I don't know if you have noticed the small part on the bag we use in daily life - bag screw. Leather screws are also prone to rust after being used for a long time. What is the cause of rust? Let us take you to understand:
1. The electroplating factory did not dry the screws in the case of electroplating, resulting in the retention of water vapor, or the formation of condensed water in the packaging after drying, resulting in chemical reaction and bad occurrence, resulting in the rust of the screws in the case;
2. If it is stored in a damp place for a long time, the bag screws will be slowly corroded and oxidized, resulting in rust of the screws;
3. Poor electroplating and too thin electroplating of screws will also lead to rust;
Methods to deal with rust of bag screws: 1. In the storage environment, the bag screws must be put in a suitable environment, should not be too wet, should be ventilated, ventilation. There should be a stand to hold the bag screws away from the ground. 2. In terms of the type of electroplating, the electroplating color with longer salt spray test time should be selected. When electroplating, electroplating should be good, the electroplating layer should not be too thin.
