TO FIND THE OPTIMUM REGIME

Question: What does present by itself the corrosion of metals?

Answer: Corrosion (from Lat. corrodere - to corrode) is called the spontaneous destruction of metals and their alloys under the effect of the environment. The clear example to corrosion - rust beyond the surface of steel and cast iron articles. Yearly because of the corrosion are lost about fourth of all produced in the world iron. Expenditures for repair or replacement of vessels, automobiles, instruments and communications, water pipes many times exceed the cost of the metal, based on which they are prepared. Corrosion causes the serious ecological consequences: its products cause environmental pollution, negatively they act on life and health of people.

Question: What there are methods of preparing the incorrodable metals?

Answer: The basic methods include: the alloying of metals, heat treatment and other

Question: Which the technology of the alloying of metals?

Answer: The transfer of metal from the active mode beside the passive is reached as far as alloying. In this case inert film with the high shielding properties is formed. For example, the alloying of iron for the sake of chromium makes it possible to convert iron to steady passive state and to create the entire class of the alloys, called the stainless steel. The additional alloying of the stainless steel for the sake of molybdenum removes their tendency down to the pitting corrosion due to the conditions of applying the material before the moist medium. The alloying of titanium for the sake of a small quantity of palladium sharply increases corrosion resistance before the aggressive slightly oxidizing media. By alloying is achieved also the protection of steels and alloys from the microcorrosion.

Question: What does occur with the metal as a result of heat working?

Answer: This method removes the structural heterogeneity, which causes selective corrosion. Internal voltages before the alloys as a result are removed, excluding thus their tendency down to the intercrystalline and pitting corrosion, and also to the stress corrosion.

Question: How is carried out the burnishing of steel articles?

Answer: They thoroughly grind and polish article. Its surface is degreased by washing before the alkalis, after which they warm thoroughly to 60-70°[S]. then they place beside the furnace they heat to 320-325°[S]. the flat painting of surface it is obtained only with the uniform warming up. Processed thus article wipe by hemp-seed oil. Again slightly they warm thoroughly and wipe dry after its lubricant.

After burnishing steel acquires the black or dark blue painting of different nuances, it preserves metallic luster, and beyond its surface is formed the steadfast oxide film, anticorrosive.

Question: How is produced the bluing of steel components?

Answer: For this they compose 2 solutions: 140 g of hyposulfite on 1 l of water and 35 g of acetous lead (“sugar of lead”) also on 1 l of water. Before the use they mix up and heat solutions before the boiling. Articles preliminarily clean, they polish to the luster, after which immerse before the boiling liquid and they hold until the desired color is obtained. Then component washes before the hot water, is dried and is rubbed by castor or clean machine oil. The components, processed thus, little down attackable.

Question: How is achieved “through protection” of metal?

Answer: In the sections with the damaged zincplating (anode) protects steel (cathode), ensuring cathode protection. This is so-called “through protection”, inherent only to active coatings. The period of the action of cathode protection depends on the thickness of the layer of zinc, damage remained on the spot.

Question: Before what the essence of the barrier protection of metal from the corrosion?

Answer: Barrier protection - is the mechanical isolation of the surface of metal. Its effectiveness depends beyond the degree of impenetrability (porosity), chemical stability of coatings, degree of the cohesion (adhesion) of paint with the protected surface and on the rapidity of the appearance of microscopic cracks before the coating. Method relates down the discharge traditional and least effective.

Question: What does present by itself the passivation of metal?

Answer: The passivation of metal with the aid of the varnish-and-paint means is achieved by the chemical interaction of the protected surface and components of coating. This group of materials includes ground and enamels, which contain the phosphoric acid (parkerizing), and also compositions with the inhibiting pigments, which retard or which prevent the process of corrosion.

Question: How is carried out the protector protection of metals?

Answer: Protector protection is achieved as far as addition down the material of coating the powders of more steadfast to the corrosion metals than protected. These are zinc, magnesium, aluminum for iron. Under the action of aggressive medium the dissolution of powder- additive occurs, but the protected metal is preserved and does not corrode.

Question: What such is deaeration?

Answer: The presence in water of oxygen and aggressive anions, especially chlorions, sharply reduces the life of thermal networks. The values of critical metal potentials change due to the deaeration and the water treatment. This increases corrosion resistance.

Question: Why it is not possible to remove patina based on the surface of copper?

Answer: Those removing patina assume that the copper (bronze) articles so are cleaned and renew. But they make mistakes. Patina beyond the surface of copper prevents its further corrosion. For this reason it is not possible to polish bronze monuments and ancient statuettes to the luster. Tolstoy, 3-6- millimeter forged sheets of roofing copper, which used a master before the antiquity, possess high weather resistance. Record holder is, apparently, the copper roof of cathedral before [Khildeskhayme] in lower Saxony (Germany), to which already 700 years. The decorative properties of patina push producers of roofing copper, and also people, which carry out decorative metal working, for the improvement of the methods of the accelerated formation of patina. It already lets out the number of firms and realizes the artificially aged copper roofing sheet.

INHIBITERS WILL LOWER THE LOAD

Question: What such the inhibiters of corrosion?

Answer: These are - the substances, which retard the corrosion of the metals (from the Latin “[ingibeo]” - I stop, I hold in control). The inhibiters of acid corrosion were known even before the middle ages. Master- gunsmiths with the etching of steel models for removing based on them the slag added beside the acids flour, bran, yeast(s).

Apparently, the first patent in the field of application of an inhibiter was given out to Englishman to Baldwin, who proposed the mixture of treacle and vegetable oil as the additive with the etching of sheet iron before the acids. In 1907 [CH].[E]. To [laverti] and [A].[F]. To [laverti] proposed for this purpose hydrocarbons, in particular resin and oils. In 1928 in our country work on the creation of synthetic inhibiters began.

Question: What there are varieties of inhibiters?

Answer: The inhibiters of acid corrosion adapt with the acidic etching and cleaning of the surface of metalware, for increasing the effectiveness of chemical-battery power supplies, for the protection of equipment and conduits. Are used the cathodic or mixed inhibiters of corrosion, which substantially retard the isolation of hydrogen.

Inhibiters for the neutral media protect different cooling systems and industrial water supply, they prevent the corrosion of metalware during the storage.

The inhibiters of the alkaline corrosion are used with the alkaline the working of amphoteric metal before the washing compositions, for decreasing the self-discharge of alkaline chemical-battery power supplies, for the protection of evaporating equipment.

Question: Are such the properties of the inhibiter of corrosion MOK -5?

Answer: Preparation adapts with the etching of articles through carbon, alloy and transformer steel before the mineral and organic acids, for the protection of gas and petroleum industry equipment, with the acidic washings of diesel equipment, as the additive to the lubricating cooling liquids and during the conservation of production from the ferrous metals.

They relate to the major advantages of inhibiter MOK -5 over analogs:

• low concentration;
• high efficiency with the protection of metal;
• the absence of influence beyond the rate of dissolution of slag;
• stability to the accumulation before the etching bath of iron salts;
• the content of foaming agent;
• ecological safety;
• the canning aftereffect;
• averting carbonate deposits before the heat-power engineering equipment and the communications;
• a good solubility before the aqueous medium.

Question: What is the inhibiter of the corrosion of system “protector”?

Answer: It is known, how many troubles reach rusting the internal walls of the pipes of the hot-water heating. In order to avoid them, specialists recommend the adding of this inhibiter of corrosion beside the water. Preparation reliably protects the pipes of heating system (heating elements, conduits, radiators, expansion tanks and others) from the rust. If heating outline old, “protector” thoroughly washes it from within, having completely freed based on slag and mud.

Question: What merits does possess the preparation “Of [tektil]”?

Answer: Judge themselves, in the first place, he it contains the inhibiter of corrosion, which localizes rust, it does not give to it to be developed, which makes it possible to bring preparation down the already corroded surfaces. In the second place, reliably it couples with the metals even before the process of the work of aggregate, since it possesses the penetration ability to, i.e., penetrate as far as property the microscopic cracks, simultaneously displacing moisture and “involving” wound. This effect is provide ford for the sake of the use of a special filler, which composes the know-how of firm Valvoline.

DO NOT FORGET TO COLOR

Question: What materials most frequently do adapt for the corrosion protection?

Answer: For any metal constructions and conditions for their operation the simplest and accessible method of corrosion protection is the application of special paints on the metal. Paint and varnish coats have a number of advantages in comparison with other types of the protective coatings:

• simplicity of putting;
• the possibility of obtaining coating any color;
• the possibility of treating the metal structures of large overall sizes and complex configuration;
• cheapness in comparison with other types of protective coatings;
• they are economical, they possess high shielding properties, it is possible to restore them before the process of operation.

Increasingly more are extended the plastic coatings from polyethylene, polyisobutylene, polyfluoroethylene resin, nylon, polyvinyl chloride and other, which possess high water, acid- and by alkali resistance. Many plastics use as lining material for the chemical apparatuses and the plating baths (polyvinyl chloride plastic, faolite and other). Effectively they protect from the action of acids and other reagents of coating on the basis of natural rubber (rubberizing). Underground structures, for example conduits, protect from the corrosion by bitumens and asphalts, and also by polymeric tapes and enamels; from the moisture - with the aid of the drainage, which removes them from the construction.

Question: What materials are capable of reliably protecting from the corrosion iron roofing?

Answer: Specialists recommend to use ultra-deKs-01, which is characterized by high wear resistance, convenience in the putting (by usual brush or by roller), stability to the action of aggressive media (acidic rains, rust), resistance to ultraviolet irradiation. Also good itself recommended the preparation Of [urefleks]-03, which in contrast to the first is two-component coating and hardens practically instantly. By the way, to work with it is possible and at a minus temperature of air.

Question: Before what the special feature of the application of protective coatings on the technology HVLP?

Answer: Technology HVLP - this is the cloudless dispersion of paint, reached by the pressure regulation of air against different stages of the passage of paint. It is possible to attain by a change in the balance between the high and low pressure the very precise dispersion (because of a decrease in the velocity of the pulverized particles of the paint). Furthermore, this construction gives the possibility to change the size of torch from 10 to 300 mm, which makes it possible to form uniform layer with the high accuracy. The brightest representatives of the new family of injecting pistols are models GTI and GFP.

Because of the new air cap was obtained the technology Of trans-Tech, which helped to attain:

• the high quality of spraying;
• obtaining the desired color, before the precise correspondence for the sake of the tone of the selected paints;
• the savings of material;
• the very insignificant flow rate of air (only 280 l/min) with the inlet pressure of 2 bar;
• tuning the size of torch for any materials.

Question: Before what the advantage of coloring pistol GFP?

Answer: Before the pistol GFP is used remarkable innovation - separate construction of air-distributing ring and sprayer for the paint. Moreover, with a change in the diameter of sprayer 1,6 - 1,8 - 2,2 - 2,5 mm is not required the replacements of needle. Specialists will estimate the benefit of know-how with the change of the viscosity of the utilized material (ground, paint, varnish). But this is far from all merits of this equipment. Among other advantages it is necessary to note application in the construction:

• the high-strength alloys of the stainless steel and special polymeric materials;
• information to the minimum of a quantity of friction components;
• the high-precision machining of metallic components, on which enter paint and air.

Question: Why it is necessary to tincture structures from the unstainable metals?

Answer: Before the building increasingly more frequently adapt the metal structures through the galvanized iron, stainless steel, aluminum and even copper and other nonferrous metals, immune down corrosion. And does arise logical question - it is necessary whether to tincture similar constructions? Answer will be single-valued: “It is without fail must”. In this case the dual purpose is pursued. The first, galvanized iron, aluminum and copper, assume that and on much smaller scales, than usual steel, but nevertheless the attackable. Therefore them must be additionally protected by anticorrosive coating. In the second place, not colored metal is not always entered before the architectural or design solution of object. Consequently, metallic surfaces need decorative painting in order to give the final form to finished structure.

Question: What such “of poly-Line”?

Answer: Closegrained coatings for the floor and the walls “of poly-Line” - these are the single-component compositions, used for the protection of the majority of the types of structural bases. High chemical stability, convenience in the putting and wide universality of application make it possible to solve the problem of the anticorrosive protection of metal structures and concrete. They increase wear resistance and resistance to the action of aggressive media.

Exterior view - uniform glossy film

Surfaces for the putting - metallic surfaces, the concrete

Method of putting - short-haired roller, the brush

Theoretical - 0,3 (down 2 layers) expenditure ([kg]/[m]2)

Time of drying (hours) 3

Full mechanical load - in 2 days

Stability to the aggressive media - in 7 days

Question: Before painting of the zinc-coated surfaces and surfaces from the nonferrous metals there are its finesses. What they?

Answer: First of all, it is necessary to remember about the special features of surface preparation before the painting. It is not possible to subject such metals down usual shot peening, since it disrupts their natural corrosion resistance. The surfaces of this type process with the aid of the special abrasive agent - round particles of the glass, which do not destroy the protective layer of zinc beyond the surface. It is sometimes sufficiently simply working as far as the solution of ammonia for the removal of grease stains and products of the corrosion of zinc based on the surface.

Question: Name any ground, which can be brought directly down the rust?

Answer: Will approach [Nerzhamet]- ground, saturated by the inhibiters of corrosion. It ensures excellent basis for putting the antifouling paints. The life of paint considerably prolongs. It is brought directly down the rust. It works beyond the surface of metal as the converter of rust, connecting it chemically, and resultant polymer film it reliably insulates the surface of metal from the actions of aggressive medium.

Question: When is used the enamel of [Nerzhamet]- luxes?

Answer: This is anticorrosive enamel for the nonferrous metals with the excellent characteristics on the weather resistance. It is intended for the dyeing both of clean and rusty or partially corroded metallic surfaces. Has outstanding characteristics on the frost resistance, stability to the abrasion and the impact actions. Product combines before itself the properties of the converter of rust, anticorrosive ground and decorative enamel, which makes it possible to considerably simplify the process of dyeing. It can be brought directly down the rust, it extremely rapidly dries in air.

Question: Is whether the means, which simultaneously protect metal, concrete, and brick so forth?

Answer: There is. Paint on the rust “Of [fankor]” can be used for the surface protection both of the ferrous metal and the concrete, the brick, the slate, the tree. It also can be brought down the durable layer of rust without its removal. During the damage of coating the rust is formed only beyond the surface not protected by paint, without being extended under the film. It possesses very high hydrostability.

“Marion's enamel” on the basis of chlorosulfonyl polyethylene can be brought down the constructions, which have metallic, and concrete surfaces.

Question: Are such the exemplary periods of the corrosion protection of various varnish-and-paint compositions?

Answer: The widely utilized varnish-and-paint systems (consisting of 2-5 layers paints) have periods of anticorrosive protection - 4-10 years. The hot galvanizing of steel constructions ensures the periods of the operation of 10-50 years.

CONVERTER OF THE RUST

Question: How to clean rust from surfaces of metals before the painting?

Answer: “by Ron- stop”. These are the gelatinous solution of polyfunctional connection, intended for cleaning of the surface of metals from oxides, slag, scale deposit. Preparation is highly technological product of domestic defense industry.

Question: As to separate the [prirzhavevshie] components: nut, drivings, the clutch of pipes?

Answer: There is the means, to which the authors gave very expressive name - “auto-ThomasKA”. (As is known, [fomka] - this is the tool, with the aid of which are broken open the safes, iron doors and the like). Here and with the aid of the technological collection “auto-ThomasKA”, which consists besides the emulsion solution and the measuring hopper, it is easy to separate not only the [prirzhavevshie] threaded connections of pipes and drivings, but also the [prikipevshie] (and burnt) metallic parts of the most varied engines, electromotors, pumps.

Question: How to remove rust based on the window latches, the loops of the forged fences?

Answer: Rust to most simply remove by the diluted aqueous solution of hydrochloric or sulfuric acid, which contains the inhibiter of acid corrosion Urotropin. This substance impedes the chemical reaction (in this case the reaction of the dissolution of metal before the acid), but it does not prevent interaction of acid with oxide and hydroxide of iron, of which consists the rust. If rusted window latches, components of lawn mower, bolts and nuts of water pumps and the rest, they are immersed before 5%- ache the solution of acid for the sake of the addition 0,5 g of Urotropin down the liter, down the large things the solution is brought by brush.

To use solutions of strong acids without the inhibiter [riskovanno]: it is possible to dissolve not only rust, but also article itself, since iron - reactive metal interacts with the strong acids with the isolation of hydrogen and the formation of salts.

As the inhibiter of acid corrosion with the removal of rust it is possible to use, for example, a potato vegetable tops. Fresh or dried leaves of potatoes place for this beside the glass jar and 5-7%- noy pours for the sake of sulfuric or hydrochloric acid so that acid level would be above the flattened vegetable tops. After the 15-20-minute mixing of contents it is possible to pour acid and to use banks for working of rusty iron articles.

Question: What such is “the converter of rust”?

Answer: This 15-30%- ache the aqueous solution of orthophosphoric (usual phosphoric) acid. It converts rust beyond the surface of metal beside the durable coating of brown color. It adapts as follows. Down the struck by corrosion article by brush or by pulverizer brings “the converter of rust” and they give to dry in air. It is still better to use an orthophosphoric acid with the additives, for example, 4 ml of butyl alcohol or 15 g of tartaric acid on 1 l of the solution of orthophosphoric acid. Orthophosphoric acid transfers the components of rust beside orthophosphate of iron Of fePO4, which creates beyond the surface protective film. Simultaneously tartaric acid the connecting piece of the derivatives of iron beside the tartrate complexes.

Question: How to protect from the rust tools?

Answer: For this joiner or fitters tools are lubricated with the aid of the brush by the solution 10 g of wax before 20 ml of gasoline. Wax is dissolved before the gasoline on the water bath, without using the free flame. They protect the polished tool, bringing down its surface the solution 5 g of paraffin before 15 ml of kerosene. There is the ancient prescription of ointment for the protection of metal from the rust. It is lit by 100 g of lard, is added by 1,5 g of camphor, they remove based on the fusion foam and mix up with graphite, ground beside the powder so that the composition would become black. They lubricate tool by the cooled ointment and leave on day, after which is polished metal by woolen rag.

Question: What to make, in order to the nut not of [prirzhaveli] to the bolts?

Answer: In order in the future not to suffer, turning away fasteners with the rusted thread, they previously lubricate them by the mixture of vaseline for the sake of the graphite powder. Instead of vaseline it is possible to take any other fatty lubricant of neutral or weak-alkaline type. Bolts and nuts on this lubricant easily turn away even through several years of a stay under the open sky.

WATER REMOVAL WITHOUT THE PROBLEMS

Question: How to bring protective coating, if the surface of metal is moist?

Answer: One of the serious problems, which encounter the users with the application of paint and varnish coats, is the moisture from the remainders of old paint remained before the times of metal. During the application of traditional paint and varnish coats forming on top the film preserves and retains this moisture. Problem successfully solve single-component polyurethanes, in particular, priming “urethan -[Antikor]”. In contrast to the traditional paint and varnish coats polyurethanes harden due to the reaction for the sake of the atmospheric moisture. As a result is formed the monolithic integral film, solidly connected for the sake of the surface and which penetrates beside the times of metal. Furthermore, because of interaction of components “urethan -[Antikora]” with the moisture, which is contained before air, before the times of metal does not appear internal stress, in consequence of which during the sequential freezings coating will not swell.

Question: How to protect the surface of iron roofing from the moisture?

Answer: Organosilicate composition has the increased adhesion to the metal and forms beyond the surface of the metal structures painted for the sake of it the protective coating, which possesses the antifreeze, water-repellent, anticorrosive and heat-frost-hardy properties. The technology of putting composition does not differ from the methods of putting the usual paints and is convenient fact that, in contrast to the majority [LKM], it is possible to work at temperatures to -20°[S].

Question: What by itself is “OF WD-40” and as it was created?

Answer: Everything began based on the trick of the millionaire of Howard Hughes. In 1952 it ordered to firm “General Dynamics” several jet liners, and when order was executed, Hughes suddenly forewent them. Thus far two firms argued with each other, the aircraft, which stood beyond the runway of airfield, began to be covered for the sake of rust. Before “General Dynamics” they were alarmed: it is necessary urgently something to make so that the apparatuses would not be pulled down. The specialists of firm turned themselves down the company “It [roket] [Kemiklz]”, which specialized before the lubricants for aviation engineering. The President and the chief chemist of company Norman Larsen began to develop the composition of substance, which will be able to remove rust. After the fortieth attempt it composed the lubricant, which was named moisture-removing (Water Of displacement), and appropriated to it number 40 (about the number of attempts). Now familiar as far as all aerosol bottle with the blue-yellow label can be found before 80% of American houses. However, not only American - goods is extended in more than 120 countries of world.

Question: Where it is possible to use “WD-40”?

Answer: Its basic task - drainage based on the mechanical surfaces of units, components or aggregates and their protection from the rust and the corrosion. The principle of operation “WD-40” is simple, but it is extremely effective: it penetrates those parts of the metal constructions, which are covered for the sake of rust, are lubricated they and are removed the formed congestions before the rusted or frozen through mechanisms. “WD-40” - ideal fellow-traveller for the drivers, processed by them the hinges of doors cease to squeak. Preparation easily manages the rust, which was being formed also inside the door lock of wicket, garage, before “the joints” of lawn mowers, pumps. Electrical contacts will be for a long time protected based on the formation on them of rust, if we cover for the sake of their thin layer “OF WD-40”, which itself, by the way, is not the conductor of electricity. If water entered into the engine of electric generator, short circuit or loss of electrical conductivity because of the moisture occurred, direct the jet “OF WD-40” down to the distributer, junction boxes, contacts, and engine is brought through several minutes.

BARRIER FROM ACTIVE ZINC

Question: What such “[zinganizatsiya]”?

Answer: So is called the method of galvanizing with the aid of the single-component (ready to application) zinc composition Of zinga (production of the Belgian company Of zingaMetall).

All layers Of zinga, after whatever time they were brought, merge beside one united zinc layer. This makes it possible to, in the first place, assign the periods of the operation of coating from 10 to 50 years (1-6 m of zinc “it burns” per year with different atmospheric conditions). In the second place, always there is the possibility to accomplish a local, “point” repair both of new and long ago “[ozingovannykh]” or zinc-coated by any other method surfaces.

Question: How to work with coating Of zinga?

Answer: It is brought by usual dispersion, brush or roller. To work with it is possible over a wide range temperatures, also, with the high humidity both before to the shop and on the working area.

Sand blasting is optimum surface preparation. Old (rusted, previously painted or zinc-coated) surfaces can be purified by water jet under the high pressure.

Question: How does interact Zinga with other paints?

Answer: With the data by coating the majority of varnish-and-paint compositions couple without any surface preparation. Above Zinga can be brought polyurethane, epoxy, vinyl, oil, synthetic (with exception of alkyd), water-soluble paints. Can be covered for the sake of other compatible paints after only it is 2nd 8 hours depending on drying conditions.

Question: Are there such coatings, above which it is possible to produce welding?

Answer: Without any risk, connected for the sake of the qualitative characteristics of the weld, it is possible to produce welding they began, covered for the sake of the anticorrosive composition Of zinga.

The fact is that this coating ensures the cathode protection of the welds. After welding, cleaning the welds, it is possible to easily apply Zinga for obtaining the active united protective coating, however zinc-coated the welded constructions.

Question: Are such the characteristics of coating [Cheral]-01?

Answer: This is - thin-film zincsilicate coating beyond the water base. It ensures simultaneously and active (cathodic), analogous down hot galvanizing, and passive (barrier) as in paints, the protection of ferrous metals from the corrosion.

The field of application of coating [Cheral]-01 is extensive. It is possible to protect by it from the corrosion of the surface of steel constructions with their contact with the atmosphere or the water (capacity of drinkable and fresh water, mast of electric power lines, heat exchangers, fire tubes, the system of hot and drinkable water supply and the like). [Cheral]-01 restores the damaged sections the of previously zinc-coated surfaces.

Rapid drying of the substituted layer and absence of harmful evaporations minimizes the requirements of sanitary-epidemiological services at the point of the organization of technological process, especially, with performing of work in the closed accomodations.

BIOCORROSION: BRIEF LIQUIDATION OF ILLITERACY

Question: Why do occur the biodamages of construction?

Answer: The circle of the [biopovrezhdayushchikh] agents is sufficiently wide, beginning from the bacteria, fungi, lichens, mosses and concluding by fishes, birds and mammals.

The objects of biodamages before the building are wood, brick, concrete, metal, hardware, materials on the basis of polymers and others

Question: How are formed biodamages?

Answer: Studies established that physical, chemical and wetware of the corrosion of mortars and concretes are located before the close interrelation. Since concrete is capillary-porous body, this gives the possibility to microorganisms easily to settle beyond the surface and then to be extended in depth, causing by the products of its vital activity corrosive processes. The basic processes of destruction are caused as far as the action of the acids, isolated before the process of the vital activity of microorganisms.

Question: Why metals do fear microbes?

Answer: Protection from the rust of the reinforcement of reinforced concrete occupies important place before the construction practice. Studies of scientists established that the bacteria ruinously act on the steel the reinforcement of ferroconcrete articles. “The participation” of microorganisms before the corrosion of metal consists before its bacterial depolarization.

Question: What does present by itself the corrosion of concrete?

Answer: The corrosion of concrete - this is worsening in characteristics and properties of concrete as a result of washing out or leaching from it:

• the dissoluble component parts (corrosion of the first form);
• the formation of the products of corrosion, which do not possess the binding properties (corrosion of the second form);
• the accumulation of the relatively insoluble crystallizing salts, which increase the volume of its solid phase (corrosion of the third form).

Question: How it is possible to protect concrete?

Answer: The protection of structures from the biodamages assumes taking the following measures:

1. Preventive-operational:

• strengthening ventilation for the purpose of reduction in the humidity of air and concentration of the gases, which facilitate the development of dangerous microorganisms;
• hermetic sealing for the same purpose of technological equipment;
• periodic cleaning and the disinfection of the surface of constructions;
• the neutralization of aggressive media.

2. Design:

• giving to the surface of the constructions of the form, which prevents the accumulation on it of the organic matter, which are powerful to serve after food for the microorganisms;
• the device of the inclines of sexes and abducting chutes for the sewage liquids.

3. Construction- technological:

• putting beyond the concrete surface of paints; the revetment by different plates;
• reduction in the permeability of concrete;
• the application of materials, steadfast to the action of the products of the vital activity of microorganisms, predominantly down the acids.
