Dec 12, 2021 View: 946

Although the fastener is a small part, it is an indispensable part of mechanical equipment and also plays a very important role. Therefore, high-strength fasteners remind that when fasteners are used, regular maintenance is required, so as to ensure the safer use of fasteners, extend the service life of fasteners, and improve the performance of mechanical equipment.

When we are maintaining fasteners, what problems often occur? There are three main problems:

1. When the fastener is quenched, use silicate cleaning agent to clean the impurities on it, and then rinse carefully to avoid leaving impurities on the fastener, which will affect its normal application. 

2. After the fastener is tempered, its color may change. After the fastener is soaked in ether for a period of time, oily substances will be produced. The occurrence of such a situation indicates that the fastener Not clean enough. After analysis, it will be found that the stacking of fasteners is not very reasonable when heating the fasteners, and the fasteners may have some slight oxidation in the quenching oil.

3. If there is a white substance on the fastener, it is likely to be some phosphide. The reason for this phenomenon is that the acid washer was not used for cleaning, and the rinsing tank was not carefully checked. 

If these problems cannot be dealt with in time, they will directly affect the performance and use of the fasteners, and may also shorten the service life of the fasteners and cause the phenomenon of early damage to the fasteners.
