When the damping nut is pickled, it is necessary to grasp the concentration of the acid, otherwise the acid washing effect will not be obvious. The following is a brief introduction to the daily maintenance of the damping nut:
1, in the quenching of the damping nut, the use of silicate cleaning agent to clean the surface of the attached impurities, and then to be carefully rinsed to prevent residual impurities on the nut, affecting the use of the nut effect.
2. After the damper nut is tempered, its color may change. After the nut is soaked in ether for some time, an oily substance is found, indicating that the nut is not clean. After the inspection, it will be found that when the nut is heated, the stacking is not good enough, and the damping nut may undergo a slight oxidation reaction in the quenching oil.
