Generally, the tinplate box will not rust. At the same time, it is easy to rust only when the inside of the box is wet or placed in a wet place. In addition, rust will occur only when the coating on the outside is damaged; Today, Xiaobian introduces why the tinplate box will not rust;
First of all, the material of tinplate iron box is tinned steel sheet. Due to the different metal properties of iron and tin, the two metals are easy to produce oxidation reaction under natural conditions, resulting in iron sheet corrosion and rust. The iron box packaging is different. The two metals are easy to produce oxidation reaction under natural conditions, resulting in iron sheet corrosion and rust. The finished iron box packaging basically does not need to worry about this problem, because the tinplate will be antirust treated before the iron box is formed. One is that the printing is added with varnish, which not only beautifies the iron box, but also uses the ink used for printing and the varnish on the surface to protect the iron material; The other is a plain iron box, which is not printed and directly polished. The iron is isolated from the air in both ways, which slows down the oxidation of iron in the material.
In addition, when using or storing, pay attention not to put it in a humid environment. At the same time, handle the iron box gently to avoid damaging the paint printing on the surface of the iron box. Secondly, you can wipe the iron box with furniture wax, shoe polish and floor wax at home, and repeat it at intervals. The surface of the iron box is coated with one-time antirust paint or metal curing agent, which can effectively avoid the direct contact between the tinplate and the air.
