Dalian Metal Surface Treatment Company's method for removing rust:

Dalian metal surface treatment, rust is a chemical reaction, and when iron is left for a long time, it will rust. Iron is prone to rust, not only due to its active chemical properties, but also closely related to external conditions. Moisture is one of the substances that makes iron prone to rusting. However, only water will not rust iron. Only when oxygen in the air dissolves in water and reacts with iron in an environment with water will it produce iron oxide, which is called rust.

Rust is a brownish red substance that is not as hard as iron and easily falls off. After a piece of iron completely rusts, its volume can expand by 8 times. If the rust is not removed, the sponge like rust is particularly easy to absorb moisture, and the iron will rust faster. Iron is heavier when it rusts, about 3 to 5 times its original weight.

Dalian metal surface treatment can remove rust by using various tools to shovel it off, or by soaking it in an acidic solution to dissolve it. After removing the rust, the surface of the iron must be treated, coated with a layer of lead, and then painted; Alternatively, it can be plated with other metals that are less prone to rusting.

A more thorough solution is to add some other metals to iron to make a stainless alloy. The stainless steel we are familiar with is an alloy made by adding a little nickel and chromium to the steel. Apply mineral oil, paint, or baked enamel, spray coating, etc. on the surface of iron products. For example, carriages, buckets, etc. are often painted; Machines are often coated with mineral oils, etc. On the surface of steel, a layer of metal that is not easily rusted, such as zinc, tin, chromium, nickel, etc., is plated using electroplating, hot plating, and other methods. These metal surfaces can form a dense oxide film to prevent rust from coming into contact with iron products and substances such as water and air.

Dalian metal surface treatment involves forming alloys to change the internal structure of iron. For example, adding metals such as chromium and nickel to ordinary steel to make stainless steel greatly increases the rust resistance of steel products. Chemical method, clean with an acidic solution diluted to a lower concentration, such as white vinegar, and wipe dry with a cloth after cleaning. Gold and silver jewelry; Simply soak the jewelry in a dilute acid solution for a few minutes, then take it out and treat it with clean water. The jewelry will be as smooth as new.
