How to protect the Tin box?
Tin boxesare made of iron. We all know that iron is easy to rust. Rust is a chemical reaction. When tin box products are exposed to the air for a long time, they will oxidize with oxygen to produce rust. In order to prevent the iron box from rusting, we will galvanize and spray paint on the iron material to prevent oxidation and corrosion. This can protect the iron box from acid and alkali corrosion, and protect the contents of the iron box from pollution, in order to effectively prevent When the surface of the iron box is scratched or the paint is scraped off, the scraped area is easy to rust. We can do this.
First of all, we need to know that the damp environment is the easiest to make the tin box rust. When we place the tin box, we should look for a cool and dry place. Iron is chemically unstable and easily reacts with oxygen in the air or water. When we use the tin box, try not to put some sharp objects in it, and do not damage the paint on the surface of the tin box. Do not use excessive force when moving the iron box, so as not to fall to the ground and remove the paint on the surface of the iron box. Finally, a layer of anti-rust or metal curing agent can be applied to the surface of the iron box, which can effectively avoid direct contact between the iron and the air.
If the metal tin box has rusted, you can use a rust remover without scraping off the heavy rust, and then wipe it back and forth with a cloth. After removing the rust, you need to do anti-rust treatment and apply a layer of varnish or a similar paint film.
The rust issue can be handled in the following 3 ways (without experimentation, you can try a small amount first):
1. Use tea leaves to soak the rusty parts of the tea tin can. The reason is simple-the chemical composition of tea contains organic acids such as theanine that can react with rust to achieve the purpose of rust removal.
2 Soak the rusty area of the tea tin can with vinegar for a while, apply clear oil, and it will be healed in a day.
3. Soak in rice water for 50 minutes and wipe with a dry cloth to remove rust.
