The LA2 spray gun from Zhengzhou Lijia embodies nearly twenty years of profound experience and technical expertise in the field of thermal spraying. Its design closely revolves around the principles of efficiency, precision, and safety, providing excellent solutions for a wide range of thermal spraying needs.
The LA2 gun has a unique advantage in fuel usage, utilizing propane as fuel and air as the oxidizer, a safe combustion mode that greatly reduces usage risks. The flame velocity of the spray gun is outstanding, offering flexible and powerful support for various spraying tasks. The innovative axial center powder feeding method allows the powder to dissolve better and distribute evenly throughout the flame, significantly enhancing coverage efficiency and coating quality, ensuring excellent performance with high bond strength and low porosity.
1. High safety performance: Propane is used as fuel and accelerant is air, which is the safest combustion mode in the gas model on the market.
2. Good quality of powder feeding and coating: The axial center powder feeding method is adopted, so that the powder can be better dissolved and evenly distributed in the whole flame, which improves the coverage efficiency, the coating binding strength is high, and the porosity is less than 1%.
3. Convenient and intelligent operation: The equipment adopts a full closed-loop automatic control structure, and the gas control components are pressure sensors imported from the United States and pressure regulators imported from Japan, and the pressure can be monitored in real time and automatically reach the process set value; The panel is operated by a touch screen and has the function of storing and calling process recipes.
4. Low temperature rise of the workpiece: The temperature rise of the workpiece is reduced by half during supersonic spraying, which can effectively ensure that the workpiece is not deformed.
5. Wide range of spraying materials: It can spray low-temperature, medium-temperature and high-temperature materials such as copper powder, aluminum powder, iron-based powder, nickel-based powder, tungsten carbide powder, superviscous powder, ultra-fine powder.
6. Concentrated flame beam: The flame beam is more concentrated, which effectively improves the deposition rate of powder.

As the core of supersonic flame spraying equipment, HA-2000 supersonic flame spraying system is matched with LA2 series propane air supersonic flame spray gun, this series of spray guns adopts the latest international supersonic spray gun design and structure innovation and optimization, the spray gun is the most stable and reliable universal air supersonic flame spray gun, the spray gun is in use, only propane or propylene as fuel, high safety.Customers can also choose to add hydrogen for use, when hydrogen is not used, the parameters of the hydrogen parameter bar in the parameter setting interface are set to 0 value, when hydrogen needs to be used, the starting value, running value, duration and ramp parameters of the hydrogen parameter bar can be set in the parameter setting interface, and the hydrogen flow rate will automatically ramp up to the operating value when the equipment starts. Powder deposition rate can be increased. In addition, the gun can also be used as a pre-treatment blasting of the workpiece.
The main structure of the LA2 spray gun is the way in which the combustion chamber is connected to the first-stage combustion nozzle, and part of the air is used to support combustion, and part of it is used to cool the gun body and directly discharge it out of the gun, because the flame gas after combustion instantly expands several times, and the inside of the gun body has a stronger impetus for the powder particles, so that the flight speed of the particles is higher, and the coating presents excellent characteristics, such as low porosity and higher coating hardness.
