Technology cold galvanizing enamel contain zinc

Types metal galvanizing

There are several ways to merge the zinc and steel to obtain a corrosion resistant material:

• hot;
• galvanic (also known as electrochemical or electrolytic);
• thermal diffusion;
• cold (painting);
• gas-thermal (evaporation).

The first three options are feasible only in large-scale production, they require significant industrial capacity, energy consumption and waste treatment that are incompatible with residential use.In addition, all these methods have limitations in size of products.Steel galvanizing after this gets on the construction market as a finished product.

Gas-thermal method is used for galvanizing of large metal structures that can not cover the rust inhibitor industrial way of size.Surface turns scaly, porous and requires additional processing of paint compositions, but after such a combination of steel construction will last about 30 years.

Cold galvanizing - the only one available in the home and is not limited in the size of the workpiece.However, he is not inferior to the industrial galvanized steel in many ways.

Enamel contain zinc metal

Application of soil or enamel with a zinc content - this is a cold galvanizing.As a part of the dried enamel sprayed zinc content reaches 89-93% (the higher the zinc content, the more reliable protection against corrosion in the finished product).

cold galvanizing technology has its advantages relative to all other methods:

• can do with their hands;
• suitable for machining of large metal structures or fixed;
• can independently adjust the thickness of the protective layer of zinc and saturation;
• with proper operation of several times the service life of hot-dip galvanized;
• has a decorative function.

However, there is this method of anti-corrosion treatment and cons:

• low resistance to mechanical damage;
• high toxicity of the composition during application;
• impossibility of disengagement damage (for hot-dip galvanizing, for example, any inaccuracies in the application of self-destruct due to the formation of zinc oxide).

weighing the "pros" and "cons" in the case of cold galvanizing technology, more and more people decide to try this method of treatment of steel with their hands.

As applied tsinkonapolnennaya anticorrosive enamel?

technology is quite simple and can be implemented successfully on the first try.To do this, follow the instructions drawn up by experts:

1. metal structures should be cleaned of dust, old coatings and rust, without using acids.Do not use harsh abrasives and brushes, to avoid damaging the galvanizing layer early.Excellent washing with water under high pressure.
   

   Note!On galvanized steel corrosion can also occur in the form of a whitish plaque, or yellowing of the metal.

2. surface is degreased in a standard way with the help of a solvent.
3. sure you must shake the ground or paint before applying.
4. Apply 2-3 turns of thin enamel layer, with each successive starting only after the complete drying of the previous one.

Note!It is important to apply the layers as evenly as possible to galvanizing the result was the same thickness over the entire surface without gaps.

After complete drying of the last layer, you get high-quality zinc coating and decorative ironwork.

Note!Apply cold galvanizing on the design better and faster just spray, but also suitable roller or brush.

Enamel Zinc: proven brand

building materials market is not experiencing shortages in zinc primer or enamel compositions.The most common among them:

• priming enamel and ZINOL primer ZINOL-SV, ZINOTAN, ZFES, ZFES MO, ZINEP, TSINOTERM, TSINMASTIK, SBE-111 "UNIPOL" AM, VL-023 VL-02, GF-021;
• coating material POLYTONE-SD POLYTONE-UR (UF), POLYTONE-AK.

choose among them is not difficult, according to its own requirements and materials costs.
