What are the causes of tinplate rusting and how to prevent them?
The tin surface of the iron sheet is injured and exposed during the machining process to promote corrosion.Prevention: 1, not coated iron sheet, coated with oil after plating thickening. Effectively prevent water invasion and reduce damage to the process.2 can be painted on the iron sheet of appropriate paint, blocking the impact of corrosive substances.
Attachment of impurities. The impurity is mainly caused by the difference of the impurity with the iron sheet, or the impurity adsorbed the water on the iron sheet to form a galvanic cell.
Invasion of water. The water is on the iron sheet to form a galvanic cell. This should keep the environment dry. Besides, the temperature difference between the iron sheet and the environment should not be too great to avoid the moisture in the air falling out on the sheet iron.
