Benefits

Benefits of zinc spray with respect to hot-dip galvanizing

  • Simple processand compact design that does not require a particular specialization of labor
  • The plants for electric arccan spray zinc and / or aluminum, copper e/o Brass while the zinc galvanizing bath only
  • Speed ​​of executionwork without having to wait the time it takes for hot dip galvanizing
  • Poca mano d'opera: l 'operator that performs the sandblasting can also perform the galvanizing
  • Reduced energy consumption: 10 kwh
  • No deformationof the support because the temperature at which occurs the adhesion zinc / iron is 150 ° C
  • Small initial investment and maximum flexibility
  • Plant carrellabilefor which you can perform work in situ rehabilitation of corroded artifacts
  • Zinc consumption need to(only when working), unlike the galvanizing bath whose tanks contain molten zinc up 600 tons (Financial immobilisation up to € 1,2 billion and high energy costs)
  • Reduced pollution: are only required spraying booth and filtration plant. There are acids or dirty water to be disposed
  • Production costs comparableto those of the galvanizing bath
  • Ability to deposit from 30 a 500 micronZinc
  • The spraying zinc esalta and garnishof the artifact in iron; which does not happen with the Hot-dip galvanizing where the patterns are not very visible and artifacts are galvanizing slag and ash to be removed
  • The coatings are pure zinc and porous, Easy to fill with sealant
  • Easy to paintbecause the carry-over of zinc is slightly porous

Comparison with the painting

  • is sprayed over the entire : iron, cement, plastic, tissues, film, wood, glass, Marble, resins
  • less impact environmentaland more safety in the workplace
  • ease of use; there is no problem of mixing products
  • high productivity: 30 kg Zn covering ca. 45 m2 / h non Ferro
  • greater adherence and best response of the coating at high temperatures
  • Three coats of paint have a duration of 7 years and require a laying cycle of 3 days; Zn over 25 years
  • Applying thecoating on Zn e / o Al (effect duplex) the anti-rust protection than 35-50 years
