Zinc Spray Gun in South Africa

Zinc Spray Gun

The zinc spray gun is additionally referred to as a metal spray gun, thermal spray gun, aluminum spray gun, copper coating spray. When using aluminum wire than it’s called an aluminum spray gun. and when copper is sprayed then it's called a copper spray gun. The sprayed zinc gun coating is rough and slightly porous, with a selected gravity of 6.4, related to zinc metal at 7.1. Zinc corrosion products Limitations include cost, difficulty in applying, lack of coating uniformity (particularly at corners and edges), and therefore the requirement for a clean steel surface. Zinc-rich paints should stay top coated in severe environments. The qualities of organic zinc-rich paints depend upon the solvent system. Many coats could also be applied within 24 hours without cracking. Zinc-rich paints are usually associated with retouch galvanized steel that has been damaged by welding or severe mechanical impact.

Zinc Spray Coating

The zinc spray gun is thermally sprayed using either an electrical arc or a combustion flame process. the electric arc process, which allows higher deposition rates with an improved economy, uses two consumable(anode and cathode) zinc wire electrodes. The wires are given opposite electric charges and are fed approximately to take care of the electrical arc, causing the wires to melt. The molten material is sprayed onto the prepared surface with the assistance of compressed air.

In the combustion process, one zinc wire, or a source of zinc powder, is fed into an oxy-fuel flame, which melts the zinc which is then atomized by compressed air for applications of zinc and zinc alloy thermal sprayed coatings are often easily controlled by the equipment operator to supply a thickness of fifty – 500 microns (.002” to .020”). this is often important once we considering atmospheric conditions which will dictate the protective thickness required as really long life or highly corrosive conditions necessitate a thicker coating. Zinc thermal spraying may be a method where zinc or zinc alloys are melted then sprayed onto a prepared substrate, creating a layered coating. Thermal gun spraying may be a highly effective and proven process of corrosion prevention, giving galvanic also as barrier coating protection to iron and steel.
