Repair of steel structures - Corrosion prevention, etc.

Depending on your needs and state of repair of the surface coating may include clearing, leveling the corrosive damage, surface protection through the imposition of protective coatings.


BLASTING-it is a technological process involving cleaning or shaping any surface with a stream of compressed air (or fluid - blasting used in dentistry) with the addition of hard particles.

The effect is similar to sand blasting, grinding, however, cleared the surface is usually much smoother and there are no problems with cleaning awkward corners or curves.
Sandblasting was patented by Benjamin Tilghmana 18 October 1870 year.
During the blasting particles striking the sand (usually purified by sieving) can get into the lungs employee, what with working longer may cause one of the diseases pylicznych. Therefore, sanding can be done only by following the strict safety rules: must be used, provided with protective clothing, ventilation and fresh air to breathe (which is seen in first photo).

Sandblasting can also be used for other, enough particulate materials: glass, metal, dry ice, garnet (mineral), slag and even ground coconut shell pieces and other plants, which allows for the specific appearance of the machined surface.

First Protective Coating - This layer is generated on the surface of metal or other material of construction to protect it from corrosion. Coatings are classified on the basis of:

- Mechanism of protection (eg insulation, anode, cathode)
- Method of application (eg, chemical, diffusion, immersion)
- Composition (eg, oxide, metal, lubricants)
- Persistence (eg, time)

Shell stands out:

* Anode - showing the corrosive environment in the lower potential than the potential of the protected metal
* Chemical - obtained by chemical reaction of metal with the corresponding solutions without the electric current
* Time - applied to metal or produced in chemical reactions occurring on the surface, persist only for a limited time, eg during transport and storage
* Diffusion - obtained by diffusion of atoms of a substance that protects from the protected metal (such as carburizing, nitriding, carbonitriding, titanium)
* Electrolytic (galvanic) - produced on the surface of metal by electroplating
* Emaliarskie - obtained by the superimposition of the metal being protected non-metallic substances (usually these are silicate compounds), which is then fused by firing
* Cathode - showing in a corrosive environment, a higher potential than the potential of the protected metal
* Condensation - obtained by reduction of metal without the use of an external source of electric current
* Conversion - formed on the metal surface by chemical or electrochemical machining (eg, phosphate)
* Paint - painting products obtained by
* Metallization - obtained on the surface of metal by metal spraying and plating
* Non-metallic insulation - separating the metal from corrosive non-metallic layer
* Passivation - formed tight layers of metal products of their reaction with chemically active substances, occurring in the environment (the process of passivation
* Lubricating - obtained by applying the metal layer of grease niewysychającej
* Anodic oxide - obtained by the electrochemical oxidation of the metal in the process of anodizing
* Immersion (dip) - obtained by immersing the protected product in a different metal that protects the molten metal (eg zinc on steel products is an active anode coating, which means that after damage the continuity of the surface is still protected as cathode)
