Rust spots on the agricultural chain are inevitable. How should we correctly handle the rust spots on the surface of the agricultural chain? Here are some ways to handle the rust spots:
The rust spots on the surface of the agricultural chain can be removed by using acid pickling paste, which can improve the smoothness of the surface of the agricultural chain, form a dense, complete and strong adhesive passivation film on the surface of the agricultural chain, and effectively prolong the service life of the agricultural chain.
The specific operation method is as follows:
Pickling cream is used on the surface of agricultural chains. The thickness of the film is controlled to be 0.5-2mm and the time is controlled to be 3-10min or more. If the temperature is low, or the temperature is lower than 0℃ in winter or the rust is serious, the time can be appropriately prolonged. In this process, it is recommended to scrub the chain several times with a brush until we lay the surface of the chain oxide layer. After this period of time, it is completely removed and then washed with water. Lime or alkaline water can also better wash the chain to avoid rusting.
