Frequently Asked Questions

Q: How does the 3D scanning system improve painting quality?

The 3D scanning system intelligently identifies the complex geometry of steel components from all directions, allowing the system to calculate the precise path and volume of paint required, ensuring total coverage without over-spraying.

Q: What is the benefit of the two-stage filtration system?

The two-stage design, utilizing a nine-grid spoiler and glass fiber cotton, captures paint mist more effectively. This not only protects the environment by meeting emission standards but also extends the lifespan of the filtration materials.

Q: Can this system handle different sizes of steel structures?

Yes, the system is equipped with various styles of load-bearing brackets and different specifications of chain cars, making it highly versatile for a wide range of heavy steel component dimensions.

Q: How is the drying temperature controlled in this system?

Temperature is managed via an electric contact temperature sensor that automatically adjusts the output power of the natural gas combustion furnace, maintaining a stable range between 40-80 ℃.

Q: What is the average coating thickness achieved by the line?

Depending on the coating properties and climate settings, the system typically achieves a professional surface drying effect with a single coating thickness of approximately 80um.

Q: Is the filtration material safe and durable?

The glass fiber paint blocking cotton is specifically developed for paint mist purification. It is flame-retardant, possesses a large capacity for pollutants, and is designed for low-cost replacement.
