Our range of services includes such an important process as galvanizing.
Corrosion is a natural and inevitable process, which, however, can be minimized.
Zinc – coated metal layer of zinc to protect against corrosion. Suitable for flat or with a slight curve surfaces not exposed to mechanical stress.
The protection method based on the principle that the zinc in the coating composition comes into the first reaction corrosion without exposing the metal itself.
Zinc is able to protect iron from rust, which inevitably occurs during the operation of metal items. And this protection is not a purely mechanical nature – together with iron zinc forms a galvanic couple, and zinc with oxygen interaction results provide even more protection – zinc on the surface crust is formed.
Anti-corrosion coatings using zinc and galvanizing it, have a number of obvious advantages:
– An increase in metal service life to 60 years;
– Covering the entire product evenly
– Resistance to delamination
The electroplating method – electrochemical deposition of zinc metal on the surface of the zinc in the electrolyte solution
Hot-dip galvanizing – is characterized by highest protective properties metallization.
Thermodiffusion galvanizing – zinc coated product vapor at a high temperature in a protective atmosphere of hydrogen.
Cold tsinkovanie- applying to the prepared surface of methods used for conventional polymeric inks, special composition containing zinc powder, thereby forming a coating having properties inherent Hot dip galvanized and polymeric coatings.
Gasdynamic galvanizing – the application of supersonic flow on the surface of any configuration, is characterized by high adhesion.
One of the main, are in high demand among the customer service that our company provides, it is a cold and hot-dip galvanized steel.
Hot tsinkovanieproizvoditsya in accordance with GOST 9.307-89 State standard.
Before applying the zinc layer of the product goes through the following preparation steps:
1. Degreasing – removing oil from the surface of the product and other synthetic contaminants.
2. The etching – removal of rust and scale, as well as the chemical activation of the surface.
3. Washing – wash the solid metal particles from the surface and to prevent product transfer solutions of hydrochloric acid fluxing bath.
4. Fluxing – prevent the formation of oxides on the surface of the product, removal of residual salts.
5. Drying – made complete drying of products after the chemical treatment.
Hot-dip – coated layer of zinc metal to protect against corrosion product by dipping in a bath of molten zinc at about 460 ° C. Under the influence of atmospheric pure zinc reacts with oxygen and forms zinc oxide, followed by reaction with carbon dioxide and the formation of zinc carbonate (ZnCO3), usually matte gray sufficiently rigid material, stopping further corrosion of the material.
Hot-dip galvanizing is considered one of the most reliable, cost-effective and therefore common methods of protecting iron and steel from corrosion.
For hot-dip galvanizing of steel structures it is undoubtedly the most common type of coating. The thickness of the zinc layer ranges from 30 to 100 microns.
This method provides a high quality protective zinc coating with a predetermined thickness, which is able to successfully resist corrosion for decades. Also, improved characteristics of the finished product – it aesthetic appearance and much more effectively resists wear during operation. In addition, there is the possibility of a more detailed visual inspection of the surface state of the product, while the other protective coating (eg, paint) only mask defects that in the next year or two will still make themselves felt.
This method of galvanizing has proven itself as the most simple and affordable.
– The ability to weld to cover
– To galvanize the spot welds, repair defects
– Ecological purity
– Protects the steel from corrosion in 6 times longer than other methods galvanizing
The best way to protect metal surfaces from corrosion and to increase their life – this is the use of special anti-corrosion coating.
The special anti-corrosion coating of high reliability concerns tsinkonapolnenny soil, which is a zinc powder with polyurethane components.
The main advantage tsinkonapolnennogo soil is that it significantly enhanced barrier properties and combination tsikovogo polyurethane components.
Features zinc primer:
– Resistance to mechanical damage
– Adhesion strength with the material
– fire safety
– Resistance to temperature changes
