Maintenance of fasteners requires attention

Although the fasteners are small, they have a great effect. The use of fasteners requires regular maintenance to ensure safer use of the fasteners, and can extend the service life of the fasteners and improve the performance of the mechanical equipment.

When we are maintaining fasteners, there are three main problems:

1. When the fastener is quenched, the silicate cleaning agent should be used to clean the impurities, and then the rinsing should be carefully carried out to avoid the residual impurities on the fastener, which affects its normal application.

2. After the fastener is tempered, its color may change. After the fastener is soaked in the ether for a period of time, oily substance will be produced. When this happens, the fastener is indicated. Not clean enough. After the analysis, it will be found that the stacking is not very reasonable when heating the fasteners, and the fasteners may have some small 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 there is no cleaning with an acid cleaner, and it is not careful enough to check the rinsing tank.

The above problems must be taken seriously, which will directly affect the performance of the fasteners, and may also lead to shortened service life of the fasteners, resulting in early damage of the fasteners.
