Although fastener is a small part, it is an indispensable part in mechanical equipment and plays a very important role. Therefore, when we use the fasteners, we need to carry out regular maintenance, so as to ensure the safer use of the fasteners, prolong the service life of the fasteners, and improve the performance of the mechanical equipment.
When we are maintaining the fasteners, what problems often appear? There are three main problems
1. When the fastener is quenched, it is necessary to use silicate cleaning agent to clean the impurities on it, and then rinse it carefully to avoid leaving impurities on the fastener and affecting its normal application.
2. After tempering, the color of the fastener may change. After soaking the fastener in ether for a period of time, there will be oily substances. This indicates that the fastener is not clean enough. After the analysis, it will be found that the stacking is not very reasonable when the fasteners are heated, and the fasteners may have some small oxidation phenomenon in the quenching oil.
3. If there is a white substance on the fastener, it is likely to be some phosphates. The reason for this phenomenon is that the acid cleaner is not used for cleaning and the rinsing tank is not checked carefully enough.
If these problems can not be dealt with in time, it will directly affect the performance of the fastener, and may also lead to the shortening of the service life of the fastener, resulting in the phenomenon of early damage of the fastener. I hope the above three issues can help you make better use of fasteners.
