During the production, processing, transportation and storage process, it is difficult for metal parts not to come into contact with oxygen, moisture or other corrosive media in the air, and electrochemical corrosion and rust occur on the metal surface. Rust is called the "cancer" of industrial metals, which will bring huge losses to the machining industry, especially the manufacturing and processing of precision parts. Once rust occurs, it will affect the precision and surface roughness of metal parts at the least, and even lead to scrapping and unusability. Rust prevention is a common process for surface treatment of metal parts, which is closely related to ensuring product quality, reducing production costs and improving labor productivity. Therefore, rust prevention is an indispensable part of the metal processing industry. Nowadays, using water-based rust inhibitors for rust prevention is one of the simple and efficient methods.
Water-based rust inhibitors are environmentally friendly products. They are made of high-quality anti-corrosion raw materials and a variety of additives. They can protect the metal surface from erosion by water vapor, air, impurities and other corrosive substances. It is widely used in steel material processing, machinery manufacturing, parts processing and other processes for rust prevention.
How to use water-based rust preventives
Immersion method
Immerse clean metal products in water-based rust preventives. When the rust preventives are fully applied to the metal surface, a protective film will form on the metal surface. Take out the metal and drain it. This method is generally used for rust prevention of large quantities of small metal products and parts, such as bearings, track gauges, cutting tools, hardware parts, standard parts, automobile and agricultural machinery parts, and other small and medium-sized metal parts. Of course, this method can also be used for larger metal workpieces.
Brushing method
Dip the rust preventive with a brush and apply it on the cleaned metal parts. This method is suitable for all products, especially large parts.
Spraying method
During use, spray the rust preventive on the cleaned metal parts through a high-pressure spray device. During the spraying process, select the spray gun according to the viscosity of the rust preventive and adjust the appropriate pressure to make the spray uniform and without intermittent. On the other hand, it is necessary to control the temperature and spray distance to extend in a specific direction to cover the metal surface.
