The zinc spray gun is a versatile process that melts Zinc or Alloy metals, and then rapidly propels the molten metal particles onto a prepared substrate, creating a lamellar or layered coating. Metalizing Gun, or Thermal Spraying as it is often called, is a highly effective and proven method of corrosion prevention, giving galvanic as well as barrier coating protection to iron and steel. Zinc spraying, or metalizing, is accomplished by feeding zinc in either wire or powder form into a heated gun, where it is melted and sprayed onto the part using combustion gasses or auxiliary compressed air to accommodate the required velocity.

Specification of Zinc Spray Gun

Zinc Spray Gun Manufacturer

The zinc spray gun is also known as a metal spray gun, thermal spray, aluminum, copper coating spray. When using aluminum wire then 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 specific gravity of 6.4, associated with zinc metal at 7.1. Zinc corrosion products Limitations include cost, difficulty in applying, lack of coating uniformity (particularly at corners and edges), and 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 on the solvent system. Many coats may be applied within 24 hours without cracking. Zinc-rich paints are usually related to touch-up galvanized steel that has been damaged by welding or severe mechanical impact.

Zinc Spray Gun Applications

Anodic protection is provided by a zinc or aluminum metalized covering that sacrificially protects the underlying steel. Because the metalized coating is in direct touch with the steel without “interference” from the paint binder, it is more effective and efficient than zinc paint.

Chemical Resistance: Due to the creation of a strongly adhering oxide layer, metalized coatings (especially aluminum) obtain some level of chemical resistance. A topcoat is also applied to give additional protection or to achieve the desired aesthetic.

Corrosion Resistance Because low carbon, unalloyed steel, and cast iron are prone to rust, they require constant surface protection. Flame-sprayed aluminum wire or zinc coatings can also be used to achieve this.

Selection of Zinc Coatings

After deciding to use a zinc coating for corrosion protection, some factors must be considered to ensure the proper coating is selected for the intended application and service environment.

• The initial cost of the coating
• Coating life to first maintenance
• Cost of Maintenance

Zinc Spray Coating

An electrical arc or a combustion flame technique is used to thermally spray the zinc metalizing spray gun. The electric arc technique uses two consumable zinc wire electrodes (anode and cathode), which enables for higher deposition rates while saving money. The wires are given opposing electric charges and fed roughly to prevent an electrical arc from forming, causing the wires to melt. With the help of compressed air, the molten substance is sprayed over the prepared surface.

One zinc wire, or a source of zinc powder, is fed into an oxy-fuel flame, which melts the zinc, which is subsequently atomized by compressed air for zinc and zinc alloy applications. The thickness of thermal sprayed coatings can frequently be easily regulated by the equipment operator, ranging from fifty to 500 microns (.002″ to.020″).

This is particularly significant when assessing the protective thickness necessary, as extremely long life or highly corrosive environments require a thicker coating. Zinc thermal spraying is a method of generating a multilayer coating by melting zinc or zinc alloys and spraying them onto a prepared substrate.
