Powder flame spray is a process in which powder is used as feed material to provide a coating on the substrate. A powder flame spray gun is a lightweight thermal spray gun for thermal spraying. Fuel gases such as acetylene, propane, hydrogen are used with oxygen. Sometime LPG is used at the place of these gases.
Compressed air is used for cooling purposes and increases the velocity of molten metal to impinge on the component. In powder, a flame spray gun gas flow meter is used to check the flow of oxygen and acetylene. The required ratio of oxygen and acetylene gas is maintained to provide a coating on the substrate.
Various Kind Powder Flame Spray
Powder flame spray gun 5P-II
It is a lightweight and handheld spray. This includes a built-in powder canister so no requirement for an external powder feeder. These guns used to apply the coating for a variety of applications such as corrosion protection, surface repair, dimensional restoration, and wear resistance.
These powder flame sprays suitable for all-purpose use and can apply a wide range of coating material such as ceramics, self-fluxing alloys, and conventional material. 5P-II has high deposit and spray rates and also economic. It is light in weight and has a pistol grip handle for operator safety and comfort.
Powder flame spray gun 6P-II
This type of gun has been designed for high volume production demand and consistent coating results. gun 6P-II is used to solve many surface problems like machine element repair, corrosion protection, dimensional restoration, and wear resistance.
This powder spray gun has a high spray rate with low gas consumption and a high deposition rate. This spray gun also uses for a wide range of coating materials such as alloys, ceramics, and self-bond materials. It is simple to use and maintain.
Process Of Powder Flame Spray Gun
The heat generated by the combustion of a fuel gas, usually acetylene or propane with oxygen, is used to melt the spray coating material in flame spraying. A consumable, usually a powder or wire, is heated and propelled onto a substrate to form a surface coating in this process.
