The rust converter in the farm

Rust is called iron oxide. The appearance of rust is a sign that the metal came into contact with either oxygen or water. The surface of pure iron is usually neutral to such influences, only a metal having certain impurities-carbon, sulfur, phosphorus, etc., is oxidized. Sulfur dioxide and carbon dioxide contained in water can also exert an oxidizing effect.

The danger of rust is that it slowly corrodes the product of steel or cast iron, gradually changing its shape and volume. Oxidation of iron plays an extremely destructive role.

In many cases, to avoid the appearance of rust, the part is coated with a special coating, in particular, chromium oxide is used for this . But what if the oxidation of the iron alloy has already begun?

In this case, the rust converter can help. It not only eliminates Oxidation, gradually eroding metal, but also creates a strong protective film of oxidation products. In general, the rust converter is used to protect from corrosion structures made of carbon or low-alloy steels. In this case, the layer of iron oxide should not be more than 100 μm. The rust converter is often made of phosphoric acid, as well as hydroxycarboxylic acid, tannin and even cement. It can be purchased in the form of an emulsion, solution or suspension.

Different types of this tool operate in different ways. Conditionally they are divided into several main groups: the rust converter in the ground for paintwork; Stabilizers of corrosion products that convert metal oxide hydrates to more stable chemical compounds; Converters of corrosion products, turning rust into poorly soluble salts; Special penetration formulations that have the property of compacting corrosion products.

In the choice of the method of applying the agent to the surface, the viscosity of a particular agent plays a major role. Depending on its consistency, the rust converter is applied by jetting, dipping, brushing or spraying. Before coating the surface of the metal with the appropriate composition, it is necessary to prepare it. It is necessary to clean the formation corrosion products and loose layers of rust.

Converters are contraindicated for use in cases where oxidation was caused by an atmosphere containing an increased amount of ammonia, hydrogen sulphide or sulfur dioxide.

If rust has covered any parts of your car, it is worth using a special kind of rust converter in the ground. They eliminate the old layer of corrosion and prevent the formation of a new layer. The agent can change the color of the surface depending on the type of corrosion. First, prepare the part - remove dirt and lubricants if they are present. Remove the corrosion products with a metal brush. Then rinse off the surface of the residue of contamination. Shake the rust converter before use. The composition is applied to the prepared surface.
