The Three Major Problems Of Roof Roofing Bolts

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


    When we are doing maintenance on roof bolts, there are three main problems:


    1. When the roof bolts are quenched, the silicate cleaning agent should be used to clean the impurities, and then carefully rinsed to avoid residual impurities on the roof bolts, which affects its normal application.


    2. After the roof bolt is tempered, its color may change. After the roof bolt is soaked in the ether for a certain period of time, oily substance will be produced. This indicates that the roof bolt is not clean enough. After the analysis, it will be found that the stacking of the roof bolts is not very reasonable, and the roof bolts may have some small oxidation in the quenching oil.


    3. If there is a white substance on the roof bolt, it is likely to be 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 rinsing tank.


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