Steel ball after buying home to do five points to protect you for many years not rust + kangda steel ball

 

Many clients after the buy back the steel ball steel ball somehow save can not rust, below I give everybody under simple said, because of the bearing steel, carbon steel ball, does not rust, we added a rust-proof oil before they go out, but not with anti-rust oil after everything is all right, never rust, we also need to take some measures, to ensure that steel ball put a decade eight years does not rust.

 

1. Check the packaging: first, check the packaging after receiving the goods to see whether the plastic bags are damaged.

 

2. Sealed preservation: the plastic bag must be tied or sealed, not into the air, otherwise easy to oxidize and rust;

 

3. Attention: try not to touch directly with the hand, especially in summer when there is hand sweat, not to touch directly with the hand, otherwise it is easy to rust;

 

4. Storage place: put in a dry environment, once wet, it is easy to rust;

 

5. Frequent inspection: if not used for a long time, check frequently to see whether the anti-rust oil is less or even dry, and timely supplement of anti-rust oil, otherwise it is easy to produce dry stain or rust;

 

If you can do the above five points, so save a long time not rust is no problem, of course, we hope you quickly use up yo, or give us more orders yo, ha ha!
