a water-soluble auxiliary agent, a solvent and water, and the metal workpiece using the product enters and enters No need to clean before a process or simply clean, greatly simplifying the process. The water-based anti-rust solution completely solved the rust problem of the cooling system of Shenyang Engine Manufacturing Co., Ltd.
