What's liquid spraying technology going on?

Liquid spraying technology is constantly developing and optimizing, bringing about a series of changes and improvements.‌
Firstly, the optimization of liquid spraying technology in reducing energy consumption, raw material usage, and overall material performance requirements demonstrates its important role in the national economy. Through thermal spraying technology, it is possible to repair and reuse parts with excessive wear and tear, which not only helps to effectively utilize resources but also reduces the burden on the environment.
Secondly, the advancement of ultrasonic atomization spraying technology, especially in the treatment of high viscosity liquids, has demonstrated significant technological progress. High viscosity liquids face challenges in ultrasonic atomization spraying, such as poor atomization effect, uneven formation and distribution of water droplets. By improving the solution, such as changing the liquid temperature, increasing the ultrasonic power and reducing the operating frequency, and using dual flow or multi flow ultrasonic atomizers, the atomization efficiency and uniformity of high viscosity liquids can be effectively improved.
In addition, the precise control of the three stages of spray gun atomization - atomization, diffusion, and settling - ensures that the coating forms a smooth and uniform coating layer during the settling process, providing strong support for automotive maintenance and painting work, ensuring the quality and efficiency of the final product.
In summary, the development of liquid spraying technology not only improves resource utilization efficiency, reduces energy consumption and raw material use, but also solves the problem of handling high viscosity liquids through technological innovation. By accurately controlling different stages of the spraying process, it improves spraying quality and efficiency, thereby promoting the progress and development of related industries.
And Electrostatic spraying has multiple advantages, including improving coating utilization, improving working conditions, increasing labor productivity, enhancing coating corrosion resistance and durability, etc.‌
Improving paint utilization: Electrostatic spraying utilizes electric field force to adsorb negatively charged paint particles onto positively charged workpiece surfaces, forming a uniform coating film. This method can greatly improve the utilization rate of coatings and reduce waste. Typically, the utilization rate of coatings can reach 80% to 95%.

Improving working conditions: Electrostatic spraying reduces the scattering of paint mist, improves the working environment, reduces the labor intensity of operators, and is beneficial for improving work efficiency and protecting workers' health.
Improving labor productivity: Electrostatic spraying can achieve automation of the spraying process, thereby increasing labor productivity. Compared with ordinary spraying, it can improve work efficiency by 10% to 100%.
Enhance the corrosion resistance and durability of coatings: Coatings formed by electrostatic spraying have good adhesion, mechanical strength, and corrosion resistance, which can significantly improve the corrosion resistance and durability of workpieces, especially suitable for workpieces that require long-term exposure to air.
In addition, electrostatic spraying also has the advantages of good construction environment and working conditions, and good spraying effect on the corners of complex workpieces. However, there are also some limitations, such as specific requirements for the conductivity and volatility of coatings and solvents. It is mainly suitable for metal workpieces with good conductivity, and special treatment is required for non-conductive materials.
What are the advantages of Hongda electrostatic spray gun?
The advantages of Hongda electrostatic spray gun mainly include improving spraying efficiency, saving paint, reducing paint waste, lowering costs, and environmental protection effects. ‌
The design of the Hongda electrostatic spray gun combines ergonomic principles, making the gun lightweight and durable, capable of long-term use without fatigue, thereby improving spraying efficiency. In addition, this spray gun can reduce manual spraying time, achieve rapid spraying, and is particularly suitable for large-scale production situations. Electrostatic spraying technology uses a high-voltage electrostatic field to direct negatively charged coating particles in the opposite direction of the electric field and adsorb them onto the surface of the workpiece. This technology not only allows for thicker coatings to be obtained in one coating, but also significantly reduces poor productivity and improves product surface quality. The uniform atomization characteristics of the Hongda electrostatic spray gun result in good surface leveling and better coating, further improving product quality.
In addition, there are some other features in the design and use of Hongda electrostatic spray guns:
Reasonable design: The structure design of Hongda electrostatic spray gun is reasonable, combined with ergonomic principles, making the spray gun lightweight and durable, and able to be used for a long time without fatigue.
Uniform atomization: When using a Hongda electrostatic spray gun for spraying, the atomization is uniform, resulting in good surface leveling and better coating, thereby significantly reducing poor productivity.
Improve efficiency: By improving spraying efficiency and reducing manual spraying time, Hongda electrostatic spray guns can achieve rapid spraying, especially suitable for large-scale production situations.
Environmental protection effect: By saving paint and reducing paint waste, Hongda electrostatic spray guns have achieved cost reduction and environmental protection effects.
In summary, through its unique design and technological advantages, the Hongda electrostatic spray gun not only improves spraying efficiency and quality, but also achieves the goals of cost savings and environmental protection
