Hot-dip galvanizing technology is a method of protection against wear and corrosion of metal by coating with a layer of zinc, which significantly extends the life of the metal product. The process takes place by immersing a metal wire in a bath of molten zinc at a temperature of about 450 degrees.
Stages of hot dip galvanizing
The process involves several steps. Consider in more detail:
1. Degreasing by immersion in a hot solution of phosphoric acid at a temperature of about 50 degrees, which washes away dirt and grease.
2. Digestion in an aqueous solution of hydrochloric acid at a temperature of 30 degrees.
3. Final rinsing in technical water at a temperature of 30 degrees, cleaning from dust.
4. Fluxing in an aqueous solution of zinc chloride and ammonium at a temperature of 60 degrees.
5. Drying in a chamber with recirculation of hot air at a temperature of 90 degrees, which ensures complete drying.
6. Galvanizing by the method of forming bonds between steel and zinc by immersion for a few minutes at high speed in a ceramic bath with molten zinc at a temperature of 450 degrees. The rotation of the drum provides the flow of zinc mass for high-quality uniform coating up to microcracks.
7. Centrifugation by spinning the drum to remove excess zinc.
If you follow all the stages of galvanizing, the mesh of this wire will last for decades while maintaining the original appearance, without the formation of rust.
Advantages of buying galvanized mesh
Pros:
- corrosion resistance, because the coating creates a barrier between the environment and the material;
- uniform application of electrochemical coating, even on damaged areas of metal;
- the surface is more resistant to mechanical damage;
- zinc layer has greater wear resistance than paint;
- galvanize metal structures - is the possibility of use in aggressive environments, marine, in areas with humid climates;
- the method of hot-dip galvanizing forms an environmentally friendly coating that is safe for the environment.
