Anti-corrosion treatment of metal structures in Moscow and the Moscow region

Anti-corrosion protection of metal structures can be divided into two different classes for solving the problem of emerging corrosion: 1) Corrosion inhibitors (the general name for substances that suppress or delay the course of physiological and physico-chemical corrosion processes), the application of which creates a protective layer of metal structures from corrosion. 2) Protectors - a surface insulated from corrosion is protected by another surface that is more susceptible to an aggressive environment, thereby forming an additional layer subject to corrosion.

This article will look at several options for corrosion inhibitors and protectors , namely anti-corrosion coatings from the AKTERM company.

Why do you need anti-corrosion protection?

Now let’s take a closer look at why anti-corrosion protection is needed. Such protection is especially important for cars. Since the anti-icing additives that are sprinkled on the highway during icy conditions in winter, various defects and scratches resulting from the ingress of pebbles and grains of sand while driving on rural roads significantly reduce the service life of the car. Namely, they will allow rust to penetrate into the metal and corrode it. In such cases, protective coatings are very important.

Corrosion

And steel and cast iron objects lose their sealing properties, thermal conductivity and strength over time without proper anti-corrosion coating. They become completely unsuitable for further work with them. Scientists have estimated that about ten percent of all metal mined on earth is spent on patching holes that appear due to delays in applying anti-corrosion coating. Or no anti-corrosion protection is applied at all.

In addition to domestic accidents, metal corrosion can also provoke environmental disasters. Tons of oil and gas can leak from worn-out pipelines at any time, which will naturally pollute the earth's atmosphere, destroying flora and fauna.

That is why it is so important to cover all metal products with anti-corrosion coatings in a timely manner. Of course, it is impossible to completely avoid the appearance of rust and aging of steel, iron, and cast iron, but this negative impact can be stopped.

In modern times, corrosion control has been divided into several groups that use different rust resistance methods.

Protect products using electrochemistry.
Rust-resistant materials are produced.
Special compounds are introduced into the rusting environment.
Use metal parts and structures correctly, without subjecting them to violent destruction.

Anti-corrosion mastic

Mastic-treated pipes

For this purpose, special means, anti-corrosion materials and methods of applying them to metals were created.

We effectively prevent irreversible changes in the structure of metal structures

Metals, especially ferrous ones, are exposed to aggressive environments during operation. The result of such exposure is corrosion - an irreversible change in the structure of the metal. As a result, there is a loss of strength, load-bearing capacity, integrity, and functional properties.

Main types of corrosion:

liquid. The aggressive factor is moisture. The corrosion process is accelerated by salts contained in sea water and other chemically active substances dissolved in water;
atmospheric. Here, too, the main effect is water, only in the form of vapor. Increased levels of chemically active substances in the atmosphere enhance corrosion;
soil The changes affect foundations and other underground structures. The main aggressive factor is groundwater; the rate of corrosion depends on the composition of the soil.

Types of corrosion also differ in the result, i.e. according to the nature and intensity of damage:

surface – local areas of rust on the surface of the structure;
cracks of different depths;
oxidation of only one of the alloy components;
extensive rust affecting the metal over the entire area and to great depth.

Anti-corrosion varnishes and paints for metal are considered the most durable and easy to use.

Their advantages include:

Simple and quick application;
Simple and inexpensive repairs;
Processing products of any size, shape and design;
Painting at low temperatures;
Work directly on site without the need to transport products to the painting shop;
Wide range of colors;
Long service life;
Cost-effectiveness and safety.

If the composition is applied correctly, substances that provoke corrosion will not penetrate the metal structure. A layer with a thickness of 120-130 microns forms a moisture-proof and elastic film with high strength values.

In the process of anti-corrosion protection, it is important to properly prepare the product for processing. Cleaning is carried out to remove all rust residues, old paint coatings and dirt.

Since anti-corrosion materials have a long service life, you should not skimp on them. A good product costs at least 200 rubles per kilogram. Such varnish and anti-corrosion enamel for metal will not require quick repairs or additional costs.

Examples of anti-corrosion treatment work performed

Causes of destruction of metal surfaces

Anti-corrosion protection of metal structures is a necessary condition for the use of metal elements in any buildings.
Containers, pipelines, and individual parts of mechanisms and vehicles made of metal could last forever, if not for reactions that cause corrosion. Huge steel structures can collapse at some point, causing enormous damage and killing people, if they are not treated with a special compound. Corrosion is caused by:

moisture
atmospheric air
any gas
petroleum products
microorganisms
electrolytes
friction
temperature fluctuation and other factors

This complex interaction process ends in the destruction of the metal. It's difficult to fight him. It's better to prevent a reaction. To do this, you need to apply an anti-corrosion coating, which will create a protective film and protect it from harmful external influences. The result depends on the characteristics of the composition and the quality of its application.

We carry out work in accordance with standards for anti-corrosion treatment of metal structures

When anti-corrosion treatment of metal, we are guided by the requirements of the following documents:

GOST 21.513.83 – features of anti-corrosion protection depending on the functionality of the structure and the presence of aggressive factors;
SNiP 3.04.03-85 and its updated version SP 72.13330.2016 – protection of metal and reinforced concrete building structures from corrosion;
GOST 9.402.2004 and 9.402-80 – preparation of metal surfaces for anti-corrosion painting.

The first part of SNiP/SP is devoted to surface preparation. This is a fundamentally important stage of anti-corrosion treatment: the durability of the protection depends on the quality of preparation. This process includes:

removal of burrs, sagging, welding spatter, cracks, irregularities;
cleaning from rust, dirt, scale, old paint;
degreasing;
removal of active chemicals – alkalis, acids, etc.;
Roughening the surface to improve adhesion.

Surface cleaning methods:

sandblasting;
hydrosandblasting;
shot blasting;
using an abrasive tool;
alkaline;
acidic;
using organic solvents (white spirit, gasoline);
oxidation;
phosphating;
chemical etching;
gas plasma treatment (allowed for metal thickness from 6 mm);
thermal;
ultrasonic;
washes.

GOST also regulates the degree of cleaning, from 1 to 4, depending on the type of anti-corrosion coating.

The joint venture further describes the technology for applying different types of protective coatings:

paint and varnish;
mastic, putty, self-leveling;
based on liquid rubber;
pasting (bitumen, polymer);
gumming;
metallization and combined;
facing and lining.

The final part of the document provides methods for quality control of finished anti-corrosion coatings.

We also offer fire retardant treatment of metal and wooden structures and fire protection of air ducts. Work experience - 10 years. Hundreds of completed projects.

Preparing the metal surface before applying anti-corrosion paint

The service life and anti-corrosion effectiveness of the coating depend on surface preparation

Surface preparation before treatment with primer-enamel 3 in 1 Before applying the coating, if necessary, wash the substrate from oil and grease contamination with solvents or aqueous cleaning solutions; remove dirt and water-soluble substances with clean fresh water. Loose layers of old paint or rust must be cleaned or sanded.

Surface preparation of steel structures is regulated in accordance with ISO 8501-1 to degree Sa 2½. In some cases, upon agreement with the manufacturer's technical service, preparation up to St 2 is possible.

Surface preparation before cold galvanizing Clean the metal from dust and dirt.

Preparing the surface before treating with quick-drying anti-corrosion on water Clean the surface to be treated from loose rust, dirt, dust, oils and old peeling paint.

Surface preparation before resin treatment and isocyanate curing Steel structures: sandblast to degree 2.5. New metal: degreasing with detergents, alkaline etching. Galvanized steel: no adhesion-reducing substances (fats, oils, dust, dirt, zinc corrosion products (white dust), etc.)

Classification of metal anti-corrosion protection methods

There are passive and active anti-corrosion protection. Passive anti-corrosion protection of metal is divided into two classes:

corrosion inhibitors - substances that form a protective layer on the surface of the structure;
protectors are substances that are susceptible to the influence of aggressive environments. An additional covering layer is formed between the medium and the protected structure.

Active anti-corrosion protection technologies:

hot galvanizing – coating the surface with a layer of molten zinc. The method is particularly suitable for the treatment of ships and tanks;
galvanic (electrochemical) galvanizing – a zinc coating is formed during the electrolysis process. Mainly used for small and medium-sized parts;
thermal diffusion galvanizing - surface treatment with zinc powder at high temperatures (290-450 degrees);
aluminizing – aluminum spraying using a ferroaluminum powder mixture;
faoliting (faolite is an acid-resistant plastic coating);
alloying – the alloying alloy contains substances that reduce the chemical activity of the metal;
electrochemical anti-corrosion protection. A sacrificial anode made of metal with strong electronegative properties is connected to the enclosed structure. Polarization reduces the rate of electrochemical corrosion process on the surface of the structure. The method is suitable for protecting pipelines and pile foundations;
deaeration of the environment, reducing its aggressiveness.

The best anti-corrosion agents for internal (hidden) surfaces

The internal parts of the body (the inner surface of the bottom, side members, doors and door pillars) are covered with skin, which complicates the process of applying anticorrosion. Preparations in this group must be highly elastic, neutral with respect to paint, plastic or rubber, have high hydrophobicity and the ability to “preserve” rust.
