Spray Galvanizing
Zinc Thermal Spraying also known as spray galvanizing, this process is an anti-corrosive protection system used for very long life coating requirements. Spray galvanizing technology is spraying of pure zing metal wire on blasted surface by mean of thermal spray process. In this process, the zinc durable coating.
Zinc is thermal sprayed using either an electric arc or a combustion flame process. The electric arc process, which allows higher deposition rates with improved economy, uses two consumable zinc wire electrodes. the wires given opposite electric charges and are fed close together to maintain an electric arc, causing the wires to melt. The molten material is sprayed coating onto the prepared surface with compressed air. Zinc and zinc alloy thermal sprayed coatings can be easily controlled by the equipment operator to achieve better performance.
Benefits Of Spray Galvanizing
➢ Good Corrosion Protection
➢ Food Grade Coating
➢ Long Material Life
➢ No Size Limitation
➢ No Steel Restrictions
➢ Applied in Field
➢ No Heat Affected Zone
Process of Zinc Thermal Spray
The metalizing process starts with preparing the surface of the product. Then a metal wire is melted in metalizing spray gun these molten metal is propelled on a coating surface by using atomized air to form the coating. A layer of sealant is applied over the coated surface for finishing and aesthetic look.
Surface cleaning
Sandblasting is process of roughing and cleaning a hard surface by forcing solid particles across that surface at high speeds using compressed air.
Thermal spraying
Thermal spraying is a process where metal or metal alloys are melted and then sprayed onto a prepared substrate, creating a thin layered coating of about 50-500 Microns.
Sealant application
Sealant application is a painting technique in which a device sprays coating material through the air onto a surface.
