Although the fastener is a small part, it is an indispensable part in mechanical equipment and plays a very important role. Therefore, when using fasteners, we need regular maintenance and maintenance, so that the fasteners can be used safely, and the service life of the fasteners is prolonged and the performance of the mechanical equipment is improved.
What problems often arise when we maintain fasteners? In fact, there are three major problems:
1. When quenching the fasteners, use a silicate cleaning agent to clean the impurities. Then carefully rinse them to avoid leaving impurities on the fasteners and affect its normal use.
2. After the fastener is tempered, its color may change. After the fastener is soaked in ether for a period of time, oily substance will be produced. This will indicate the fastener. Not too clean. After the analysis, it will be found that when the fastener is heated, the stacking is unreasonable, and the fastener may have some small oxidation phenomenon in the quenching oil.
3. If there is white matter on the fasteners, it is probably some phosphide. The reason for this phenomenon is that it is not cleaned with an acid cleaner, and it is not careful enough to check the cleaning tank.
If these problems are not handled in time, it will directly affect the use of fasteners, and will also lead to shortened fastener service life and damage to fasteners. I hope that the above three issues can help you make better use of fasteners.
