Benefits of zinc spray with respect to hot-dip galvanizing
- Simple process and compact design that does not require a particular specialization of labor
- The plants for electric arc can spray zinc and / or aluminum, copper e/o Brass while the zinc galvanizing bath only
- Speed of execution work 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 deformation of the support because the temperature at which occurs the adhesion zinc / iron is 150 ° C
- Small initial investment and maximum flexibility
- Plant carrellabile for 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 comparable to those of the galvanizing bath
- Ability to deposit from 30 a 500 micron Zinc
- The spraying zinc esalta and garnish of 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 paint because 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 environmental and 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 the coating on Zn e / o Al (effect duplex) the anti-rust protection than 35-50 years
