Although the rust resistance of the o-ring sealed chain is good, it can not withstand being in a humid environment for a long time, or directly in contact with easily corroded liquids, so the o-ring sealed chain will also appear rust spots. To deal with these rust spots on the o-ring sealed chain, there is a "magic weapon", that is pickling cream.

The use of pickling paste is one of the common methods to remove rust on the surface of o-ring sealed chain. The reason why it is widely favored by users is that the use of pickling paste can greatly improve the finish of the surface of o-ring sealed chain, and then a passivation film is formed on the surface of the chain. It also helps to extend the service life of the o-ring sealed chain.

At present, this method of rust removal using pickling paste has been applied by most o-ring sealed chain users, so most industries such as chemical machinery, food machinery, printing and dyeing machinery, pharmaceutical machinery, pressure vessel manufacturing will be used.

How is pickling paste used in the o-ring sealed chain? It is very simple, first apply the pickling paste on the surface of the o-ring sealed chain, pay attention to the control of the film thickness, try to control between 0.5-2mm, and control the time at more than 3-10 minutes. If the temperature is low in winter, or below 0 ° C or thick oxide skin when used, the time can be extended appropriately.

In this process, it is recommended to scrub the o-ring sealed chain with a brush several times. When the oxidation skin on the surface of the o-ring sealed chain is completely removed, then use clean water. It is also better to wash the o-ring sealed chain with lime water or alkali water, so as to avoid rust. Making the rust removal work more thorough.
