As galvanized metal at home

BTo protect the metal from corrosion and harmful effects of atmospheric precipitation in modern technology is most often used galvanizing (zinc coating). The main advantages of this method is its small cost of and high efficiency.

The principle of action of zinc:
Interacting with atmospheric oxygen at the surface a zinc oxide film which protects the metal from contact with moisture.

FROMamym available ordinary person and simple method of applying the protective zinc layer on the metal is corroded cold galvanizing.

Xolodnoe galvanizing - a protective coating in a liquid form (zinc paint). It is important to understand that this is not the paint with the addition of zinc, namely metal in liquid form.

Technology cold galvanizing.

- | STEP 1 | -
Stripping metal.

ABOUTgromnuyu role in the preparation of cold galvanizing metal plays - before the application of zinc carefully smooth out all zasentsy, irregularities and rust metallic brush!

PAfter you have cleared the metal brush broom sweeping from him all the metal dust that remained from the stripping. Only then can you begin the process of galvanizing.

Fidky zinc typically includes two components are often supplied in separate containers - zinc powder and binder liquid component. It is commercially available and ready to spray, but is much more effective two-component, as you yourself can adjust the density of the mixture and control the zinc content in the mixture.

PBefore application the powder is mixed with the liquid. The proportions of "powder" - "Connection" is generally dependent on the manufacturer. Optimal proportions - from 1: 1 to 3: 1.

Xolodny zinc is applied to the metal only at positive temperatures and low humidity in a room protected from the wind.

Important. Because of the high density compositions and quickly separated immediately prior to application they must again and mix again until homogeneous.

Fidky zinc conveniently applied through a spray nozzle, it is less convenient - from an aerosol can or wide paint brush, but the last way - the least preferable.

CInca coated by the method described above is from 3 to 4 years, after which cold galvanizing procedure can be repeated.
