Although fastener is a small part, it is an indispensable part in mechanical equipment and plays a very important role
Therefore, high-strength fasteners suggest that regular maintenance is required when using fasteners, so as to ensure the safer use of fasteners, prolong the service life of fasteners and improve the service performance of mechanical equipment
Let's follow the ingenuity Xiaobian and learn it together
 
What problems often occur when we maintain fasteners? There are three major problems:
 
1
When the fastener is quenched, silicate cleaning agent shall be used to clean the impurities on it, and then * washing shall be carried out carefully to avoid leaving impurities on the fastener and affecting its normal application
　
2
After tempering treatment, the color of the fastener may change
After soaking the fastener in ether for a period of time, oily substances will be produced
Such a situation indicates that the fastener is not clean enough
After analysis, it will be found that the stacking of fasteners during heating is not very reasonable, and there may be some small oxidation phenomena of fasteners in quenching oil

3
If there is white substance on the fastener, it is likely to be some phosphide
The reason for this phenomenon is that the acid cleaning machine is not used for cleaning, and yo ah, the inspection of * washing tank is not careful enough
　
If these problems cannot be handled in time, they will directly affect the performance and use of fasteners, and may also shorten the service life of fasteners and cause early damage of fasteners
