Effective measures to protect iron products?

Commonly used methods to prevent rust are:

(1) to change the internal structure of iron. For example, adding chromium, nickel and other metals to ordinary steel to make stainless steel greatly increases the rust resistance of steel.

(2) Covering the surface of iron products with a protective layer is a common and important method to prevent iron products from rusting. According to the composition of the protective layer, it can be divided into the following categories:

A coating mineral oil, paint or fired enamel, plastic spraying, etc. On the surface of iron products. For example, cars and buckets are often painted; Machines are often coated with mineral oil.

B. coat a layer of metal that is not easy to rust, such as zinc, tin, chromium, nickel, etc. On the surface of steel by electroplating and hot plating. All these metals can form a dense oxide film, thus preventing iron products from rusting when contacting water, air and other substances.

C, chemically forming a dense and stable oxide film on the surface of iron products to prevent the iron products from rusting.

(3) Keeping the surface of iron products clean and dry is also a good way to prevent iron products from rusting.

If none of the above can help you, you can try wrapping it in plastic film and see how it works.

I hope the following protective measures will help you:

1. Oil rust prevention. This method is too greasy and polluting, which is not only unsightly, but also has unsatisfactory antirust effect. The antirust effect of dirty oil is lower than that of desiccant and traditional paper packaging, and the cost is higher.

2. Rust-proof paper: Rust-proof paper is an economical and environmentally-friendly rust-proof packaging material, which is used for packaging, transportation and storage of small iron or nonmetal parts; Fast antirust effect and simple use. It has the best moisture-proof, rust-proof and anti-corrosion functions. It also has the characteristics of long anti-rust time, safe use, beautiful packaging and low cost, and is widely used at home and abroad, becoming an indispensable anti-rust material for industrial products and parts packaging, and is very suitable for inter-process anti-rust and storage in mechanical processing industry.

3. Anti-rust film anti-rust: (the function is the same as before)

Paint protection or wax spraying for rust prevention: wax spraying is to spray a layer of wax protective film on the metal surface to isolate the moisture on the metal surface, thus achieving the purpose of rust prevention. This method is simple to use and requires hot water to clean, so it is a safe and environmentally friendly one-time antirust material.

In addition to the above methods, the ironware storage environment should be kept dry and the humidity should not be higher than 50%.
