The tinplate box is generally not easy to rust, but the inside of the iron box is wet or placed in a humid place to rust easily, and the outer plating is destroyed to cause rust.
The tinplate is made of tin-plated steel. Due to the different metallic properties of iron and tin, the two metals are prone to oxidation under natural conditions, causing corrosion and rusting of the iron. The iron box packaging that is done well does not need to worry about this problem, because the tinplate is rust-proofed before the iron box is molded. One is printing plus varnish, which not only beautifies the iron box, but also uses the printing. The varnish of the ink and the surface layer is double-layered for the iron material; the other is the plain iron box, which is not printed directly through the varnish. In both ways, the iron material is in good contact with the moisture in the air, which slows the oxidation rate of the iron.
How can the tinplate be protected from the rusting "destiny"?
1. We should not place the iron box in a damp environment. At the same time, we should gently handle the iron box to avoid damaging the paint on the surface of the iron box.
2, we can use the home furniture wax, shoe polish, floor wax, wipe the iron box, repeat every time interval.
3. We can apply an anti-rust paint or metal curing agent on the surface of the iron box to effectively avoid direct contact between the tinplate and the air.
